<p>There is a lot of software freely available for Unix-based
systems, which is usually available in form of the source code. Before
such software can be used, it needs to be configured to the local
system, compiled and installed, and this is exactly what The NetBSD
Packages Collection (pkgsrc) does. pkgsrc also has some basic commands
to handle binary packages, so that not every user has to build the
packages for himself, which is a time-costly task.</p>
<p>pkgsrc currently contains several thousand packages,
including:</p>
<div class="itemizedlist"><ul type="disc">
<li><p><a href="ftp://ftp.NetBSD.org/pub/pkgsrc/current/pkgsrc/www/apache/README.html" target="_top"><code class="filename">www/apache</code></a> - The Apache
web server</p></li>
<li><p><a href="ftp://ftp.NetBSD.org/pub/pkgsrc/current/pkgsrc/www/firefox/README.html" target="_top"><code class="filename">www/firefox</code></a> - The Firefox
web browser</p></li>
<li><p><a href="ftp://ftp.NetBSD.org/pub/pkgsrc/current/pkgsrc/meta-pkgs/gnome/README.html" target="_top"><code class="filename">meta-pkgs/gnome</code></a> - The GNOME
Desktop Environment</p></li>
<li><p><a href="ftp://ftp.NetBSD.org/pub/pkgsrc/current/pkgsrc/meta-pkgs/kde3/README.html" target="_top"><code class="filename">meta-pkgs/kde3</code></a> - The K
Desktop Environment</p></li>
</ul></div>
<p>...just to name a few.</p>
<p>pkgsrc has built-in support for handling varying dependencies,
such as pthreads and X11, and extended features such as IPv6 support on
a range of platforms.</p>
<div class="sect2" lang="en">
<div class="titlepage"><div><div><h3 class="title">
<a name="why-pkgsrc"></a>1.1.1. Why pkgsrc?</h3></div></div></div>
<p>
pkgsrc provides the following key features:
</p>
<div class="itemizedlist"><ul type="disc">
<li><p>Easy building of software from source as well as the creation
and installation of binary packages. The source and latest
patches are retrieved from a master or mirror download site, checksum
verified, then built on your system. Support for binary-only
distributions is available for both native platforms and NetBSD
emulated platforms.</p></li>
<li><p>All packages are installed in a consistent directory tree,
including binaries, libraries, man pages and other
documentation.</p></li>
<li><p>Package dependencies, including when performing package updates,
are handled automatically. The configuration files of various
packages are handled automatically during updates, so local changes
are preserved.</p></li>
<li><p>Like NetBSD, pkgsrc is designed with portability in mind and
consists of highly portable code. This allows the greatest speed of
development when porting to new a platform. This portability also
ensures that pkgsrc is <span class="emphasis"><em>consistent across all
platforms</em></span>.</p></li>
<li><p>The installation prefix, acceptable software licenses,
international encryption requirements and build-time options for a
large number of packages are all set in a simple, central
configuration file.</p></li>
<li><p>The entire source (not including the distribution files) is
freely available under a BSD license, so you may extend and adapt
pkgsrc to your needs. Support for local packages and patches is
available right out of the box, so you can configure it specifically
for your environment.</p></li>
</ul></div>
<p>The following principles are basic to pkgsrc:</p>
<div class="itemizedlist"><ul type="disc">
<li><p>“<span class="quote">It should only work if it's right.</span>”
— That means, if a package contains bugs, it's better to find
them and to complain about them rather than to just install the package
and hope that it works. There are numerous checks in pkgsrc that try to
find such bugs: Static analysis tools (<a href="ftp://ftp.NetBSD.org/pub/pkgsrc/current/pkgsrc/pkgtools/pkglint/README.html" target="_top"><code class="filename">pkgtools/pkglint</code></a>), build-time checks (portability
of shell scripts), and post-installation checks (installed files,
references to shared libraries, script interpreters).</p></li>
<li><p>“<span class="quote">If it works, it should work everywhere</span>”
— Like NetBSD has been ported to many hardware architectures,
pkgsrc has been ported to many operating systems. Care is taken that
packages behave the same on all platforms.</p></li>
</ul></div>

<a name="intro.platforms"></a>1.1.2. Supported platforms</h3></div></div></div>
<p>pkgsrc consists of both a source distribution and a binary
distribution for these operating systems. After retrieving the required
source or binaries, you can be up and running with pkgsrc in just
minutes!</p>
<p>pkgsrc was derived from FreeBSD's ports system, and
initially developed for NetBSD only. Since then, pkgsrc has
grown a lot, and now supports the following platforms:</p>

<p>There has been a lot of talk about “<span class="quote">ports</span>”,
“<span class="quote">packages</span>”, etc. so far. Here is a description of all the
terminology used within this document.</p>
<div class="variablelist"><dl>
<dt><span class="term">Package</span></dt>
<dd><p>A set of files and building instructions
that describe what's necessary
to build a certain piece of software using
pkgsrc. Packages are traditionally stored under
<code class="filename">/usr/pkgsrc</code>.</p></dd>
<dt><span class="term">The NetBSD package system</span></dt>
<dd><p>This is the former name of “<span class="quote">pkgsrc</span>”. It
is part of the NetBSD operating system and can be bootstrapped
to run on non-NetBSD operating systems as well. It handles
building (compiling), installing, and removing of
packages.</p></dd>
<dt><span class="term">Distfile</span></dt>
<dd><p>This term describes the file or files that are
provided by the author of the piece of software to
distribute his work. All the changes necessary to build on
NetBSD are reflected in the corresponding package. Usually
the distfile is in the form of a compressed tar-archive,
but other types are possible, too. Distfiles are usually
stored below
<code class="filename">/usr/pkgsrc/distfiles</code>.</p></dd>
<dt><span class="term">Port</span></dt>
<dd><p>This is the term used by FreeBSD and OpenBSD people
for what we call a package.
In NetBSD terminology, “<span class="quote">port</span>” refers to a different
architecture.</p></dd>
<dt><span class="term">Precompiled/binary package</span></dt>
<dd>
<p>A set of binaries built with pkgsrc from a distfile
and stuffed together in a single <code class="filename">.tgz</code>
file so it can be installed on machines of the same
machine architecture without the need to
recompile. Packages are usually generated in
<code class="filename">/usr/pkgsrc/packages</code>; there is also
an archive on <a class="ulink" href="ftp://ftp.NetBSD.org/pub/NetBSD/packages/" target="_top">ftp.NetBSD.org</a>.</p>
<p>Sometimes, this is referred to by the term “<span class="quote">package</span>” too,
especially in the context of precompiled packages.</p>
</dd>
<dt><span class="term">Program</span></dt>
<dd><p>The piece of software to be installed which will be
constructed from all the files in the distfile by the
actions defined in the corresponding package.</p></dd>

<dt><span class="term">pkgsrc users</span></dt>
<dd>
<p>The
pkgsrc users are people who use the packages provided by pkgsrc.
Typically they are system administrators. The people using the
software that is inside the packages (maybe called “<span class="quote">end
users</span>”) are not covered by the pkgsrc guide.</p>
<p>There are two kinds of pkgsrc users: Some only want to
install pre-built binary packages. Others build the pkgsrc
packages from source, either for installing them directly or for
building binary packages themselves. For pkgsrc users <a class="xref" href="#users-guide" title="Part I. The pkgsrc user's guide">Part I, “The pkgsrc user's guide”</a> should provide all necessary
documentation.</p>

<dt><span class="term">infrastructure developers</span></dt>
<dd><p>These people are involved in all those files
that live in the <code class="filename">mk/</code> directory and below.
Only these people should need to read through <a class="xref" href="#infrastructure" title="Part III. The pkgsrc infrastructure internals">Part III, “The pkgsrc infrastructure internals”</a>, though others might be curious,

<p>When giving examples for commands, shell prompts are used to
show if the command should/can be issued as root, or if
“<span class="quote">normal</span>” user privileges are sufficient. We use a
<code class="prompt">#</code> for root's shell prompt, and a <code class="prompt">%</code> for users'
shell prompt, assuming they use the C-shell or tcsh.</p>

<p>Before you download and extract the files, you need to decide
where you want to extract them. When using pkgsrc as root user, pkgsrc
is usually installed in <code class="filename">/usr/pkgsrc</code>. You are though
free to install the sources and binary packages wherever you want in
your filesystem, provided that the pathname does not contain white-space
or other characters that are interpreted specially by the shell and some
other programs. A safe bet is to use only letters, digits, underscores
and dashes.</p>
<div class="sect1" lang="en">
<div class="titlepage"><div><div><h2 class="title" style="clear: both">
<a name="getting-first"></a>2.1. Getting pkgsrc for the first time</h2></div></div></div>
<p>Before you download any pkgsrc files, you should decide
whether you want the <span class="emphasis"><em>current</em></span> branch or the
<span class="emphasis"><em>stable</em></span> branch. The latter is forked on a
quarterly basis from the current branch and only gets modified
for security updates. The names of the stable branches are built
from the year and the quarter, for example
<code class="literal">2007Q1</code>.</p>
<p>The second step is to decide <span class="emphasis"><em>how</em></span> you
want to download pkgsrc. You can get it as a tar file, via SUP,
or via CVS. All three ways are described here.</p>
<div class="sect2" lang="en">
<div class="titlepage"><div><div><h3 class="title">
<a name="getting-via-tar"></a>2.1.1. As tar file</h3></div></div></div>
<p>The primary download location for all pkgsrc files is
<a class="ulink" href="ftp://ftp.NetBSD.org/pub/pkgsrc/" target="_top">ftp://ftp.NetBSD.org/pub/pkgsrc/</a>. There are a
number of subdirectories for different purposes, which are
described in detail in <a class="xref" href="#ftp-layout" title="Appendix C. Directory layout of the pkgsrc FTP server">Appendix C, <i>Directory layout of the pkgsrc FTP server</i></a>.</p>
<p>The tar file for the current branch is in the directory
<code class="filename">current</code> and is called <a class="ulink" href="ftp://ftp.NetBSD.org/pub/pkgsrc/current/pkgsrc.tar.gz" target="_top"><code class="filename">pkgsrc.tar.gz</code></a>.
It is autogenerated daily.</p>
<p>The tar file for the stable branch 2007Q1 is in the
directory <code class="filename">pkgsrc-2007Q1</code> and is also called <a class="ulink" href="ftp://ftp.NetBSD.org/pub/pkgsrc/pkgsrc-2007Q1/pkgsrc-2007Q1.tar.gz" target="_top"><code class="filename">pkgsrc-2007Q1.tar.gz</code></a>.</p>
<p>After downloading the tar file, change to the directory
where you want to have pkgsrc. This is usually
<code class="filename">/usr</code>. Then, run <span class="command"><strong>gzcat
pkgsrc.tar.gz | tar xf -</strong></span> to extract the files.</p>
</div>
<div class="sect2" lang="en">
<div class="titlepage"><div><div><h3 class="title">
<a name="getting-via-sup"></a>2.1.2. Via SUP</h3></div></div></div>
<p>As an alternative to the tar file, you can get pkgsrc via
the Software Update Protocol, SUP. To do so, make sure your
supfile has a line
</p>
<pre class="programlisting">
release=pkgsrc
</pre>
<p>
in it, see the examples in
<code class="filename">/usr/share/examples/supfiles</code>, and that the
<code class="filename">/usr/pkgsrc</code> directory exists. Then, simply
run <span class="command"><strong>sup -v
<em class="replaceable"><code>/path/to/your/supfile</code></em></strong></span>.</p>

<div class="sect2" lang="en">
<div class="titlepage"><div><div><h3 class="title">
<a name="getting-via-cvs"></a>2.1.3. Via anonymous CVS</h3></div></div></div>
<p>To get pkgsrc via CVS, make sure you have <a class="citerefentry" href="http://netbsd.gw.com/cgi-bin/man-cgi?cvs+1+NetBSD-current"><span class="citerefentry"><span class="refentrytitle">cvs</span>(1)</span></a>
installed. To do an initial (full) checkout of pkgsrc, you first
have to set some environment variables. For the C-Shell,
type:</p>
<pre class="screen">
<code class="prompt">%</code> <strong class="userinput"><code>setenv CVSROOT anoncvs@anoncvs.NetBSD.org:/cvsroot</code></strong>
<code class="prompt">%</code> <strong class="userinput"><code>setenv CVS_RSH ssh</code></strong>
</pre>
<p>Or, the same for the bourne shell:</p>
<pre class="screen">
<code class="prompt">$</code> <strong class="userinput"><code>CVSROOT="anoncvs@anoncvs.NetBSD.org:/cvsroot"</code></strong>
<code class="prompt">$</code> <strong class="userinput"><code>CVS_RSH="ssh"</code></strong>
<code class="prompt">$</code> <strong class="userinput"><code>export CVSROOT CVS_RSH</code></strong>
</pre>
<p>By default, cvs doesn't do things like most people would
expect it to do, and this is unlikely to change. But there is a
way to convince cvs, by creating a file called
<code class="filename">.cvsrc</code> in your home directory and saving
the following lines to it. This file will save you lots of
headache and some bug reports, so we strongly recommend it. You
can find an explanation of this file in the CVS
documentation.</p>
<pre class="programlisting">
# recommended CVS configuration file from the pkgsrc guide
checkout -P
update -dP
release -d
diff -upN
cvs -q -z3
rdiff -u
</pre>
<p>Then, you change to the directory where you want to have
your copy of pkgsrc. In most cases this is
<code class="filename">/usr</code>. In that directory you run the
checkout command, which is <span class="command"><strong>cvs -q checkout -P
pkgsrc</strong></span> for the current branch and <span class="command"><strong>cvs -q
checkout -rpkgsrc-2007Q1 -P pkgsrc</strong></span> for the stable
branch. This command will create a directory called
<code class="filename">pkgsrc</code> with all the pkgsrc files in
it.</p>

<a name="uptodate"></a>2.2. Keeping pkgsrc up-to-date</h2></div></div></div>
<p>The preferred way to keep pkgsrc up-to-date is via CVS
(which also works if you have first installed it via a tar
file). It saves bandwidth and hard disk activity, compared to
downloading the tar file again.</p>
<div class="sect2" lang="en">

<div class="warning" style="margin-left: 0.5in; margin-right: 0.5in;">
<h3 class="title">Warning</h3>
<p>When updating from a tar file, you first need to
completely remove the old pkgsrc directory. Otherwise those
files that have been removed from pkgsrc in the mean time will
not be removed on your local disk, resulting in inconsistencies.
When removing the old files, any changes that you have done to
the pkgsrc files will be lost after updating. Therefore updating
via CVS is strongly recommended.</p>
</div>
<p>Note that by default the distfiles and the binary packages
are saved in the pkgsrc tree, so don't forget to rescue them
before updating. You can also configure pkgsrc to use other than
the default directories by setting the
<code class="varname">DISTDIR</code> and <code class="varname">PACKAGES</code>
variables. See <a class="xref" href="#configuring" title="Chapter 5. Configuring pkgsrc">Chapter 5, <i>Configuring pkgsrc</i></a> for the details.</p>
<p>To update pkgsrc from a tar file, download the tar file as
explained above. Then, make sure that you have not made any
changes to the files in the pkgsrc directory. Remove the pkgsrc
directory and extract the new tar file. Done.</p>

<p>When updating pkgsrc, the CVS program keeps track of the
branch you selected. But if you, for whatever reason, want to
switch from the stable branch to the current one, you can do it
by adding the option “<span class="quote">-A</span>” after the
“<span class="quote">update</span>” keyword. To switch from the current branch
back to the stable branch, add the
“<span class="quote">-rpkgsrc-2007Q1</span>” option.</p>

<p>When you update pkgsrc, the CVS program will only touch
those files that are registered in the CVS repository. That
means that any packages that you created on your own will stay
unmodified. If you change files that are managed by CVS, later
updates will try to merge your changes with those that have been
done by others. See the CVS manual, chapter
“<span class="quote">update</span>” for details.</p>

<div class="titlepage"><div><div><h3 class="title">
<a name="darwin"></a>3.3.1. Darwin (Mac OS X)</h3></div></div></div>
<p>Darwin 5.x and up are supported. There are two methods of using
pkgsrc on Mac OS X, by using a <a class="link" href="#platform.osx-image" title="3.3.1.1. Using a disk image">disk
image</a>, or a <a class="link" href="#platform.osx-part" title="3.3.1.2. Using a UFS or HFSX partition">UFS or HFSX
partition</a>.</p>
<p>Before you start, you will need to download and install the Mac OS X Developer
Tools from Apple's Developer Connection. See <a class="ulink" href="http://developer.apple.com/macosx/" target="_top">http://developer.apple.com/macosx/</a>
for details. Also, make sure you install X11 for Mac OS X and the X11 SDK
from <a class="ulink" href="http://www.apple.com/macosx/x11/download/" target="_top">http://www.apple.com/macosx/x11/download/</a>
if you intend to build packages that use the X11 Window System.</p>
<p>If you already have a UFS or HFSX partition, or have a spare partition
that you can format as UFS or HFSX, it is recommended to use that instead of
the disk image. It'll be somewhat faster and will mount automatically
at boot time, where you must manually mount a disk image.</p>
<div class="note" style="margin-left: 0.5in; margin-right: 0.5in;">
<h3 class="title">Note</h3>
<p>You cannot use an ordinary HFS+ file system for pkgsrc, because pkgsrc currently
requires the file system to be case-sensitive. You can, however, use a case-sensitive HFS+ (aka HFSX) file system as found in Darwin 7.0 and newer.</p>
</div>
<div class="sect3" lang="en">
<div class="titlepage"><div><div><h4 class="title">
<a name="platform.osx-image"></a>3.3.1.1. Using a disk image</h4></div></div></div>
<p>Create the disk image:</p>
<pre class="screen"><code class="prompt">#</code> <strong class="userinput"><code>cd pkgsrc/bootstrap</code></strong>
<code class="prompt">#</code> <strong class="userinput"><code>./darwindiskimage create ~/Documents/NetBSD 1024</code></strong> # megabytes - season to taste
<code class="prompt">#</code> <strong class="userinput"><code>./darwindiskimage mount ~/Documents/NetBSD</code></strong>
<code class="prompt">#</code> <strong class="userinput"><code>sudo chown `id -u`:`id -g` /Volumes/NetBSD</code></strong></pre>
<div class="note" style="margin-left: 0.5in; margin-right: 0.5in;">
<h3 class="title">Note</h3>
<p>darwindiskimage will mount the filesystem nosuid, which will cause problems for packages that depend on setgid. In the case of UFS, it will also mount the filesystem asynchronous, which is somewhat dangerous according to the mount(8) man page. In the case of HFSX, it will disable journaling.</p>
</div>
<p>Allow suid:</p>
<pre class="screen"><code class="prompt">#</code> <strong class="userinput"><code>sudo mount -u -o suid /Volumes/NetBSD</code></strong></pre>
<p>Changing the build directory:</p>
<p>After bootstrapping you need to change the default package build directory to somewhere outside the disk image so it doesn't get filled up in the process of building packages. Add something like that to <code class="filename">mk.conf</code>.</p>
<pre class="programlisting">
WRKOBJDIR?= /tmp/pkgsrc # build here instead of in pkgsrc
</pre>

<div class="titlepage"><div><div><h4 class="title">
<a name="platform.osx-part"></a>3.3.1.2. Using a UFS or HFSX partition</h4></div></div></div>
<p>By default, <code class="filename">/usr</code> will be on your root file
system, normally HFS+. It is possible to use the default
<span class="emphasis"><em>prefix</em></span> of <code class="filename">/usr/pkg</code>
by symlinking <code class="filename">/usr/pkg</code> to a directory on a UFS
or HFSX file system. Obviously, another symlink is required if you want to
place the package database directory outside the
<span class="emphasis"><em>prefix</em></span>. e.g.</p>
<pre class="screen"><code class="prompt">#</code> <strong class="userinput"><code>./bootstrap --pkgdbdir /usr/pkg/pkgdb</code></strong></pre>
<p>If you created your partitions at the time of installing Mac OS X
and formatted the target partition as UFS or HFSX, it should automatically
mount on <code class="filename">/Volumes/<volume name></code> when the
machine boots. If you are (re)formatting a partition as UFS or HFSX, you need
to ensure that the partition map correctly reflects
“<span class="quote">Apple_UFS</span>” or “<span class="quote">Apple_HFSX</span>” and not “<span class="quote">Apple_HFS</span>”.</p>
<p>The problem is that none of the disk tools will let you touch a
disk that is booted from. You can unmount the partition, but even if
you newfs it, the partition type will be incorrect and the
automounter won't mount it. It can be mounted manually, but it won't
appear in Finder.</p>
<p>You'll need to boot off of the OS X Installation (User) CD. When
the Installation program starts, go up to the menu and select Disk
Utility. Now, you will be able to select the partition you want
to be UFS or HFSX, and Format it Apple UFS or HFSX. Quit the Disk Utility, quit the
installer which will reboot your machine. The new UFS or HFSX file system
will appear in Finder.</p>
<p>Be aware that the permissions on the new file system will be writable
by root only.</p>
<p>This note is as of 10.2 (Jaguar) and applies to earlier versions.
Hopefully Apple will fix Disk Utility in 10.3 (Panther).</p>

<a name="interix"></a>3.3.3. Interix</h3></div></div></div>
<p>Interix is a POSIX-compatible subsystem for the Windows NT kernel,
providing a Unix-like environment with a tighter kernel integration than
available with Cygwin. It is part of the Windows Services for Unix
package, available for free for any licensed copy of Windows 2000, XP
(not including XP Home), or 2003. SFU can be downloaded from <a class="ulink" href="http://www.microsoft.com/windows/sfu/" target="_top">http://www.microsoft.com/windows/sfu/</a>.</p>
<p>Services for Unix 3.5 has been tested. 3.0 or 3.1 may work, but
are not officially supported. (The main difference in 3.0/3.1 is lack
of pthreads, but other parts of libc may also be lacking.)</p>
<p>Services for Unix Applications (aka SUA) is an integrated component
of Windows Server 2003 R2 and Windows Vista. As of this writing, SUA's
Interix 5.x subsystem has not yet been tested with pkgsrc.</p>
<div class="sect3" lang="en">
<div class="titlepage"><div><div><h4 class="title">
<a name="platform.interix-sfu-install"></a>3.3.3.1. When installing Interix/SFU</h4></div></div></div>
<p>At an absolute minimum, the following packages must be installed from
the Windows Services for Unix 3.5 distribution in order to use pkgsrc:</p>
<div class="itemizedlist"><ul type="disc">
<li><p>Utilities -> Base Utilities</p></li>
<li><p>Interix GNU Components -> (all)</p></li>
<li><p>Remote Connectivity</p></li>
<li><p>Interix SDK</p></li>
</ul></div>
<p>When using pkgsrc on Interix, DO NOT install the Utilities subcomponent
"UNIX Perl". That is Perl 5.6 without shared module support, installed to
/usr/local, and will only cause confusion. Instead, install Perl 5.8 from
pkgsrc (or from a binary package).</p>
<p>The Remote Connectivity subcomponent "Windows Remote Shell Service" does
not need to be installed, but Remote Connectivity itself should be
installed in order to have a working inetd.</p>
<p>During installation you may be asked whether to enable setuid
behavior for Interix programs, and whether to make pathnames default to
case-sensitive. Setuid should be enabled, and case-sensitivity MUST be
enabled. (Without case-sensitivity, a large number of packages including
perl will not build.)</p>
<p>NOTE: Newer Windows service packs change the way binary execution
works (via the Data Execution Prevention feature). In order to use
pkgsrc and other gcc-compiled binaries reliably, a hotfix containing
POSIX.EXE, PSXDLL.DLL, PSXRUN.EXE, and PSXSS.EXE (899522 or newer)
must be installed. Hotfixes are available from Microsoft through a
support contract; however, a NetBSD developer has made most Interix
hotfixes available for personal use from <a class="ulink" href="http://www.duh.org/interix/hotfixes.php" target="_top">http://www.duh.org/interix/hotfixes.php</a>.</p>
<p>In addition to the hotfix noted above, it may be necessary to
disable Data Execution Prevention entirely to make Interix functional.
This may happen only with certain types of CPUs; the cause is not fully
understood at this time. If gcc or other applications still segfault
repeatedly after installing one of the hotfixes note above, the
following option can be added to the appropriate "boot.ini" line on the
Windows boot drive: /NoExecute=AlwaysOff
(WARNING, this will disable DEP completely, which may be a security
risk if applications are often run as a user in the Administrators
group!)</p>

<p>The package manager (either the pkgsrc "su" user, or the user
running "pkg_add") must be a member of the local Administrators
group. Such a user must also be used to run the bootstrap. This is
slightly relaxed from the normal pkgsrc requirement of "root".</p>
<p>The package manager should use a umask of 002. "make install" will
automatically complain if this is not the case. This ensures that
directories written in /var/db/pkg are Administrators-group writeable.</p>

use an older version of pkgsrc's pkg_* tools. Ideally, these should
NOT be used in conjunction with pkgsrc. If you choose to use them at
the same time as the pkgsrc packages, ensure that you use the proper
pkg_* tools for each type of binary package.</p>
<p>The TERM setting used for DOS-type console windows (including those
invoked by the csh and ksh startup shortcuts) is "interix". Most systems
don't have a termcap/terminfo entry for it, but the following .termcap
entry provides adequate emulation in most cases:</p>

<a name="platform.interix-limits"></a>3.3.3.4. Limitations of the Interix platform</h4></div></div></div>
<p>Though Interix suffices as a familiar and flexible substitute
for a full Unix-like platform, it has some drawbacks that should
be noted for those desiring to make the most of Interix.</p>
<div class="itemizedlist"><ul type="disc">
<li>
<p><span class="strong"><strong>X11:</strong></span></p>
<p>Interix comes with the standard set of X11R6 client libraries,
and can run X11 based applications, but it does
<span class="emphasis"><em>not</em></span> come with an X server. Some options are
<a class="ulink" href="http://www.starnet.com/products/xwin32/" target="_top">StarNet X-Win32</a>,
<a class="ulink" href="http://connectivity.hummingbird.com/products/nc/exceed/" target="_top">Hummingbird Exceed</a>
(available in a trimmed version for Interix from Interop Systems as the
<a class="ulink" href="http://www.interopsystems.com/InteropXserver.htm" target="_top">Interop X Server</a>),
and the free X11 server included with
<a class="ulink" href="http://x.cygwin.com/" target="_top">Cygwin</a>.</p>
</li>
<li>
<p><span class="strong"><strong>X11 acceleration:</strong></span></p>
<p>Because Interix runs in a completely different NT subsystem from
Win32 applications, it does not currently support various X11
protocol extensions for acceleration (such as MIT-SHM or DGA).
Most interactive applications to a local X server will run
reasonably fast, but full motion video and other graphics
intensive applications may require a faster-than-expected CPU.</p>
</li>
<li>
<p><span class="strong"><strong>Audio:</strong></span></p>
<p>Interix has no native support for audio output. For audio
support, pkgsrc uses the <span class="command"><strong>esound</strong></span> client/server
audio system on Interix. Unlike on most platforms, the
<a href="ftp://ftp.NetBSD.org/pub/pkgsrc/current/pkgsrc/audio/esound/README.html" target="_top"><code class="filename">audio/esound</code></a> package does
<span class="emphasis"><em>not</em></span> contain the <span class="command"><strong>esd</strong></span>
server component. To output audio via an Interix host, the
<a href="ftp://ftp.NetBSD.org/pub/pkgsrc/current/pkgsrc/emulators/cygwin_esound/README.html" target="_top"><code class="filename">emulators/cygwin_esound</code></a> package
must also be installed.</p>
</li>
<li>
<p><span class="strong"><strong>CD/DVDs, USB, and SCSI:</strong></span></p>
<p>Direct device access is not currently supported in Interix, so it
is not currently possible to access CD/DVD drives, USB devices,
or SCSI devices through non-filesystem means. Among other things,
this makes it impossible to use Interix directly for CD/DVD
burning.</p>
</li>
<li>
<p><span class="strong"><strong>Tape drives:</strong></span></p>
<p>Due to the same limitations as for CD-ROMs and SCSI devices, tape
drives are also not directly accessible in Interix. However,
support is in work to make tape drive access possible by using
Cygwin as a bridge (similarly to audio bridged via Cygwin's
esound server).</p>

<p>It is not necessary, in general, to have a "root" user on the
Windows system; any member of the local Administrators group will
suffice. However, some packages currently assume that the user
named "root" is the privileged user. To accommodate these, you
may create such a user; make sure it is in the local group
Administrators (or your language equivalent).</p>
<p><span class="command"><strong>pkg_add</strong></span> creates directories of mode
0755, not 0775, in <code class="filename">$PKG_DBDIR</code>. For the
time being, install packages as the local Administrator (or

installing a package to work around the issue:</p>

<div class="titlepage"><div><div><h3 class="title">
<a name="irix"></a>3.3.4. IRIX</h3></div></div></div>
<p>You will need a working C compiler, either gcc or SGI's MIPS and MIPSpro
compiler (cc/c89). Please set the <code class="varname">CC</code> environment variable
according to your preference. If you do not have a license for the MIPSpro
compiler suite, you can download a gcc tardist file from <a class="ulink" href="http://freeware.sgi.com/" target="_top">http://freeware.sgi.com/</a>.</p>
<p>Please note that you will need IRIX 6.5.17 or higher, as this is the earliest
version of IRIX providing support for <a class="citerefentry" href="http://netbsd.gw.com/cgi-bin/man-cgi?if_indextoname+3+NetBSD-current"><span class="citerefentry"><span class="refentrytitle">if_indextoname</span>(3)</span></a>, <a class="citerefentry" href="http://netbsd.gw.com/cgi-bin/man-cgi?if_nametoindex+3+NetBSD-current"><span class="citerefentry"><span class="refentrytitle">if_nametoindex</span>(3)</span></a>,
etc.</p>
<p>At this point in time, pkgsrc only supports one ABI at a time. That is, you cannot
switch between the old 32-bit ABI, the new 32-bit ABI and the 64-bit ABI. If
you start out using "abi=n32", that's what all your packages will be built
with.</p>
<p>Therefore, please make sure that you have no conflicting
<code class="varname">CFLAGS</code> in your environment or the
<a class="link" href="#mk.conf"><code class="filename">mk.conf</code></a>. Particularly, make sure that you do not
try to link n32 object files with lib64 or vice versa. Check your
<code class="filename">/etc/compiler.defaults</code>!</p>
<p>If you have the actual pkgsrc tree mounted via NFS from a different host,
please make sure to set <code class="varname">WRKOBJDIR</code> to a local directory,
as it appears that IRIX linker occasionally runs into issues when trying to
link over a network-mounted file system.</p>
<p>The bootstrapping process should set all the right options for programs such
as imake(1), but you may want to set some options depending on your local
setup. Please see <code class="filename">pkgsrc/mk/defaults/mk.conf</code> and, of
course, your compiler's man pages for details.</p>
<p>If you are using SGI's MIPSPro compiler, please set
</p>
<pre class="programlisting">
PKGSRC_COMPILER= mipspro
</pre>
<p>
in <a class="link" href="#mk.conf"><code class="filename">mk.conf</code></a>. Otherwise, pkgsrc will assume you
are using gcc and may end up passing invalid flags to the compiler. Note that
bootstrap should create an appropriate <code class="filename">mk.conf.example</code> by
default.</p>
<p>If you have both the MIPSPro compiler chain installed as well as gcc,
but want to make sure that MIPSPro is used, please set your <code class="varname">PATH</code>
to <span class="emphasis"><em>not</em></span> include the location of gcc (often
<code class="filename">/usr/freeware/bin</code>), and (important) pass the
'--preserve-path' flag.</p>

<div class="sect2" lang="en">
<div class="titlepage"><div><div><h3 class="title">
<a name="linux"></a>3.3.5. Linux</h3></div></div></div>
<p>Some versions of Linux (for example Debian GNU/Linux) need
either libtermcap or libcurses (libncurses). Installing the
distributions libncurses-dev package (or equivalent) should fix
the problem.</p>
<p>pkgsrc supports both gcc (GNU Compiler Collection) and icc
(Intel C++ Compiler). gcc is the default. icc 8.0 and 8.1 on
i386 have been tested.</p>
<p>To bootstrap using icc, assuming the default icc installation
directory:</p>
<pre class="programlisting">
env CC=/opt/intel_cc_80/bin/icc LDFLAGS=-static-libcxa \
ac_cv___attribute__=yes ./bootstrap
</pre>
<div class="note" style="margin-left: 0.5in; margin-right: 0.5in;">
<h3 class="title">Note</h3>
<p>icc 8.1 needs the `-i-static' argument instead of -static-libcxa.</p>
</div>
<p>icc supports __attribute__, but the GNU configure test uses a nested
function, which icc does not support. #undef'ing __attribute__ has the
unfortunate side-effect of breaking many of the Linux header files, which
cannot be compiled properly without __attribute__. The test must be
overridden so that __attribute__ is assumed supported by the
compiler.</p>
<p>After bootstrapping, you should set <code class="varname">PKGSRC_COMPILER</code>
in <a class="link" href="#mk.conf"><code class="filename">mk.conf</code></a>:</p>
<pre class="programlisting">
PKGSRC_COMPILER= icc
</pre>
<p>The default installation directory for icc is
<code class="filename">/opt/intel_cc_80</code>, which
is also the pkgsrc default. If you have installed it into a different
directory, set <code class="varname">ICCBASE</code> in
<a class="link" href="#mk.conf"><code class="filename">mk.conf</code></a>:</p>
<pre class="programlisting">
ICCBASE= /opt/icc
</pre>
<p>pkgsrc uses the static linking method of the runtime libraries
provided by icc, so binaries can be run on other systems which do not
have the shared libraries installed.</p>
<p>Libtool, however, extracts a list of libraries from the
<a class="citerefentry" href="http://netbsd.gw.com/cgi-bin/man-cgi?ld+1+NetBSD-current"><span class="citerefentry"><span class="refentrytitle">ld</span>(1)</span></a> command run when linking a C++ shared library and
records it, throwing away the -Bstatic and -Bdynamic options
interspersed between the libraries. This means that
libtool-linked C++ shared libraries will have a runtime
dependency on the icc libraries until this is fixed in
libtool.</p>

<p>OpenBSD 3.0 and 3.2 are tested and supported.</p>
<p>Care should be taken so that the tools that this kit installs do not conflict
with the OpenBSD userland tools. There are several steps:</p>
<div class="orderedlist"><ol type="1">
<li><p>OpenBSD stores its ports pkg database in
<code class="filename">/var/db/pkg</code>. It is therefore
recommended that you choose a different location (e.g.

