<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 class="itemizedlist" style="list-style-type: disc; ">

	  Desktop Environment</p></li>
</ul></div>
<p>&#8230; 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">
<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 class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem"><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 class="listitem"><p>All packages are installed in a consistent directory tree,
  including binaries, libraries, man pages and other
  documentation.</p></li>
<li class="listitem"><p>Tracking of package dependencies automatically, including when
  performing updates, to ensure required packages are installed. The
  configuration files of various packages are handled automatically during
  updates, so local changes are preserved.</p></li>
<li class="listitem"><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 a new platform. This portability also
  ensures that pkgsrc is <span class="emphasis"><em>consistent across all
  platforms</em></span>.</p></li>
<li class="listitem"><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 class="listitem"><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 class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem"><p><span class="quote">&#8220;<span class="quote">It should only work if it's right.</span>&#8221;</span>
&mdash; 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="https://cdn.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 class="listitem"><p><span class="quote">&#8220;<span class="quote">If it works, it should work everywhere</span>&#8221;</span>
&mdash; 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>
</div>
<div class="sect2">
<div class="titlepage"><div><div><h3 class="title">
<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>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">
<div class="titlepage"><div><div><h2 class="title" style="clear: both">
<a name="getting-first"></a>3.1. 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">2020Q4</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 or via CVS.
	Both ways are described here.</p>
<p>Note that tar archive contains CVS working copy.
	Thus you can switch to using CVS at any later time.</p>
<div class="sect2">
<div class="titlepage"><div><div><h3 class="title">
<a name="getting-via-tar"></a>3.1.1. As tar archive</h3></div></div></div>
<p>The primary download location for all pkgsrc files is
	<a class="ulink" href="https://cdn.NetBSD.org/pub/pkgsrc/" target="_top">https://cdn.NetBSD.org/pub/pkgsrc/</a> or
	<a class="ulink" href="ftp://ftp.NetBSD.org/pub/pkgsrc/" target="_top">ftp://ftp.NetBSD.org/pub/pkgsrc/</a>
	(it points to the same location).
	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 archive for the current branch is in the directory
	<code class="filename">current</code> and is called <a class="ulink" href="https://cdn.NetBSD.org/pub/pkgsrc/current/pkgsrc.tar.gz" target="_top"><code class="filename">pkgsrc.tar.gz</code></a>.
	It is autogenerated weekly.</p>
<p>To save download time we provide bzip2- and
	xz-compressed archives which are published at
	<a class="ulink" href="https://cdn.NetBSD.org/pub/pkgsrc/current/pkgsrc.tar.bz2" target="_top"><code class="filename">pkgsrc.tar.bz2</code></a>
	and
	<a class="ulink" href="https://cdn.NetBSD.org/pub/pkgsrc/current/pkgsrc.tar.xz" target="_top"><code class="filename">pkgsrc.tar.xz</code></a>
	respectively.
	</p>
<p>You can fetch the same files using FTP.</p>
<p>The tar file for the stable branch 2020Q4 is in the
	directory <code class="filename">pkgsrc-2020Q4</code> and is also called <a class="ulink" href="https://cdn.NetBSD.org/pub/pkgsrc/pkgsrc-2020Q4/pkgsrc.tar.gz" target="_top"><code class="filename">pkgsrc.tar.gz</code></a>.</p>
<p>To download the latest pkgsrc stable tarball, run:</p>
<pre class="screen">
<code class="prompt">$</code> <strong class="userinput"><code>ftp ftp://ftp.NetBSD.org/pub/pkgsrc/pkgsrc-2020Q4/pkgsrc.tar.gz</code></strong></pre>
<p>If you prefer, you can also fetch it using "wget", "curl",
	or your web browser.</p>
<p>Then, extract it with:</p>
<pre class="screen"><code class="prompt">$</code> <strong class="userinput"><code>tar -xzf pkgsrc.tar.gz -C /usr</code></strong></pre>
<p>This will create the directory <code class="filename">pkgsrc/</code>
	in <code class="filename">/usr/</code> and all the package source will be 
	stored under <code class="filename">/usr/pkgsrc/</code>.</p>
<p>To download pkgsrc-current, run:</p>
<pre class="screen"><code class="prompt">$</code> <strong class="userinput"><code>ftp ftp://ftp.NetBSD.org/pub/pkgsrc/current/pkgsrc.tar.gz</code></strong></pre>