<li>
<p>If you do not intend to use the OpenBSD ports tools, it's probably a
good idea to move them out of the way to avoid confusion, e.g.</p>
<pre class="screen">

<p>An example <a class="link" href="#mk.conf"><code class="filename">mk.conf</code></a> file will be placed in

<p>Basically, there are two ways of using pkgsrc. The first
is to only install the package tools and to use binary packages
that someone else has prepared. This is the “<span class="quote">pkg</span>”
in pkgsrc. The second way is to install the “<span class="quote">src</span>”
of pkgsrc, too. Then you are able to build your own packages,
and you can still use binary packages from someone else.</p>
<div class="sect1" lang="en">
<div class="titlepage"><div><div><h2 class="title" style="clear: both">
<a name="using-pkg"></a>4.1. Using binary packages</h2></div></div></div>
<p>On the <a class="ulink" href="ftp://ftp.NetBSD.org/" target="_top">ftp.NetBSD.org</a>
server and its mirrors, there are collections of binary packages,
ready to be installed. These binary packages have been built using the
default settings for the directories, that is:</p>
<div class="itemizedlist"><ul type="disc">
<li><p><code class="filename">/usr/pkg</code> for <code class="varname">LOCALBASE</code>, where most of the files are installed,</p></li>
<li><p><code class="filename">/usr/pkg/etc</code> for configuration files,</p></li>
<li><p><code class="filename">/var</code> for <code class="varname">VARBASE</code>, where those files are installed that may change after installation.</p></li>
</ul></div>
<p>If you cannot use these directories for whatever reasons (maybe
because you're not root), you cannot use these binary packages, but
have to build the packages yourself, which is explained in <a class="xref" href="#bootstrapping-pkgsrc" title="3.2. Bootstrapping pkgsrc">Section 3.2, “Bootstrapping pkgsrc”</a>.</p>
<div class="sect2" lang="en">
<div class="titlepage"><div><div><h3 class="title">
<a name="finding-binary-packages"></a>4.1.1. Finding binary packages</h3></div></div></div>
<p>To install binary packages, you first need to know from where
to get them. The first place where you should look is on the main
pkgsrc FTP server in the directory <a class="ulink" href="ftp://ftp.NetBSD.org/pub/pkgsrc/packages/" target="_top"><code class="filename">/pub/pkgsrc/packages</code></a>.</p>
<p>This directory contains binary packages for multiple
platforms. First, select your operating system. (Ignore the
directories with version numbers attached to it, they just exist for
legacy reasons.) Then, select your hardware architecture, and in the
third step, the OS version and the “<span class="quote">version</span>” of pkgsrc.</p>
<p>In this directory, you often find a file called
<code class="filename">bootstrap.tar.gz</code> which contains the package
management tools. If the file is missing, it is likely that your
operating system already provides those tools. Download the file and
extract it in the <code class="filename">/</code> directory. It will create
the directories <code class="filename">/usr/pkg</code> (containing the tools
for managing binary packages) and <code class="filename">/var/db/pkg</code>
(the database of installed packages).</p>
</div>
<div class="sect2" lang="en">
<div class="titlepage"><div><div><h3 class="title">
<a name="installing-binary-packages"></a>4.1.2. Installing binary packages</h3></div></div></div>
<p>In the directory from the last section, there is a
subdirectory called <code class="filename">All</code>, which contains all the
binary packages that are available for the platform, excluding those
that may not be distributed via FTP or CDROM (depending on which
medium you are using), and the ones that have vulnerabilities and
therefore are considered insecure to install without thinking
before.</p>
<p>To install packages directly from an FTP or HTTP server, run
the following commands in a Bourne-compatible shell (be sure to
<span class="command"><strong>su</strong></span> to root first):</p>
<pre class="screen">
<code class="prompt">#</code> <strong class="userinput"><code>PATH="/usr/pkg/sbin:$PATH"</code></strong>
<code class="prompt">#</code> <strong class="userinput"><code>PKG_PATH="ftp://ftp.NetBSD.org/pub/pkgsrc/packages/<em class="replaceable"><code>OPSYS</code></em>/<em class="replaceable"><code>ARCH</code></em>/<em class="replaceable"><code>VERSIONS</code></em>/All"</code></strong>
<code class="prompt">#</code> <strong class="userinput"><code>export PATH PKG_PATH</code></strong>
</pre>
<p>Instead of URLs, you can also use local paths, for example if
you are installing from a set of CDROMs, DVDs or an NFS-mounted
repository. If you want to install packages from multiple sources,
you can separate them by a semicolon in
<code class="varname">PKG_PATH</code>.</p>
<p>After these preparations, installing a package is very
easy:</p>
<pre class="screen">
<code class="prompt">#</code> <strong class="userinput"><code>pkg_add openoffice2</code></strong>
<code class="prompt">#</code> <strong class="userinput"><code>pkg_add kde-3.5.7</code></strong>
<code class="prompt">#</code> <strong class="userinput"><code>pkg_add ap2-php5-*</code></strong>
</pre>
<p>Note that any prerequisite packages needed to run the
package in question will be installed, too, assuming they are
present where you install from.</p>
<p>As mentioned above, packages for which vulnerabilities get
known are not stored in the <code class="filename">All</code> subdirectory.
They don't get deleted since that could be very frustrating if many
other packages depend on it. Instead, they are moved to the
<code class="filename">vulnerable</code> subdirectory. So you may need to add
this directory to the <code class="varname">PKG_PATH</code> variable.
However, you should run <a href="ftp://ftp.NetBSD.org/pub/pkgsrc/current/pkgsrc/security/audit-packages/README.html" target="_top"><code class="filename">security/audit-packages</code></a> regularly, especially
after installing new packages, and verify that the vulnerabilities
are acceptable for your configuration.</p>
<p>After you've installed packages, be sure to have
<code class="filename">/usr/pkg/bin</code> and <code class="filename">/usr/pkg/sbin</code> in your
<code class="varname">PATH</code> so you can actually start the just
installed program.</p>
</div>
<div class="sect2" lang="en">
<div class="titlepage"><div><div><h3 class="title">
<a name="using.pkg_delete"></a>4.1.3. Deinstalling packages</h3></div></div></div>
<p>To deinstall a package, it does not matter whether it was
installed from source code or from a binary package. The
<span class="command"><strong>pkg_delete</strong></span> command does not know it anyway.
To delete a package, you can just run <span class="command"><strong>pkg_delete
<em class="replaceable"><code>package-name</code></em></strong></span>. The package
name can be given with or without version number. Wildcards can
also be used to deinstall a set of packages, for example
<code class="literal">*emacs*</code>. Be sure to include them in quotes,
so that the shell does not expand them before
<code class="literal">pkg_delete</code> sees them.</p>
<p>The <code class="option">-r</code> option is very powerful: it
removes all the packages that require the package in question
and then removes the package itself. For example:
</p>
<pre class="screen">
<code class="prompt">#</code> <strong class="userinput"><code>pkg_delete -r jpeg</code></strong>
</pre>
<p>
will remove jpeg and all the packages that used it; this allows
upgrading the jpeg package.</p>

<p>
The NetBSD Security-Officer and Packages Groups maintain a list of
known security vulnerabilities to packages which are (or have been)
included in pkgsrc. The list is available from the NetBSD
FTP site at <a class="ulink" href="ftp://ftp.NetBSD.org/pub/pkgsrc/distfiles/vulnerabilities" target="_top">ftp://ftp.NetBSD.org/pub/pkgsrc/distfiles/vulnerabilities</a>.
</p>
<p>
Through <a href="ftp://ftp.NetBSD.org/pub/pkgsrc/current/pkgsrc/security/audit-packages/README.html" target="_top"><code class="filename">security/audit-packages</code></a>,
this list can be downloaded
automatically, and a security audit of all packages installed on a system
can take place.
</p>
<p>
There are two components to
<a href="ftp://ftp.NetBSD.org/pub/pkgsrc/current/pkgsrc/security/audit-packages/README.html" target="_top"><code class="filename">security/audit-packages</code></a>. The first
component, “<span class="quote">download-vulnerability-list</span>”, is for downloading
the list of vulnerabilities from the NetBSD FTP site. The second
component, “<span class="quote">audit-packages</span>”, checks to see if any of your
installed packages are vulnerable. If a package is vulnerable, you
will see output similar to the following:
</p>
<pre class="screen">Package samba-2.0.9 has a local-root-shell vulnerability, see
http://www.samba.org/samba/whatsnew/macroexploit.html</pre>
<p>
One can set up <a href="ftp://ftp.NetBSD.org/pub/pkgsrc/current/pkgsrc/security/audit-packages/README.html" target="_top"><code class="filename">security/audit-packages</code></a> to download the
<a class="ulink" href="ftp://ftp.NetBSD.org/pub/pkgsrc/distfiles/vulnerabilities" target="_top">vulnerabilities</a>
file daily, and include a package audit in the daily security script.

<p>After obtaining pkgsrc, the <code class="filename">pkgsrc</code>
directory now contains a set of packages, organized into
categories. You can browse the online index of packages, or run
<span class="command"><strong>make readme</strong></span> from the <code class="filename">pkgsrc</code>
directory to build local <code class="filename">README.html</code> files for
all packages, viewable with any web browser such as <a href="ftp://ftp.NetBSD.org/pub/pkgsrc/current/pkgsrc/www/lynx/README.html" target="_top"><code class="filename">www/lynx</code></a> or <a href="ftp://ftp.NetBSD.org/pub/pkgsrc/current/pkgsrc/www/firefox/README.html" target="_top"><code class="filename">www/firefox</code></a>.</p>
<p>The default <span class="emphasis"><em>prefix</em></span> for installed packages
is <code class="filename">/usr/pkg</code>. If you wish to change this, you
should do so by setting <code class="varname">LOCALBASE</code> in
<a class="link" href="#mk.conf"><code class="filename">mk.conf</code></a>. You should not try to use multiple
different <code class="varname">LOCALBASE</code> definitions on the same
system (inside a chroot is an exception). </p>
<p>The rest of this chapter assumes that the package is already
in pkgsrc. If it is not, see <a class="xref" href="#developers-guide" title="Part II. The pkgsrc developer's guide">Part II, “The pkgsrc developer's guide”</a> for
instructions how to create your own packages.</p>

<div class="titlepage"><div><div><h3 class="title">
<a name="requirements"></a>4.2.1. Requirements</h3></div></div></div>
<p>To build packages from source, you need a working C
compiler. On NetBSD, you need to install the
“<span class="quote">comp</span>” and the “<span class="quote">text</span>” distribution
sets. If you want to build X11-related packages, the
“<span class="quote">xbase</span>” and “<span class="quote">xcomp</span>” distribution
sets are required, too.</p>
</div>
<div class="sect2" lang="en">
<div class="titlepage"><div><div><h3 class="title">
<a name="fetching-distfiles"></a>4.2.2. Fetching distfiles</h3></div></div></div>
<p>The first step for building a package is downloading the
distfiles (i.e. the unmodified source). If they have not yet been
downloaded, pkgsrc will fetch them automatically.</p>
<p>If you have all files that you need in the
<code class="filename">distfiles</code> directory,
you don't need to connect. If the distfiles are on CD-ROM, you can
mount the CD-ROM on <code class="filename">/cdrom</code> and add:
</p>
<pre class="screen">DISTDIR=/cdrom/pkgsrc/distfiles</pre>
<p>
to your <a class="link" href="#mk.conf"><code class="filename">mk.conf</code></a>.</p>
<p>By default a list of distribution sites will be randomly
intermixed to prevent huge load on servers which holding popular
packages (for example, SourceForge.net mirrors). Thus, every
time when you need to fetch yet another distfile all the mirrors
will be tried in new (random) order. You can turn this feature
off by setting <code class="varname">MASTER_SORT_RANDOM=NO</code> (for
<code class="varname">PKG_DEVELOPER</code>s it's already disabled).</p>
<p>You can overwrite some of the major distribution sites to
fit to sites that are close to your own. By setting one or two
variables you can modify the order in which the master sites are
accessed. <code class="varname">MASTER_SORT</code> contains a whitespace
delimited list of domain suffixes.
<code class="varname">MASTER_SORT_REGEX</code> is even more flexible, it
contains a whitespace delimited list of regular expressions. It
has higher priority than <code class="varname">MASTER_SORT</code>. Have a
look at <code class="filename">pkgsrc/mk/defaults/mk.conf</code> to find
some examples. This may save some of your bandwidth and
time.</p>
<p>You can change these settings either in your shell's environment, or,
if you want to keep the settings, by editing the
<a class="link" href="#mk.conf"><code class="filename">mk.conf</code></a> file,
and adding the definitions there.</p>
<p>
If a package depends on many other packages (such as
<a href="ftp://ftp.NetBSD.org/pub/pkgsrc/current/pkgsrc/meta-pkgs/kde3/README.html" target="_top"><code class="filename">meta-pkgs/kde3</code></a>), the build process may
alternate between periods of
downloading source, and compiling. To ensure you have all the source
downloaded initially you can run the command:
</p>
<pre class="screen"><code class="prompt">%</code> <strong class="userinput"><code>make fetch-list | sh</code></strong></pre>
<p>
which will output and run a set of shell commands to fetch the
necessary files into the <code class="filename">distfiles</code> directory. You can
also choose to download the files manually.

<a name="how-to-build-and-install"></a>4.2.3. How to build and install</h3></div></div></div>
<p>
Once the software has downloaded, any patches will be applied, then it
will be compiled for you. This may take some time depending on your
computer, and how many other packages the software depends on and their
compile time.
</p>
<div class="note" style="margin-left: 0.5in; margin-right: 0.5in;">
<h3 class="title">Note</h3>
<p>If using bootstrap or pkgsrc on a non-NetBSD system,
use the pkgsrc <span class="command"><strong>bmake</strong></span> command instead of
“<span class="quote">make</span>” in the examples in this guide.</p>
</div>
<p>For example, type</p>
<pre class="screen">
<code class="prompt">%</code> <strong class="userinput"><code>cd misc/figlet</code></strong>
<code class="prompt">%</code> <strong class="userinput"><code>make</code></strong>
</pre>
<p>at the shell prompt to build the various components of the
package.</p>
<p>The next stage is to actually install the newly compiled
program onto your system. Do this by entering:
</p>
<pre class="screen">
<code class="prompt">%</code> <strong class="userinput"><code>make install</code></strong>
</pre>
<p>
while you are still in the directory for whatever package you
are installing.</p>
<p>Installing the package on your system may require you to
be root. However, pkgsrc has a
<span class="emphasis"><em>just-in-time-su</em></span> feature, which allows you
to only become root for the actual installation step.</p>
<p>That's it, the software should now be installed and setup for use.
You can now enter:
</p>
<pre class="screen">
<code class="prompt">%</code> <strong class="userinput"><code>make clean</code></strong>
</pre>
<p>
to remove the compiled files in the work directory, as you shouldn't need
them any more. If other packages were also added to your system
(dependencies) to allow your program to compile, you can tidy these up
also with the command:</p>
<pre class="screen">
<code class="prompt">%</code> <strong class="userinput"><code>make clean-depends</code></strong>
</pre>
<p>Taking the figlet utility as an example, we can install it on our
system by building as shown in <a class="xref" href="#logs" title="Appendix B. Build logs">Appendix B, <i>Build logs</i></a>.</p>
<p>The program is installed under the default root of the
packages tree - <code class="filename">/usr/pkg</code>. Should this not
conform to your tastes, set the <code class="varname">LOCALBASE</code>
variable in your environment, and it will use that value as the
root of your packages tree. So, to use
<code class="filename">/usr/local</code>, set
<code class="varname">LOCALBASE=/usr/local</code> in your environment.
Please note that you should use a directory which is dedicated to
packages and not shared with other programs (i.e., do not try and
use <code class="varname">LOCALBASE=/usr</code>). Also, you should not try
to add any of your own files or directories (such as
<code class="filename">src/</code>, <code class="filename">obj/</code>, or
<code class="filename">pkgsrc/</code>) below the
<code class="varname">LOCALBASE</code> tree. This is to prevent possible
conflicts between programs and other files installed by the
package system and whatever else may have been installed
there.</p>
<p>Some packages look in <a class="link" href="#mk.conf"><code class="filename">mk.conf</code></a> to
alter some configuration options at build time. Have a look at
<code class="filename">pkgsrc/mk/defaults/mk.conf</code> to get an overview
of what will be set there by default. Environment variables such
as <code class="varname">LOCALBASE</code> can be set in
<a class="link" href="#mk.conf"><code class="filename">mk.conf</code></a> to save having to remember to
set them each time you want to use pkgsrc.</p>
<p>Occasionally, people want to “<span class="quote">look under the
covers</span>” to see what is going on when a package is building
or being installed. This may be for debugging purposes, or out of
simple curiosity. A number of utility values have been added to
help with this.</p>
<div class="orderedlist"><ol type="1">
<li>
<p>If you invoke the <a class="citerefentry" href="http://netbsd.gw.com/cgi-bin/man-cgi?make+1+NetBSD-current"><span class="citerefentry"><span class="refentrytitle">make</span>(1)</span></a> command with
<code class="varname">PKG_DEBUG_LEVEL=2</code>, then a huge amount of
information will be displayed. For example,</p>
<pre class="screen"><strong class="userinput"><code>make patch PKG_DEBUG_LEVEL=2</code></strong></pre>
<p>will show all the commands that are invoked, up to and
including the “<span class="quote">patch</span>” stage.</p>
</li>
<li>
<p>If you want to know the value of a certain <a class="citerefentry" href="http://netbsd.gw.com/cgi-bin/man-cgi?make+1+NetBSD-current"><span class="citerefentry"><span class="refentrytitle">make</span>(1)</span></a>
definition, then the <code class="varname">VARNAME</code> definition
should be used, in conjunction with the show-var
target. e.g. to show the expansion of the <a class="citerefentry" href="http://netbsd.gw.com/cgi-bin/man-cgi?make+1+NetBSD-current"><span class="citerefentry"><span class="refentrytitle">make</span>(1)</span></a>
variable <code class="varname">LOCALBASE</code>:</p>
<pre class="screen">
<code class="prompt">%</code> <strong class="userinput"><code>make show-var VARNAME=LOCALBASE</code></strong>
/usr/pkg
<code class="prompt">%</code>
</pre>
</li>
</ol></div>
<p>If you want to install a binary package that you've either
created yourself (see next section), that you put into
pkgsrc/packages manually or that is located on a remote FTP
server, you can use the "bin-install" target. This target will
install a binary package - if available - via <a class="citerefentry" href="http://netbsd.gw.com/cgi-bin/man-cgi?pkg_add+1+NetBSD-current"><span class="citerefentry"><span class="refentrytitle">pkg_add</span>(1)</span></a>,
else do a <span class="command"><strong>make package</strong></span>. The list of remote FTP
sites searched is kept in the variable
<code class="varname">BINPKG_SITES</code>, which defaults to
ftp.NetBSD.org. Any flags that should be added to <a class="citerefentry" href="http://netbsd.gw.com/cgi-bin/man-cgi?pkg_add+1+NetBSD-current"><span class="citerefentry"><span class="refentrytitle">pkg_add</span>(1)</span></a>
can be put into <code class="varname">BIN_INSTALL_FLAGS</code>. See
<code class="filename">pkgsrc/mk/defaults/mk.conf</code> for more
details.</p>
<p>A final word of warning: If you set up a system that has a
non-standard setting for <code class="varname">LOCALBASE</code>, be sure to
set that before any packages are installed, as you cannot use
several directories for the same purpose. Doing so will result in
pkgsrc not being able to properly detect your installed packages,
and fail miserably. Note also that precompiled binary packages are
usually built with the default <code class="varname">LOCALBASE</code> of
<code class="filename">/usr/pkg</code>, and that you should
<span class="emphasis"><em>not</em></span> install any if you use a non-standard
<code class="varname">LOCALBASE</code>.</p>

<a name="mk.conf"></a><p>The whole pkgsrc system is configured in a single file, usually
called <code class="filename">mk.conf</code>. In which directory pkgsrc looks for
that file depends on the installation. On NetBSD, when you use
<a class="citerefentry" href="http://netbsd.gw.com/cgi-bin/man-cgi?make+1+NetBSD-current"><span class="citerefentry"><span class="refentrytitle">make</span>(1)</span></a> from the base system, it is in the directory
<code class="filename">/etc/</code>. In all other cases the default location is
<code class="literal">${PREFIX}/etc/</code>, depending on where you told the
bootstrap program to install the binary packages.</p>
<p>During the bootstrap, an example configuration file is created. To
use that, you have to create the directory
<code class="filename">${PREFIX}/etc</code> and copy the example file
there.</p>
<p>The format of the configuration file is that of the usual
BSD-style <code class="filename">Makefile</code>s. The whole pkgsrc configuration
is done by setting variables in this file. Note that you can define all
kinds of variables, and no special error checking (for example for
spelling mistakes) takes place, so you have to try it out to see if it
works.</p>

<p>A growing number of packages support installation into a

to be built, before the actual filesystem is touched. DESTDIR
support exists in two variations:</p>
<div class="itemizedlist"><ul type="disc">

</ul></div>
<p>To use the DESTDIR support, set either
<code class="varname">USE_DESTDIR=yes</code> to use the basic support for
packages that offer it or <code class="varname">USE_DESTDIR=full</code> to
get the full support with fallback to basic
support. <code class="varname">USE_DESTDIR=full</code> needs <a href="ftp://ftp.NetBSD.org/pub/pkgsrc/current/pkgsrc/pkgtools/pkg_install/README.html" target="_top"><code class="filename">pkgtools/pkg_install</code></a> version 20070802 (or
newer). It might become the default DESTDIR support later.</p>
<p>DESTDIR support changes the behaviour of various targets
slightly. To install a package after building it, use
<code class="literal">package-install</code>. <code class="literal">package</code> and
<code class="literal">install</code> don't do that any
longer. <code class="literal">package-install</code> can be used as
<code class="varname">DEPENDS_TARGET</code>. <code class="literal">bin-install</code>
will ask for the root password to install the package and fail,
<code class="literal">package-install</code> will ask again.</p>
<p>With basic DESTDIR support, <strong class="userinput"><code>make

overridden by setting the following variables in /etc/mk.conf:</p>
<div class="variablelist"><dl>
<dt><span class="term"><code class="varname">PKGSRC_COMPILER</code>:</span></dt>
<dd>
<p>This is a list of values specifying the chain of
compilers to invoke when building packages. Valid values
are:</p>
<div class="itemizedlist"><ul type="disc">
<li><p><code class="varname">distcc</code>:

<li><p><code class="varname">sunpro</code>:
Sun Microsystems, Inc. WorkShip/Forte/Sun ONE Studio</p></li>
</ul></div>
<p>The default is
“<span class="quote"><code class="varname">gcc</code></span>”. You can use
<code class="varname">ccache</code> and/or
<code class="varname">distcc</code> with an appropriate
<code class="varname">PKGSRC_COMPILER</code> setting,
e.g. “<span class="quote"><code class="varname">ccache gcc</code></span>”. This
variable should always be terminated with a value for
a real compiler. Note that only one real compiler
should be listed (e.g. “<span class="quote"><code class="varname">sunpro gcc</code></span>”
is not allowed).</p>
</dd>
<dt><span class="term"><code class="varname">GCC_REQD</code>:</span></dt>
<dd><p>This specifies the minimum version of GCC to use

<p>Some packages have build time options, usually to select
between different dependencies, enable optional support for big
dependencies or enable experimental features.</p>
<p>To see which options, if any, a package supports, and which
options are mutually exclusive, run <span class="command"><strong>make
show-options</strong></span>, for example:</p>
<pre class="programlisting">
The following options are supported by this package:
ssl Enable SSL support.
Exactly one of the following gecko options is required:
firefox Use firefox as gecko rendering engine.
mozilla Use mozilla as gecko rendering engine.
At most one of the following database options may be selected:
mysql Enable support for MySQL database.
pgsql Enable support for PostgreSQL database.
These options are enabled by default: firefox
These options are currently enabled: mozilla ssl
</pre>
<p>The following variables can be defined in
<a class="link" href="#mk.conf"><code class="filename">mk.conf</code></a> to select which options to
enable for a package: <code class="varname">PKG_DEFAULT_OPTIONS</code>,
which can be used to select or disable options for all packages
that support them, and
<code class="varname">PKG_OPTIONS.<em class="replaceable"><code>pkgbase</code></em></code>,
which can be used to select or disable options specifically for
package <em class="replaceable"><code>pkgbase</code></em>. Options listed in
these variables are selected, options preceded by “<span class="quote">-</span>”
are disabled. A few examples:</p>
<pre class="screen">

PKG_DEFAULT_OPTIONS= -arts -dvdread -esound
PKG_OPTIONS.kdebase= debug -sasl
PKG_OPTIONS.apache= suexec </pre>
<p>The following settings are consulted in the order given, and
the last setting that selects or disables an option is
used:</p>
<div class="orderedlist"><ol type="1">

<li><p><code class="varname">PKG_OPTIONS.<em class="replaceable"><code>pkgbase</code></em></code></p></li>
</ol></div>
<p>For groups of mutually exclusive options, the last option
selected is used, all others are automatically disabled. If an
option of the group is explicitly disabled, the previously
selected option, if any, is used. It is an error if no option
from a required group of options is selected, and building the
package will fail.</p>
<p>Before the options framework was introduced, build options
were selected by setting a variable (often named
<code class="varname">USE_<em class="replaceable"><code>FOO</code></em></code>) in
<a class="link" href="#mk.conf"><code class="filename">mk.conf</code></a> for each option. To ease
transition to the options framework for the user, these legacy
variables are converted to the appropriate options setting
(<code class="varname">PKG_OPTIONS.<em class="replaceable"><code>pkgbase</code></em></code>)
automatically. A warning is issued to prompt the user to update
<a class="link" href="#mk.conf"><code class="filename">mk.conf</code></a> to use the options framework
directly. Support for the legacy variables will be removed

<p>Once you have built and installed a package, you can create
a <span class="emphasis"><em>binary package</em></span> which can be installed on
another system with <a class="citerefentry" href="http://netbsd.gw.com/cgi-bin/man-cgi?pkg_add+1+NetBSD-current"><span class="citerefentry"><span class="refentrytitle">pkg_add</span>(1)</span></a>. This saves having to build
the same package on a group of hosts and wasting CPU time. It also
provides a simple means for others to install your package, should
you distribute it.</p>
<p>To create a binary package, change into the appropriate
directory in pkgsrc, and run <span class="command"><strong>make
package</strong></span>:</p>
<pre class="screen">
<code class="prompt">#</code> <strong class="userinput"><code>cd misc/figlet</code></strong>
<code class="prompt">#</code> <strong class="userinput"><code>make package</code></strong>
</pre>
<p>This will build and install your package (if not already done),
and then build a binary package from what was installed. You can
then use the <span class="command"><strong>pkg_*</strong></span> tools to manipulate
it. Binary packages are created by default in
<code class="filename">/usr/pkgsrc/packages</code>, in the form of a
gzipped tar file. See <a class="xref" href="#logs.package" title="B.2. Packaging figlet">Section B.2, “Packaging figlet”</a> for a

<p>When you have multiple machines that should run the same packages,
it is wasted time if they all build their packages themselves from
source. There are two ways of getting a set of binary packages: The old
bulk build system, or the new (as of 2007) parallel bulk build (pbulk)
system. This chapter describes how to set them up so that the packages
are most likely to be usable later.</p>
<div class="sect1" lang="en">
<div class="titlepage"><div><div><h2 class="title" style="clear: both">
<a name="bulk.pre"></a>7.1. Think first, build later</h2></div></div></div>
<p>Since a bulk build takes several days or even weeks to finish, you
should think about the setup before you start everything. Pay attention
to at least the following points:</p>
<div class="itemizedlist"><ul type="disc">
<li>
<p>If you want to upload the binary packages to
ftp.NetBSD.org, make sure the setup complies to the requirements for binary
packages:</p>
<div class="itemizedlist"><ul type="circle">
<li><p>To end up on ftp.NetBSD.org, the packages must be built
by a NetBSD developer on a trusted machine (that is, where you and only
you have root access).</p></li>
<li><p>Packages on ftp.NetBSD.org should only be created from
the stable branches (like 2007Q1), so that users browsing the available
collections can see at a glance how old the packages
are.</p></li>
<li><p>The packages must be built as root, since some packages
require set-uid binaries at runtime, and creating those packages as
unprivileged user doesn't work well at the moment.</p></li>
</ul></div>
</li>
<li><p>Make sure that the bulk build cannot break anything in
your system. Most bulk builds run as root, so they should be run at least
in a chroot environment or something even more restrictive, depending on
what the operating system provides. There have been numerous cases where
certain packages tried to install files outside the
<code class="filename">LOCALBASE</code> or wanted to edit some files in
<code class="filename">/etc</code>. Furthermore, the bulk builds install and
deinstall packages in <code class="filename">/usr/pkg</code> (or whatever
<code class="filename">LOCALBASE</code> is) during their operation, so be sure
that you don't need any package during the build.</p></li>
</ul></div>

<div class="titlepage"><div><div><h2 class="title" style="clear: both">
<a name="bulk.req"></a>7.2. Requirements of a bulk build</h2></div></div></div>
<p>A complete bulk build requires lots of disk space. Some of the
disk space can be read-only, some other must be writable. Some can be on
remote filesystems (such as NFS) and some should be local. Some can be
temporary filesystems, others must survive a sudden reboot.</p>
<div class="itemizedlist"><ul type="disc">
<li><p>10 GB for the distfiles (read-write, remote, temporary)</p></li>

<p>The <code class="filename">build.conf</code> file is the main
configuration file for bulk builds. You can configure how your
copy of pkgsrc is kept up to date, how the distfiles are
downloaded, how the packages are built and how the report is
generated. You can find an annotated example file in
<code class="filename">pkgsrc/mk/bulk/build.conf-example</code>. To use
it, copy <code class="filename">build.conf-example</code> to
<code class="filename">build.conf</code> and edit it, following the

<p>You may want to set variables in <a class="link" href="#mk.conf"><code class="filename">mk.conf</code></a>.
Look at <code class="filename">pkgsrc/mk/defaults/mk.conf</code> for
details of the default settings. You will want to ensure that
<code class="varname">ACCEPTABLE_LICENSES</code> meet your local policy.
As used in this example, <code class="varname">_ACCEPTABLE=yes</code>
completely bypasses the license check.</p>
<pre class="programlisting">

<p>Some options that are especially useful for bulk builds
can be found at the top lines of the file
<code class="filename">mk/bulk/bsd.bulk-pkg.mk</code>. The most useful
options of these are briefly described here.</p>
<div class="itemizedlist"><ul type="disc">
<li><p>If you are on a slow machine, you may want to
set <code class="varname">USE_BULK_BROKEN_CHECK</code> to

<li><p>If you are doing bulk builds from a read-only
copy of pkgsrc, you have to set <code class="varname">BULKFILESDIR</code>
to the directory where all log files are created. Otherwise the
log files are created in the pkgsrc directory.</p></li>
<li><p>Another important variable is
<code class="varname">BULK_PREREQ</code>, which is a list of packages that
should be always available while building other
packages.</p></li>
</ul></div>
<p>Some other options are scattered in the pkgsrc
infrastructure:</p>
<div class="itemizedlist"><ul type="disc">
<li><p><code class="varname">ALLOW_VULNERABLE_PACKAGES</code>
should be set to <code class="literal">yes</code>. The purpose of the bulk
builds is creating binary packages, no matter if they are
vulnerable or not. When uploading the packages to a public
server, the vulnerable packages will be put into a directory of
their own. Leaving this variable unset would prevent the bulk
build system from even trying to build them, so possible
building errors would not show up.</p></li>
<li><p><code class="varname">CHECK_FILES</code>
(<code class="filename">pkgsrc/mk/check/check-files.mk</code>) can be set to
“<span class="quote">yes</span>” to check that the installed set of files
matches the <code class="filename">PLIST</code>.</p></li>
<li><p><code class="varname">CHECK_INTERPRETER</code>
(<code class="filename">pkgsrc/mk/check/check-interpreter.mk</code>) can be set to
“<span class="quote">yes</span>” to check that the installed
“<span class="quote">#!</span>”-scripts will find their
interpreter.</p></li>
<li><p><code class="varname">PKGSRC_RUN_TEST</code> can be
set to “<span class="quote"><code class="literal">yes</code></span>” to run each
package's self-test before installing it. Note that some
packages make heavy use of “<span class="quote">good</span>” random
numbers, so you need to assure that the machine on which you
are doing the bulk builds is not completely idle. Otherwise
some test programs will seem to hang, while they are just
waiting for new random data to be
available.</p></li>
</ul></div>

certain site-specific tasks at the end of the pre-build

<code class="filename">pre-build.local</code> exists in
<code class="filename">/usr/pkgsrc/mk/bulk</code>, it will be executed

stage. An example use of
<code class="filename">pre-build.local</code> is to have the line:</p>
<pre class="screen">echo "I do not have enough disk space to build this pig." \
> misc/openoffice/$BROKENF</pre>
<p>to prevent the system from trying to build a particular package
which requires nearly 3 GB of disk space.</p>

<p>As <code class="filename">/usr/pkg</code> will be completely
deleted at the start of bulk builds, make sure your login
shell is placed somewhere else. Either drop it into
<code class="filename">/usr/local/bin</code> (and adjust your login
shell in the passwd file), or (re-)install it via
<a class="citerefentry" href="http://netbsd.gw.com/cgi-bin/man-cgi?pkg_add+1+NetBSD-current"><span class="citerefentry"><span class="refentrytitle">pkg_add</span>(1)</span></a> from <code class="filename">/etc/rc.local</code>, so
you can login after a reboot (remember that your current
process won't die if the package is removed, you just can't
start any new instances of the shell any more). Also, if you
use NetBSD earlier than 1.5, or you still want to use the pkgsrc
version of ssh for some reason, be sure to install ssh before
starting it from <code class="filename">rc.local</code>:</p>
<pre class="programlisting">
(cd /usr/pkgsrc/security/ssh && make bulk-install)
if [ -f /usr/pkg/etc/rc.d/sshd ]; then

<a name="setting-up-a-sandbox"></a>7.3.6. Setting up a sandbox for chrooted builds</h3></div></div></div>
<p>If you don't want all the packages nuked from a machine
(rendering it useless for anything but pkg compiling), there
is the possibility of doing the package bulk build inside a
chroot environment.</p>
<p>The first step is to set up a chroot sandbox,
e.g. <code class="filename">/usr/sandbox</code>. This can be done by
using null mounts, or manually.</p>
<p>There is a shell script called
<code class="filename">pkgsrc/mk/bulk/mksandbox</code> which will set
up the sandbox environment using null mounts. It will also
create a script called <code class="filename">sandbox</code> in the
root of the sandbox environment, which will allow the null
mounts to be activated using the <span class="command"><strong>sandbox
mount</strong></span> command and deactivated using the
<span class="command"><strong>sandbox umount</strong></span> command.</p>
<p>To set up a sandbox environment by hand, after extracting all
the sets from a NetBSD installation or doing a <span class="command"><strong>make
distribution DESTDIR=/usr/sandbox</strong></span> in
<code class="filename">/usr/src/etc</code>, be sure the following items
are present and properly configured:</p>

<li><p>Adjust <code class="filename">mk/bulk/build.conf</code> to suit your needs.</p></li>

<p>When the chroot sandbox is set up, you can start

<code class="prompt">#</code> <strong class="userinput"><code>cd /usr/sandbox/usr/pkgsrc</code></strong>
<code class="prompt">#</code> <strong class="userinput"><code>sh mk/bulk/do-sandbox-build</code></strong>

<p>This will just jump inside the sandbox and start building. At
the end of the build, mail will be sent with the results of
the build. Created binary pkgs will be in
<code class="filename">/usr/sandbox/usr/pkgsrc/packages</code>
(wherever that points/mounts to/from).</p>

<div class="titlepage"><div><div><h3 class="title">
<a name="building-a-partial-set"></a>7.3.7. Building a partial set of packages</h3></div></div></div>
<p>In addition to building a complete set of all packages in

may be used to build a subset of the packages contained in

</ul></div>
<p>will define the set of packages which should be built.
The bulk build code will also include any packages which are
needed as dependencies for the explicitly listed packages.</p>
<p>One use of this is to do a bulk build with

periodically to have a complete set of the binary packages
needed for your site available without the overhead of
building extra packages that are not needed.</p>

<div class="sect2" lang="en">
<div class="titlepage"><div><div><h3 class="title">
<a name="bulk-upload"></a>7.3.8. Uploading results of a bulk build</h3></div></div></div>
<p>This section describes how pkgsrc developers can upload binary
pkgs built by bulk builds to ftp.NetBSD.org.</p>
<p>If you would like to automatically create checksum files for the
binary packages you intend to upload, remember to set
<code class="varname">MKSUMS=yes</code> in your
<code class="filename">mk/bulk/build.conf</code>.</p>
<p>If you would like to PGP sign the checksum files (highly
recommended!), remember to set
<code class="varname">SIGN_AS=username@NetBSD.org</code> in your
<code class="filename">mk/bulk/build.conf</code>. This will prompt you for
your GPG password to sign the files before uploading everything.</p>
<p>Then, make sure that you have <code class="varname">RSYNC_DST</code>
set properly in your <code class="filename">mk/bulk/build.conf</code>
file, i.e. adjust it to something like one of the following:</p>
<pre class="screen">RSYNC_DST=ftp.NetBSD.org:/pub/NetBSD/packages/packages-200xQy/NetBSD-a.b.c/arch/upload </pre>
<p>Please use appropriate values for "packages-200xQy",
"NetBSD-a.b.c" and "arch" here. If your login on ftp.NetBSD.org
is different from your local login, write your login directly
into the variable, e.g. my local account is "feyrer", but for my
login "hubertf", I use:</p>
<pre class="screen">RSYNC_DST=hubertf@ftp.NetBSD.org:/pub/NetBSD/packages/packages-200xQy/NetBSD-a.b.c/arch/upload</pre>
<p>A separate <code class="filename">upload</code> directory is used
here to allow "closing" the directory during upload. To do
so, run the following command on ftp.NetBSD.org next:</p>
<pre class="screen">nbftp% <strong class="userinput"><code>mkdir -p -m 750 /pub/NetBSD/packages/packages-200xQy/NetBSD-a.b.c/arch/upload</code></strong></pre>
<p>Please note that <code class="filename">/pub/NetBSD/packages</code> is
only appropriate for packages for the NetBSD operating
system. Binary packages for other operating systems should go
into <code class="filename">/pub/pkgsrc</code>.</p>
<p>Before uploading the binary pkgs, ssh authentication needs
to be set up. This example shows how to set up temporary keys
for the root account <span class="emphasis"><em>inside the sandbox</em></span>
(assuming that no keys should be present there usually):</p>
<pre class="screen">
<code class="prompt">#</code> <strong class="userinput"><code>chroot /usr/sandbox</code></strong>
chroot-<code class="prompt">#</code> <strong class="userinput"><code>rm $HOME/.ssh/id-dsa*</code></strong>
chroot-<code class="prompt">#</code> <strong class="userinput"><code>ssh-keygen -t dsa</code></strong>
chroot-<code class="prompt">#</code> <strong class="userinput"><code>cat $HOME/.ssh/id-dsa.pub</code></strong>
</pre>
<p>Now take the output of <code class="filename">id-dsa.pub</code> and
append it to your <code class="filename">~/.ssh/authorized_keys</code>
file on ftp.NetBSD.org. You can remove the key after the
upload is done!</p>
<p>Next, test if your ssh connection really works:</p>
<pre class="screen">chroot-<code class="prompt">#</code> <strong class="userinput"><code>ssh ftp.NetBSD.org date</code></strong> </pre>
<p>Use "-l yourNetBSDlogin" here as appropriate!</p>
<p>Now after all this works, you can exit the sandbox and start
the upload:</p>
<pre class="screen">
chroot-<code class="prompt">#</code> <strong class="userinput"><code>exit</code></strong>
<code class="prompt">#</code> <strong class="userinput"><code>cd /usr/sandbox/usr/pkgsrc</code></strong>
<code class="prompt">#</code> <strong class="userinput"><code>sh mk/bulk/do-sandbox-upload</code></strong>
</pre>
<p>The upload process may take quite some time. Use <a class="citerefentry" href="http://netbsd.gw.com/cgi-bin/man-cgi?ls+1+NetBSD-current"><span class="citerefentry"><span class="refentrytitle">ls</span>(1)</span></a> or
<a class="citerefentry" href="http://netbsd.gw.com/cgi-bin/man-cgi?du+1+NetBSD-current"><span class="citerefentry"><span class="refentrytitle">du</span>(1)</span></a> on the FTP server to monitor progress of the
upload. The upload script will take care of not uploading
restricted packages and putting vulnerable packages into the
<code class="filename">vulnerable</code> subdirectory.</p>
<p>After the upload has ended, first thing is to revoke ssh access:</p>
<pre class="screen">nbftp% <strong class="userinput"><code>vi ~/.ssh/authorized_keys</code></strong>
Gdd:x! </pre>
<p>Use whatever is needed to remove the key you've entered
before! Last, move the uploaded packages out of the
<code class="filename">upload</code> directory to have them accessible
to everyone:</p>
<pre class="screen">
nbftp% <strong class="userinput"><code>cd /pub/NetBSD/packages/packages-200xQy/NetBSD-a.b.c/arch</code></strong>
nbftp% <strong class="userinput"><code>mv upload/* .</code></strong>
nbftp% <strong class="userinput"><code>rmdir upload</code></strong>
nbftp% <strong class="userinput"><code>chmod 755 .</code></strong>
</pre>

<p>After your pkgsrc bulk-build has completed, you may wish to
create a CD-ROM set of the resulting binary packages to assist
in installing packages on other machines. The
<a href="ftp://ftp.NetBSD.org/pub/pkgsrc/current/pkgsrc/pkgtools/cdpack/README.html" target="_top"><code class="filename">pkgtools/cdpack</code></a> package provides
a simple tool for creating the ISO 9660 images.
<span class="command"><strong>cdpack</strong></span> arranges the packages on the CD-ROMs in a
way that keeps all the dependencies for a given package on the same
CD as that package.</p>
<div class="sect2" lang="en">
<div class="titlepage"><div><div><h3 class="title">
<a name="cdpack-example"></a>7.5.1. Example of cdpack</h3></div></div></div>
<p>Complete documentation for cdpack is found in the cdpack(1)
man page. The following short example assumes that the binary
packages are left in
<code class="filename">/usr/pkgsrc/packages/All</code> and that
sufficient disk space exists in <code class="filename">/u2</code> to
hold the ISO 9660 images.</p>
<pre class="screen">

<code class="prompt">#</code> <strong class="userinput"><code>cdpack /usr/pkgsrc/packages/All /u2/images</code></strong>
</pre>
<p>If you wish to include a common set of files
(<code class="filename">COPYRIGHT</code>, <code class="filename">README</code>,
etc.) on each CD in the collection, then you need to create a
directory which contains these files. e.g.</p>
<pre class="screen">
<code class="prompt">#</code> <strong class="userinput"><code>mkdir /tmp/common</code></strong>
<code class="prompt">#</code> <strong class="userinput"><code>echo "This is a README" > /tmp/common/README</code></strong>

<code class="prompt">#</code> <strong class="userinput"><code>echo "#!/bin/sh" > /tmp/common/bin/myscript</code></strong>
<code class="prompt">#</code> <strong class="userinput"><code>echo "echo Hello world" >> /tmp/common/bin/myscript</code></strong>
<code class="prompt">#</code> <strong class="userinput"><code>chmod 755 /tmp/common/bin/myscript</code></strong>
</pre>
<p>Now create the images:</p>
<pre class="screen"><code class="prompt">#</code> <strong class="userinput"><code>cdpack -x /tmp/common /usr/pkgsrc/packages/All /u2/images</code></strong></pre>
<p>Each image will contain <code class="filename">README</code>,

<p>The files that are installed by pkgsrc are organized in a way that
is similar to what you find in the <code class="filename">/usr</code> directory
of the base system. But some details are different. This is because
pkgsrc initially came from FreeBSD and had adopted its file system
hierarchy. Later it was largely influenced by NetBSD. But no matter
which operating system you are using pkgsrc with, you can expect the
same layout for pkgsrc.</p>
<p>There are mainly four root directories for pkgsrc, which are all
configurable in the <code class="filename">bootstrap/bootstrap</code> script.
When pkgsrc has been installed as root, the default locations
are:</p>
<pre class="programlisting">
LOCALBASE= /usr/pkg
PKG_SYSCONFBASE= /usr/pkg/etc
VARBASE= /var
PKG_DBDIR= /var/db/pkg
</pre>
<p>In unprivileged mode (when pkgsrc has been installed as any other
user), the default locations are:</p>
<pre class="programlisting">
LOCALBASE= ${HOME}/pkg
PKG_SYSCONFBASE= ${HOME}/pkg/etc
VARBASE= ${HOME}/pkg/var
PKG_DBDIR= ${HOME}/pkg/var/db/pkg
</pre>
<p>What these four directories are for, and what they look like is
explained below.</p>
<div class="itemizedlist"><ul type="disc">
<li><p><code class="varname">LOCALBASE</code> corresponds to the
<code class="filename">/usr</code> directory in the base system. It is the

<code class="filename">include</code>, <code class="filename">lib</code>,

<a name="non-root-pkgsrc"></a>9.4. How to use pkgsrc as non-root</h2></div></div></div>
<p>If you want to use pkgsrc as non-root user, you can set some
variables to make pkgsrc work under these conditions. At the very least,
you need to set <code class="varname">UNPRIVILEGED</code> to “<span class="quote">yes</span>”; this
will turn on unprivileged mode and set multiple related variables to allow
installation of packages as non-root.</p>
<p>In case the defaults are not enough, you may want to tune some other
variables used. For example, if the automatic user/group detection leads
to incorrect values (or not the ones you would like to use), you can change
them by setting <code class="varname">UNPRIVILEGED_USER</code> and
<code class="varname">UNPRIVILEGED_GROUP</code> respectively.</p>
<p>As regards bootstrapping, please note that the
<span class="command"><strong>bootstrap</strong></span> script will ease non-root configuration when
given the “<span class="quote">--ignore-user-check</span>” flag, as it will choose and
use multiple default directories under <code class="filename">~/pkg</code> as the
installation targets. These directories can be overridden by the
“<span class="quote">--prefix</span>” flag provided by the script, as well as some others
that allow finer tuning of the tree layout.</p>

<a name="resume-transfers"></a>9.5. How to resume transfers when fetching distfiles?</h2></div></div></div>
<p>By default, resuming transfers in pkgsrc is disabled, but you can
enable this feature by adding the option
<code class="varname">PKG_RESUME_TRANSFERS=YES</code> into
<a class="link" href="#mk.conf"><code class="filename">mk.conf</code></a>. If, during a fetch step, an incomplete
distfile is found, pkgsrc will try to resume it.</p>
<p>You can also
use a different program than the default <a class="citerefentry" href="http://netbsd.gw.com/cgi-bin/man-cgi?ftp+1+NetBSD-current"><span class="citerefentry"><span class="refentrytitle">ftp</span>(1)</span></a> by changing the
<code class="varname">FETCH_CMD</code> variable. Don't forget to set
<code class="varname">FETCH_RESUME_ARGS</code> and
<code class="varname">FETCH_OUTPUT_ARGS</code> if you are not using default
values.</p>
<p>For example, if you want to use
<code class="filename">wget</code> to resume downloads, you'll have to use something
like:</p>
<pre class="programlisting">

<a name="fetch-behind-firewall"></a>9.7. How to fetch files from behind a firewall</h2></div></div></div>
<p>If you are sitting behind a firewall which does not allow direct
connections to Internet hosts (i.e. non-NAT), you may specify the
relevant proxy hosts. This is done using an environment variable in the
form of a URL, e.g. in Amdahl, the machine
“<span class="quote">orpheus.amdahl.com</span>” is one of the firewalls, and it uses
port 80 as the proxy port number. So the proxy environment variables
are:</p>

<a name="passive-ftp"></a>9.8. How do I tell <span class="command"><strong>make fetch</strong></span> to do passive FTP?</h2></div></div></div>
<p>This depends on which utility is used to retrieve distfiles. From
<code class="filename">bsd.pkg.mk</code>, <code class="varname">FETCH_CMD</code> is assigned
the first available command from the following list:</p>
<div class="itemizedlist"><ul type="disc">
<li><p><code class="filename">${LOCALBASE}/bin/ftp</code></p></li>
<li><p><code class="filename">/usr/bin/ftp</code></p></li>
</ul></div>
<p>On a default NetBSD installation, this will be
<code class="filename">/usr/bin/ftp</code>, which automatically tries passive
connections first, and falls back to active connections if the server
refuses to do passive. For the other tools, add the following to your
<a class="link" href="#mk.conf"><code class="filename">mk.conf</code></a> file:
<code class="varname">PASSIVE_FETCH=1</code>.</p>
<p>Having that option present will prevent

<a name="fetching-all-distfiles"></a>9.9. How to fetch all distfiles at once</h2></div></div></div>
<p>You would like to download all the distfiles in a single batch
from work or university, where you can't run a <span class="command"><strong>make

but downloading the entire directory may not be appropriate.</p>
<p>The answer here is to do a <span class="command"><strong>make fetch-list</strong></span> in
<code class="filename">/usr/pkgsrc</code> or one of its subdirectories, carry the
resulting list to your machine at work/school and use it there. If you
don't have a NetBSD-compatible <a class="citerefentry" href="http://netbsd.gw.com/cgi-bin/man-cgi?ftp+1+NetBSD-current"><span class="citerefentry"><span class="refentrytitle">ftp</span>(1)</span></a> (like tnftp) at work, don't

<p>As the system administrator, you can choose where configuration files
are installed. The default settings make all these files go into
<code class="filename">${PREFIX}/etc</code> or some of its subdirectories; this may
be suboptimal depending on your expectations (e.g., a read-only,
NFS-exported <code class="varname">PREFIX</code> with a need of per-machine

<p>In order to change the defaults, you can modify the

<p>Furthermore, you can change this value on a per-package basis by
setting the <code class="varname">PKG_SYSCONFDIR.${PKG_SYSCONFVAR}</code> variable.
<code class="varname">PKG_SYSCONFVAR</code>'s value usually matches the name of the

<p>Please be aware that there can often be bugs in third-party software,

attackers. In an effort to lessen the exposure, the NetBSD packages team
maintains a database of known-exploits to packages which have at one time
been included in pkgsrc. The database can be downloaded automatically, and
a security audit of all packages installed on a system can take place. To
do this, install the <a href="ftp://ftp.NetBSD.org/pub/pkgsrc/current/pkgsrc/security/audit-packages/README.html" target="_top"><code class="filename">security/audit-packages</code></a> package. It has two

you should run <span class="command"><strong>make patch</strong></span> in the package
directory and then inspect any <code class="filename">Makefile</code> and
<code class="filename">Makefile.in</code> for whether they define
<code class="varname">CFLAGS</code> explicitly. Usually you can remove
these lines. But be aware that some “<span class="quote">smart</span>”
programmers write so bad code that it only works for the
specific combination of <code class="varname">CFLAGS</code> they have
chosen.</p>

<p>You have modified a file from pkgsrc, and someone else has
modified that same file afterwards in the CVS repository. Both changes
are in the same region of the file, so when you updated pkgsrc, the
<code class="literal">cvs</code> command marked the conflicting changes in the
file. Because of these markers, the file is no longer a valid
<code class="filename">Makefile</code>.</p>
<p>Have a look at that file, and if you don't need your local changes
anymore, you can remove that file and run <span class="command"><strong>cvs -q update

category in which you want to place your package. You can also create a
directory of your own (maybe called <code class="filename">local</code>). In that
category directory, create another directory for your package and change
into it.</p></li>
<li><p>Run the program <span class="command"><strong>url2pkg</strong></span>, which will ask
you for a URL. Enter the URL of the distribution file (in most cases a
<code class="filename">.tar.gz</code> file) and watch how the basic ingredients
of your package are created automatically. The distribution file is
extracted automatically to fill in some details in the
<code class="filename">Makefile</code> that would otherwise have to be done
manually.</p></li>
<li>
<p>Examine the extracted files to determine the dependencies of
your package. Ideally, this is mentioned in some
<code class="filename">README</code> file, but things may differ. For each of
these dependencies, look where it exists in pkgsrc, and if there is a
file called <code class="filename">buildlink3.mk</code> in that directory, add a
line to your package <code class="filename">Makefile</code> which includes that
file just before the last line. If the
<code class="filename">buildlink3.mk</code> file does not exist, add a
<code class="varname">DEPENDS</code> line to the Makefile, which specifies the
version of the dependency and where it can be found in pkgsrc. This line
should be placed in the third paragraph. If the dependency is only
needed for building the package, but not when using it, use
<code class="varname">BUILD_DEPENDS</code> instead of <code class="varname">DEPENDS</code>.
Your package may then look like this:</p>
<pre class="programlisting">
[...]
BUILD_DEPENDS+= lua>=5.0:../../lang/lua
DEPENDS+= screen-[0-9]*:../../misc/screen
DEPENDS+= screen>=4.0:../../misc/screen
[...]
.include "../../<em class="replaceable"><code>category</code></em>/<em class="replaceable"><code>package</code></em>/buildlink3.mk"
.include "../../devel/glib2/buildlink3.mk"
.include "../../mk/bsd.pkg.mk"
</pre>
</li>
<li><p>Run <span class="command"><strong>pkglint</strong></span> to see what things still need
to be done to make your package a “<span class="quote">good</span>” one. If you don't
know what pkglint's warnings want to tell you, try <span class="command"><strong>pkglint
--explain</strong></span> or <span class="command"><strong>pkglint
-e</strong></span>, which outputs additional
explanations.</p></li>
<li><p>In many cases the package is not yet ready to build. You can
find instructions for the most common cases in the next section, <a class="xref" href="#creating.common" title="10.1. Common types of packages">Section 10.1, “Common types of packages”</a>. After you have followed the instructions
over there, you can hopefully continue here.</p></li>
<li><p>Run <span class="command"><strong>bmake clean</strong></span> to clean the working
directory from the extracted files. Besides these files, a lot of cache
files and other system information has been saved in the working
directory, which may become wrong after you edited the
<code class="filename">Makefile</code>.</p></li>
<li><p>Now, run <span class="command"><strong>bmake</strong></span> to build the package. For
the various things that can go wrong in this phase, consult <a class="xref" href="#fixes" title="Chapter 19. Making your package work">Chapter 19, <i>Making your package work</i></a>.</p></li>
<li><p>When the package builds fine, the next step is to install
the package. Run <span class="command"><strong>bmake install</strong></span> and hope that
everything works.</p></li>
<li><p>Up to now, the file <code class="filename">PLIST</code>, which
contains a list of the files that are installed by the package, is
nearly empty. Run <span class="command"><strong>bmake print-PLIST
>PLIST</strong></span> to generate a probably correct list. Check
the file using your preferred text editor to see if the list of
files looks plausible.</p></li>
<li><p>Run <span class="command"><strong>pkglint</strong></span> again to see if the generated
<code class="filename">PLIST</code> contains garbage or not.</p></li>
<li><p>When you ran <span class="command"><strong>bmake install</strong></span>, the package
has been registered in the database of installed files, but with an
empty list of files. To fix this, run <span class="command"><strong>bmake deinstall</strong></span>
and <span class="command"><strong>bmake install</strong></span> again. Now the package is
registered with the list of files from
<code class="filename">PLIST</code>.</p></li>
<li><p>Run <span class="command"><strong>bmake package</strong></span> to create a binary
package from the set of installed files.</p></li>

<p>Looking at the file <code class="filename">pkgsrc/doc/TODO</code>, I saw
that the “<span class="quote">nvu</span>” package has not yet been imported into
pkgsrc. As the description says it has to do with the web, the obvious
choice for the category is “<span class="quote">www</span>”.</p>
<pre class="programlisting">
<code class="prompt">$</code> mkdir www/nvu
<code class="prompt">$</code> cd www/nvu

<p>The web site says that the sources are available as a tar file, so
I fed that URL to the <span class="command"><strong>url2pkg</strong></span> program:</p>
<pre class="programlisting">
<code class="prompt">$</code> url2pkg http://cvs.nvu.com/download/nvu-1.0-sources.tar.bz2
</pre>
<p>My editor popped up, and I added a <code class="varname">PKGNAME</code> line
below the <code class="varname">DISTNAME</code> line, as the package name should
not have the word “<span class="quote">sources</span>” in it. I also filled in the
<code class="varname">MAINTAINER</code>, <code class="varname">HOMEPAGE</code> and
<code class="varname">COMMENT</code> fields. Then the package
<code class="filename">Makefile</code> looked like that:</p>
<pre class="programlisting">

<p>Now that the package has been extracted, let's see what's inside
it. The package has a <code class="filename">README.txt</code>, but that only
says something about mozilla, so it's probably useless for seeing what
dependencies this package has. But since there is a GNU configure script
in the package, let's hope that it will complain about everything it
needs.</p>

<p>That worked quite well. So I opened the package Makefile in my
editor, and since it already has a <code class="varname">USE_TOOLS</code> line, I
just appended “<span class="quote">perl</span>” to it. Since the dependencies of the
package have changed now, and since a perl wrapper is automatically
installed in the “<span class="quote">tools</span>” phase, I need to build the package
from scratch.</p>

</pre>
<p>Now to the other dependencies. The first question is: Where is the
GTK package hidden in pkgsrc?</p>
<pre class="programlisting">
<code class="prompt">$</code> echo ../../*/gtk*
[many packages ...]
<code class="prompt">$</code> echo ../../*/gtk
../../x11/gtk
<code class="prompt">$</code> echo ../../*/gtk2
../../x11/gtk2
<code class="prompt">$</code> echo ../../*/gtk2/bui*
../../x11/gtk2/buildlink3.mk
</pre>
<p>The first try was definitely too broad. The second one had exactly
one result, which is very good. But there is one pitfall with GNOME
packages. Before GNOME 2 had been released, there were already many
GNOME 1 packages in pkgsrc. To be able to continue to use these
packages, the GNOME 2 packages were imported as separate packages, and
their names usually have a “<span class="quote">2</span>” appended. So I checked
whether this was the case here, and indeed it was.</p>
<p>Since the GTK2 package has a <code class="filename">buildlink3.mk</code>
file, adding the dependency is very easy. I just inserted an
<code class="literal">.include</code> line before the last line of the package
<code class="filename">Makefile</code>, so that it now looks like this:</p>
<pre class="programlisting">
[...]
.include "../../x11/gtk2/buildlink3.mk"
.include "../../mk/bsd.pkg.mk
</pre>
<p>After another <span class="command"><strong>bmake clean && bmake</strong></span>, the answer
was:</p>
<pre class="programlisting">

checking for GTK - version >= 1.2.0... no
*** Could not run GTK test program, checking why...
*** The test program failed to compile or link. See the file config.log for the
*** exact error that occured. This usually means GTK was incorrectly installed
*** or that you have moved GTK since it was installed. In the latter case, you
*** may want to edit the gtk-config script: /home/roland/pkg/bin/gtk-config
configure: error: Test for GTK failed.
[...]
</pre>
<p>In this particular case, the assumption that “<span class="quote">every package
prefers GNOME 2</span>” had been wrong. The first of the lines above
told me that this package really wanted to have the GNOME 1 version of
GTK. If the package had looked for GTK2, it would have looked for
<span class="command"><strong>pkg-config</strong></span> instead of <span class="command"><strong>gtk-config</strong></span>.
So I changed the <code class="literal">x11/gtk2</code> to
<code class="literal">x11/gtk</code> in the package <code class="filename">Makefile</code>,
and tried again.</p>

<p>The package still does not find all of its dependencies. Now the
question is: Which package provides the
<code class="filename">libIDL/IDL.h</code> header file?</p>
<pre class="programlisting">
<code class="prompt">$</code> echo ../../*/*idl*
../../devel/py-idle ../../wip/idled ../../x11/acidlaunch
<code class="prompt">$</code> echo ../../*/*IDL*
../../net/libIDL
</pre>
<p>Let's take the one from the second try. So I included the
<code class="filename">../../net/libIDL/buildlink3.mk</code> file and tried
again. But the error didn't change. After digging through some of the
code, I concluded that the build process of the package was broken and
couldn't have ever worked, but since the Mozilla source tree is quite
large, I didn't want to fix it. So I added the following to the package
<code class="filename">Makefile</code> and tried again:</p>
<pre class="programlisting">
CPPFLAGS+= -I${BUILDLINK_PREFIX.libIDL}/include/libIDL-2.0
BUILDLINK_TRANSFORM+= -l:IDL:IDL-2
</pre>
<p>The latter line is needed because the package expects the library
<code class="filename">libIDL.so</code>, but only
<code class="filename">libIDL-2.so</code> is available. So I told the compiler
wrapper to rewrite that on the fly.</p>
<p>The next problem was related to a recent change of the FreeType
interface. I looked up in <a href="ftp://ftp.NetBSD.org/pub/pkgsrc/current/pkgsrc/www/seamonkey/README.html" target="_top"><code class="filename">www/seamonkey</code></a>
which patch files were relevant for this issue and copied them to the
<code class="filename">patches</code> directory. Then I retried, fixed the
patches so that they applied cleanly and retried again. This time,
everything worked.</p>

<p>Whenever you're preparing a package, there are a number of
files involved which are described in the following
sections.</p>
<div class="sect1" lang="en">
<div class="titlepage"><div><div><h2 class="title" style="clear: both">
<a name="components.Makefile"></a>11.1. <code class="filename">Makefile</code>
</h2></div></div></div>
<p>Building, installation and creation of a binary package are all
controlled by the package's <code class="filename">Makefile</code>.
The <code class="filename">Makefile</code> describes various things about
a package, for example from where to get it, how to configure,
build, and install it.</p>
<p>A package <code class="filename">Makefile</code> contains several
sections that describe the package.</p>
<p>In the first section there are the following variables, which
should appear exactly in the order given here. The order and
grouping of the variables is mostly historical and has no further
meaning.</p>
<div class="itemizedlist"><ul type="disc">
<li><p><code class="varname">DISTNAME</code> is the basename of the
distribution file to be downloaded from the package's
website.</p></li>
<li><p><code class="varname">PKGNAME</code> is the name of the
package, as used by pkgsrc. You only need to provide it if
<code class="varname">DISTNAME</code> (which is the default) is not a good
name for the package in pkgsrc. Usually it is the pkgsrc
directory name together with the version number. It must match the
regular expression
<code class="varname">^[A-Za-z0-9][A-Za-z0-9-_.+]*$</code>, that is, it
starts with a letter or digit, and contains only letters, digits,
dashes, underscores, dots and plus signs.</p></li>
<li><p><code class="varname">SVR4_PKGNAME</code> is the name of
the package file to create if the <code class="varname">PKGNAME</code>
isn't unique on a SVR4 system. The default is
<code class="varname">PKGNAME</code>, which may be shortened when you use
<a href="ftp://ftp.NetBSD.org/pub/pkgsrc/current/pkgsrc/pkgtools/gensolpkg/README.html" target="_top"><code class="filename">pkgtools/gensolpkg</code></a>. Only add
<code class="varname">SVR4_PKGNAME</code> if <code class="varname">PKGNAME</code>
does not produce an unique package name on a SVR4 system.
The length of <code class="varname">SVR4_PKGNAME</code> is limited to 5
characters.</p></li>
<li>
<p><code class="varname">CATEGORIES</code> is a list of categories
which the package fits in. You can choose any of the top-level
directories of pkgsrc for it.</p>
<p>Currently the following values are available for
<code class="varname">CATEGORIES</code>. If more than
one is used, they need to be separated by spaces:</p>
<pre class="programlisting">