<div class="sect2">
<div class="titlepage"><div><div><h3 class="title">
<a name="getting-via-cvs"></a>3.1.2. Via anonymous CVS</h3></div></div></div>
<p>To fetch a specific pkgsrc stable branch, run:</p>
<pre class="screen"><code class="prompt">$</code> <strong class="userinput"><code>cd /usr &amp;&amp; cvs -q -z2 -d anoncvs@anoncvs.NetBSD.org:/cvsroot checkout -r pkgsrc-2020Q4 -P pkgsrc</code></strong>
</pre>
<p>This will create the directory <code class="filename">pkgsrc/</code> 
	in your <code class="filename">/usr/</code> directory and all the package source 
	will be stored under <code class="filename">/usr/pkgsrc/</code>.</p>
<p>To fetch the pkgsrc current branch, run:</p>
<pre class="screen"><code class="prompt">$</code> <strong class="userinput"><code>cd /usr &amp;&amp; cvs -q -z2 -d anoncvs@anoncvs.NetBSD.org:/cvsroot checkout -P pkgsrc</code></strong>
</pre>
<p>Refer to the <a class="ulink" href="https://www.NetBSD.org/mirrors/#anoncvs" target="_top">list of available mirrors</a> to choose a faster CVS mirror, if needed.</p>
<p>If you get error messages from <code class="literal">rsh</code>, you need to set CVS_RSH variable. E.g.:</p>
<pre class="screen"><code class="prompt">$</code> <strong class="userinput"><code>cd /usr &amp;&amp; env CVS_RSH=ssh cvs -q -z2 -d anoncvs@anoncvs.NetBSD.org:/cvsroot checkout -P pkgsrc</code></strong>
</pre>
<p>Refer to documentation on your command shell how to set CVS_RSH=ssh permanently.
	For Bourne shells, you can set it in your <code class="filename">.profile</code>
	or better globally in <code class="filename">/etc/profile</code>:</p>
<pre class="programlisting">
# set CVS remote shell command
CVS_RSH=ssh
export CVS_RSH
</pre>
<p>By default, CVS doesn't do things like most people would expect it to do.
	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>

<a name="uptodate"></a>3.2. 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="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 store distfiles
        and packages in directories outside the pkgsrc tree by setting the
	<code class="varname">DISTDIR</code> and <code class="varname">PACKAGES</code>
	variables. See <a class="xref" href="#configuring" title="Chapter 6. Configuring pkgsrc">Chapter 6, <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>

<pre class="screen"><code class="prompt">$</code> <strong class="userinput"><code>cd /usr/pkgsrc &amp;&amp; cvs update -dP</code></strong>
</pre>
<p>If you get error messages from <code class="literal">rsh</code>, you need to set CVS_RSH variable as described above. E.g.:</p>

<p>When updating pkgsrc, the CVS program keeps track of the

	switch from the stable branch to the current one, you can do it
	by adding the option <span class="quote">&#8220;<span class="quote">-A</span>&#8221;</span> after the
	<span class="quote">&#8220;<span class="quote">update</span>&#8221;</span> keyword. To switch from the current branch

<a name="uptodate-cvs-changes"></a>3.2.2.2. What happens to my changes when updating?</h4></div></div></div>
<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