</ul></div>
<p>The second section contains information about separately
downloaded patches, if any.
</p>
<div class="itemizedlist"><ul type="disc">
<li><p><code class="varname">PATCHFILES:</code>
Name(s) of additional files that contain distribution patches.
There is no default. pkgsrc will look for them at
<code class="varname">PATCH_SITES</code>.
They will automatically be uncompressed before patching if
the names end with <code class="filename">.gz</code> or
<code class="filename">.Z</code>.</p></li>
<li><p><code class="varname">PATCH_SITES</code>:
Primary location(s) for distribution patch files (see
<code class="varname">PATCHFILES</code> below) if not found locally.</p></li>
</ul></div>
<p>The third section contains the following variables.
</p>
<div class="itemizedlist"><ul type="disc">
<li><p><code class="varname">MAINTAINER</code> is the email address
of the person who feels responsible for this package, and who is
most likely to look at problems or questions regarding this
package which have been reported with <a class="citerefentry" href="http://netbsd.gw.com/cgi-bin/man-cgi?send-pr+1+NetBSD-current"><span class="citerefentry"><span class="refentrytitle">send-pr</span>(1)</span></a>. Other
developers should contact the <code class="varname">MAINTAINER</code> before
making major changes to the package. When packaging a new program,
set <code class="varname">MAINTAINER</code> to yourself. If you really can't
maintain the package for future updates, set it to
<code class="email"><<a class="email" href="mailto:pkgsrc-users@NetBSD.org">pkgsrc-users@NetBSD.org</a>></code>.</p></li>
<li><p><code class="varname">HOMEPAGE</code> is a URL where users can
find more information about the package.</p></li>
<li><p><code class="varname">COMMENT</code> is a one-line
description of the package (should not include the package
name).</p></li>
</ul></div>
<p>Other variables that affect the build:
</p>
<div class="itemizedlist"><ul type="disc"><li>
<p><code class="varname">WRKSRC</code>: The directory where the
interesting distribution files of the package are found. The
default is <code class="filename">${WRKDIR}/${DISTNAME}</code>, which
works for most packages.</p>
<p>If a package doesn't create a subdirectory for itself
(most GNU software does, for instance), but extracts itself in
the current directory, you should set
<code class="varname">WRKSRC=${WRKDIR}</code>.</p>
<p>If a package doesn't create a subdirectory with the
name of <code class="varname">DISTNAME</code> but some different name,
set <code class="varname">WRKSRC</code> to point to the proper name in
<code class="filename">${WRKDIR}</code>, for example
<code class="varname">WRKSRC=${WRKDIR}/${DISTNAME}/unix</code>. See
<a href="ftp://ftp.NetBSD.org/pub/pkgsrc/current/pkgsrc/lang/tcl/README.html" target="_top"><code class="filename">lang/tcl</code></a> and <a href="ftp://ftp.NetBSD.org/pub/pkgsrc/current/pkgsrc/x11/tk/README.html" target="_top"><code class="filename">x11/tk</code></a> for other examples.</p>
<p>The name of the working directory created by pkgsrc is
taken from the <code class="varname">WRKDIR_BASENAME</code>
variable. By default, its value is
<code class="filename">work</code>. If you want to use the same
pkgsrc tree for building different kinds of binary packages,
you can change the variable according to your needs. Two
other variables handle common cases of setting
<code class="varname">WRKDIR_BASENAME</code> individually. If
<code class="varname">OBJHOSTNAME</code> is defined in

<p>The <code class="filename">distinfo</code> file contains the message
digest, or checksum, of each distfile needed for the package. This
ensures that the distfiles retrieved from the Internet have not been
corrupted during transfer or altered by a malign force to introduce
a security hole. Due to recent rumor about weaknesses of digest
algorithms, all distfiles are protected using both SHA1 and RMD160
message digests, as well as the file size.</p>
<p>The <code class="filename">distinfo</code> file also contains the
checksums for all the patches found in the
<code class="filename">patches</code> directory (see <a class="xref" href="#components.patches" title="11.3. patches/*">Section 11.3, “patches/*”</a>).</p>
<p>To regenerate the <code class="filename">distinfo</code> file, use the
<span class="command"><strong>make makedistinfo</strong></span> or <span class="command"><strong>make mdi</strong></span>

<p>Some packages have different sets of distfiles depending on
the platform, for example <a href="ftp://ftp.NetBSD.org/pub/pkgsrc/current/pkgsrc/www/navigator/README.html" target="_top"><code class="filename">www/navigator</code></a>). These are kept in the same
<code class="filename">distinfo</code> file and care should be taken when

<p>Many packages still don't work out-of-the box on the various
platforms that are supported by pkgsrc. Therefore, a number of custom
patch files are needed to make the package work. These patch files are
found in the <code class="filename">patches/</code> directory.</p>
<p>In the <span class="emphasis"><em>patch</em></span> phase, these patches are
applied to the files in <code class="varname">WRKSRC</code> directory after
extracting them, in <a class="ulink" href="http://www.opengroup.org/onlinepubs/009695399/utilities/xcu_chap02.html#tag_02_13_03" target="_top">alphabetic
order</a>, so <code class="filename">patch-aa</code> is applied before
<code class="filename">patch-ab</code>, etc.</p>

<div class="titlepage"><div><div><h3 class="title">
<a name="components.patch.structure"></a>11.3.1. Structure of a single patch file</h3></div></div></div>
<p>The <code class="filename">patch-*</code> files should be in
<span class="command"><strong>diff -bu</strong></span> format, and apply without a fuzz to avoid
problems. (To force patches to apply with fuzz you can set
<code class="varname">PATCH_FUZZ_FACTOR=-F2</code>). Furthermore, each patch
should contain only changes for a single file, and no file should be
patched by more than one patch file. This helps to keep future
modifications simple.</p>
<p>Each patch file is structured as follows: In the first line,
there is the RCS Id of the patch itself. The second line should be
empty for aesthetic reasons. After that, there should be a comment for
each change that the patch does. There are a number of standard
cases:</p>
<div class="itemizedlist"><ul type="disc">
<li><p>Patches that replace the <code class="literal">==</code>
operator for <a class="citerefentry" href="http://netbsd.gw.com/cgi-bin/man-cgi?test+1+NetBSD-current"><span class="citerefentry"><span class="refentrytitle">test</span>(1)</span></a> with <code class="literal">=</code> in shell scripts
should contain a reference to , to avoid
redundant explanations.</p></li>
<li><p>Patches for commonly known vulnerabilities should
mention the vulnerability ID (CAN, CVE).</p></li>
<li><p>Patches that change source code should mention the
platform and other environment (for example, the compiler) that the
patch is needed for.</p></li>
</ul></div>
<p>In all other cases, the patch should be commented so that any
developer who knows the code of the application can make some use of
the patch. Special care should be taken for the upstream developers,
since we generally want that they accept our patches, so we have less
work in the future.</p>
</div>
<div class="sect2" lang="en">
<div class="titlepage"><div><div><h3 class="title">
<a name="components.patches.caveats"></a>11.3.2. Creating patch files</h3></div></div></div>
<p>One important thing to mention is to pay attention that no RCS
IDs get stored in the patch files, as these will cause problems when
later checked into the NetBSD CVS tree. Use the
<span class="command"><strong>pkgdiff</strong></span> command from the <a href="ftp://ftp.NetBSD.org/pub/pkgsrc/current/pkgsrc/pkgtools/pkgdiff/README.html" target="_top"><code class="filename">pkgtools/pkgdiff</code></a> package to avoid these
problems.</p>
<p>For even more automation, we recommend using
<span class="command"><strong>mkpatches</strong></span> from the same package to make a
whole set of patches. You just have to backup files before you
edit them to <code class="filename">filename.orig</code>, e.g. with
<span class="command"><strong>cp -p filename filename.orig</strong></span> or, easier, by
using <span class="command"><strong>pkgvi</strong></span> again from the same package. If
you upgrade a package this way, you can easily compare the new
set of patches with the previously existing one with
<span class="command"><strong>patchdiff</strong></span>. Copy the patches you want to use
or update from the <code class="filename">work/.newpatches</code>
directory to <code class="filename">patches/</code>.</p>
<p>When you have finished a package, remember to generate
the checksums for the patch files by using the <span class="command"><strong>make
makepatchsum</strong></span> command, see <a class="xref" href="#components.distinfo" title="11.2. distinfo">Section 11.2, “<code class="filename">distinfo</code>”</a>.</p>
<p>When adding a patch that corrects a problem in the
distfile (rather than e.g. enforcing pkgsrc's view of where
man pages should go), send the patch as a bug report to the
maintainer. This benefits non-pkgsrc users of the package,
and usually makes it possible to remove the patch in future
version.</p>
<p>The file names of the patch files are usually of the form
<code class="filename">patch-<em class="replaceable"><code>[a-z][a-z]</code></em></code>.</p>
</div>
<div class="sect2" lang="en">
<div class="titlepage"><div><div><h3 class="title">
<a name="components.patches.sources"></a>11.3.3. Sources where the patch files come from</h3></div></div></div>
<p>If you want to share patches between multiple packages
in pkgsrc, e.g. because they use the same distfiles, set
<code class="varname">PATCHDIR</code> to the path where the patch files
can be found, e.g.:</p>
<pre class="programlisting">
PATCHDIR= ${.CURDIR}/../xemacs/patches
</pre>
<p>Patch files that are distributed by the author or other
maintainers can be listed in
<code class="varname">PATCHFILES</code>.</p>
<p>If it is desired to store any patches that should not be
committed into pkgsrc, they can be kept outside the pkgsrc
tree in the <code class="filename">$LOCALPATCHES</code> directory. The
directory tree there is expected to have the same
“<span class="quote">category/package</span>” structure as pkgsrc, and
patches are expected to be stored inside these dirs (also
known as <code class="filename">$LOCALPATCHES/$PKGPATH</code>). For
example, if you want to keep a private patch for
<code class="filename">pkgsrc/graphics/png</code>, keep it in
<code class="filename">$LOCALPATCHES/graphics/png/mypatch</code>. All
files in the named directory are expected to be patch files,
and <span class="emphasis"><em>they are applied after pkgsrc patches are
applied</em></span>.</p>

<a name="components.patches.guidelines"></a>11.3.4. Patching guidelines</h3></div></div></div>
<p>When fixing a portability issue in the code do not use
preprocessor magic to check for the current operating system nor
platform. Doing so hurts portability to other platforms because
the OS-specific details are not abstracted appropriately.</p>
<p>The general rule to follow is: instead of checking for the
operating system the application is being built on, check for the
specific <span class="emphasis"><em>features</em></span> you need. For example,
instead of assuming that kqueue is available under NetBSD and
using the <code class="varname">__NetBSD__</code> macro to conditionalize
kqueue support, add a check that detects kqueue itself —
yes, this generally involves patching the
<span class="command"><strong>configure</strong></span> script. There is absolutely nothing
that prevents some OSes from adopting interfaces from other OSes
(e.g. Linux implementing kqueue), something that the above checks
cannot take into account.</p>
<p>Of course, checking for features generally involves more
work on the developer's side, but the resulting changes are
cleaner and there are chances they will work on many other
platforms. Not to mention that there are higher chances of being
later integrated into the mainstream sources. Remember:
<span class="emphasis"><em>It doesn't work unless it is right!</em></span></p>

<p>Pkgsrc consists of many <code class="filename">Makefile</code> fragments,
each of which forms a well-defined part of the pkgsrc system. Using
the <a class="citerefentry" href="http://netbsd.gw.com/cgi-bin/man-cgi?make+1+NetBSD-current"><span class="citerefentry"><span class="refentrytitle">make</span>(1)</span></a> system as a programming language for a big system
like pkgsrc requires some discipline to keep the code correct and
understandable.</p>
<p>The basic ingredients for <code class="filename">Makefile</code>
programming are variables (which are actually macros) and shell
commands. Among these shell commands may even be more complex ones
like <a class="citerefentry" href="http://netbsd.gw.com/cgi-bin/man-cgi?awk+1+NetBSD-current"><span class="citerefentry"><span class="refentrytitle">awk</span>(1)</span></a> programs. To make sure that every shell command runs
as intended it is necessary to quote all variables correctly when they
are used.</p>
<p>This chapter describes some patterns, that appear quite often in
<code class="filename">Makefile</code>s, including the pitfalls that come along
with them.</p>

<p>When you are creating a file as a

when one of the commands fails (like <a class="citerefentry" href="http://netbsd.gw.com/cgi-bin/man-cgi?false+1+NetBSD-current"><span class="citerefentry"><span class="refentrytitle">false</span>(1)</span></a> above).</p>

<a name="makefile.variables"></a>12.2. <code class="filename">Makefile</code> variables</h2></div></div></div>
<p><code class="filename">Makefile</code> variables contain strings that
can be processed using the five operators ``='', ``+='', ``?='',
``:='', and ``!='', which are described in the <a class="citerefentry" href="http://netbsd.gw.com/cgi-bin/man-cgi?make+1+NetBSD-current"><span class="citerefentry"><span class="refentrytitle">make</span>(1)</span></a> man
page.</p>
<p>When a variable's value is parsed from a
<code class="filename">Makefile</code>, the hash character ``#'' and the
backslash character ``\'' are handled specially. If a backslash is
followed by a newline, any whitespace immediately in front of the
backslash, the backslash, the newline, and any whitespace
immediately behind the newline are replaced with a single space. A
backslash character and an immediately following hash character are
replaced with a single hash character. Otherwise, the backslash is
passed as is. In a variable assignment, any hash character that is
not preceded by a backslash starts a comment that continues upto the
end of the logical line.</p>
<p><span class="emphasis"><em>Note:</em></span> Because of this parsing algorithm
the only way to create a variable consisting of a single backslash
is using the ``!='' operator, for example: <code class="varname">BACKSLASH!=echo "\\"</code>.</p>
<p>So far for defining variables. The other thing you can do with
variables is evaluating them. A variable is evaluated when it is
part of the right side of the ``:='' or the ``!='' operator, or
directly before executing a shell command which the variable is part
of. In all other cases, <a class="citerefentry" href="http://netbsd.gw.com/cgi-bin/man-cgi?make+1+NetBSD-current"><span class="citerefentry"><span class="refentrytitle">make</span>(1)</span></a> performs lazy evaluation, that
is, variables are not evaluated until there's no other way. The
``modifiers'' mentioned in the man page also evaluate the
variable.</p>
<p>Some of the modifiers split the string into words and then
operate on the words, others operate on the string as a whole. When
a string is split into words, it is split as you would expect
it from <a class="citerefentry" href="http://netbsd.gw.com/cgi-bin/man-cgi?sh+1+NetBSD-current"><span class="citerefentry"><span class="refentrytitle">sh</span>(1)</span></a>.</p>
<p>No rule without exception—the <span class="command"><strong>.for</strong></span>
loop does not follow the shell quoting rules but splits at sequences
of whitespace.</p>
<p>There are several types of variables that should be handled
differently. Strings and two types of lists.</p>
<div class="itemizedlist"><ul type="disc">
<li><p><span class="emphasis"><em>Strings</em></span> can contain arbitrary
characters. Nevertheless, you should restrict yourself to only
using printable characters. Examples are
<code class="varname">PREFIX</code> and
<code class="varname">COMMENT</code>.</p></li>
<li><p><span class="emphasis"><em>Internal lists</em></span> are lists that
are never exported to any shell command. Their elements are
separated by whitespace. Therefore, the elements themselves cannot
have embedded whitespace. Any other characters are allowed.
Internal lists can be used in <span class="command"><strong>.for</strong></span> loops.
Examples are <code class="varname">DEPENDS</code> and
<code class="varname">BUILD_DEPENDS</code>.</p></li>
<li><p><span class="emphasis"><em>External lists</em></span> are lists that
may be exported to a shell command. Their elements can contain any
characters, including whitespace. That's why they cannot be used
in <span class="command"><strong>.for</strong></span> loops. Examples are

<p>Example 1 leads to a syntax error in the shell, as the
characters are just copied.</p>
<p>Example 2 leads to a syntax error too, and if you leave out
the last " character from <code class="varname">${STRING}</code>,
<a class="citerefentry" href="http://netbsd.gw.com/cgi-bin/man-cgi?date+1+NetBSD-current"><span class="citerefentry"><span class="refentrytitle">date</span>(1)</span></a> will be executed. The <code class="varname">$HOME</code> shell
variable would be evaluated, too.</p>
<p>Example 3 outputs each space character preceded by a
backslash (or not), depending on the implementation of the
<a class="citerefentry" href="http://netbsd.gw.com/cgi-bin/man-cgi?echo+1+NetBSD-current"><span class="citerefentry"><span class="refentrytitle">echo</span>(1)</span></a> command.</p>
<p>Example 4 handles correctly every string that does not start

implementation of the <a class="citerefentry" href="http://netbsd.gw.com/cgi-bin/man-cgi?echo+1+NetBSD-current"><span class="citerefentry"><span class="refentrytitle">echo</span>(1)</span></a> command. As long as you can
guarantee that your input does not start with a dash, this form is
appropriate.</p>
<p>Example 5 handles even the case of a leading dash
correctly.</p>
<p>Example 6 also works with every string and is the
light-weight solution, since it does not involve a pipe, which has
its own problems.</p>
<p>The <code class="varname">EXT_LIST</code> does not need to be quoted
because the quoting has already been done when adding elements to
the list.</p>

no example for it.</p>

<div class="titlepage"><div><div><h3 class="title">
<a name="quoting-guideline"></a>12.3.4. Quoting guideline</h3></div></div></div>
<p>There are many possible sources of wrongly quoted variables.
This section lists some of the commonly known ones.</p>
<div class="itemizedlist"><ul type="disc">
<li>
<p>Whenever you use the value of a list, think
about what happens to leading or trailing whitespace. If the
list is a well-formed shell expression, you can apply the
<code class="varname">:M*</code> modifier to strip leading and trailing
whitespace from each word. The <code class="varname">:M</code> operator
first splits its argument according to the rules of the shell,
and then creates a new list consisting of all words that match
the shell glob expression <code class="varname">*</code>, that is: all.
One class of situations where this is needed is when adding a
variable like <code class="varname">CPPFLAGS</code> to
<code class="varname">CONFIGURE_ARGS</code>. If the configure script
invokes other configure scripts, it strips the leading and
trailing whitespace from the variable and then passes it to the
other configure scripts. But these configure scripts expect the
(child) <code class="varname">CPPFLAGS</code> variable to be the same as
the parent <code class="varname">CPPFLAGS</code>. That's why we better
pass the <code class="varname">CPPFLAGS</code> value properly trimmed. And
here is how we do it:</p>
<pre class="programlisting">
CPPFLAGS= # empty
CPPFLAGS+= -Wundef -DPREFIX=\"${PREFIX:Q}\"
CPPFLAGS+= ${MY_CPPFLAGS}
CONFIGURE_ARGS+= CPPFLAGS=${CPPFLAGS:M*:Q}
all:
echo x${CPPFLAGS:Q}x # leading and trailing whitespace
echo x${CONFIGURE_ARGS}x # properly trimmed
</pre>
</li>
<li><p>The example above contains one bug: The
<code class="varname">${PREFIX}</code> is a properly quoted shell
expression, but there is the C compiler after it, which also
expects a properly quoted string (this time in C syntax). The
version above is therefore only correct if
<code class="varname">${PREFIX}</code> does not have embedded backslashes
or double quotes. If you want to allow these, you have to add
another layer of quoting to each variable that is used as a C
string literal. You cannot use the <code class="varname">:Q</code>
operator for it, as this operator only works for the
shell.</p></li>
<li>
<p>Whenever a variable can be empty, the
<code class="varname">:Q</code> operator can have surprising results. Here
are two completely different cases which can be solved with the
same trick.</p>
<pre class="programlisting">
EMPTY= # empty
empty_test:
for i in a ${EMPTY:Q} c; do \
echo "$$i"; \
done
for_test:
.for i in a:\ a:\test.txt
echo ${i:Q}
echo "foo"
.endfor
</pre>
<p>The first example will only print two of the three lines
we might have expected. This is because
<code class="varname">${EMPTY:Q}</code> expands to the empty string, which
the shell cannot see. The workaround is to write
<code class="varname">${EMPTY:Q}""</code>. This pattern can be often found
as <code class="varname">${TEST} -z ${VAR:Q}</code> or as <code class="varname">${TEST}
-f ${FNAME:Q}</code> (both of these are wrong).</p>
<p>The second example will only print three lines instead of
four. The first line looks like <code class="varname">a:\ echo foo</code>.
This is because the backslash of the value
<code class="varname">a:\</code> is interpreted as a line-continuation by
<a class="citerefentry" href="http://netbsd.gw.com/cgi-bin/man-cgi?make+1+NetBSD-current"><span class="citerefentry"><span class="refentrytitle">make</span>(1)</span></a>, which makes the second line the arguments of the
<a class="citerefentry" href="http://netbsd.gw.com/cgi-bin/man-cgi?echo+1+NetBSD-current"><span class="citerefentry"><span class="refentrytitle">echo</span>(1)</span></a> command from the first line. To avoid this, write
<code class="varname">${i:Q}""</code>.</p>

<p>The pkgsrc bmake program does not handle the following
assignment correctly. In case <code class="varname">_othervar_</code>
contains a ``-'' character, one of the closing braces is included
in <code class="varname">${VAR}</code> after this code executes.</p>
<pre class="programlisting">
VAR:= ${VAR:N${_othervar_:C/-//}}

<p>If you have used any of the *-dirs packages, as explained in
<a class="xref" href="#faq.common-dirs" title="13.8. Sharing directories between packages">Section 13.8, “Sharing directories between packages”</a>, you may have noticed that
<span class="command"><strong>make print-PLIST</strong></span> outputs a set of
<code class="varname">@comment</code>s instead of real
<code class="varname">@dirrm</code> lines. You can also do this for
specific directories and files, so that the results of that
command are very close to reality. This helps <span class="emphasis"><em>a
lot</em></span> during the update of packages.</p>
<p>The <code class="varname">PRINT_PLIST_AWK</code> variable takes a set
of AWK patterns and actions that are used to filter the output of
print-PLIST. You can <span class="emphasis"><em>append</em></span> any chunk of AWK
scripting you like to it, but be careful with quoting.</p>
<p>For example, to get all files inside the
<code class="filename">libdata/foo</code> directory removed from the
resulting PLIST:</p>
<pre class="programlisting">
PRINT_PLIST_AWK+= /^libdata\/foo/ { next; }
</pre>
<p>And to get all the <code class="varname">@dirrm</code> lines referring
to a specific (shared) directory converted to
<code class="varname">@comment</code>s:</p>
<pre class="programlisting">
PRINT_PLIST_AWK+= /^@dirrm share\/specific/ { print "@comment " $$0; next; }

<a name="plist.misc"></a>13.4. Variable substitution in PLIST</h2></div></div></div>
<p>A number of variables are substituted automatically in
PLISTs when a package is installed on a system. This includes the
following variables:</p>
<div class="variablelist"><dl>
<dt><span class="term"><code class="varname">${MACHINE_ARCH}</code>, <code class="varname">${MACHINE_GNU_ARCH}</code></span></dt>
<dd>
<p>Some packages like emacs and perl embed information
about which architecture they were built on into the
pathnames where they install their files. To handle this
case, PLIST will be preprocessed before actually used, and
the symbol
“<span class="quote"><code class="varname">${MACHINE_ARCH}</code></span>” will be
replaced by what <span class="command"><strong>uname -p</strong></span> gives. The
same is done if the string
<code class="varname">${MACHINE_GNU_ARCH}</code> is embedded in
PLIST somewhere - use this on packages that have GNU
autoconf-created configure scripts.</p>
<div class="note" style="margin-left: 0.5in; margin-right: 0.5in;">
<h3 class="title">Legacy note</h3>
<p>There used to be a symbol
“<span class="quote"><code class="varname">$ARCH</code></span>” that
was replaced by the output of <span class="command"><strong>uname

been removed.</p>
</div>
</dd>
<dt><span class="term"><code class="varname">${OPSYS}</code>, <code class="varname">${LOWER_OPSYS}</code>, <code class="varname">${OS_VERSION}</code></span></dt>
<dd>
<p>Some packages want to embed the OS name and version
into some paths. To do this, use these variables in the
<code class="filename">PLIST</code>:
</p>
<div class="itemizedlist"><ul type="disc">
<li><p><code class="varname">${OPSYS}</code> - output of “<span class="quote"><span class="command"><strong>uname -s</strong></span></span>”</p></li>

<a name="faq.common-dirs"></a>13.8. Sharing directories between packages</h2></div></div></div>
<p>A “<span class="quote">shared directory</span>” is a directory where
multiple (and unrelated) packages install files. These
directories are problematic because you have to add special tricks
in the PLIST to conditionally remove them, or have some
centralized package handle them.</p>
<p>Within pkgsrc, you'll find both approaches. If a directory
is shared by a few unrelated packages, it's often not worth to add
an extra package to remove it. Therefore, one simply does:</p>
<pre class="programlisting">
@unexec ${RMDIR} %D/path/to/shared/directory 2>/dev/null || ${TRUE}
</pre>
<p>in the PLISTs of all affected packages, instead of the
regular "@dirrm" line.</p>
<p>However, if the directory is shared across many packages, two
different solutions are available:</p>
<div class="orderedlist"><ol type="1">
<li><p>If the packages have a common dependency, the directory
can be removed in that. For example, see
<a href="ftp://ftp.NetBSD.org/pub/pkgsrc/current/pkgsrc/textproc/scrollkeeper/README.html" target="_top"><code class="filename">textproc/scrollkeeper</code></a>, which
removes the shared directory
<code class="filename">share/omf</code>.</p></li>
<li><p>If the packages using the directory are not related at
all (they have no common dependencies), a *-dirs package is
used.</p></li>
</ol></div>
<p>From now on, we'll discuss the second solution. To get an
idea of the *-dirs packages available, issue:</p>
<pre class="programlisting">
<code class="prompt">%</code> cd .../pkgsrc
<code class="prompt">%</code> ls -d */*-dirs
</pre>
<p>Their use from other packages is very simple. The
<code class="varname">USE_DIRS</code> variable takes a list of package names
(without the “<span class="quote">-dirs</span>” part) together with the required
version number (always pick the latest one when writing new
packages).</p>
<p>For example, if a package installs files under
<code class="filename">share/applications</code>, it should have the
following line in it:</p>
<pre class="programlisting">
USE_DIRS+= xdg-1.1

print-PLIST</strong></span>, you should get the right (commented out)
lines.</p>
<p>Note that even if your package is using
<code class="filename">$X11BASE</code>, it must not depend on the
*-x11-dirs packages. Just specify the name without that part and
pkgsrc (in particular, <code class="filename">mk/dirs.mk</code>) will take
care of it.</p>

</div>
<p>Buildlink is a framework in pkgsrc that controls what headers and libraries
are seen by a package's configure and build processes. This is implemented
in a two step process:</p>
<div class="orderedlist"><ol type="1">
<li><p>Symlink headers and libraries for dependencies into
<code class="varname">BUILDLINK_DIR</code>, which by default is a subdirectory
of <code class="varname">WRKDIR</code>.</p></li>
<li><p>Create wrapper scripts that are used in place of the normal compiler
tools that translate <code class="option">-I${LOCALBASE}/include</code> and
<code class="option">-L${LOCALBASE}/lib</code> into references to
<code class="varname">BUILDLINK_DIR</code>. The wrapper scripts also make
native compiler on some operating systems look like GCC, so that
packages that expect GCC won't require modifications to build with
those native compilers.</p></li>
</ol></div>
<p>This normalizes the environment in which a package is built so that the
package may be built consistently despite what other software may be
installed. Please note that the normal system header and library paths,
e.g. <code class="filename">/usr/include</code>,
<code class="filename">/usr/lib</code>, etc., are always searched -- buildlink3 is
designed to insulate the package build from non-system-supplied
software.</p>
<div class="sect1" lang="en">
<div class="titlepage"><div><div><h2 class="title" style="clear: both">
<a name="converting-to-buildlink3"></a>14.1. Converting packages to use buildlink3</h2></div></div></div>
<p>The process of converting packages to use the buildlink3
framework (“<span class="quote">bl3ifying</span>”) is fairly straightforward.
The things to keep in mind are:</p>
<div class="orderedlist"><ol type="1">
<li><p>Ensure that the build always calls the wrapper scripts
instead of the actual toolchain. Some packages are tricky,
and the only way to know for sure is the check
<code class="filename">${WRKDIR}/.work.log</code> to see if the
wrappers are being invoked.</p></li>
<li><p>Don't override <code class="varname">PREFIX</code> from within
the package Makefile, e.g. Java VMs, standalone shells,
etc., because the code to symlink files into
<code class="filename">${BUILDLINK_DIR}</code> looks for files
relative to “<span class="quote">pkg_info -qp <em class="replaceable"><code>pkgname</code></em></span>”.
</p></li>
<li><p>Remember that <span class="emphasis"><em>only</em></span> the
<code class="filename">buildlink3.mk</code> files that you list in a
package's Makefile are added as dependencies for that package.
</p></li>
</ol></div>
<p>If a dependency on a particular package is required for its libraries and
headers, then we replace:</p>
<pre class="programlisting">
DEPENDS+= foo>=1.1.0:../../category/foo
</pre>
<p>with</p>
<pre class="programlisting">
.include "../../category/foo/buildlink3.mk"
</pre>
<p>The buildlink3.mk files usually define the required dependencies.
If you need a newer version of the dependency when using buildlink3.mk
files, then you can define it in your Makefile; for example:</p>
<pre class="programlisting">
BUILDLINK_API_DEPENDS.foo+= foo>=1.1.0
.include "../../category/foo/buildlink3.mk"
</pre>
<p>There are several <code class="filename">buildlink3.mk</code>
files in <code class="filename">pkgsrc/mk</code>
that handle special package issues:</p>
<div class="itemizedlist"><ul type="disc">
<li><p><code class="filename">bdb.buildlink3.mk</code> chooses either
the native or a pkgsrc Berkeley DB implementation based on
the values of <code class="varname">BDB_ACCEPTED</code> and

<li><p><code class="filename">krb5.buildlink3.mk</code> uses the value

adding a dependency on Heimdal or MIT-krb5 for packages that
require a Kerberos 5 implementation.</p></li>

<code class="varname">MOTIF_TYPE</code> to “<span class="quote">dt</span>”,
“<span class="quote">lesstif</span>”, or “<span class="quote">openmotif</span>” to choose
which Motif version will be used.</p></li>
<li><p><code class="filename">oss.buildlink3.mk</code> defines several
variables that may be used by packages that use the
Open Sound System (OSS) API.</p></li>
<li><p><code class="filename">pgsql.buildlink3.mk</code> will accept
either Postgres 8.0, 8.1, or 8.2, whichever is found installed. See
the file for more information.</p></li>
<li><p><code class="filename">pthread.buildlink3.mk</code> uses the value of
<code class="varname">PTHREAD_OPTS</code> and checks for native pthreads or adds
a dependency on <a href="ftp://ftp.NetBSD.org/pub/pkgsrc/current/pkgsrc/devel/pth/README.html" target="_top"><code class="filename">devel/pth</code></a> as needed.</p></li>
<li><p><code class="filename">xaw.buildlink3.mk</code> uses the value of