<p>pkgsrc can be bootstrapped for use in two different modes:
    privileged and unprivileged one. In unprivileged mode in contrast
    to privileged one all programs are installed under one particular user
    and cannot utilise privileged operations (packages don't create
    special users and all special file permissions like setuid are ignored).
    </p>
<p>Installing the bootstrap kit from source should be as simple as:</p>
<pre class="screen">
<code class="prompt">#</code> <strong class="userinput"><code>env CVS_RSH=ssh cvs -d anoncvs@anoncvs.NetBSD.org:/cvsroot checkout -P pkgsrc</code></strong>
<code class="prompt">#</code> <strong class="userinput"><code>cd pkgsrc/bootstrap</code></strong>
<code class="prompt">#</code> <strong class="userinput"><code>./bootstrap</code></strong>
    </pre>
<p>To bootstrap in unprivileged mode pass <span class="quote">&#8220;<span class="quote">--unprivileged</span>&#8221;</span> flag to <span class="command"><strong>bootstrap</strong></span></p>
<p>By default, in privileged mode pkgsrc uses
    <code class="filename">/usr/pkg</code> for <span class="emphasis"><em>prefix</em></span>
    where programs will be installed in,
    and <code class="filename">/usr/pkg/pkgdb</code> for the package database
    directory where pkgsrc will do its internal bookkeeping,
    <code class="filename">/var</code> is used as <span class="emphasis"><em>varbase</em></span>,
    where packages install their persistent data.
    In unprivileged mode pkgsrc uses
    <code class="filename">~/pkg</code> for <span class="emphasis"><em>prefix</em></span>,
    <code class="filename">~/pkg/pkgdb</code> for the package database,
    and <code class="filename">~/pkg/var</code> for <span class="emphasis"><em>varbase</em></span>.
    </p>
<p>You can change default layout using command-line arguments.
    Run <span class="quote">&#8220;<span class="quote">./bootstrap --help</span>&#8221;</span> to get details.
    </p>
<div class="note" style="margin-left: 0.5in; margin-right: 0.5in;">
<h3 class="title">Note</h3>
<p>The bootstrap installs a <span class="command"><strong>bmake</strong></span> tool.
      Use this <span class="command"><strong>bmake</strong></span> when building via pkgsrc.
      For examples in this guide, use <span class="command"><strong>bmake</strong></span>
      instead of <span class="quote">&#8220;<span class="quote">make</span>&#8221;</span>.</p>
</div>
<div class="note" style="margin-left: 0.5in; margin-right: 0.5in;">
<h3 class="title">Note</h3>
<p>It is possible to bootstrap multiple instances of pkgsrc
      using non-intersecting directories. Use <span class="command"><strong>bmake</strong></span>
      corresponding to the installation you're working with to build
      and install packages.

<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">&#8220;<span class="quote">pkg</span>&#8221;</span>
in pkgsrc. The second way is to install the <span class="quote">&#8220;<span class="quote">src</span>&#8221;</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">
<div class="titlepage"><div><div><h2 class="title" style="clear: both">
<a name="using-pkg"></a>5.1. Using binary packages</h2></div></div></div>
<p>On the <a class="ulink" href="http://cdn.NetBSD.org/" target="_top">cdn.NetBSD.org</a>
  site and 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 class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem"><p><code class="filename">/usr/pkg</code> for <code class="varname">LOCALBASE</code>, where most of the files are installed,</p></li>
<li class="listitem"><p><code class="filename">/usr/pkg/etc</code> for configuration files,</p></li>
<li class="listitem"><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="4.2. Bootstrapping pkgsrc">Section 4.2, &#8220;Bootstrapping pkgsrc&#8221;</a>.</p>
<div class="sect2">
<div class="titlepage"><div><div><h3 class="title">
<a name="finding-binary-packages"></a>5.1.1. 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="http://cdn.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">&#8220;<span class="quote">version</span>&#8221;</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 the database of installed packages).</p>
</div>
<div class="sect2">
<div class="titlepage"><div><div><h3 class="title">
<a name="installing-binary-packages"></a>5.1.2. 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).</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="http://cdn.NetBSD.org/pub/pkgsrc/packages"</code></strong>
<code class="prompt">#</code> <strong class="userinput"><code>PKG_PATH="$PKG_PATH/<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 libreoffice</code></strong>
<code class="prompt">#</code> <strong class="userinput"><code>pkg_add ap24-php71-*</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>Adding packages might install vulnerable packages.
    Thus you should run <span class="command"><strong>pkg_admin audit</strong></span>
    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">
<div class="titlepage"><div><div><h3 class="title">
<a name="using.pkg_delete"></a>5.1.3. 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 pkgsrc Security Team 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="http://ftp.NetBSD.org/pub/NetBSD/packages/vulns/pkg-vulnerabilities" target="_top">http://ftp.NetBSD.org/pub/NetBSD/packages/vulns/pkg-vulnerabilities</a>.
    </p>
<p>
      Through <span class="command"><strong>pkg_admin fetch-pkg-vulnerabilities</strong></span>,
      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 auditing.  The first
      step, <span class="command"><strong>pkg_admin fetch-pkg-vulnerabilities</strong></span>,
      is for downloading
      the list of vulnerabilities from the NetBSD FTP site.  The second
      step, <span class="command"><strong>pkg_admin audit</strong></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
    https://www.samba.org/samba/whatsnew/macroexploit.html</pre>
<p>
      You may wish to have the
      
      <a class="ulink" href="http://ftp.NetBSD.org/pub/pkgsrc/distfiles/vulnerabilities" target="_top">vulnerabilities</a>
      file downloaded daily so that
      it remains current.  This may be done by adding an appropriate entry
      to the root users <a class="citerefentry" href="https://man.NetBSD.org/NetBSD-9.1/i386/crontab.5"><span class="citerefentry"><span class="refentrytitle">crontab</span>(5)</span></a> entry.  For example the entry
      </p>
<pre class="screen">
# Download vulnerabilities file
0 3 * * * /usr/pkg/sbin/pkg_admin fetch-pkg-vulnerabilities &gt;/dev/null 2&gt;&amp;1
# Audit the installed packages and email results to root
9 3 * * * /usr/pkg/sbin/pkg_admin audit |mail -s "Installed package audit result" \
	    root &gt;/dev/null 2&gt;&amp;1
      </pre>
<p>
      will update the vulnerability list every day at 3AM, followed by an audit
      at 3:09AM. The result of the audit are then emailed to root.

      On NetBSD this may be accomplished instead by adding the following
      line to <code class="filename">/etc/daily.conf</code>:
      </p>
<pre class="screen">
fetch_pkg_vulnerabilities=YES
      </pre>
<p>
      to fetch the vulnerability list from the daily security script. The system
      is set to audit the packages by default but can be set explicitly, if
      desired (not required), by adding the following line to
<code class="filename">/etc/security.conf</code>:
      </p>
<pre class="screen">
check_pkg_vulnerabilities=YES
      </pre>

<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>

<p>The default <span class="emphasis"><em>prefix</em></span> for installed packages

<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, &#8220;The pkgsrc developer's guide&#8221;</a> for

<a name="requirements"></a>5.2.1. 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">&#8220;<span class="quote">comp</span>&#8221;</span> and the <span class="quote">&#8220;<span class="quote">text</span>&#8221;</span> distribution
    sets. If you want to build X11-related packages, the
    <span class="quote">&#8220;<span class="quote">xbase</span>&#8221;</span> and <span class="quote">&#8220;<span class="quote">xcomp</span>&#8221;</span> distribution
    sets are required, too.</p>
</div>
<div class="sect2">
<div class="titlepage"><div><div><h3 class="title">
<a name="fetching-distfiles"></a>5.2.2. 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="https://cdn.NetBSD.org/pub/pkgsrc/current/pkgsrc/meta-pkgs/kde4/README.html" target="_top"><code class="filename">meta-pkgs/kde4</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.

<div class="titlepage"><div><div><h3 class="title">
<a name="how-to-build-and-install"></a>5.2.3. 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">&#8220;<span class="quote">make</span>&#8221;</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">&#8220;<span class="quote">look under the
    covers</span>&#8221;</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>

    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="https://man.NetBSD.org/NetBSD-9.1/i386/pkg_add.1"><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="https://man.NetBSD.org/NetBSD-9.1/i386/make.1"><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>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.</p>

<p>Packages have to support installation into a

<p>With basic DESTDIR support, <strong class="userinput"><code>make

<p>Considering the <code class="filename">foo/bar</code> package,
    DESTDIR full support can be tested using the following commands