</pre>
<p>The header and footer manipulate
<code class="varname">BUILDLINK_DEPTH</code>, which is common across all
<code class="filename">buildlink3.mk</code> files and is used to track
at what depth we are including
<code class="filename">buildlink3.mk</code> files.</p>
<p>The first section controls if the dependency on
<em class="replaceable"><code>pkg</code></em> is added.
<code class="varname">BUILDLINK_DEPENDS</code> is the global list of
packages for which dependencies are added by
buildlink3.</p>
<p>The second section advises pkgsrc that the
<code class="filename">buildlink3.mk</code> file for
<em class="replaceable"><code>pkg</code></em> has been included at some point.
<code class="varname">BUILDLINK_PACKAGES</code> is the global list of
packages for which <code class="filename">buildlink3.mk</code> files
have been included. It must <span class="emphasis"><em>always</em></span> be
appended to within a <code class="filename">buildlink3.mk</code>
file.</p>
<p>The third section is protected from multiple inclusion
and controls how the dependency on <em class="replaceable"><code>pkg</code></em> is
added. Several important variables are set in the section:</p>
<div class="itemizedlist"><ul type="disc">
<li><p><code class="varname">BUILDLINK_API_DEPENDS.<em class="replaceable"><code>pkg</code></em></code>
is the actual dependency recorded in the installed
package; this should always be set using
<span class="command"><strong>+=</strong></span> to ensure that
we're appending to any pre-existing list of values. This
variable should be set to the first version of the
package that had an API change.
</p></li>
<li><p><code class="varname">BUILDLINK_PKGSRCDIR.<em class="replaceable"><code>pkg</code></em></code>
is the location of the <em class="replaceable"><code>pkg</code></em>
pkgsrc directory.</p></li>
<li><p><code class="varname">BUILDLINK_DEPMETHOD.<em class="replaceable"><code>pkg</code></em></code>
(not shown above) controls whether we use
<code class="varname">BUILD_DEPENDS</code> or
<code class="varname">DEPENDS</code> to add the dependency on
<em class="replaceable"><code>pkg</code></em>. The build dependency is
selected by setting
<code class="varname">BUILDLINK_DEPMETHOD.<em class="replaceable"><code>pkg</code></em></code>
to “<span class="quote">build</span>”. By default, the full dependency is
used.</p></li>
<li><p><code class="varname">BUILDLINK_INCDIRS.<em class="replaceable"><code>pkg</code></em></code>
and
<code class="varname">BUILDLINK_LIBDIRS.<em class="replaceable"><code>pkg</code></em></code>
(not shown above) are lists of subdirectories of
<code class="filename">${BUILDLINK_PREFIX.<em class="replaceable"><code>pkg</code></em>}</code>
to add to the header and library search paths. These
default to “<span class="quote">include</span>” and “<span class="quote">lib</span>”
respectively.</p></li>
<li><p><code class="varname">BUILDLINK_CPPFLAGS.<em class="replaceable"><code>pkg</code></em></code>
(not shown above) is the list of preprocessor flags to add
to <code class="varname">CPPFLAGS</code>, which are passed on to the
configure and build phases. The “<span class="quote">-I</span>” option
should be avoided and instead be handled using
<code class="varname">BUILDLINK_INCDIRS.<em class="replaceable"><code>pkg</code></em></code> as
above.</p></li>
</ul></div>
<p>The following variables are all optionally defined within
this second section (protected against multiple inclusion) and
control which package files are symlinked into
<code class="filename">${BUILDLINK_DIR}</code> and how their names are
transformed during the symlinking:</p>
<div class="itemizedlist"><ul type="disc">
<li><p><code class="varname">BUILDLINK_FILES.<em class="replaceable"><code>pkg</code></em></code>
(not shown above) is a shell glob pattern relative to
<code class="filename">${BUILDLINK_PREFIX.<em class="replaceable"><code>pkg</code></em>}</code>
to be symlinked into
<code class="filename">${BUILDLINK_DIR}</code>,
e.g. <code class="filename">include/*.h</code>.</p></li>
<li><p><code class="varname">BUILDLINK_FILES_CMD.<em class="replaceable"><code>pkg</code></em></code>
(not shown above) is a shell pipeline that
outputs to stdout a list of files relative to
<code class="filename">${BUILDLINK_PREFIX.<em class="replaceable"><code>pkg</code></em>}</code>.
The resulting files are to be symlinked
into <code class="filename">${BUILDLINK_DIR}</code>. By default,
this takes the <code class="filename">+CONTENTS</code> of a
<em class="replaceable"><code>pkg</code></em> and filters it through
<code class="varname">${BUILDLINK_CONTENTS_FILTER.<em class="replaceable"><code>pkg</code></em>}</code>.</p></li>
<li><p><code class="varname">BUILDLINK_CONTENTS_FILTER.<em class="replaceable"><code>pkg</code></em></code>
(not shown above) is a filter command that filters
<code class="filename">+CONTENTS</code> input into a list of files
relative to
<code class="filename">${BUILDLINK_PREFIX.<em class="replaceable"><code>pkg</code></em>}</code>
on stdout. By default for overwrite packages,
<code class="varname">BUILDLINK_CONTENTS_FILTER.<em class="replaceable"><code>pkg</code></em></code>
outputs the contents of the <code class="filename">include</code>
and <code class="filename">lib</code> directories in the package
<code class="filename">+CONTENTS</code>, and for pkgviews packages,
it outputs any libtool archives in
<code class="filename">lib</code> directories.</p></li>
<li><p><code class="varname">BUILDLINK_FNAME_TRANSFORM.<em class="replaceable"><code>pkg</code></em></code>
(not shown above) is a list of sed arguments used to
transform the name of the source filename into a
destination filename, e.g. <span class="command"><strong>-e
"s|/curses.h|/ncurses.h|g"</strong></span>.</p></li>
</ul></div>
<p>The last section includes any
<code class="filename">buildlink3.mk</code> needed for
<em class="replaceable"><code>pkg</code></em>'s library dependencies.
Including these <code class="filename">buildlink3.mk</code> files
means that the headers and libraries for these
dependencies are also symlinked into
<code class="filename">${BUILDLINK_DIR}</code>
whenever the <em class="replaceable"><code>pkg</code></em>
<code class="filename">buildlink3.mk</code>
file is included.</p>

<p>The situation that requires increasing the dependency listed in
<code class="varname">BUILDLINK_API_DEPENDS.<em class="replaceable"><code>pkg</code></em></code>
after a package update is when the API or interface to the
header files change.</p>
<p>In this case,
<code class="varname">BUILDLINK_API_DEPENDS.<em class="replaceable"><code>pkg</code></em></code>
should be adjusted to require at least the new package
version. In some cases, the packages that depend on this new
version may need their <code class="varname">PKGREVISION</code>s
increased and, if they have <code class="filename">buildlink3.mk</code>
files, their
<code class="varname">BUILDLINK_API_DEPENDS.<em class="replaceable"><code>pkg</code></em></code>
adjusted, too. This is needed so pkgsrc will require the
correct package dependency and not settle for an older one
when building the source.</p>
<p><code class="varname">BUILDLINK_ABI_DEPENDS.<em class="replaceable"><code>pkg</code></em></code>
should be increased when the binary interface or sonames
(major number of the library version) of any installed
shared libraries change. This is needed so that binary
packages made using it will require the correct package
dependency and not settle for an older one which will not
contain the necessary shared libraries.</p>
<p>See <a class="xref" href="#dependencies" title="19.1.6. Handling dependencies">Section 19.1.6, “Handling dependencies”</a> for
more information about dependencies on other packages,
including the <code class="varname">BUILDLINK_ABI_DEPENDS</code> and
<code class="varname">ABI_DEPENDS</code> definitions.</p>
<p>Please take careful consideration before adjusting
<code class="varname">BUILDLINK_API_DEPENDS.<em class="replaceable"><code>pkg</code></em></code>
or
<code class="varname">BUILDLINK_ABI_DEPENDS.<em class="replaceable"><code>pkg</code></em></code>
as we don't want to cause unneeded package deletions and
rebuilds. In many cases, new versions of packages work just
fine with older dependencies.</p>
<p>Also it is not needed to set
<code class="varname">BUILDLINK_ABI_DEPENDS.<em class="replaceable"><code>pkg</code></em></code>
when it is identical to
<code class="varname">BUILDLINK_API_DEPENDS.<em class="replaceable"><code>pkg</code></em></code>. </p>

</pre>
<p>The first section sets
<code class="varname">IS_BUILTIN.<em class="replaceable"><code>pkg</code></em></code>
depending on if <em class="replaceable"><code>pkg</code></em> really exists
in the base system. This should not be a base system software
with similar functionality to <em class="replaceable"><code>pkg</code></em>;
it should only be “<span class="quote">yes</span>” if the actual package is
included as part of the base system. This variable is only
used internally within the <code class="filename">builtin.mk</code>
file.</p>
<p>The second section sets
<code class="varname">BUILTIN_PKG.<em class="replaceable"><code>pkg</code></em></code>
to the version of <em class="replaceable"><code>pkg</code></em> in the base
system if it exists (if
<code class="varname">IS_BUILTIN.<em class="replaceable"><code>pkg</code></em></code>
is “<span class="quote">yes</span>”). This variable is only used internally
within the <code class="filename">builtin.mk</code> file.</p>
<p>The third section sets
<code class="varname">USE_BUILTIN.<em class="replaceable"><code>pkg</code></em></code>
and is <span class="emphasis"><em>required</em></span> in all
<code class="filename">builtin.mk</code> files. The code in this
section must make the determination whether the built-in
software is adequate to satisfy the dependencies listed in
<code class="varname">BUILDLINK_API_DEPENDS.<em class="replaceable"><code>pkg</code></em></code>.
This is typically done by comparing
<code class="varname">BUILTIN_PKG.<em class="replaceable"><code>pkg</code></em></code>
against each of the dependencies in
<code class="varname">BUILDLINK_API_DEPENDS.<em class="replaceable"><code>pkg</code></em></code>.
<code class="varname">USE_BUILTIN.<em class="replaceable"><code>pkg</code></em></code>

may be “<span class="quote">yes</span>” even if
<code class="varname">IS_BUILTIN.<em class="replaceable"><code>pkg</code></em></code>

<p>The last section is guarded by
<code class="varname">CHECK_BUILTIN.<em class="replaceable"><code>pkg</code></em></code>,

<a name="native-or-pkgsrc-preference"></a>14.3.2. Global preferences for native or pkgsrc software</h3></div></div></div>
<p>When building packages, it's possible to choose whether to set
a global preference for using either the built-in (native)
version or the pkgsrc version of software to satisfy a
dependency. This is controlled by setting
<code class="varname">PREFER_PKGSRC</code> and
<code class="varname">PREFER_NATIVE</code>. These variables take values
of either “<span class="quote">yes</span>”, “<span class="quote">no</span>”, or a list of

use the pkgsrc versions of software, while
<code class="varname">PREFER_NATIVE</code> tells pkgsrc to use the
built-in versions. Preferences are determined by the most
specific instance of the package in either
<code class="varname">PREFER_PKGSRC</code> or
<code class="varname">PREFER_NATIVE</code>. If a package is specified
in neither or in both variables, then
<code class="varname">PREFER_PKGSRC</code> has precedence over

<p>This chapter describes the framework known as
<code class="literal">pkginstall</code>, whose key features are:</p>
<div class="itemizedlist"><ul type="disc">
<li><p>Generic installation and manipulation of directories and files
outside the pkgsrc-handled tree, <code class="varname">LOCALBASE</code>.</p></li>
<li><p>Automatic handling of configuration files during installation,
provided that packages are correctly designed.</p></li>
<li><p>Generation and installation of system startup scripts.</p></li>
<li><p>Registration of system users and groups.</p></li>
<li><p>Registration of system shells.</p></li>
<li><p>Automatic updating of fonts databases.</p></li>
</ul></div>
<p>The following sections inspect each of the above points in detail.</p>
<p>You may be thinking that many of the things described here could be
easily done with simple code in the package's post-installation target
(<code class="literal">post-install</code>). <span class="emphasis"><em>This is incorrect</em></span>,
as the code in them is only executed when building from source. Machines
using binary packages could not benefit from it at all (as the code itself
could be unavailable). Therefore, the only way to achieve any of the items
described above is by means of the installation scripts, which are
automatically generated by pkginstall.</p>
<div class="sect1" lang="en">
<div class="titlepage"><div><div><h2 class="title" style="clear: both">
<a name="files-and-dirs-outside-prefix"></a>15.1. Files and directories outside the installation prefix</h2></div></div></div>
<p>As you already know, the <code class="filename">PLIST</code> file holds a list
of files and directories that belong to a package. The names used in it
are relative to the installation prefix (<code class="filename">${PREFIX}</code>),
which means that it cannot register files outside this directory (absolute
path names are not allowed). Despite this restriction, some packages need
to install files outside this location; e.g., under
<code class="filename">${VARBASE}</code> or
<code class="filename">${PKG_SYSCONFDIR}</code>. The only way to achieve this
is to create such files during installation time by using
installation scripts.</p>
<p>The generic installation scripts are shell scripts that can
contain arbitrary code. The list of scripts to execute is taken from
the <code class="varname">INSTALL_FILE</code> variable, which defaults to
<code class="filename">INSTALL</code>. A similar variable exists for package
removal (<code class="varname">DEINSTALL_FILE</code>, whose default is
<code class="filename">DEINSTALL</code>). These scripts can run arbitrary
commands, so they have the potential to create and manage files
anywhere in the file system.</p>
<p>Using these general installation files is not recommended, but
may be needed in some special cases. One reason for avoiding them is
that the user has to trust the packager that there is no unwanted or
simply erroneous code included in the installation script. Also,
previously there were many similar scripts for the same functionality,
and fixing a common error involved finding and changing all of
them.</p>
<p>The pkginstall framework offers another, standardized way. It
provides generic scripts to abstract the manipulation of such files
and directories based on variables set in the package's
<code class="filename">Makefile</code>. The rest of this section describes
these variables.</p>
<div class="sect2" lang="en">
<div class="titlepage"><div><div><h3 class="title">
<a name="dirs-outside-prefix"></a>15.1.1. Directory manipulation</h3></div></div></div>
<p>The following variables can be set to request the creation of
directories anywhere in the file system:</p>
<div class="itemizedlist"><ul type="disc">
<li><p><code class="varname">MAKE_DIRS</code> and <code class="varname">OWN_DIRS</code>
contain a list of directories that should be created and should attempt
to be destroyed by the installation scripts. The difference between
the two is that the latter prompts the administrator to remove any
directories that may be left after deinstallation (because they were
not empty), while the former does not.</p></li>
<li>
<p><code class="varname">MAKE_DIRS_PERMS</code> and
<code class="varname">OWN_DIRS_PERMS</code> contain a list of tuples describing
which directories should be created and should attempt to be destroyed
by the installation scripts. Each tuple holds the following values,
separated by spaces: the directory name, its owner, its group and its
numerical mode. For example:</p>
<pre class="programlisting">
MAKE_DIRS_PERMS+= ${VARBASE}/foo/private ${ROOT_USER} ${ROOT_GROUP} 0700
</pre>
<p>The difference between the two is exactly the same as their
non-<code class="varname">PERMS</code> counterparts.</p>

<div class="sect2" lang="en">
<div class="titlepage"><div><div><h3 class="title">
<a name="files-outside-prefix"></a>15.1.2. File manipulation</h3></div></div></div>
<p>Creating non-empty files outside the installation prefix is tricky
because the <code class="filename">PLIST</code> forces all files to be inside it.
To overcome this problem, the only solution is to extract the file in the
known place (i.e., inside the installation prefix) and copy it to the
appropriate location during installation (done by the installation scripts
generated by pkginstall). We will call the former the <span class="emphasis"><em>master
file</em></span> in the following paragraphs, which describe the variables
that can be used to automatically and consistently handle files outside the
installation prefix:</p>
<div class="itemizedlist"><ul type="disc">
<li>
<p><code class="varname">CONF_FILES</code> and
<code class="varname">SUPPORT_FILES</code> are pairs of master and target files.
During installation time, the master file is copied to the target one
if and only if the latter does not exist. Upon deinstallation, the
target file is removed provided that it was not modified by the
installation.</p>
<p>The difference between the two is that the latter prompts the
administrator to remove any files that may be left after
deinstallation (because they were not empty), while the former does
not.</p>
</li>
<li>
<p><code class="varname">CONF_FILES_PERMS</code> and
<code class="varname">SUPPORT_FILES_PERMS</code> contain tuples describing master
files as well as their target locations. For each of them, it also
specifies their owner, their group and their numeric permissions, in
this order. For example:</p>
<pre class="programlisting">
SUPPORT_FILES_PERMS+= ${PREFIX}/share/somefile ${VARBASE}/somefile ${ROOT_USER} ${ROOT_GROUP} 0700
</pre>
<p>The difference between the two is exactly the same as their
non-<code class="varname">PERMS</code> counterparts.</p>

<a name="conf-files"></a>15.2. Configuration files</h2></div></div></div>
<p>Configuration files are special in the sense that they are installed
in their own specific directory, <code class="varname">PKG_SYSCONFDIR</code>, and
need special treatment during installation (most of which is automated by
pkginstall). The main concept you must bear in mind is that files marked
as configuration files are automatically copied to the right place (somewhere
inside <code class="varname">PKG_SYSCONFDIR</code>) during installation <span class="emphasis"><em>if
and only if</em></span> they didn't exist before. Similarly, they will not
be removed if they have local modifications. This ensures that
administrators never lose any custom changes they may have made.</p>
<div class="sect2" lang="en">
<div class="titlepage"><div><div><h3 class="title">
<a name="conf-files-sysconfdir"></a>15.2.1. How <code class="varname">PKG_SYSCONFDIR</code> is set</h3></div></div></div>
<p>As said before, the <code class="varname">PKG_SYSCONFDIR</code> variable
specifies where configuration files shall be installed. Its contents are
set based upon the following variables:</p>
<div class="itemizedlist"><ul type="disc">
<li><p><code class="varname">PKG_SYSCONFBASE</code>: The configuration's root
directory. Defaults to <code class="filename">${PREFIX}/etc</code> although it may
be overridden by the user to point to his preferred location (e.g.,
<code class="filename">/etc</code>, <code class="filename">/etc/pkg</code>, etc.).
Packages must not use it directly.</p></li>
<li>
<p><code class="varname">PKG_SYSCONFSUBDIR</code>: A subdirectory of
<code class="varname">PKG_SYSCONFBASE</code> under which the configuration files
for the package being built shall be installed. The definition of this
variable only makes sense in the package's
<code class="filename">Makefile</code> (i.e., it is not user-customizable).</p>
<p>As an example, consider the Apache package,
<a href="ftp://ftp.NetBSD.org/pub/pkgsrc/current/pkgsrc/www/apache2/README.html" target="_top"><code class="filename">www/apache2</code></a>, which places its
configuration files under the
<code class="filename">httpd/</code> subdirectory of
<code class="varname">PKG_SYSCONFBASE</code>. This should be set in the package
Makefile.</p>
</li>
<li><p><code class="varname">PKG_SYSCONFVAR</code>: Specifies the name of the
variable that holds this package's configuration directory (if
different from <code class="varname">PKG_SYSCONFBASE</code>). It defaults to
<code class="varname">PKGBASE</code>'s value, and is always prefixed with
<code class="literal">PKG_SYSCONFDIR</code>.</p></li>
<li><p><code class="varname">PKG_SYSCONFDIR.${PKG_SYSCONFVAR}</code>: Holds the
directory where the configuration files for the package identified by
<code class="varname">PKG_SYSCONFVAR</code>'s shall be placed.</p></li>
</ul></div>
<p>Based on the above variables, pkginstall determines the value of
<code class="varname">PKG_SYSCONFDIR</code>, which is the <span class="emphasis"><em>only</em></span>
variable that can be used within a package to refer to its configuration
directory. The algorithm used to set its value is basically the
following:</p>
<div class="orderedlist"><ol type="1">
<li><p>If <code class="varname">PKG_SYSCONFDIR.${PKG_SYSCONFVAR}</code> is set,
its value is used.</p></li>
<li><p>If the previous variable is not defined but
<code class="varname">PKG_SYSCONFSUBDIR</code> is set in the package's
<code class="filename">Makefile</code>, the resulting value is
<code class="filename">${PKG_SYSCONFBASE}/${PKG_SYSCONFSUBDIR}</code>.</p></li>
<li><p>Otherwise, it is set to
<code class="filename">${PKG_SYSCONFBASE}</code>.</p></li>
</ol></div>
<p>It is worth mentioning that <code class="filename">${PKG_SYSCONFDIR}</code> is
automatically added to <code class="filename">OWN_DIRS</code>. See <a class="xref" href="#dirs-outside-prefix" title="15.1.1. Directory manipulation">Section 15.1.1, “Directory manipulation”</a> what this means.</p>

<a name="conf-files-configure"></a>15.2.2. Telling the software where configuration files are</h3></div></div></div>
<p>Given that pkgsrc (and users!) expect configuration files to be in a
known place, you need to teach each package where it shall install its
files. In some cases you will have to patch the package Makefiles to
achieve it. If you are lucky, though, it may be as easy as passing an
extra flag to the configuration script; this is the case of GNU Autoconf-
generated files:</p>
<pre class="programlisting">
CONFIGURE_ARGS+= --sysconfdir=${PKG_SYSCONFDIR}
</pre>
<p>Note that this specifies where the package has to <span class="emphasis"><em>look
for</em></span> its configuration files, not where they will be originally
installed (although the difference is never explicit,
unfortunately).</p>
</div>
<div class="sect2" lang="en">
<div class="titlepage"><div><div><h3 class="title">
<a name="conf-files-patching"></a>15.2.3. Patching installations</h3></div></div></div>
<p>As said before, pkginstall automatically handles configuration files.
This means that <span class="strong"><strong>the packages themselves must not
touch the contents of <code class="filename">${PKG_SYSCONFDIR}</code>
directly</strong></span>. Bad news is that many software installation scripts
will, out of the box, mess with the contents of that directory. So what is
the correct procedure to fix this issue?</p>
<p>You must teach the package (usually by manually patching it) to
install any configuration files under the examples hierarchy,
<code class="filename">share/examples/${PKGBASE}/</code>. This way, the
<code class="filename">PLIST</code> registers them and the administrator always
has the original copies available.</p>
<p>Once the required configuration files are in place (i.e., under the
examples hierarchy), the pkginstall framework can use them as master copies
during the package installation to update what is in
<code class="filename">${PKG_SYSCONFDIR}</code>. To achieve this, the variables
<code class="varname">CONF_FILES</code> and <code class="varname">CONF_FILES_PERMS</code> are
used. Check out <a class="xref" href="#files-outside-prefix" title="15.1.2. File manipulation">Section 15.1.2, “File manipulation”</a> for information
about their syntax and their purpose. Here is an example, taken from the
<a href="ftp://ftp.NetBSD.org/pub/pkgsrc/current/pkgsrc/mail/mutt/README.html" target="_top"><code class="filename">mail/mutt</code></a> package:</p>
<pre class="programlisting">
EGDIR= ${PREFIX}/share/doc/mutt/samples
CONF_FILES= ${EGDIR}/Muttrc ${PKG_SYSCONFDIR}/Muttrc
</pre>
<p>Note that the <code class="varname">EGDIR</code> variable is specific to that
package and has no meaning outside it.</p>

<div class="titlepage"><div><div><h2 class="title" style="clear: both">
<a name="rcd-scripts"></a>15.3. System startup scripts</h2></div></div></div>
<p>System startup scripts are special files because they must be
installed in a place known by the underlying OS, usually outside the
installation prefix. Therefore, the same rules described in <a class="xref" href="#files-and-dirs-outside-prefix" title="15.1. Files and directories outside the installation prefix">Section 15.1, “Files and directories outside the installation prefix”</a> apply, and the same solutions
can be used. However, pkginstall provides a special mechanism to handle
these files.</p>
<p>In order to provide system startup scripts, the package has
to:</p>
<div class="orderedlist"><ol type="1">
<li><p>Store the script inside <code class="filename">${FILESDIR}</code>, with
the <code class="literal">.sh</code> suffix appended. Considering the
<a href="ftp://ftp.NetBSD.org/pub/pkgsrc/current/pkgsrc/print/cups/README.html" target="_top"><code class="filename">print/cups</code></a> package as an example, it has a
<code class="filename">cupsd.sh</code> in its files directory.</p></li>
<li>
<p>Tell pkginstall to handle it, appending the name of the script,
without its extension, to the <code class="varname">RCD_SCRIPTS</code> variable.
Continuing the previous example:</p>
<pre class="programlisting">
RCD_SCRIPTS+= cupsd
</pre>
</li>
</ol></div>
<p>Once this is done, pkginstall will do the following steps for each
script in an automated fashion:</p>
<div class="orderedlist"><ol type="1">
<li><p>Process the file found in the files directory applying all the
substitutions described in the <code class="filename">FILES_SUBST</code>
variable.</p></li>
<li><p>Copy the script from the files directory to the examples
hierarchy, <code class="filename">${PREFIX}/share/examples/rc.d/</code>. Note
that this master file must be explicitly registered in the
<code class="filename">PLIST</code>.</p></li>
<li><p>Add code to the installation scripts to copy the startup script
from the examples hierarchy into the system-wide startup scripts
directory.</p></li>
</ol></div>

<div class="titlepage"><div><div><h3 class="title">
<a name="rcd-scripts-disable"></a>15.3.1. Disabling handling of system startup scripts</h3></div></div></div>
<p>The automatic copying of config files can be toggled by setting the
environment variable <code class="varname">PKG_RCD_SCRIPTS</code> prior to package
installation. Note that the scripts will be always copied inside the
examples hierarchy, <code class="filename">${PREFIX}/share/examples/rc.d/</code>, no

<div class="titlepage"><div><div><h2 class="title" style="clear: both">
<a name="users-and-groups"></a>15.4. System users and groups</h2></div></div></div>
<p>If a package needs to create special users and/or groups during
installation, it can do so by using the pkginstall framework.</p>
<p>Users can be created by adding entries to the
<code class="varname">PKG_USERS</code> variable. Each entry has the following
syntax:</p>
<pre class="programlisting">
user:group
</pre>
<p>Further specification of user details may be done by setting
per-user variables.
<code class="varname">PKG_UID.<em class="replaceable"><code>user</code></em></code> is the
numeric UID for the user.
<code class="varname">PKG_GECOS.<em class="replaceable"><code>user</code></em></code> is the
user's description or comment.
<code class="varname">PKG_HOME.<em class="replaceable"><code>user</code></em></code> is the
user's home directory, and defaults to
<code class="filename">/nonexistent</code> if not specified.
<code class="varname">PKG_SHELL.<em class="replaceable"><code>user</code></em></code> is the
user's shell, and defaults to <code class="filename">/sbin/nologin</code> if
not specified.</p>
<p>Similarly, groups can be created by adding entries to the
<code class="varname">PKG_GROUPS</code> variable, whose syntax is:</p>
<pre class="programlisting">
group
</pre>
<p>The numeric GID of the group may be set by defining
<code class="varname">PKG_GID.<em class="replaceable"><code>group</code></em></code>.</p>
<p>If a package needs to create the users and groups at an earlier
stage, then it can set <code class="varname">USERGROUP_PHASE</code> to
either <code class="literal">configure</code> or <code class="literal">build</code> to
indicate the phase before which the users and groups are created. In
this case, the numeric UIDs and GIDs of the created users and groups
are automatically hardcoded into the final installation scripts.</p>

<div class="titlepage"><div><div><h2 class="title" style="clear: both">
<a name="shells"></a>15.5. System shells</h2></div></div></div>
<p>Packages that install system shells should register them in the shell
database, <code class="filename">/etc/shells</code>, to make things easier to the
administrator. This must be done from the installation scripts to keep
binary packages working on any system. pkginstall provides an easy way to
accomplish this task.</p>
<p>When a package provides a shell interpreter, it has to set the
<code class="varname">PKG_SHELL</code> variable to its absolute file name. This will
add some hooks to the installation scripts to handle it. Consider the
following example, taken from <a href="ftp://ftp.NetBSD.org/pub/pkgsrc/current/pkgsrc/shells/zsh/README.html" target="_top"><code class="filename">shells/zsh</code></a>:</p>

<p>Packages that install X11 fonts should update the database files
that index the fonts within each fonts directory. This can easily be
accomplished within the pkginstall framework.</p>
<p>When a package installs X11 fonts, it must list the directories in
which fonts are installed in the
<code class="varname">FONTS_DIRS.<em class="replaceable"><code>type</code></em></code> variables,
where <em class="replaceable"><code>type</code></em> can be one of “<span class="quote">ttf</span>”,
“<span class="quote">type1</span>” or “<span class="quote">x11</span>”. This will add hooks to the
installation scripts to run the appropriate commands to update the fonts
database files within each of those directories. For convenience, if the
directory path is relative, it is taken to be relative to the package's
installation prefix. Consider the following example, taken from <a href="ftp://ftp.NetBSD.org/pub/pkgsrc/current/pkgsrc/fonts/dbz-ttf/README.html" target="_top"><code class="filename">fonts/dbz-ttf</code></a>:</p>

</div>
<p>Many packages have the ability to be built to support different
sets of features. <code class="filename">bsd.options.mk</code> is a framework
in pkgsrc that provides generic handling of those options that
determine different ways in which the packages can be built. It's
possible for the user to specify exactly which sets of options will be
built into a package or to allow a set of global default options
apply.</p>
<p>There are two broad classes of behaviors that one might want to
control via options. One is whether some particular feature is
enabled in a program that will be built anyway, often by including or
not including a dependency on some other package. The other is
whether or not an additional program will be built as part of the
package. Generally, it is better to make a split package for such
additional programs instead of using options, because it enables
binary packages to be built which can then be added separately. For
example, the foo package might have minimal dependencies (those
packages without which foo doesn't make sense), and then the foo-gfoo
package might include the GTK frontend program gfoo. This is better
than including a gtk option to foo that adds gfoo, because either that
option is default, in which case binary users can't get foo without
gfoo, or not default, in which case they can't get gfoo. With split
packages, they can install foo without having GTK, and later decide to
install gfoo (pulling in GTK at that time). This is an advantage to
source users too, avoiding the need for rebuilds.</p>
<p>Plugins with widely varying dependencies should usually be split
instead of options.</p>
<p>It is often more work to maintain split packages, especially if
the upstream package does not support this. The decision of split
vs. option should be made based on the likelihood that users will want
or object to the various pieces, the size of the dependencies that are
included, and the amount of work.</p>
<p>A further consideration is licensing. Non-free parts, or parts
that depend on non-free dependencies (especially plugins) should
almost always be split if feasible.</p>

</ol></div>
<p>A package should never modify
<code class="varname">PKG_DEFAULT_OPTIONS</code> or the variable named in
<code class="varname">PKG_OPTIONS_VAR</code>. These are strictly user-settable.
To suggest a default set of options, use
<code class="varname">PKG_SUGGESTED_OPTIONS</code>.</p>
<p><code class="varname">PKG_OPTIONS_VAR</code> must be defined before
including <code class="filename">bsd.options.mk</code>. If none of
<code class="varname">PKG_SUPPORTED_OPTIONS</code>,
<code class="varname">PKG_OPTIONS_OPTIONAL_GROUPS</code>, and
<code class="varname">PKG_OPTIONS_REQUIRED_GROUPS</code> are defined (as can
happen with platform-specific options if none of them is supported on
the current platform), <code class="varname">PKG_OPTIONS</code> is set to the
empty list and the package is otherwise treated as not using the
options framework.</p>
<p>After the inclusion of <code class="filename">bsd.options.mk</code>, the
variable <code class="varname">PKG_OPTIONS</code> contains the list of selected
build options, properly filtered to remove unsupported and duplicate
options.</p>
<p>The remaining sections contain the logic that is specific to
each option. The correct way to check for an option is to check
whether it is listed in <code class="varname">PKG_OPTIONS</code>:</p>

<p>Options that enable similar features in different packages (like
optional support for a library) should use a common name in all
packages that support it (like the name of the library). If another
package already has an option with the same meaning, use the same
name.</p>
<p>Options that enable features specific to one package, where it's
unlikely that another (unrelated) package has the same (or a similar)
optional feature, should use a name prefixed with
<code class="varname"><em class="replaceable"><code>pkgname</code></em>-</code>.</p>
<p>If a group of related packages share an optional feature
specific to that group, prefix it with the name of the
“<span class="quote">main</span>” package
(e. g. <code class="varname">djbware-errno-hack</code>).</p>
<p>For new options, add a line to
<code class="filename">mk/defaults/options.description</code>. Lines have two
fields, separated by tab. The first field is the option name, the
second its description. The description should be a whole sentence
(starting with an uppercase letter and ending with a period) that
describes what enabling the option does. E. g. “<span class="quote">Enable ispell
support.</span>” The file is sorted by option names.</p>

<p>When writing <a class="link" href="#buildlink3.mk"><code class="filename">buildlink3.mk</code></a> files, it is often necessary to list
different dependencies based on the options with which the package was
built. For querying these options, the file
<code class="filename">pkgsrc/mk/pkg-build-options.mk</code> should be used. A
typical example looks like this:</p>
<pre class="programlisting">