</p>
<pre class="programlisting">
<code class="prompt">$</code> id

    should be needed

</p>
<pre class="programlisting">
<code class="prompt">$</code> make stage-install

<p>

    Create a package without root privileges

</p>
<pre class="programlisting">

<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">&#8220;<span class="quote">-</span>&#8221;</span>
    are disabled. A few examples:</p>
<pre class="screen">
<code class="prompt">$</code> <span class="command"><strong>grep "PKG.*OPTION" <a class="link" href="#mk.conf"><code class="filename">mk.conf</code></a></strong></span>
PKG_DEFAULT_OPTIONS=    -arts -dvdread -esound
PKG_OPTIONS.kdebase=    debug -sasl
PKG_OPTIONS.apache=     suexec </pre>
<p>It is important to note that options that were specifically
    suggested by the package maintainer must be explicitly removed if
    you do not wish to include the option.  If you are unsure you can view
    the current state with <span class="command"><strong>make show-options</strong></span>.</p>
<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 class="orderedlist" type="1">
<li class="listitem"><p>the default options as suggested by the package
      maintainer</p></li>
<li class="listitem"><p>the options implied by the settings of legacy
      variables (see below)</p></li>
<li class="listitem"><p><code class="varname">PKG_DEFAULT_OPTIONS</code></p></li>
<li class="listitem"><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
    eventually.</p>

<p>For a number of reasons, you may want to build binary packages
for a large selected set of packages in pkgsrc, or even for all pkgsrc packages.
For instance, when you have multiple machines that should run the same software,
it is wasted time if they all build their packages themselves from source.
Or you may want to build a list of packages you want and check them before
deploying onto production systems.
There is a way of getting a set of binary packages:
the bulk build system, or pbulk ("p" stands for "parallel").
This chapter describes how to set it up.</p>
<div class="sect1">
<div class="titlepage"><div><div><h2 class="title" style="clear: both">
<a name="bulk.pre"></a>8.1. Preparations</h2></div></div></div>
<p>First of all, you have to decide whether you build all packages
or a limited set of them. Full bulk builds usually consume a lot more resources,
both space and time, than builds for some practical sets of packages.
A number of particularly heavy packages exist that are not actually
interesting to a wide audience. (The approximate resource consumption for a
full bulk build is given in section <a class="xref" href="#bulk.req" title="8.3. Requirements of a full bulk build">Section 8.3, &#8220;Requirements of a full bulk build&#8221;</a>.)
For limited bulk builds you need to make a list of packages you want to build.
Note that all their dependencies will be built, so you don't need to track them manually.
</p>
<p>During bulk builds various packages are installed and deinstalled
in <code class="filename">/usr/pkg</code> (or whatever <code class="filename">LOCALBASE</code> is),
so make sure that you don't need any package during the builds.
Essentially, you should provide a fresh system, either a chroot environment
or something even more restrictive, depending on what the operating system provides,
or dedicate the whole physical machine.
As a useful side effect this makes sure that bulk builds cannot
break anything in your system. 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>.

<li class="listitem"><p>First, build the pbulk infrastructure in a fresh pkgsrc location.</p></li>

<p>To simplify configuration, we provide the helper script <code class="filename">mk/pbulk/pbulk.sh</code>.</p>
<p>In order to use it, prepare a clear system (real one, chroot environment, jail, zone, virtual machine).
Configure network access to fetch distribution files.
Create a user with name "pbulk".</p>
<p>Fetch and extract pkgsrc. Use a command like one of these:</p>
<pre class="screen">
<code class="prompt">#</code> <strong class="userinput"><code>(cd /usr &amp;&amp; ftp -o - https://cdn.NetBSD.org/pub/pkgsrc/current/pkgsrc.tar.gz | tar -zxf-)</code></strong>

</pre>
<p>Or any other way that fits (e.g., curl, wget).</p>
<p>Deploy and configure pbulk tools, e.g.:</p>
<pre class="screen">
<code class="prompt">#</code> <strong class="userinput"><code>sh pbulk.sh -n # use native make, no bootstrap kit needed (for use on NetBSD)</code></strong>

</pre>
<div class="note" style="margin-left: 0.5in; margin-right: 0.5in;">
<h3 class="title">Note</h3>
<p><code class="filename">mk.conf.frag</code> is a fragment of
<code class="filename">mk.conf</code> that contains settings you want to

                                # when building all packages)
</pre>
</div>
<p>If configured for limited list, replace the list in <code class="filename">/usr/pbulk/etc/pbulk.list</code>
with your list of packages, one per line without empty lines or comments. E.g.:</p>
<pre class="programlisting">

</pre>
<p>At this point you can also review configuration in <code class="filename">/usr/pbulk/etc</code>
and make final amendments, if wanted.</p>
<p>Start it:</p>
<pre class="screen">
<code class="prompt">#</code> <strong class="userinput"><code>/usr/pbulk/bin/bulkbuild</code></strong>

<p>After it finishes, you'll have <code class="filename">/mnt</code> filled with distribution files, binary packages, and reports,

<a name="bulk.var"></a>8.4. Bulk build variants</h2></div></div></div>
<p>To ensure that pkgsrc packages work in different configurations, it
makes sense to run non-default bulk builds from time to time. This
section lists some ideas for bulk builds that intentionally let packages
fail if they don't follow the pkgsrc style.</p>
<div class="sect2">
<div class="titlepage"><div><div><h3 class="title">
<a name="bulk.var.confopt"></a>8.4.1. Detect unknown configure options</h3></div></div></div>
<p>Add the following line to <a class="link" href="#mk.conf"><code class="filename">mk.conf</code></a>.</p>
<pre class="programlisting">
GNU_CONFIGURE_STRICT=   yes
</pre>
<p>When a package fails this additional check, the most common cause
is that the configure option was valid for an older version of the
package but does not apply anymore. In that case, just remove it.</p>
</div>
<div class="sect2">
<div class="titlepage"><div><div><h3 class="title">
<a name="bulk.var.comperr"></a>8.4.2. Detect classes of bugs by forcing compiler warnings</h3></div></div></div>
<p>The job of a compiler is not restricted to producing executable
code, most compilers also detect typical programming mistakes. The pkgsrc
compiler wrappers make it easy to force compiler options when the package
is built. This can be used to find typical bugs across all packages that
are in pkgsrc. By reporting these bugs upstream, the packages will be
more reliable with the next updates.</p>
<p>Add some of the following lines to <a class="link" href="#mk.conf"><code class="filename">mk.conf</code></a>:</p>
<pre class="programlisting">
CFLAGS+=        -Werror=char-subscripts
CFLAGS+=        -Werror=implicit-function-declaration
</pre>
<p>When a package fails to build using these stricter compiler
options, document the circumstances in which the compiler produced the
error message. This includes:</p>
<div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem"><p>The platform
(<code class="varname">MACHINE_PLATFORM</code>)</p></li>
<li class="listitem"><p>The source file</p></li>
<li class="listitem"><p>An excerpt of the code. GCC and Clang already do this as
part of the diagnostic.</p></li>
<li class="listitem"><p>The exact error message from the compiler.</p></li>
</ul></div>
<p>If a package produces these error messages, but the package is
fine, record this in your local <a class="link" href="#mk.conf"><code class="filename">mk.conf</code></a>, like this, to skip this check
in the next builds:</p>
<pre class="programlisting">
.if ${PKGPATH} == category/package
# Version ${VERSION} failed on ${MACHINE_PLATFORM}:
# error message
# code
# Reason why the code does not need to be fixed.
BUILDLINK_TRANSFORM+=   rm:-Werror=char-subscripts
.endif
</pre>
<p>If the error messages from the compiler are valid and the code
needs to be fixed, prepare a local patch (see
<code class="varname">LOCALPATCHES</code>) and report the bug to the upstream
authors of the package, providing them with the information you collected
above.</p>
<p>Patches that are not essential for the package to work should only
be reported upstream but not committed to pkgsrc, to make future updates
easier.</p>