.if !empty(PKG_BUILD_OPTIONS.libpurple:Mdbus)

.endif
</pre>
<p>Including <code class="filename">pkg-build-options.mk</code> here will set
the variable <code class="varname">PKG_BUILD_OPTIONS.libpurple</code> to the build
options of the libpurple package, which can then be queried like
<code class="varname">PKG_OPTIONS</code> in the <code class="filename">options.mk</code>
file. See the file <code class="filename">pkg-build-options.mk</code> for more

<a name="build.intro"></a>17.1. Introduction</h2></div></div></div>
<p>This chapter gives a detailed description on how a package is
built. Building a package is separated into different
<span class="emphasis"><em>phases</em></span> (for example <code class="varname">fetch</code>,
<code class="varname">build</code>, <code class="varname">install</code>), all of which are
described in the following sections. Each phase is splitted into
so-called <span class="emphasis"><em>stages</em></span>, which take the name of the
containing phase, prefixed by one of <code class="varname">pre-</code>,
<code class="varname">do-</code> or <code class="varname">post-</code>. (Examples are
<code class="varname">pre-configure</code>, <code class="varname">post-build</code>.) Most
of the actual work is done in the <code class="varname">do-*</code> stages.</p>
<p>Never override the regular targets (like
<code class="varname">fetch</code>), if you have to, override the
<code class="varname">do-*</code> ones instead.</p>
<p>The basic steps for building a program are always the same. First
the program's source (<span class="emphasis"><em>distfile</em></span>) must be brought to
the local system and then extracted. After any pkgsrc-specific patches
to compile properly are applied, the software can be configured, then
built (usually by compiling), and finally the generated binaries, etc.
can be put into place on the system.</p>
<p>To get more details about what is happening at each step,
you can set the <code class="varname">PKG_VERBOSE</code> variable, or the
<code class="varname">PATCH_DEBUG</code> variable if you are just interested
in more details about the <span class="emphasis"><em>patch</em></span> step.</p>
</div>
<div class="sect1" lang="en">
<div class="titlepage"><div><div><h2 class="title" style="clear: both">
<a name="build.prefix"></a>17.2. Program location</h2></div></div></div>
<p>Before outlining the process performed by the NetBSD package system in
the next section, here's a brief discussion on where programs are
installed, and which variables influence this.</p>
<p>The automatic variable <code class="varname">PREFIX</code> indicates
where all files of the final program shall be installed. It is
usually set to <code class="varname">LOCALBASE</code>
(<code class="filename">/usr/pkg</code>), or <code class="varname">CROSSBASE</code>
for pkgs in the <code class="filename">cross</code> category. The value of
<code class="varname">PREFIX</code> needs to be put
into the various places in the program's source where paths to
these files are encoded. See <a class="xref" href="#components.patches" title="11.3. patches/*">Section 11.3, “patches/*”</a> and <a class="xref" href="#fixes.libtool" title="19.3.1. Shared libraries - libtool">Section 19.3.1, “Shared libraries - libtool”</a> for more details.</p>
<p>When choosing which of these variables to use,
follow the following rules:</p>
<div class="itemizedlist"><ul type="disc">
<li><p><code class="varname">PREFIX</code> always points to the location
where the current pkg will be installed. When referring to a
pkg's own installation path, use
“<span class="quote">${PREFIX}</span>”.</p></li>
<li><p><code class="varname">LOCALBASE</code> is where all non-X11 pkgs
are installed. If you need to construct a -I or -L argument
to the compiler to find includes and libraries installed by
another non-X11 pkg, use “<span class="quote">${LOCALBASE}</span>”. The name
<code class="varname">LOCALBASE</code> stems from FreeBSD, which
installed all packages in <code class="filename">/usr/local</code>. As
pkgsrc leaves <code class="filename">/usr/local</code> for the system
administrator, this variable is a misnomer.</p></li>
<li><p><code class="varname">X11BASE</code> is where the actual X11
distribution (from xsrc, etc.) is installed. When looking for
<span class="emphasis"><em>standard</em></span> X11 includes (not those
installed by a package), use “<span class="quote">${X11BASE}</span>”.</p></li>
<li>
<p>X11-based packages are special in that they may be
installed in either <code class="varname">X11BASE</code> or
<code class="varname">LOCALBASE</code>.</p>
<p>Usually, X11 packages should be installed under
<code class="varname">LOCALBASE</code> whenever possible. Note that you
will need to include
<code class="filename">../../mk/x11.buildlink3.mk</code> in them to
request the presence of X11 and to get the right compilation
flags.</p>
<p>Even though, there are some packages that cannot be installed
under <code class="varname">LOCALBASE</code>: those that come with app-defaults
files. These packages are special and they must be placed under
<code class="varname">X11BASE</code>. To accomplish this, set either
<code class="varname">USE_X11BASE</code> or <code class="varname">USE_IMAKE</code> in
your package.</p>
<p>Some notes: If you need
to find includes or libraries installed by a pkg that has
<code class="varname">USE_IMAKE</code> or <code class="varname">USE_X11BASE</code> in
its pkg <code class="filename">Makefile</code>, you need to look in
<span class="emphasis"><em>both</em></span> <code class="filename">${X11BASE}</code> and
<code class="filename">${LOCALBASE}</code>. To force installation of
all X11 packages in <code class="varname">LOCALBASE</code>, the
<a href="ftp://ftp.NetBSD.org/pub/pkgsrc/current/pkgsrc/pkgtools/xpkgwedge/README.html" target="_top"><code class="filename">pkgtools/xpkgwedge</code></a> package
is enabled by default.</p>
</li>
<li><p><code class="varname">X11PREFIX</code> should be used to refer to
the installed location of an X11
package. <code class="varname">X11PREFIX</code> will be set to
<code class="varname">X11BASE</code> if xpkgwedge is not installed, and
to <code class="varname">LOCALBASE</code> if xpkgwedge is
installed.</p></li>
<li>
<p>If xpkgwedge is installed, it is possible to have some
packages installed in <code class="varname">X11BASE</code> and some in
<code class="varname">LOCALBASE</code>. To determine the prefix of an
installed package, the <code class="varname">EVAL_PREFIX</code>
definition can be used. It takes pairs in the format
“<span class="quote">DIRNAME=<package></span>”, and the <a class="citerefentry" href="http://netbsd.gw.com/cgi-bin/man-cgi?make+1+NetBSD-current"><span class="citerefentry"><span class="refentrytitle">make</span>(1)</span></a>
variable <code class="varname">DIRNAME</code> will be set to the prefix
of the installed package <package>, or
“<span class="quote">${X11PREFIX}</span>” if the package is not
installed.</p>
<p>This is best illustrated by example.</p>
<p>The following lines are taken from
<code class="filename">pkgsrc/wm/scwm/Makefile</code>:</p>
<pre class="programlisting">
EVAL_PREFIX+= GTKDIR=gtk+
CONFIGURE_ARGS+= --with-guile-prefix=${LOCALBASE:Q}
CONFIGURE_ARGS+= --with-gtk-prefix=${GTKDIR:Q}
CONFIGURE_ARGS+= --enable-multibyte
</pre>
<p>Specific defaults can be defined for the packages
evaluated using <code class="varname">EVAL_PREFIX</code>, by using a
definition of the form:</p>
<pre class="programlisting">
GTKDIR_DEFAULT= ${LOCALBASE}
</pre>
<p>where <code class="varname">GTKDIR</code> corresponds
to the first definition in
the <code class="varname">EVAL_PREFIX</code> pair.</p>
</li>
<li><p>Within <code class="filename">${PREFIX}</code>, packages should
install files according to <a class="citerefentry" href="http://netbsd.gw.com/cgi-bin/man-cgi?hier+7+NetBSD-current"><span class="citerefentry"><span class="refentrytitle">hier</span>(7)</span></a>, with the exception that
manual pages go into <code class="filename">${PREFIX}/man</code>, not
<code class="filename">${PREFIX}/share/man</code>.</p></li>

<a name="build.builddirs"></a>17.3. Directories used during the build process</h2></div></div></div>
<p>When building a package, a number of directories is used to store
source files, temporary files, pkgsrc-internal files, and so on. These
directories are explained here.</p>
<p>Some of the directory variables contain relative pathnames. There
are two common base directories for these relative directories:
<code class="varname">PKGSRCDIR/PKGPATH</code> is used for directories that are
pkgsrc-specific. <code class="varname">WRKSRC</code> is used for directories
inside the package itself.</p>
<div class="variablelist"><dl>
<dt><span class="term"><code class="varname">PKGSRCDIR</code></span></dt>
<dd><p>This is an absolute pathname that points to the pkgsrc
root directory. Generally, you don't need
it.</p></dd>
<dt><span class="term"><code class="varname">PKGDIR</code></span></dt>
<dd><p>This is an absolute pathname that points to the
current package.</p></dd>
<dt><span class="term"><code class="varname">PKGPATH</code></span></dt>

<dt><span class="term"><code class="varname">WRKDIR</code></span></dt>
<dd><p>This is an absolute pathname pointing to the directory
where all work takes place. The distfiles are extracted to this
directory. It also contains temporary directories and log files used by
the various pkgsrc frameworks, like <span class="emphasis"><em>buildlink</em></span> or
the <span class="emphasis"><em>wrappers</em></span>.</p></dd>
<dt><span class="term"><code class="varname">WRKSRC</code></span></dt>
<dd><p>This is an absolute pathname pointing to the directory
where the distfiles are extracted. It is usually a direct subdirectory
of <code class="varname">WRKDIR</code>, and often it's the only directory entry
that isn't hidden. This variable may be changed by a package
<code class="filename">Makefile</code>.</p></dd>

<a name="build.running"></a>17.4. Running a phase</h2></div></div></div>
<p>You can run a particular phase by typing <span class="command"><strong>make
phase</strong></span>, where <span class="emphasis"><em>phase</em></span> is the name of the
phase. This will automatically run all phases that are required for this
phase. The default phase is <code class="varname">build</code>, that is, when you
run <span class="command"><strong>make</strong></span> without parameters in a package directory,
the package will be built, but not installed.</p>

<a name="build.fetch"></a>17.5. The <span class="emphasis"><em>fetch</em></span> phase</h2></div></div></div>
<p>The first step in building a package is to fetch the
distribution files (distfiles) from the sites that are providing
them. This is the task of the <span class="emphasis"><em>fetch</em></span>
phase.</p>
<div class="sect2" lang="en">
<div class="titlepage"><div><div><h3 class="title">
<a name="build.fetch.what"></a>17.5.1. What to fetch and where to get it from</h3></div></div></div>
<p>In simple cases, <code class="varname">MASTER_SITES</code>
defines all URLs from where the distfile, whose name is
derived from the <code class="varname">DISTNAME</code> variable, is
fetched. The more complicated cases are described
below.</p>
<p>The variable <code class="varname">DISTFILES</code> specifies
the list of distfiles that have to be fetched. Its value
defaults to <code class="literal">${DISTNAME}${EXTRACT_SUFX}</code>,
so that most packages don't need to define it at all.
<code class="varname">EXTRACT_SUFX</code> is
<code class="literal">.tar.gz</code> by default, but can be changed
freely. Note that if your package requires additional
distfiles to the default one, you cannot just append the
additional filenames using the <code class="literal">+=</code>
operator, but you have write for example:</p>
<pre class="programlisting">
DISTFILES= ${DISTNAME}${EXTRACT_SUFX} additional-files.tar.gz
</pre>
<p>Each distfile is fetched from a list of sites, usually
<code class="varname">MASTER_SITES</code>. If the package has multiple
<code class="varname">DISTFILES</code> or multiple
<code class="varname">PATCHFILES</code> from different sites, you can
set
<code class="varname">SITES.<em class="replaceable"><code>distfile</code></em></code>
to the list of URLs where the file
<code class="filename"><em class="replaceable"><code>distfile</code></em></code>
(including the suffix) can be found.</p>
<pre class="programlisting">
DISTFILES= ${DISTNAME}${EXTRACT_SUFX}
DISTFILES+= foo-file.tar.gz
SITES.foo-file.tar.gz= \
http://www.somewhere.com/somehow/ \
http://www.somewhereelse.com/mirror/somehow/
</pre>
<p>When actually fetching the distfiles, each item from
<code class="varname">MASTER_SITES</code> or
<code class="varname">SITES.*</code> gets the name of each distfile
appended to it, without an intermediate slash. Therefore,
all site values have to end with a slash or other separator
character. This allows for example to set
<code class="varname">MASTER_SITES</code> to a URL of a CGI script
that gets the name of the distfile as a parameter. In this
case, the definition would look like:</p>
<pre class="programlisting">
MASTER_SITES= http://www.example.com/download.cgi?file=
</pre>
<p>There are some predefined values for
<code class="varname">MASTER_SITES</code>, which can be used in
packages. The names of the variables should speak for
themselves.</p>
<pre class="programlisting">
${MASTER_SITE_APACHE}

${MASTER_SITE_SUSE}
${MASTER_SITE_TEX_CTAN}
${MASTER_SITE_XCONTRIB}
${MASTER_SITE_XEMACS}
</pre>
<p>Some explanations for the less self-explaining ones:
<code class="varname">MASTER_SITE_BACKUP</code> contains backup sites
for packages that are maintained in <a class="ulink" href="ftp://ftp.NetBSD.org/pub/NetBSD/packages/distfiles/%24%7BDIST_SUBDIR%7D" target="_top">ftp://ftp.NetBSD.org/pub/NetBSD/packages/distfiles/${DIST_SUBDIR}</a>. <code class="varname">MASTER_SITE_LOCAL</code> contains local

<p>If you choose one of these predefined sites, you may
want to specify a subdirectory of that site. Since these
macros may expand to more than one actual site, you
<span class="emphasis"><em>must</em></span> use the following construct to
specify a subdirectory:</p>
<pre class="programlisting">
MASTER_SITES= ${MASTER_SITE_GNU:=subdirectory/name/}
MASTER_SITES= ${MASTER_SITE_SOURCEFORGE:=project_name/}
</pre>
<p>Note the trailing slash after the subdirectory
name.</p>

<div class="titlepage"><div><div><h3 class="title">
<a name="build.fetch.how"></a>17.5.2. How are the files fetched?</h3></div></div></div>
<p>The <span class="emphasis"><em>fetch</em></span> phase makes sure that
all the distfiles exist in a local directory
(<code class="varname">DISTDIR</code>, which can be set by the pkgsrc
user). If the files do not exist, they are fetched using
commands of the form</p>
<pre class="programlisting">

<p>When the distfiles are present on the local system, they
need to be extracted, as they usually come in the form of some
compressed archive format.</p>
<p>By default, all <code class="varname">DISTFILES</code> are
extracted. If you only need some of them, you can set the

<p>Extracting the files is usually done by a little

likely you will not need to change anything here. But if you
need, the following variables may help you:</p>
<div class="variablelist"><dl>

<dd><p>This variable can be set to

extracted.</p></dd>

<p>If the <code class="filename">extract</code> program doesn't
serve your needs, you can also override the
<code class="varname">EXTRACT_CMD</code> variable, which holds the
command used for extracting the files. This command is
executed in the <code class="filename">${WRKSRC}</code>
directory. During execution of this command, the shell
variable <code class="varname">extract_file</code> holds the absolute
pathname of the file that is going to be extracted.</p>

Makefile.</p>

<p>Most pieces of software need information on the header

automated. In most cases, a script is supplied with the

<p>If the package contains a configure script, this can be
invoked by setting <code class="varname">HAS_CONFIGURE</code> to

dependencies, comment, maintainer, and some other useful
information. Individual entries are created by running
<span class="command"><strong>make describe</strong></span> in the packages'
directories. This index file is saved as

</div>
<p>The <code class="varname">USE_TOOLS</code> definition is used both internally
by pkgsrc and also for individual packages to define what commands
are needed for building a package (like <code class="varname">BUILD_DEPENDS</code>)
or for later run-time of an installed packaged (such as
<code class="varname">DEPENDS</code>).
If the native system provides an adequate tool, then in many cases, a pkgsrc
package will not be used.</p>
<p>When building a package, the replacement tools are
made available in a directory (as symlinks or wrapper scripts)
that is early in the executable search path. Just like the buildlink
system, this helps with consistent builds.</p>
<p>A tool may be needed to help build a specific package. For example,
perl, GNU make (gmake) or yacc may be needed.</p>
<p>Also a tool may be needed, for example, because the native system's supplied
tool may be inefficient for building a package with pkgsrc.
For example, a package may need GNU awk, bison (instead of
yacc) or a better sed.</p>
<p>The tools used by a package can be listed by running
<span class="command"><strong>make show-tools</strong></span>.</p>
<div class="sect1" lang="en">
<div class="titlepage"><div><div><h2 class="title" style="clear: both">
<a name="pkgsrc-tools"></a>18.1. Tools for pkgsrc builds</h2></div></div></div>
<p>The default set of tools used by pkgsrc is defined in
<code class="filename">bsd.pkg.mk</code>. This includes standard Unix tools,
such as: <span class="command"><strong>cat</strong></span>, <span class="command"><strong>awk</strong></span>,
<span class="command"><strong>chmod</strong></span>, <span class="command"><strong>test</strong></span>, and so on.
These can be seen by running:
<span class="command"><strong>make show-var VARNAME=USE_TOOLS</strong></span>.</p>
<p>If a package needs a specific program to build
then the <code class="varname">USE_TOOLS</code> variable can be used
to define the tools needed.</p>
</div>
<div class="sect1" lang="en">
<div class="titlepage"><div><div><h2 class="title" style="clear: both">
<a name="package-tools"></a>18.2. Tools needed by packages</h2></div></div></div>
<p>In the following examples, the :pkgsrc means to use the pkgsrc version
and not the native version for a build dependency.
And the :run means that it is used for a
run-time dependencies also (and becomes a DEPENDS).
The default is a build dependency which can be set with
:build. (So in this example, it is the same as gmake:build
and pkg-config:build.)</p>
<pre class="programlisting">
USE_TOOLS+= mktemp:pkgsrc
USE_TOOLS+= gmake perl:run pkg-config
</pre>
<p>When using the tools framework, a
<code class="varname">TOOLS_PATH.foo</code> variable is defined
which contains the full path to the appropriate tool. For example,
<code class="varname">TOOLS_PATH.bash</code> could be “<span class="quote">/bin/bash</span>”
on Linux systems.</p>
<p>If you always need a pkgsrc version of the
tool at run-time, then just use <code class="varname">DEPENDS</code> instead.

<code class="filename">pkgsrc/mk/tools/tools.${OPSYS}.mk</code> which defines

<p>One appealing feature of pkgsrc is that it runs on many
different platforms. As a result, it is important to ensure,
where possible, that packages in pkgsrc are portable. This
chapter mentions some particular details you should pay

<p>The pkgsrc user can configure pkgsrc by overriding several
variables in the file pointed to by <code class="varname">MAKECONF</code>,
which is <a class="link" href="#mk.conf"><code class="filename">mk.conf</code></a> by default. When you
want to use those variables in the preprocessor directives of

<code class="literal">.for</code>), you need to include the file
<code class="filename">../../mk/bsd.prefs.mk</code> before, which in turn
loads the user preferences.</p>
<p>But note that some variables may not be completely defined
after <code class="filename">../../mk/bsd.prefs.mk</code> has been
included, as they may contain references to variables that are
not yet defined. In shell commands this is no problem, since

<p>Occasionally, packages require interaction from the user,

<div class="itemizedlist"><ul type="disc">
<li><p>When fetching the distfiles, some packages require user
interaction such as entering username/password or accepting a

<pre class="programlisting">

</pre>
<p>Multiple interactive stages can be specified:</p>
<pre class="programlisting">

<div class="titlepage"><div><div><h3 class="title">
<a name="handling-licenses"></a>19.1.4. Handling licenses</h3></div></div></div>
<p>Authors of software can choose the licence under which
software can be copied. This is due to copyright law, and reasons
for license choices are outside the scope of pkgsrc. The pkgsrc
system recognizes that there are a number of licenses which some
users may find objectionable or difficult or impossible to comply
with. The Free Software Foundation has declared some licenses
"Free", and the Open Source Initiative has a definition of "Open
Source". The pkgsrc system, as a policy choice, does not label
packages which have licenses that are Free or Open Source.
However, packages without a license meeting either of those tests
are labeled with a license tag denoting the license. Note that a
package with no license to copy trivially does not meet either the
Free or Open Source test.</p>
<p>For packages which are not Free or Open Source, pkgsrc will
not build the package unless the user has indicated to pkgsrc that
packages with that particular license may be built. Note that
this documentation avoids the term "accepted the license". The
pkgsrc system is merely providing a mechanism to avoid
accidentally building a package with a non-free license;
judgement and responsibility remain with the user. (Installation
of binary packages are not currently subject to this mechanism;
this is a bug.)</p>
<p>One might want to only install packages with a BSD license,
or the GPL, and not the other. The pkgsrc license tag mechanism
does not provide a way to do this. It might be possible to put in
tags for free licenses, and have a default
<code class="varname">ACCEPTABLE_LICENSES</code> variable value, but this is
widely viewed as having a very poor ratio of benefit to
work.</p>
<p>The license tag mechanism is intended to address
copyright-related issues surrounding building, installing and
using a package, and not to address redistribution issues (see
<code class="varname">RESTRICTED</code> and
<code class="varname">NO_SRC_ON_FTP</code>, etc.). However, the above
definition of licenses for which tags are not needed implies
that packages with redistribution restrictions should have
tags, because Free or Open Source programs do not have
redistribution restrictions.</p>
<p>Denoting that a package may be copied according to a
particular license is done by placing the license in
<code class="filename">pkgsrc/licenses</code> and setting the
<code class="varname">LICENSE</code> variable to a string identifying the
license, e.g. in <a href="ftp://ftp.NetBSD.org/pub/pkgsrc/current/pkgsrc/graphics/xv/README.html" target="_top"><code class="filename">graphics/xv</code></a>:</p>
<pre class="programlisting">
LICENSE= xv-license
</pre>
<p>When trying to build, the user will get a notice that the
package is covered by a license which has not been placed in the
<code class="varname">ACCEPTABLE_LICENSES</code> variable:</p>
<pre class="programlisting">
<code class="prompt">%</code> <strong class="userinput"><code>make</code></strong>
===> xv-3.10anb9 has an unacceptable license: xv-license.
===> To view the license, enter "/usr/bin/make show-license".
===> To indicate acceptance, add this line to your /etc/mk.conf:
===> ACCEPTABLE_LICENSES+=xv-license
*** Error code 1
</pre>
<p>The license can be viewed with <span class="command"><strong>make
show-license</strong></span>, and if the user so chooses, the line
printed above can be added to <a class="link" href="#mk.conf"><code class="filename">mk.conf</code></a> to
convey to pkgsrc that it should not in the future fail because of
that license:</p>
<pre class="programlisting">
ACCEPTABLE_LICENSES+=xv-license
</pre>
<p>When adding a package with a new license, the license text
should be added to <code class="filename">pkgsrc/licenses</code> for
displaying. A list of known licenses can be seen in this
directory.</p>
<p>When the license changes (in a way other than formatting),
please make sure that the new license has a different name (e.g.,
append the version number if it exists, or the date). Just
because a user told pkgsrc to build programs under a previous
version of a license does not mean that pkgsrc should build
programs under the new licenses. The higher-level point is that
pkgsrc does not evaluate licenses for reasonableness; the only
test is a mechanistic test of whether a particular text has been
approved by either of two bodies.</p>
<p>The use of <code class="varname">LICENSE=shareware</code>,
<code class="varname">LICENSE=no-commercial-use</code>, and similar language
is deprecated because it does not crisply refer to a particular
license text. Another problem with such usage is that it does not
enable a user to tell pkgsrc to proceed for a single package
without also telling pkgsrc to proceed for all packages with that
tag.</p>

<div class="titlepage"><div><div><h3 class="title">
<a name="restricted-packages"></a>19.1.5. Restricted packages</h3></div></div></div>
<p>Some licenses restrict how software may be re-distributed.
Because a license tag is required unless the package is Free or
Open Source, all packages with restrictions should have license
tags. By declaring the restrictions, package tools can
automatically refrain from e.g. placing binary packages on FTP
sites.</p>
<p>There are four restrictions that may be encoded, which are
the cross product of sources (distfiles) and binaries not being
placed on FTP sites and CD-ROMs. Because this is rarely the exact
language in any license, and because non-Free licenses tend to be
different from each other, pkgsrc adopts a definition of FTP and
CD-ROM. Pkgsrc uses "FTP" to mean that the source or binary file
should not be made available over the Internet at no charge.
Pkgsrc uses "CD-ROM" to mean that the source or binary may not be
made available on some kind of media, together with other source
and binary packages, and which is sold for a distribution charge.
</p>
<p>In order to encode these restrictions, the package system
defines five make variables that can be set to note these
restrictions:</p>
<div class="itemizedlist"><ul type="disc">
<li>
<p><code class="varname">RESTRICTED</code></p>
<p>This variable should be set whenever a restriction
exists (regardless of its kind). Set this variable to a
string containing the reason for the restriction. It should
be understood that those wanting to understand the restriction
will have to read the license, and perhaps seek advice of
counsel.</p>
</li>
<li>
<p><code class="varname">NO_BIN_ON_CDROM</code></p>
<p>Binaries may not be placed on CD-ROM containing other
binary packages, for which a distribution charge may be made.
In this case, set this variable to
<code class="varname">${RESTRICTED}</code>.</p>
</li>
<li>
<p><code class="varname">NO_BIN_ON_FTP</code></p>
<p>Binaries may not made available on the Internet without
charge. In this case, set this variable to
<code class="varname">${RESTRICTED}</code>. If this variable is set,
binary packages will not be included on ftp.NetBSD.org.</p>
</li>
<li>
<p><code class="varname">NO_SRC_ON_CDROM</code></p>
<p>Distfiles may not be placed on CD-ROM, together with
other distfiles, for which a fee may be charged. In this
case, set this variable to <code class="varname">${RESTRICTED}</code>.
</p>
</li>
<li>
<p><code class="varname">NO_SRC_ON_FTP</code></p>
<p>Distfiles may not made available via FTP at no charge.
In this case, set this variable to
<code class="varname">${RESTRICTED}</code>. If this variable is set,
the distfile(s) will not be mirrored on ftp.NetBSD.org.</p>
</li>
</ul></div>
<p>Please note that the use of <code class="varname">NO_PACKAGE</code>,
<code class="varname">IGNORE</code>, <code class="varname">NO_CDROM</code>, or other
generic make variables to denote restrictions is deprecated,
because they unconditionally prevent users from generating
binary packages!</p>

<div class="titlepage"><div><div><h3 class="title">
<a name="dependencies"></a>19.1.6. Handling dependencies</h3></div></div></div>
<p>Your package may depend on some other package being present
- and there are various ways of expressing this dependency.
pkgsrc supports the <code class="varname">BUILD_DEPENDS</code> and
<code class="varname">DEPENDS</code> definitions, the
<code class="varname">USE_TOOLS</code> definition, as well as dependencies
via <code class="filename">buildlink3.mk</code>, which is the preferred way
to handle dependencies, and which uses the variables named above.
See <a class="xref" href="#buildlink" title="Chapter 14. Buildlink methodology">Chapter 14, <i>Buildlink methodology</i></a> for more information.</p>
<p>The basic difference between the two variables is as
follows: The <code class="varname">DEPENDS</code> definition registers
that pre-requisite in the binary package so it will be pulled in
when the binary package is later installed, whilst the
<code class="varname">BUILD_DEPENDS</code> definition does not, marking a
dependency that is only needed for building the package.</p>
<p>This means that if you only need a package present whilst
you are building, it should be noted as a
<code class="varname">BUILD_DEPENDS</code>.</p>
<p>The format for a <code class="varname">BUILD_DEPENDS</code> and a
<code class="varname">DEPENDS</code> definition is:</p>
<pre class="programlisting">
<pre-req-package-name>:../../<category>/<pre-req-package>
</pre>
<p>Please note that the “<span class="quote">pre-req-package-name</span>”
may include any of the wildcard version numbers recognized by
<a class="citerefentry" href="http://netbsd.gw.com/cgi-bin/man-cgi?pkg_info+1+NetBSD-current"><span class="citerefentry"><span class="refentrytitle">pkg_info</span>(1)</span></a>.</p>
<div class="orderedlist"><ol type="1">
<li>
<p>If your package needs another package's binaries or
libraries to build or run, and if that package has a
<code class="filename">buildlink3.mk</code> file available, use it:</p>
<pre class="programlisting">
.include "../../graphics/jpeg/buildlink3.mk"
</pre>
</li>
<li>
<p>If your package needs to use another package to build
itself and there is no <code class="filename">buildlink3.mk</code>
file available, use the <code class="varname">BUILD_DEPENDS</code>
definition:</p>
<pre class="programlisting">
BUILD_DEPENDS+= autoconf-2.13:../../devel/autoconf
</pre>
</li>
<li>
<p>If your package needs a library with which to link and
again there is no <code class="filename">buildlink3.mk</code> file
available, this is specified using the
<code class="varname">DEPENDS</code> definition. For example:</p>
<pre class="programlisting">
DEPENDS+= xpm-3.4j:../../graphics/xpm
</pre>
<p>You can also use wildcards in package dependencies:</p>
<pre class="programlisting">
DEPENDS+= xpm-[0-9]*:../../graphics/xpm
</pre>
<p>Note that such wildcard dependencies are retained when
creating binary packages. The dependency is checked when
installing the binary package and any package which matches
the pattern will be used. Wildcard dependencies should be
used with care.</p>
<p>The “<span class="quote">-[0-9]*</span>” should be used instead of
“<span class="quote">-*</span>” to avoid potentially ambiguous matches
such as “<span class="quote">tk-postgresql</span>” matching a
“<span class="quote">tk-*</span>” <code class="varname">DEPENDS</code>.</p>
<p>Wildcards can also be used to specify that a package
will only build against a certain minimum version of a
pre-requisite:</p>
<pre class="programlisting">
DEPENDS+= tiff>=3.5.4:../../graphics/tiff
</pre>
<p>This means that the package will build against version
3.5.4 of the tiff library or newer. Such a dependency may
be warranted if, for example, the API of the library has
changed with version 3.5.4 and a package would not compile
against an earlier version of tiff.</p>
<p>Please note that such dependencies should only be
updated if a package requires a newer pre-requisite, but
not to denote recommendations such as
ABI changes that do not prevent a package from building
correctly. Such recommendations can be expressed using
<code class="varname">ABI_DEPENDS</code>:</p>
<pre class="programlisting">
ABI_DEPENDS+= tiff>=3.6.1:../../graphics/tiff
</pre>
<p>In addition to the above <code class="varname">DEPENDS</code>
line, this denotes that while a package will build against
tiff>=3.5.4, at least version 3.6.1 is recommended.
<code class="varname">ABI_DEPENDS</code> entries will be turned into
dependencies unless explicitly ignored (in which case a
warning will be printed).</p>
<p>To ignore these ABI dependency recommendations and just
use the required <code class="varname">DEPENDS</code>, set
<code class="varname">USE_ABI_DEPENDS=NO</code>. This may make
it easier and faster to update packages built using pkgsrc,
since older compatible dependencies can continue to be
used. This is useful for people who watch their rebuilds
very carefully; it is not very good as a general-purpose
hammer. If you use it, you need to be mindful of possible
ABI changes, including those from the underlying OS.</p>
<p>Packages that are built with recommendations ignored
may not be uploaded to ftp.NetBSD.org by developers and
should not be used across different systems that may have
different versions of binary packages installed.</p>

<li>
<p>If your package needs some executable to be able to run
correctly and if there's no

<a href="ftp://ftp.NetBSD.org/pub/pkgsrc/current/pkgsrc/print/lyx/README.html" target="_top"><code class="filename">print/lyx</code></a> package needs to
be able to execute the latex binary from the teTeX package

tree.</p>
<p>In this case you can set <code class="varname">CONFLICTS</code> to a

and <a href="ftp://ftp.NetBSD.org/pub/pkgsrc/current/pkgsrc/x11/Xaw-Xpm/README.html" target="_top"><code class="filename">x11/Xaw-Xpm</code></a>
install the same shared library, thus you set in

<pre class="programlisting">

should be noted with <code class="varname">NOT_FOR_PLATFORM</code>. If
the package builds and runs on a small handful of platforms,
set <code class="varname">ONLY_FOR_PLATFORM</code> instead.
Both <code class="varname">ONLY_FOR_PLATFORM</code> and
<code class="varname">NOT_FOR_PLATFORM</code> are OS triples

<p>Some packages are tightly bound to a specific version of an

backwards compatible with other versions of the OS, and should be
uploaded to a version specific directory on the FTP server. Mark
these packages by setting <code class="varname">OSVERSION_SPECIFIC</code> to
“<span class="quote">yes</span>”. This variable is not currently used by any of
the package system internals, but may be used in the

<a name="bumping-pkgrevision"></a>19.1.11. How to handle incrementing versions when fixing an existing package</h3></div></div></div>
<p>When making fixes to an existing package it can be useful
to change the version number in <code class="varname">PKGNAME</code>. To
avoid conflicting with future versions by the original author, a
“<span class="quote">nb1</span>”, “<span class="quote">nb2</span>”, ... suffix can be used
on package versions by setting <code class="varname">PKGREVISION=1</code>
(2, ...). The “<span class="quote">nb</span>” is treated like a
“<span class="quote">.</span>” by the package tools. e.g.</p>
<pre class="programlisting">
DISTNAME= foo-17.42
PKGREVISION= 9
</pre>
<p>will result in a <code class="varname">PKGNAME</code> of
“<span class="quote">foo-17.42nb9</span>”. If you want to use the original
value of <code class="varname">PKGNAME</code> without the “<span class="quote">nbX</span>”
suffix, e.g. for setting <code class="varname">DIST_SUBDIR</code>, use
<code class="varname">PKGNAME_NOREV</code>.</p>
<p>When a new release of the package is released, the
<code class="varname">PKGREVISION</code> should be removed, e.g. on a new
minor release of the above package, things should be like:</p>
<pre class="programlisting">
DISTNAME= foo-17.43
</pre>
<p><code class="varname">PKGREVISION</code> should be incremented for any
non-trivial change in the resulting binary package. Without a
<code class="varname">PKGREVISION</code> bump, someone with the previous
version installed has no way of knowing that their package is out
of date. Thus, changes without increasing
<code class="varname">PKGREVISION</code> are essentially labeled "this is so
trivial that no reasonable person would want to upgrade", and this
is the rough test for when increasing
<code class="varname">PKGREVISION</code> is appropriate. Examples of
changes that do not merit increasing
<code class="varname">PKGREVISION</code> are:</p>
<div class="itemizedlist"><ul type="disc">
<li><p>Changing <code class="varname">HOMEPAGE</code>, <code class="varname">MAINTAINER</code>,
or comments in Makefile.</p></li>
<li><p>

<a name="fixes.subst"></a>19.1.12. Substituting variable text in the package files (the SUBST framework)</h3></div></div></div>
<p>When you want to replace the same text in multiple files
or when the replacement text varies, patches alone cannot help.
This is where the SUBST framework comes in. It provides an
easy-to-use interface for replacing text in files.
Example:</p>
<pre class="programlisting">
SUBST_CLASSES+= fix-paths
SUBST_STAGE.fix-paths= pre-configure
SUBST_MESSAGE.fix-paths= Fixing absolute paths.
SUBST_FILES.fix-paths= src/*.c
SUBST_FILES.fix-paths+= scripts/*.sh
SUBST_SED.fix-paths= -e 's,"/usr/local,"${PREFIX},g'
SUBST_SED.fix-paths+= -e 's,"/var/log,"${VARBASE}/log,g'
</pre>
<p><code class="varname">SUBST_CLASSES</code> is a list of identifiers
that are used to identify the different SUBST blocks that are
defined. The SUBST framework is heavily used by pkgsrc, so it is
important to always use the <code class="literal">+=</code> operator with
this variable. Otherwise some substitutions may be
skipped.</p>
<p>The remaining variables of each SUBST block are
parameterized with the identifier from the first line
(<code class="literal">fix-paths</code> in this case.) They can be seen as
parameters to a function call.</p>
<p><code class="varname">SUBST_STAGE.*</code> specifies the stage at
which the replacement will take place. All combinations of
<code class="literal">pre-</code>, <code class="literal">do-</code> and
<code class="literal">post-</code> together with a phase name are
possible, though only few are actually used. Most commonly used
are <code class="literal">post-patch</code> and
<code class="literal">pre-configure</code>. Of these two,
<code class="literal">pre-configure</code> should be preferred because
then it is possible to run <span class="command"><strong>bmake patch</strong></span> and
have the state after applying the patches but before making any
other changes. This is especially useful when you are debugging
a package in order to create new patches for it. Similarly,
<code class="literal">post-build</code> is preferred over
<code class="literal">pre-install</code>, because the install phase should
generally be kept as simple as possible. When you use
<code class="literal">post-build</code>, you have the same files in the
working directory that will be installed later, so you can check
if the substitution has succeeded.</p>
<p><code class="varname">SUBST_MESSAGE.*</code> is an optional text
that is printed just before the substitution is done.</p>
<p><code class="varname">SUBST_FILES.*</code> is the list of shell
globbing patterns that specifies the files in which the
substitution will take place. The patterns are interpreted
relatively to the <code class="varname">WRKSRC</code> directory.</p>
<p><code class="varname">SUBST_SED.*</code> is a list of arguments to
<a class="citerefentry" href="http://netbsd.gw.com/cgi-bin/man-cgi?sed+1+NetBSD-current"><span class="citerefentry"><span class="refentrytitle">sed</span>(1)</span></a> that specify the actual substitution. Every sed
command should be prefixed with <code class="literal">-e</code>, so that
all SUBST blocks look uniform.</p>

<a name="modified-distfiles-same-name"></a>19.2.2. How to handle modified distfiles with the 'old' name</h3></div></div></div>
<p>Sometimes authors of a software package make some
modifications after the software was released, and they put up a
new distfile without changing the package's version number. If a
package is already in pkgsrc at that time, the checksum will
no longer match. The contents of the new distfile should be
compared against the old one before changing anything, to make
sure the distfile was really updated on purpose, and that
no trojan horse or so crept in.
Please mention that the distfiles were compared and what was found
in your commit message.
Then, the correct way to work around this is to
set <code class="varname">DIST_SUBDIR</code> to a unique directory name,
usually based on <code class="varname">PKGNAME_NOREV</code>. All
<code class="varname">DISTFILES</code> and
<code class="varname">PATCHFILES</code> for this package will be put in that
subdirectory of the local distfiles directory.
(See <a class="xref" href="#bumping-pkgrevision" title="19.1.11. How to handle incrementing versions when fixing an existing package">Section 19.1.11, “How to handle incrementing versions when fixing an existing package”</a> for more details.)
In case this
happens more often, <code class="varname">PKGNAME</code> can be used (thus
including the <code class="filename">nbX</code> suffix) or a date stamp
can be appended, like <code class="varname">${PKGNAME_NOREV}-YYYYMMDD</code>.
Do not forget regenerating the <code class="filename">distinfo</code> file
after that, since it contains the <code class="varname">DIST_SUBDIR</code>
path in the filenames.
Also increase the PKGREVISION if the installed package is different.
Furthermore, a mail to the package's authors seems appropriate
telling them that changing distfiles after releases without
changing the file names is not good practice.</p>

<a name="fixes.libtool"></a>19.3.1. Shared libraries - libtool</h3></div></div></div>
<p>pkgsrc supports many different machines, with different
object formats like a.out and ELF, and varying abilities to do
shared library and dynamic loading at all. To accompany this,
varying commands and options have to be passed to the
compiler, linker, etc. to get the Right Thing, which can be
pretty annoying especially if you don't have all the machines
at your hand to test things. The
<a href="ftp://ftp.NetBSD.org/pub/pkgsrc/current/pkgsrc/devel/libtool/README.html" target="_top"><code class="filename">devel/libtool</code></a> pkg
can help here, as it just “<span class="quote">knows</span>” how to build
both static and dynamic libraries from a set of source files,
thus being platform-independent.</p>
<p>Here's how to use libtool in a package in seven simple
steps:</p>
<div class="orderedlist"><ol type="1">
<li><p>Add <code class="varname">USE_LIBTOOL=yes</code> to the package
Makefile.</p></li>
<li><p>For library objects, use “<span class="quote">${LIBTOOL} --mode=compile
${CC}</span>” in place of “<span class="quote">${CC}</span>”. You could even
add it to the definition of <code class="varname">CC</code>, if only
libraries are being built in a given Makefile. This one command
will build both PIC and non-PIC library objects, so you need not
have separate shared and non-shared library rules.</p></li>
<li>
<p>For the linking of the library, remove any
“<span class="quote">ar</span>”, “<span class="quote">ranlib</span>”, and “<span class="quote">ld
-Bshareable</span>” commands, and instead use:</p>
<pre class="programlisting">
${LIBTOOL} --mode=link \
${CC} -o ${.TARGET:.a=.la} \
${OBJS:.o=.lo} \
-rpath ${PREFIX}/lib \
-version-info major:minor
</pre>
<p>Note that the library is changed to have a
<code class="filename">.la</code> extension, and the objects are
changed to have a <code class="filename">.lo</code>
extension. Change <code class="varname">OBJS</code> as
necessary. This automatically creates all of the
<code class="filename">.a</code>,
<code class="filename">.so.major.minor</code>, and ELF symlinks (if
necessary) in the build directory. Be sure to include
“<span class="quote">-version-info</span>”, especially when major and
minor are zero, as libtool will otherwise strip off the
shared library version.</p>
<p>From the libtool manual:</p>
<pre class="programlisting">
So, libtool library versions are described by three integers:
CURRENT
The most recent interface number that this library implements.
REVISION
The implementation number of the CURRENT interface.
AGE
The difference between the newest and oldest interfaces that
this library implements. In other words, the library implements
all the interface numbers in the range from number `CURRENT -
AGE' to `CURRENT'.
If two libraries have identical CURRENT and AGE numbers, then the
dynamic linker chooses the library with the greater REVISION number.
</pre>
<p>The “<span class="quote">-release</span>” option will produce
different results for a.out and ELF (excluding symlinks)
in only one case. An ELF library of the form
“<span class="quote">libfoo-release.so.<span class="emphasis"><em>x</em></span>.<span class="emphasis"><em>y</em></span></span>”
will have a symlink of
“<span class="quote">libfoo.so.<span class="emphasis"><em>x</em></span>.<span class="emphasis"><em>y</em></span></span>”
on an a.out platform. This is handled
automatically.</p>
<p>The “<span class="quote">-rpath argument</span>” is the install
directory of the library being built.</p>
<p>In the <code class="filename">PLIST</code>, include only the
<code class="filename">.la</code> file, the other files will be
added automatically.</p>
</li>
<li>
<p>When linking shared object (<code class="filename">.so</code>)
files, i.e. files that are loaded via <a class="citerefentry" href="http://netbsd.gw.com/cgi-bin/man-cgi?dlopen+3+NetBSD-current"><span class="citerefentry"><span class="refentrytitle">dlopen</span>(3)</span></a>, NOT
shared libraries, use “<span class="quote">-module
-avoid-version</span>” to prevent them getting version
tacked on.</p>
<p>The <code class="filename">PLIST</code> file gets the
<code class="filename">foo.so</code> entry.</p>
</li>
<li>
<p>When linking programs that depend on these libraries
<span class="emphasis"><em>before</em></span> they are installed, preface
the <a class="citerefentry" href="http://netbsd.gw.com/cgi-bin/man-cgi?cc+1+NetBSD-current"><span class="citerefentry"><span class="refentrytitle">cc</span>(1)</span></a> or <a class="citerefentry" href="http://netbsd.gw.com/cgi-bin/man-cgi?ld+1+NetBSD-current"><span class="citerefentry"><span class="refentrytitle">ld</span>(1)</span></a> line with “<span class="quote">${LIBTOOL}
--mode=link</span>”, and it will find the correct
libraries (static or shared), but please be aware that
libtool will not allow you to specify a relative path in
-L (such as “<span class="quote">-L../somelib</span>”), because it
expects you to change that argument to be the
<code class="filename">.la</code> file. e.g.</p>
<pre class="programlisting">
${LIBTOOL} --mode=link ${CC} -o someprog -L../somelib -lsomelib
</pre>
<p>should be changed to:</p>
<pre class="programlisting">
${LIBTOOL} --mode=link ${CC} -o <em class="replaceable"><code>someprog</code></em> <em class="replaceable"><code>../somelib/somelib.la</code></em>
</pre>
<p>and it will do the right thing with the libraries.</p>
</li>
<li>
<p>When installing libraries, preface the <a class="citerefentry" href="http://netbsd.gw.com/cgi-bin/man-cgi?install+1+NetBSD-current"><span class="citerefentry"><span class="refentrytitle">install</span>(1)</span></a>
or <a class="citerefentry" href="http://netbsd.gw.com/cgi-bin/man-cgi?cp+1+NetBSD-current"><span class="citerefentry"><span class="refentrytitle">cp</span>(1)</span></a> command with “<span class="quote">${LIBTOOL}
--mode=install</span>”, and change the library name to
<code class="filename">.la</code>. e.g.</p>
<pre class="programlisting">
${LIBTOOL} --mode=install ${BSD_INSTALL_DATA} ${SOMELIB:.a=.la} ${PREFIX}/lib
</pre>
<p>This will install the static <code class="filename">.a</code>,
shared library, any needed symlinks, and run
<a class="citerefentry" href="http://netbsd.gw.com/cgi-bin/man-cgi?ldconfig+8+NetBSD-current"><span class="citerefentry"><span class="refentrytitle">ldconfig</span>(8)</span></a>.</p>
</li>
<li><p>In your <code class="filename">PLIST</code>, include only
the <code class="filename">.la</code>
file (this is a change from previous behaviour).</p></li>

in most cases. For older libtool using packages, libtool is

<p><code class="varname">LIBTOOL_OVERRIDE</code> specifies which libtool
scripts, relative to <code class="varname">WRKSRC</code>, to override. By

<p>If you do not need <code class="filename">*.a</code> static

<p>If your package makes use of the platform-independent library
for loading dynamic shared objects, that comes with libtool
(libltdl), you should include devel/libltdl/buildlink3.mk.</p>
<p>Some packages use libtool incorrectly so that the package
may not work or build in some circumstances. Some of the more
common errors are:</p>
<div class="itemizedlist"><ul type="disc">
<li>
<p>The inclusion of a shared object (-module) as a dependent library in an

<p>If a package needs GNU autoconf or automake to be executed
to regenerate the configure script and Makefile.in makefile
templates, then they should be executed in a pre-configure
target.</p>
<p>For packages that need only autoconf:</p>
<pre class="programlisting">
AUTOCONF_REQD= 2.50 # if default version is not good enough
USE_TOOLS+= autoconf # use "autoconf213" for autoconf-2.13

pre-configure:
cd ${WRKSRC} && autoconf
...
</pre>
<p>and for packages that need automake and autoconf:</p>
<pre class="programlisting">
AUTOMAKE_REQD= 1.7.1 # if default version is not good enough
USE_TOOLS+= automake # use "automake14" for automake-1.4
...
pre-configure:
set -e; cd ${WRKSRC}; \
aclocal; autoheader; automake -a --foreign -i; autoconf
...
</pre>
<p>Packages which use GNU Automake will almost certainly
require GNU Make.</p>
<p>There are times when the configure process makes
additional changes to the generated files, which then causes
the build process to try to re-execute the automake sequence.
This is prevented by touching various files in the configure
stage. If this causes problems with your package you can set
<code class="varname">AUTOMAKE_OVERRIDE=NO</code> in the package
Makefile.</p>

<a name="fixes.build.cpp"></a>19.5.1. Compiling C and C++ code conditionally</h3></div></div></div>
<p>If a package already comes with a GNU configure script, the
preferred way to fix the build failure is to change the
configure script, not the code. In the other cases, you can
utilize the C preprocessor, which defines certain macros
depending on the operating system and hardware architecture it
compiles for. These macros can be queried using for example
<code class="varname">#if defined(__i386)</code>. Almost every operating
system, hardware architecture and compiler has its own macro.
For example, if the macros <code class="varname">__GNUC__</code>,
<code class="varname">__i386__</code> and <code class="varname">__NetBSD__</code>
are all defined, you know that you are using NetBSD on an i386
compatible CPU, and your compiler is GCC.</p>
<p>The list of the following macros for hardware and
operating system depends on the compiler that is used. For
example, if you want to conditionally compile code on Solaris,
don't use <code class="varname">__sun__</code>, as the SunPro compiler
does not define it. Use <code class="varname">__sun</code> instead.</p>

<a name="where-to-install-documentation"></a>19.6.2. Where to install documentation</h3></div></div></div>
<p>In general, documentation should be installed into
<code class="filename">${PREFIX}/share/doc/${PKGBASE}</code> or
<code class="filename">${PREFIX}/share/doc/${PKGNAME}</code> (the latter
includes the version number of the package).</p>
<p>Many modern packages using GNU autoconf allow to set the
directory where HTML documentation is installed with the
“<span class="quote">--with-html-dir</span>” option. Sometimes using this flag
is needed because otherwise the documentation ends up in
<code class="filename">${PREFIX}/share/doc/html</code> or other
places.</p>
<p>An exception to the above is that library API documentation
generated with the <a href="ftp://ftp.NetBSD.org/pub/pkgsrc/current/pkgsrc/textproc/gtk-doc/README.html" target="_top"><code class="filename">textproc/gtk-doc</code></a> tools, for use by special
browsers (devhelp) should be left at their default location, which
is <code class="filename">${PREFIX}/share/gtk-doc</code>. Such
documentation can be recognized from files ending in
<code class="filename">.devhelp</code> or <code class="filename">.devhelp2</code>.
(It is also acceptable to install such files in
<code class="filename">${PREFIX}/share/doc/${PKGBASE}</code> or
<code class="filename">${PREFIX}/share/doc/${PKGNAME}</code>; the
<code class="filename">.devhelp*</code> file must be directly in that
directory then, no additional subdirectory level is allowed in
this case. This is usually achieved by using
“<span class="quote">--with-html-dir=${PREFIX}/share/doc</span>”.
<code class="filename">${PREFIX}/share/gtk-doc</code> is preferred
though.)</p>

<p>Certain packages, most of them in the games category, install
a score file that allows all users on the system to record their
highscores. In order for this to work, the binaries need to be
installed setgid and the score files owned by the appropriate
group and/or owner (traditionally the "games" user/group). The
following variables, documented in more detail in

<p>Note that per default, setgid installation of games is
disabled; setting <code class="varname">SETGIDGAME=YES</code> will set all
the other variables accordingly.</p>
<p>A package should therefor never hard code file ownership or

<p>Perl5 modules will install into different places depending

<a name="faq.info-files"></a>19.6.7. Packages installing info files</h3></div></div></div>
<p>Some packages install info files or use the
“<span class="quote">makeinfo</span>” or “<span class="quote">install-info</span>”
commands. <code class="varname">INFO_FILES</code> should be defined in
the package Makefile so that <code class="filename">INSTALL</code> and
<code class="filename">DEINSTALL</code> scripts will be generated to
handle registration of the info files in the Info directory
file. The “<span class="quote">install-info</span>” command used for the info
files registration is either provided by the system, or by a
special purpose package automatically added as dependency if
needed.</p>
<p><code class="varname">PKGINFODIR</code> is the directory under
<code class="filename">${PREFIX}</code> where info files are primarily
located. <code class="varname">PKGINFODIR</code> defaults to
“<span class="quote">info</span>” and can be overridden by the user.</p>
<p>The info files for the package should be listed in the
package <code class="filename">PLIST</code>; however any split info files
need not be listed.</p>
<p>A package which needs the “<span class="quote">makeinfo</span>” command
at build time must add “<span class="quote">makeinfo</span>” to
<code class="varname">USE_TOOLS</code> in its Makefile. If a minimum
version of the “<span class="quote">makeinfo</span>” command is needed it
should be noted with the <code class="varname">TEXINFO_REQD</code>
variable in the package <code class="filename">Makefile</code>. By
default, a minimum version of 3.12 is required. If the system
does not provide a <span class="command"><strong>makeinfo</strong></span> command or if it
does not match the required minimum, a build dependency on the
<a href="ftp://ftp.NetBSD.org/pub/pkgsrc/current/pkgsrc/devel/gtexinfo/README.html" target="_top"><code class="filename">devel/gtexinfo</code></a> package will
be added automatically.</p>
<p>The build and installation process of the software provided
by the package should not use the
<span class="command"><strong>install-info</strong></span> command as the registration of
info files is the task of the package
<code class="filename">INSTALL</code> script, and it must use the
appropriate <span class="command"><strong>makeinfo</strong></span> command.</p>
<p>To achieve this goal, the pkgsrc infrastructure creates
overriding scripts for the <span class="command"><strong>install-info</strong></span> and
<span class="command"><strong>makeinfo</strong></span> commands in a directory listed early
in <code class="varname">PATH</code>.</p>
<p>The script overriding <span class="command"><strong>install-info</strong></span> has
no effect except the logging of a message. The script overriding
<span class="command"><strong>makeinfo</strong></span> logs a message and according to the
value of <code class="varname">TEXINFO_REQD</code> either runs the appropriate
<span class="command"><strong>makeinfo</strong></span> command or exit on error.</p>

that a package has problems.</p>
<div class="itemizedlist"><ul type="disc">
<li><p>The first way is to plainly mark it as broken. For
this, one just sets the variable <code class="varname">BROKEN</code> to the
reason why the package is broken (similar to the
<code class="varname">RESTRICTED</code> variable). A user trying to build
the package will immediately be shown this message, and the build
will not be even tried.</p></li>
<li><p>After each pkgsrc freeze period (a time when the
tree is stabilized and a new pkgsrc branch is cut), the packages
that were not building in the official branch build on the latest
NetBSD release will be marked as broken on that branch. This is
done by setting the <code class="varname">BROKEN_IN</code> variable to the
branch name (or appending the branch name to it). If a user tries
to build such a package and the build fails, the user gets a
message that says that the package was broken on the respective
branch(es).</p></li>
</ul></div>
<p>Both types of packages are removed from pkgsrc in irregular
intervals.</p>

<p>To check out all the gotchas when building a package, here are
the steps that I do in order to get a package working. Please note
this is basically the same as what was explained in the previous
sections, only with some debugging aids.</p>
<div class="itemizedlist"><ul type="disc">
<li><p>Be sure to set <code class="varname">PKG_DEVELOPER=yes</code> in <a class="link" href="#mk.conf"><code class="filename">mk.conf</code></a>.</p></li>

<p>Install <a href="ftp://ftp.NetBSD.org/pub/pkgsrc/current/pkgsrc/pkgtools/url2pkg/README.html" target="_top"><code class="filename">pkgtools/url2pkg</code></a>,
create a directory for a new package, change into it, then run
<span class="command"><strong>url2pkg</strong></span>:</p>
<pre class="screen"><code class="prompt">%</code> <strong class="userinput"><code>mkdir /usr/pkgsrc/<em class="replaceable"><code>category</code></em>/<em class="replaceable"><code>examplepkg</code></em></code></strong>

</li>
<li><p>Edit the <code class="filename">Makefile</code> as requested.</p></li>
<li><p>Fill in the <code class="filename">DESCR</code> file</p></li>
<li><p>Run <span class="command"><strong>make configure</strong></span></p></li>
<li><p>Add any dependencies glimpsed from documentation and the
configure step to the package's
<code class="filename">Makefile</code>.</p></li>
<li>
<p>Make the package compile, doing multiple rounds of</p>

<p>Doing this step as non-root user will ensure that no files
are modified that shouldn't be, especially during the build
phase. <span class="command"><strong>mkpatches</strong></span>,
<span class="command"><strong>patchdiff</strong></span> and <span class="command"><strong>pkgvi</strong></span> are

package.</p>
</li>
<li><p>Look at the <code class="filename">Makefile</code>, fix if
necessary; see <a class="xref" href="#components.Makefile" title="11.1. Makefile">Section 11.1, “<code class="filename">Makefile</code>”</a>.</p></li>
<li>
<p>Generate a <code class="filename">PLIST</code>:</p>

<p>If this reveals any files that are missing in
<code class="filename">PLIST</code>, add them.</p>
</li>
<li>
<p>Now that the <code class="filename">PLIST</code> is OK, install the
package again and make a binary package:</p>

<p>Our policy is that we accept binaries only from pkgsrc
developers to guarantee that the packages don't contain any
trojan horses etc. This is not to annoy anyone but rather to
protect our users! You're still free to put up your home-made
binary packages and tell the world where to get them. NetBSD
developers doing bulk builds and wanting to upload them please
see <a class="xref" href="#bulk-upload" title="7.3.8. Uploading results of a bulk build">Section 7.3.8, “Uploading results of a bulk build”</a>.</p>

<a name="submitting-your-package"></a>21.2. Submitting source packages (for non-NetBSD-developers)</h2></div></div></div>
<p>First, check that your package is complete, compiles and
runs well; see <a class="xref" href="#debug" title="Chapter 20. Debugging">Chapter 20, <i>Debugging</i></a> and the rest of this
document. Next, generate an uuencoded gzipped <a class="citerefentry" href="http://netbsd.gw.com/cgi-bin/man-cgi?tar+1+NetBSD-current"><span class="citerefentry"><span class="refentrytitle">tar</span>(1)</span></a>
archive that contains all files that make up the package.
Finally, send this package to the pkgsrc bug tracking system,
either with the <a class="citerefentry" href="http://netbsd.gw.com/cgi-bin/man-cgi?send-pr+1+NetBSD-current"><span class="citerefentry"><span class="refentrytitle">send-pr</span>(1)</span></a> command, or if you don't have
that, go to the web page
<a class="ulink" href="http://www.NetBSD.org/support/send-pr.html" target="_top">http://www.NetBSD.org/support/send-pr.html</a>,
which contains some instructions and a link to a form, where you
can submit packages.</p>
<p>In the form of the problem report, the category should be
“<span class="quote">pkg</span>”, the synopsis should include the package name
and version number, and the description field should contain a
short description of your package (contents of the COMMENT
variable or DESCR file are OK). The uuencoded package data should
go into the “<span class="quote">fix</span>” field.</p>
<p>If you want to submit several packages, please send a
separate PR for each one, it's easier for us to track things
that way.</p>
<p>Alternatively, you can also import new packages into
pkgsrc-wip (“<span class="quote">pkgsrc work-in-progress</span>”); see the
homepage at <a class="ulink" href="http://pkgsrc-wip.sourceforge.net/" target="_top">http://pkgsrc-wip.sourceforge.net/</a>

<a name="general-notes-for-changes"></a>21.3. General notes when adding, updating, or removing packages</h2></div></div></div>
<p>Please note all package additions, updates, moves, and
removals in <code class="filename">pkgsrc/doc/CHANGES-<em class="replaceable"><code>YYYY</code></em></code>. It's very
important to keep this file up to date and conforming to the
existing format, because it will be used by scripts to
automatically update pages on <a class="ulink" href="http://www.NetBSD.org/" target="_top">www.NetBSD.org</a> and other
sites. Additionally, check the
<code class="filename">pkgsrc/doc/TODO</code> file and remove the entry
for the package you updated or removed, in case it was mentioned
there.</p>
<p>When the <code class="varname">PKGREVISION</code> of a package is
bumped, the change should appear in
<code class="filename">pkgsrc/doc/CHANGES-<em class="replaceable"><code>YYYY</code></em></code> if it is security
related or otherwise relevant. Mass bumps that result from a
dependency being updated should not be mentioned. In all other
cases it's the developer's decision.</p>
<p>There is a make target that helps in creating proper
<code class="filename">CHANGES-<em class="replaceable"><code>YYYY</code></em></code> entries: <span class="command"><strong>make
changes-entry</strong></span>. It uses the optional <code class="varname">CTYPE</code>
and <code class="varname">NETBSD_LOGIN_NAME</code> variables. The general
usage is to first make sure that your <code class="filename">CHANGES-<em class="replaceable"><code>YYYY</code></em></code>
file is up-to-date (to avoid having to resolve conflicts later-on)
and then to <span class="command"><strong>cd</strong></span> to the package directory. For
package updates, <span class="command"><strong>make changes-entry</strong></span> is enough.
For new packages, or package moves or removals, set the
<code class="varname">CTYPE</code> variable on the command line to "Added",
"Moved", or "Removed". You can set <code class="varname">NETBSD_LOGIN_NAME</code>
in <a class="link" href="#mk.conf"><code class="filename">mk.conf</code></a> if your local login name is
not the same as your NetBSD login name. Don't forget to commit
the changes to <code class="filename">pkgsrc/doc/CHANGES-<em class="replaceable"><code>YYYY</code></em></code>!</p>

<a name="committing-importing"></a>21.4. Committing: Importing a package into CVS</h2></div></div></div>
<p>This section is only of interest for pkgsrc developers with write
access to the pkgsrc repository. Please remember that cvs
imports files relative to the current working directory, and that
the pathname that you
give the <span class="command"><strong>cvs import</strong></span> command is so that it knows where
to place the files in the repository. Newly created packages should be
imported with a vendor tag of “<span class="quote">TNF</span>” and a release tag of
“<span class="quote">pkgsrc-base</span>”, e.g:</p>
<pre class="programlisting">
<code class="prompt">$</code> cd .../pkgsrc/category/pkgname
<code class="prompt">$</code> cvs import pkgsrc/category/pkgname TNF pkgsrc-base
</pre>
<p>Remember to move the directory from which you imported out of
the way, or cvs will complain the next time you “<span class="quote">cvs
update</span>” your source tree. Also don't forget to add the new
package to the category's <code class="filename">Makefile</code>.</p>
<p>The commit message of the initial import should include part of the
<code class="filename">DESCR</code> file, so people reading the mailing lists know
what the package is/does.</p>
<p>For new packages, “<span class="quote">cvs import</span>” is preferred to “<span class="quote">cvs
add</span>” because the former gets everything with a single command,
and provides a consistent tag.</p>

<a name="updating-package"></a>21.5. Updating a package to a newer version</h2></div></div></div>
<p>Please always put a concise, appropriate and relevant summary of the
changes between old and new versions into the commit log when updating
a package. There are various reasons for this:</p>
<div class="itemizedlist"><ul type="disc">
<li><p>A URL is volatile, and can change over time. It may go away completely
or its information may be overwritten by newer information.</p></li>
<li><p>Having the change information between old and new versions in our CVS
repository is very useful for people who use either cvs or anoncvs.</p></li>
<li><p>Having the change information between old and new versions in our CVS
repository is very useful for people who read the pkgsrc-changes mailing
list, so that they can make tactical decisions about when to upgrade
the package.</p></li>
</ul></div>
<p>Please also recognize that, just because a new version of a package
has been released, it should not automatically be upgraded in the CVS
repository. We prefer to be conservative in the packages that are
included in pkgsrc - development or beta packages are not really the
best thing for most places in which pkgsrc is used. Please use your
judgement about what should go into pkgsrc, and bear in mind that
stability is to be preferred above new and possibly untested features.</p>

<p>There are many places where you can find

<div class="itemizedlist"><ul type="disc">
<li><p>The pkgsrc guide (this document) is a collection

about certain features, announcements of new parts of the pkgsrc
infrastructure and sometimes even announcements that a certain
feature has been marked as obsolete. The benefit here is that
each message has a date appended to it.</p></li>
<li><p>Many of the files in the
<code class="filename">mk/</code> directory start with a comment that
describes the purpose of the file and how it can be used by the
pkgsrc user and package authors. An easy way to find this
documentation is to run <span class="command"><strong>bmake
help</strong></span>.</p></li>
<li><p>The CVS log messages are a rich source of
information, but they tend to be highly abbreviated, especially
for actions that occur often. Some contain a detailed
description of what has changed, but they are geared towards the
other pkgsrc developers, not towards an average pkgsrc user.
They also only document <span class="emphasis"><em>changes</em></span>, so if you
don't know what has been before, these messages may not be worth
too much to you.</p></li>
<li><p>Some parts of pkgsrc are only “<span class="quote">implicitly
documented</span>”, that is the documentation exists only in the
mind of the developer who wrote the code. To get this
information, use the <span class="command"><strong>cvs annotate</strong></span> command
to see who has written it and ask on the
<code class="literal">tech-pkg</code> mailing list, so that others can
find your questions later (see above). To be sure that the
developer in charge reads the mail, you may CC him or

<p>Quoting <a class="ulink" href="http://www.gnome.org/" target="_top">GNOME's web
site</a>:</p>
<div class="blockquote"><blockquote class="blockquote"><p>The GNOME project provides two things: The GNOME desktop
environment, an intuitive and attractive desktop for users, and the
GNOME development platform, an extensive framework for building
applications that integrate into the rest of the desktop.</p></blockquote></div>
<p>pkgsrc provides a seamless way to automatically build and install
a complete GNOME environment <span class="emphasis"><em>under many different
platforms</em></span>. We can say with confidence that pkgsrc is one of
the most advanced build and packaging systems for GNOME due to its
included technologies buildlink3, the wrappers and tools framework and
automatic configuration file management. Lots of efforts are put into
achieving a completely clean deinstallation of installed software
components.</p>
<p>Given that pkgsrc is <a class="ulink" href="http://www.NetBSD.org/" target="_top">NetBSD</a>'s official packaging system,
the above also means that great efforts are put into making GNOME work
under this operating system. Recently, <a class="ulink" href="http://www.dragonflybsd.org/" target="_top">DragonFly BSD</a> also adopted
pkgsrc as its preferred packaging system, contributing lots of
portability fixes to make GNOME build and install under it.</p>
<p>This chapter is aimed at pkgsrc developers and other people
interested in helping our GNOME porting and packaging efforts. It
provides instructions on how to manage the existing packages and some
important information regarding their internals.</p>

fully-functional GNOME desktop under NetBSD and we need your help to
achieve it!</p>

<div class="sect1" lang="en">
<div class="titlepage"><div><div><h2 class="title" style="clear: both">
<a name="meta-packages"></a>23.1. Meta packages</h2></div></div></div>
<p>pkgsrc includes three GNOME-related meta packages:</p>
<div class="itemizedlist"><ul type="disc">
<li><p><a href="ftp://ftp.NetBSD.org/pub/pkgsrc/current/pkgsrc/meta-pkgs/gnome-base/README.html" target="_top"><code class="filename">meta-pkgs/gnome-base</code></a>: Provides
the core GNOME desktop environment. It only includes the necessary
bits to get it to boot correctly, although it may lack important
functionality for daily operation. The idea behind this package is
to let end users build their own configurations on top of this one,
first installing this meta package to achieve a functional setup and
then adding individual applications.</p></li>
<li><p><a href="ftp://ftp.NetBSD.org/pub/pkgsrc/current/pkgsrc/meta-pkgs/gnome/README.html" target="_top"><code class="filename">meta-pkgs/gnome</code></a>: Provides a
complete installation of the GNOME platform and desktop as defined
by the GNOME project; this is based on the components distributed in
the <code class="filename">platform/x.y/x.y.z/sources</code> and
<code class="filename">desktop/x.y/x.y.z/sources</code> directories of the
official FTP server. Developer-only tools found in those
directories are not installed unless required by some other
component to work properly. Similarly, packages from the bindings
set (<code class="filename">bindings/x.y/x.y.z/sources</code>) are not pulled
in unless required as a dependency for an end-user component. This
package "extends" <a href="ftp://ftp.NetBSD.org/pub/pkgsrc/current/pkgsrc/meta-pkgs/gnome-base/README.html" target="_top"><code class="filename">meta-pkgs/gnome-base</code></a>.</p></li>
<li><p><a href="ftp://ftp.NetBSD.org/pub/pkgsrc/current/pkgsrc/meta-pkgs/gnome-devel/README.html" target="_top"><code class="filename">meta-pkgs/gnome-devel</code></a>:
Installs all the tools required to build a GNOME component when
fetched from the CVS repository. These are required to let the
<span class="command"><strong>autogen.sh</strong></span> scripts work appropriately.</p></li>
</ul></div>
<p>In all these packages, the <code class="varname">DEPENDS</code> lines are
sorted in a way that eases updates: a package may depend on other
packages listed before it but not on any listed after it. It is very
important to keep this order to ease updates so... <span class="emphasis"><em>do not
change it to alphabetical sorting!</em></span></p>
</div>
<div class="sect1" lang="en">
<div class="titlepage"><div><div><h2 class="title" style="clear: both">
<a name="new-package"></a>23.2. Packaging a GNOME application</h2></div></div></div>
<p>Almost all GNOME applications are written in C and use a common
set of tools as their build system. Things get different with the new
bindings to other languages (such as Python), but the following will
give you a general idea on the minimum required tools:</p>
<div class="itemizedlist"><ul type="disc">
<li>
<p>Almost all GNOME applications use the GNU Autotools as their
build system. As a general rule you will need to tell this to your
package:</p>
<pre class="programlisting">
GNU_CONFIGURE=yes
USE_LIBTOOL=yes
USE_TOOLS+=gmake
</pre>
</li>
<li>
<p>If the package uses pkg-config to detect dependencies, add this
tool to the list of required utilities:</p>
<pre class="programlisting">USE_TOOLS+=pkg-config</pre>
<p>Also use <a href="ftp://ftp.NetBSD.org/pub/pkgsrc/current/pkgsrc/pkgtools/verifypc/README.html" target="_top"><code class="filename">pkgtools/verifypc</code></a> at
the end of the build process to ensure that you did not miss to
specify any dependency in your package and that the version
requirements are all correct.</p>
</li>
<li><p>If the package uses intltool, be sure to add
<code class="literal">intltool</code> to the <code class="varname">USE_TOOLS</code>
to handle dependencies and to force the package to use the latest
available version.</p></li>
<li>
<p>If the package uses gtk-doc (a documentation generation
utility), do <span class="emphasis"><em>not</em></span> add a dependency on it. The
tool is rather big and the distfile should come with pregenerated
documentation anyway; if it does not, it is a bug that you ought to
report. For such packages you should disable gtk-doc (unless it is
the default):</p>
<pre class="programlisting">CONFIGURE_ARGS+=--disable-gtk-doc</pre>
<p>The default location of installed HTML files
(<code class="filename">share/gtk-doc/<package-name></code>) is correct
and should not be changed unless the package insists on installing
them somewhere else. Otherwise programs as
<span class="command"><strong>devhelp</strong></span> will not be able to open them. You can
do that with an entry similar to:</p>
<pre class="programlisting">CONFIGURE_ARGS+=--with-html-dir=${PREFIX}/share/gtk-doc/...</pre>
</li>
</ul></div>
<p>GNOME uses multiple <span class="emphasis"><em>shared</em></span> directories and
files under the installation prefix to maintain databases. In this
context, shared means that those exact same directories and files are
used among several different packages, leading to conflicts in the
<code class="filename">PLIST</code>. pkgsrc currently includes functionality to
handle the most common cases, so you have to forget about using
<code class="literal">@unexec ${RMDIR}</code> lines in your file lists and
omitting shared files from them. If you find yourself doing those,
<span class="emphasis"><em>your package is most likely incorrect</em></span>.</p>
<p>The following table lists the common situations that result in
using shared directories or files. For each of them, the appropriate
solution is given. After applying the solution be sure to
<span class="emphasis"><em>regenerate the package's file list</em></span> with
<span class="command"><strong>make print-PLIST</strong></span> and ensure it is correct.</p>

<a name="full-update"></a>23.3. Updating GNOME to a newer version</h2></div></div></div>
<p>When seeing GNOME as a whole, there are two kinds of
updates:</p>
<div class="variablelist"><dl>
<dt><span class="term">Major update</span></dt>
<dd>
<p>Given that there is still a very long way for GNOME 3 (if it
ever appears), we consider a major update one that goes from a
<code class="literal">2.X</code> version to a <code class="literal">2.Y</code> one,
where <code class="literal">Y</code> is even and greater than
<code class="literal">X</code>. These are hard to achieve because they
introduce lots of changes in the components' code and almost all
GNOME distfiles are updated to newer versions. Some of them can
even break API and ABI compatibility with the previous major
version series. As a result, the update needs to be done all at
once to minimize breakage.</p>
<p>A major update typically consists of around 80 package
updates and the addition of some new ones.</p>
</dd>
<dt><span class="term">Minor update</span></dt>
<dd>
<p>We consider a minor update one that goes from a
<code class="literal">2.A.X</code> version to a <code class="literal">2.A.Y</code>
one where <code class="literal">Y</code> is greater than
<code class="literal">X</code>. These are easy to achieve because they do
not update all GNOME components, can be done in an incremental way
and do not break API nor ABI compatibility.</p>
<p>A minor update typically consists of around 50 package
updates, although the numbers here may vary a lot.</p>
</dd>
</dl></div>
<p>In order to update the GNOME components in pkgsrc to a new stable
release (either major or minor), the following steps should be
followed:</p>
<div class="orderedlist"><ol type="1">
<li>
<p>Get a list of all the tarballs that form the new release by
using the following commands. These will leave the full list of the
components's distfiles into the <code class="filename">list.txt</code>
file:</p>
<pre class="screen"><code class="prompt">%</code> <strong class="userinput"><code>echo ls "*.tar.bz2" | \
ftp -V ftp://ftp.gnome.org/pub/gnome/platform/x.y/x.y.z/sources/ | \
awk '{ print $9 }' >list.txt</code></strong>
<code class="prompt">%</code> <strong class="userinput"><code>echo ls "*.tar.bz2" | \
ftp -V ftp://ftp.gnome.org/pub/gnome/desktop/x.y/x.y.z/sources/ | \
awk '{ print $9 }' >>list.txt</code></strong></pre>
</li>
<li><p>Open each meta package's <code class="filename">Makefile</code> and
bump their version to the release you are updating them to. The
three meta packages should be always consistent with versioning.
Obviously remove any <code class="varname">PKGREVISION</code>s that might be
in them.</p></li>
<li>
<p>For each meta package, update all its
<code class="varname">DEPENDS</code> lines to match the latest versions as
shown by the above commands. Do <span class="emphasis"><em>not</em></span> list any
newer version (even if found in the FTP) because the meta packages
are supposed to list the exact versions that form a specific GNOME
release. Exceptions are permitted here if a newer version solves a
serious issue in the overall desktop experience; these typically
come in the form of a revision bump in pkgsrc, not in newer versions
from the developers.</p>
<p>Packages not listed in the <code class="filename">list.txt</code> file
should be updated to the latest version available (if found in
pkgsrc). This is the case, for example, of the dependencies on the
GNU Autotools in the <a href="ftp://ftp.NetBSD.org/pub/pkgsrc/current/pkgsrc/meta-pkgs/gnome-devel/README.html" target="_top"><code class="filename">meta-pkgs/gnome-devel</code></a> meta package.</p>
</li>
<li>
<p>Generate a patch from the modified meta packages and extract the
list of "new" lines. This will provide you an outline on what
packages need to be updated in pkgsrc and in what order:</p>
<pre class="screen"><code class="prompt">%</code> <strong class="userinput"><code>cvs diff -u gnome-devel gnome-base gnome | grep '^+D' >todo.txt</code></strong></pre>
</li>
<li><p>For major desktop updates it is recommended to zap all your
installed packages and start over from scratch at this point.</p></li>
<li><p>Now comes the longest step by far: iterate over the contents
of <code class="filename">todo.txt</code> and update the packages listed in
it in order. For major desktop updates none of these should be
committed until the entire set is completed because there are chances
of breaking not-yet-updated packages.</p></li>
<li><p>Once the packages are up to date and working, commit them to
the tree one by one with appropriate log messages. At the end,
commit the three meta package updates and all the corresponding
changes to the <code class="filename">doc/CHANGES-<YEAR></code> and
<a href="http://cvsweb.NetBSD.org/bsdweb.cgi/pkgsrc/doc/TODO?rev=HEAD&content-type=text/x-cvsweb-markup" target="_top"><code class="filename">pkgsrc/doc/TODO</code></a> files.</p></li>

<a name="patching"></a>23.4. Patching guidelines</h2></div></div></div>
<p>GNOME is a very big component in pkgsrc which approaches 100
packages. Please, it is very important that you always, always,
<span class="strong"><strong>always</strong></span> feed back any portability
fixes you do to a GNOME package to the mainstream developers (see <a class="xref" href="#components.patches.feedback" title="11.3.5. Feedback to the author">Section 11.3.5, “Feedback to the author”</a>). This is the only way to get
their attention on portability issues and to ensure that future versions
can be built out-of-the box on NetBSD. The less custom patches in
pkgsrc, the easier further updates are. Those developers in charge of
issuing major GNOME updates will be grateful if you do that.</p>
<p>The most common places to report bugs are the <a class="ulink" href="http://bugzilla.gnome.org/" target="_top">GNOME's Bugzilla</a> and the <a class="ulink" href="http://bugzilla.freedesktop.org/" target="_top">freedesktop.org's
Bugzilla</a>. Not all components use these to track bugs, but most
of them do. Do not be short on your reports: always provide detailed
explanations of the current failure, how it can be improved to achieve
maximum portability and, if at all possible, provide a patch against CVS
head. The more verbose you are, the higher chances of your patch being
accepted.</p>
<p>Also, please avoid using preprocessor magic to fix portability
issues. While the FreeBSD GNOME people are doing a great job in porting
GNOME to their operating system, the official GNOME sources are now
plagued by conditionals that check for <code class="varname">__FreeBSD__</code>
and similar macros. This hurts portability. Please see our patching
guidelines (<a class="xref" href="#components.patches.guidelines" title="11.3.4. Patching guidelines">Section 11.3.4, “Patching guidelines”</a>) for more
details.</p>

<p>The pkgsrc infrastructure consists of many small Makefile
fragments. Each such fragment needs a properly specified
interface. This chapter explains how such an interface looks
like.</p>

<a name="infr.vardef"></a>24.1. The meaning of variable definitions</h2></div></div></div>
<p>Whenever a variable is defined in the pkgsrc
infrastructure, the location and the way of definition provide
much information about the intended use of that variable.
Additionally, more documentation may be found in a header
comment or in this pkgsrc guide.</p>
<p>A special file is
<code class="filename">mk/defaults/mk.conf</code>, which lists all
variables that are intended to be user-defined. They are either
defined using the <code class="literal">?=</code> operator or they are
left undefined because defining them to anything would
effectively mean “<span class="quote">yes</span>”. All these variables may be
overridden by the pkgsrc user in the <code class="varname">MAKECONF</code>
file.</p>
<p>Outside this file, the following conventions apply:
Variables that are defined using the <code class="literal">?=</code>
operator may be overridden by a package.</p>
<p>Variables that are defined using the <code class="literal">=</code>
operator may be used read-only at run-time.</p>
<p>Variables whose name starts with an underscore must not be
accessed outside the pkgsrc infrastructure at all. They may
change without further notice.</p>
<div class="note" style="margin-left: 0.5in; margin-right: 0.5in;">
<h3 class="title">Note</h3>
<p>These conventions are currently not applied
consistently to the complete pkgsrc
infrastructure.</p>

<div class="titlepage"><div><div><h2 class="title" style="clear: both">
<a name="infr.vardef.problems"></a>24.2. Avoiding problems before they arise</h2></div></div></div>
<p>All variables that contain lists of things should default
to being empty. Two examples that do not follow this rule are
<code class="varname">USE_LANGUAGES</code> and
<code class="varname">DISTFILES</code>. These variables cannot simply be
modified using the <code class="literal">+=</code> operator in package
<code class="filename">Makefile</code>s (or other files included by
them), since there is no guarantee whether the variable is
already set or not, and what its value is. In the case of
<code class="varname">DISTFILES</code>, the packages “<span class="quote">know</span>”
the default value and just define it as in the following
example.</p>
<pre class="programlisting">
DISTFILES= ${DISTNAME}${EXTRACT_SUFX} additional-files.tar.gz
</pre>
<p>Because of the selection of this default value, the same
value appears in many package Makefiles. Similarly for
<code class="varname">USE_LANGUAGES</code>, but in this case the default
value (“<span class="quote"><code class="literal">c</code></span>”) is so short that it
doesn't stand out. Nevertheless it is mentioned in many
files.</p>

<div class="sect2" lang="en">
<div class="titlepage"><div><div><h3 class="title">
<a name="infr.var.load"></a>24.3.1. At load time</h3></div></div></div>
<p>Variable evaluation takes place either at load time or at
runtime, depending on the context in which they occur. The
contexts where variables are evaluated at load time are:</p>
<div class="itemizedlist"><ul type="disc">
<li><p>The right hand side of the <code class="literal">:=</code>
and <code class="literal">!=</code> operators,</p></li>
<li><p>Make directives like <code class="literal">.if</code> or
<code class="literal">.for</code>,</p></li>
<li><p>Dependency lines.</p></li>
</ul></div>
<p>A special exception are references to the iteration
variables of <code class="literal">.for</code> loops, which are expanded
inline, no matter in which context they appear.</p>
<p>As the values of variables may change during load time,
care must be taken not to evaluate them by accident. Typical
examples for variables that should not be evaluated at load time
are <code class="varname">DEPENDS</code> and
<code class="varname">CONFIGURE_ARGS</code>. To make the effect more
clear, here is an example:</p>
<pre class="programlisting">
CONFIGURE_ARGS= # none
CFLAGS= -O
CONFIGURE_ARGS+= CFLAGS=${CFLAGS:Q}
CONFIGURE_ARGS:= ${CONFIGURE_ARGS}
CFLAGS+= -Wall
</pre>
<p>This code shows how the use of the <code class="literal">:=</code>
operator can quickly lead to unexpected results. The first
paragraph is fairly common code. The second paragraph evaluates
the <code class="varname">CONFIGURE_ARGS</code> variable, which results in
<code class="literal">CFLAGS=-O</code>. In the third paragraph, the
<code class="literal">-Wall</code> is appended to the
<code class="varname">CFLAGS</code>, but this addition will not appear in
<code class="varname">CONFIGURE_ARGS</code>. In actual code, the three
paragraphs from above typically occur in completely unrelated
files.</p>

<a name="infr.varspec"></a>24.4. How can variables be specified?</h2></div></div></div>
<p>There are many ways in which the definition and use of a

<code class="literal">pkglint</code> developer's documentation for further
details.</p>

<a name="infr.design.intf"></a>24.5. Designing interfaces for Makefile fragments</h2></div></div></div>
<p>Most of the <code class="filename">.mk</code> files fall into one
of the following classes. Cases where a file falls into more
than one class should be avoided as it often leads to subtle
bugs.</p>
<div class="sect2" lang="en">
<div class="titlepage"><div><div><h3 class="title">
<a name="infr.design.intf.proc"></a>24.5.1. Procedures with parameters</h3></div></div></div>
<p>In a traditional imperative programming language some of
the <code class="filename">.mk</code> files could be described as
procedures. They take some input parameters and—after
inclusion—provide a result in output parameters. Since all
variables in <code class="filename">Makefile</code>s have global scope
care must be taken not to use parameter names that have already
another meaning. For example, <code class="varname">PKGNAME</code> is a
bad choice for a parameter name.</p>
<p>Procedures are completely evaluated at preprocessing time.
That is, when calling a procedure all input parameters must be
completely resolvable. For example,
<code class="varname">CONFIGURE_ARGS</code> should never be an input
parameter since it is very likely that further text will be
added after calling the procedure, which would effectively apply
the procedure to only a part of the variable. Also, references
to other variables wit will be modified after calling the
procedure.</p>
<p>A procedure can declare its output parameters either as
suitable for use in preprocessing directives or as only
available at runtime. The latter alternative is for variables
that contain references to other runtime variables.</p>
<p>Procedures shall be written such that it is possible to
call the procedure more than once. That is, the file must not
contain multiple-inclusion guards.</p>
<p>Examples for procedures are
<code class="filename">mk/bsd.options.mk</code> and
<code class="filename">mk/buildlink3/bsd.builtin.mk</code>. To express
that the parameters are evaluated at load time, they should be
assigned using the <code class="literal">:=</code> operator, which should
be used only for this purpose.</p>

<div class="titlepage"><div><div><h3 class="title">
<a name="infr.design.intf.action"></a>24.5.2. Actions taken on behalf of parameters</h3></div></div></div>
<p>Action files take some input parameters and may define
runtime variables. They shall not define loadtime variables.
There are action files that are included implicitly by the
pkgsrc infrastructure, while other must be included
explicitly.</p>
<p>An example for action files is
<code class="filename">mk/subst.mk</code>.</p>

<a name="infr.order"></a>24.6. The order in which files are loaded</h2></div></div></div>
<p>Package <code class="filename">Makefile</code>s usually consist of
a set of variable definitions, and include the file
<code class="filename">../../mk/bsd.pkg.mk</code> in the very last line.
Before that, they may also include various other
<code class="filename">*.mk</code> files if they need to query the
availability of certain features like the type of compiler or
the X11 implementation. Due to the heavy use of preprocessor
directives like <code class="literal">.if</code> and
<code class="literal">.for</code>, the order in which the files are loaded
matters.</p>
<p>This section describes at which point the various files
are loaded and gives reasons for that order.</p>
<div class="sect2" lang="en">
<div class="titlepage"><div><div><h3 class="title">
<a name="infr.order.prefs"></a>24.6.1. The order in <code class="filename">bsd.prefs.mk</code>
</h3></div></div></div>
<p>The very first action in <code class="filename">bsd.prefs.mk</code>
is to define some essential variables like
<code class="varname">OPSYS</code>, <code class="varname">OS_VERSION</code> and
<code class="varname">MACHINE_ARCH</code>.</p>
<p>Then, the user settings are loaded from the file specified
in <code class="varname">MAKECONF</code>, which is usually <a class="link" href="#mk.conf"><code class="filename">mk.conf</code></a>.
After that, those variables
that have not been overridden by the user are loaded from
<code class="filename">mk/defaults/mk.conf</code>.</p>
<p>After the user settings, the system settings and platform
settings are loaded, which may override the user
settings.</p>
<p>Then, the tool definitions are loaded. The tool wrappers
are not yet in effect. This only happens when building a
package, so the proper variables must be used instead of the
direct tool names.</p>
<p>As the last steps, some essential variables from the
wrapper and the package system flavor are loaded, as well as the
variables that have been cached in earlier phases of a package
build.</p>
</div>
<div class="sect2" lang="en">
<div class="titlepage"><div><div><h3 class="title">
<a name="infr.order.pkg"></a>24.6.2. The order in <code class="filename">bsd.pkg.mk</code>
</h3></div></div></div>
<p>First, <code class="filename">bsd.prefs.mk</code> is loaded.</p>
<p>Then, the various <code class="filename">*-vars.mk</code> files are
loaded, which fill default values for those variables that have
not been defined by the package. These variables may later
be used even in unrelated files.</p>
<p>Then, the file <code class="filename">bsd.pkg.error.mk</code>
provides the target <code class="literal">error-check</code> that is added
as a special dependency to all other targets that use
<code class="varname">DELAYED_ERROR_MSG</code> or
<code class="varname">DELAYED_WARNING_MSG</code>.</p>
<p>Then, the package-specific hacks from
<code class="filename">hacks.mk</code> are included.</p>
<p>Then, various other files follow. Most of them don't have
any dependencies on what they need to have included before or
after them, though some do.</p>
<p>The code to check <code class="varname">PKG_FAIL_REASON</code> and
<code class="varname">PKG_SKIP_REASON</code> is then executed, which
restricts the use of these variables to all the files that have
been included before. Appearances in later files will be
silently ignored.</p>
<p>Then, the files for the main targets are included, in the
order of later execution, though the actual order should not
matter.</p>
<p>At last, some more files are included that don't set any
interesting variables but rather just define make targets to be
executed.</p>

<p>The pkgsrc infrastructure consists of a large codebase,
and there are many corners where every little bit of a file is
well thought out, making pkgsrc likely to fail as soon as
anything is changed near those parts. To prevent most changes
from breaking anything, a suite of regression tests should go
along with every important part of the pkgsrc infrastructure.
This chapter describes how regression tests work in pkgsrc and
how you can add new tests.</p>

</div>
<p>The pkgsrc system has already been ported to many
operating systems, hardware architectures and compilers. This
chapter explains the necessary steps to make pkgsrc even more
portable.</p>
<div class="sect1" lang="en">
<div class="titlepage"><div><div><h2 class="title" style="clear: both">
<a name="porting.opsys"></a>26.1. Porting pkgsrc to a new operating system</h2></div></div></div>
<p>To port pkgsrc to a new operating system (called
<code class="literal">MyOS</code> in this example), you need to touch the
following files:</p>
<div class="variablelist"><dl>
<dt><span class="term"><code class="filename">pkgtools/bootstrap-mk-files/files/mods/<em class="replaceable"><code>MyOS</code></em>.sys.mk</code></span></dt>

compiler.</p></dd>
<dt><span class="term"><code class="filename">mk/bsd.prefs.mk</code></span></dt>
<dd><p>Insert code that defines the variables
<code class="varname">OPSYS</code>, <code class="varname">OS_VERSION</code>,
<code class="varname">LOWER_OS_VERSION</code>,
<code class="varname">LOWER_VENDOR</code>,
<code class="varname">MACHINE_ARCH</code>, <code class="varname">OBJECT_FMT</code>,
<code class="varname">APPEND_ELF</code>, and the other variables that
appear in this file.</p></dd>
<dt><span class="term"><code class="filename">mk/platform/<em class="replaceable"><code>MyOS</code></em>.mk</code></span></dt>
<dd><p>This file contains the platform-specific
definitions that are used by pkgsrc. Start by copying one of the
other files and edit it to your
needs.</p></dd>
<dt><span class="term"><code class="filename">mk/platform/<em class="replaceable"><code>MyOS</code></em>.pkg.dist</code></span></dt>
<dd><p>This file contains a list of directories,
together with their permission bits and ownership. These
directories will be created automatically with every package
that explicitly sets <code class="varname">USE_MTREE</code>. This feature will
be removed.</p></dd>
<dt><span class="term"><code class="filename">mk/platform/<em class="replaceable"><code>MyOS</code></em>.x11.dist</code></span></dt>
<dd><p>Just copy one of the pre-existing x11.dist files
to your
<code class="filename"><em class="replaceable"><code>MyOS</code></em>.x11.dist</code>.</p></dd>
<dt><span class="term"><code class="filename">mk/tools/bootstrap.mk</code></span></dt>
<dd><p>On some operating systems, the tools that are
provided with the base system are not good enough for pkgsrc.
For example, there are many versions of <a class="citerefentry" href="http://netbsd.gw.com/cgi-bin/man-cgi?sed+1+NetBSD-current"><span class="citerefentry"><span class="refentrytitle">sed</span>(1)</span></a> that have a
narrow limit on the line length they can process. Therefore
pkgsrc brings its own tools, which can be enabled
here.</p></dd>
<dt><span class="term"><code class="filename">mk/tools/tools.<em class="replaceable"><code>MyOS</code></em>.mk</code></span></dt>
<dd><p>This file defines the paths to all the tools
that are needed by one or the other package in pkgsrc, as well
as by pkgsrc itself. Find out where these tools are on your
platform and add them.</p></dd>
</dl></div>
<p>Now, you should be able to build some basic packages, like
<a href="ftp://ftp.NetBSD.org/pub/pkgsrc/current/pkgsrc/lang/perl5/README.html" target="_top"><code class="filename">lang/perl5</code></a>, <a href="ftp://ftp.NetBSD.org/pub/pkgsrc/current/pkgsrc/shells/bash/README.html" target="_top"><code class="filename">shells/bash</code></a>.</p>

</div>
<p>As in other big projects, the directory layout of pkgsrc
is quite complex for newbies. This chapter explains where you
find things on the FTP server. The base directory on
<code class="filename">ftp.NetBSD.org</code> is <a class="ulink" href="ftp://ftp.NetBSD.org/pub/pkgsrc/" target="_top"><code class="filename">/pub/pkgsrc/</code></a>.
On other servers it may be different, but inside this directory,
everything should look the same, no matter on which server you
are. This directory contains some subdirectories, which are
explained below.</p>
<div class="sect1" lang="en">
<div class="titlepage"><div><div><h2 class="title" style="clear: both">
<a name="ftp-bootstrap"></a>C.1. <code class="filename">bootstrap-pkgsrc</code>: Bootstrap kits</h2></div></div></div>
<p>This directory used to contain binary packages of the
package management tools for various platforms. For those
package collections that need them, they are now stored near the
binary packages, so you should look <a class="link" href="#ftp-packages" title="C.5. packages: Binary packages">in the <code class="filename">packages</code>
directory</a>.</p>
</div>
<div class="sect1" lang="en">
<div class="titlepage"><div><div><h2 class="title" style="clear: both">
<a name="ftp-distfiles"></a>C.2. <code class="filename">distfiles</code>: The distributed source files</h2></div></div></div>
<p>The directory <code class="filename">distfiles</code> contains lots
of archive files from all pkgsrc packages, which are mirrored
here. The subdirectories are called after their package names
and are used when the distributed files have names that don't
explicitly contain a version number or are otherwise too generic
(for example <code class="filename">release.tar.gz</code>).</p>
</div>
<div class="sect1" lang="en">
<div class="titlepage"><div><div><h2 class="title" style="clear: both">
<a name="ftp-iso"></a>C.3. <code class="filename">iso</code>: Currently empty</h2></div></div></div>
<p>This directory is currently not in use.</p>
</div>
<div class="sect1" lang="en">
<div class="titlepage"><div><div><h2 class="title" style="clear: both">
<a name="ftp-misc"></a>C.4. <code class="filename">misc</code>: Miscellaneous things</h2></div></div></div>
<p>This directory contains things that individual pkgsrc
developers find worth publishing.</p>
</div>
<div class="sect1" lang="en">
<div class="titlepage"><div><div><h2 class="title" style="clear: both">
<a name="ftp-packages"></a>C.5. <code class="filename">packages</code>: Binary packages</h2></div></div></div>
<p>This directory contains binary packages for the various
platforms that are supported by pkgsrc.
Each subdirectory is of the form <em class="replaceable"><code>OPSYS</code></em>/<em class="replaceable"><code>ARCH</code></em>/<em class="replaceable"><code>OSVERSION_TAG</code></em>. The meaning of these variables is:</p>
<div class="itemizedlist"><ul type="disc">
<li><p><code class="varname">OPSYS</code> is the name of the
operating system for which the packages have been built. The
name is taken from the output of the <span class="command"><strong>uname</strong></span>
command, so it may differ from the one you are used to
hear.</p></li>
<li><p><code class="varname">ARCH</code> is the hardware
architecture of the platform for which the packages have been
built. It also includes the <code class="varname">ABI</code> (Application
Binary Interface) for platforms that have several of
them.</p></li>
<li><p><code class="varname">OSVERSION</code> is the version of
the operating system. For version numbers that change often (for
example NetBSD-current), the often-changing part should be
replaced with an <code class="literal">x</code>, for example
<code class="literal">4.99.x</code>.</p></li>
<li><p><code class="varname">TAG</code> is either
<code class="literal">200<em class="replaceable"><code>x</code></em>Q<em class="replaceable"><code>y</code></em></code>
for a stable branch, or <code class="literal">head</code> for packages
built from the HEAD branch. The latter should only be used when
the packages are updated on a regular basis. Otherwise the date
from checking out pkgsrc should be appended, for example
<code class="literal">head_20071015</code>.</p></li>
</ul></div>
<p>The rationale for exactly this scheme is that the pkgsrc users looking for binary packages
can quickly click through the directories on the
server and find the best binary packages for their machines. Since they
usually know the operating system and the hardware architecture, OPSYS
and ARCH are placed first. After these choices, they can select the
best combination of OSVERSION and TAG together, since it is usually the
case that packages stay compatible between different version of the
operating system.</p>
<p>In each of these directories, there is a
whole binary packages collection for a specific platform. It has a directory called
<code class="filename">All</code> which contains all binary packages.
Besides that, there are various category directories that
contain symbolic links to the real binary packages.</p>
</div>
<div class="sect1" lang="en">
<div class="titlepage"><div><div><h2 class="title" style="clear: both">
<a name="ftp-reports"></a>C.6. <code class="filename">reports</code>: Bulk build reports</h2></div></div></div>
<p>Here are the reports from bulk builds, for those who want
to fix packages that didn't build on some of the platforms. The
structure of subdirectories should look like the one in <a class="xref" href="#ftp-packages" title="C.5. packages: Binary packages">Section C.5, “<code class="filename">packages</code>: Binary packages”</a>.</p>
</div>
<div class="sect1" lang="en">
<div class="titlepage"><div><div><h2 class="title" style="clear: both">
<a name="ftp-source"></a>C.7. <code class="filename">current</code>,
<code class="filename">pkgsrc-200<em class="replaceable"><code>x</code></em>Q<em class="replaceable"><code>y</code></em></code>:
source packages</h2></div></div></div>
<p>These directories contain the “<span class="quote">real</span>” pkgsrc,
that is the files that define how to create binary packages from
source archives.</p>
<p>The directory <code class="filename">pkgsrc</code> contains a
snapshot of the CVS repository, which is updated regularly. The
file <code class="filename">pkgsrc.tar.gz</code> contains the same as the
directory, ready to be downloaded as a whole.</p>
<p>In the directories for the quarterly branches, there is an
additional file called
<code class="filename">pkgsrc-200<em class="replaceable"><code>x</code></em>Q<em class="replaceable"><code>y</code></em>.tar.gz</code>,
which contains the state of pkgsrc when it was branched.</p>