<div class="sect2">
<div class="titlepage"><div><div><h3 class="title">
<a name="bulk.var.builderr"></a>8.4.3. Force compiler options only in the build phase</h3></div></div></div>
<p>When adding custom compiler flags via <code class="varname">CFLAGS</code>,
these apply to all phases of the package build process. Especially in the
configure phase, adding <code class="literal">-Werror</code> leads to wrong
decisions. The GNU configure scripts feed many small test programs to the
C compiler to see whether certain headers are available, functions are
defined in a library and programs can be run. In many cases these
programs would not survive a strict compiler run with <code class="literal">-Wall
-Wextra -Werror</code>.</p>
<p>The pkgsrc infrastructure is flexible enough to support compiler
options being added between the <code class="literal">configure</code> and
<code class="literal">build</code> phases. It's a little more complicated than the
other examples in this section but still easy enough.</p>
<p>The basic idea is to use the pkgsrc compiler wrapper to inject the
desired compiler options. The compiler wrapper's original task is to hide
unwanted directories of include files and to normalize compiler options.
It does this by wrapping the compiler command and rewriting the command
line. To see this in action, run <span class="command"><strong>bmake patch</strong></span> in a
package directory and examine the
<code class="filename">work/.cwrappers/config</code> directory. It contains
individual configurations for the C compiler and the related tools. The
plan is to find a hook between the configure and build phases, and to
modify these configuration files at that point.</p>
<p>To find this hook, have a look at
<code class="filename">mk/build/build.mk</code>, which contains among others the
<code class="literal">pre-build-checks-hook</code>. The word
<code class="literal">checks</code> doesn't quite fit, but the
<code class="literal">pre-build-hook</code> sounds good enough.</p>
<p>The code to be included in <a class="link" href="#mk.conf"><code class="filename">mk.conf</code></a> is:</p>
<pre class="programlisting">
# Just a few example options.
BUILD_ONLY_CFLAGS=      -Wall -Werror -O2 -DTEMPDIR='"/tmp"'

.if ${BUILD_ONLY_CFLAGS:U:M*}
pre-build-checks-hook: add-build-only-cflags

add-build-only-cflags: .PHONY
        ${RUN} cd ${CWRAPPERS_CONFIG_DIR};      \
        ${TEST} ! -f ${.TARGET} || exit 0;      \
        for flag in ${BUILD_ONLY_CFLAGS}; do    \
                ${ECHO} "append=$$flag" &gt;&gt; cc;  \
        done;                                   \
        &gt; ${.TARGET}
.endif
</pre>
<p>(When editing the <a class="link" href="#mk.conf"><code class="filename">mk.conf</code></a>, make sure that the commands of the
<code class="literal">add-build-only-cflags</code> target are indented with a tab,
not with spaces.)</p>
<p>The condition in the <code class="literal">.if</code> statement contains the
<code class="literal">:U</code> modifier to prevent parse errors if the variable
should be undefined, possibly because it is only defined for a subset of
the packages. The <code class="literal">:M*</code> modifier ensures that there is
at least one compiler option, to prevent a syntax error in the shell
parser.</p>
<p>The code around the <code class="literal">${.TARGET}</code> variable ensures
that the additional compiler options are only appended once, even if
<span class="command"><strong>bmake build</strong></span> is run multiple times. To do this, it
creates a marker file.</p>
<p>To verify that this setup works, run <span class="command"><strong>bmake
configure</strong></span> in a package directory. Up to now, everything works
as usual. Examine the directory
<code class="filename">work/.cwrappers/config</code> to see that the compiler
options from <code class="varname">BUILD_ONLY_CFLAGS</code> are not yet added to
the file <code class="filename">cc</code>. Examine the tail of the
<code class="filename">work/.work.log</code> file to see that the normal compiler
options are used.</p>
<p>Now run <span class="command"><strong>bmake build</strong></span>. This will append the
options to the file <code class="filename">cc</code> and will create the marker
file in the same directory. After that, the build starts as usual, but
with the added compiler options. Examine the tail of the file
<code class="filename">work/.work.log</code> to see that the lines starting with
<code class="literal">[*]</code> don't contain the compiler options, but the
corresponding lines starting with <code class="literal">&lt;.&gt;</code> do end
with these options.</p>
<p>Building packages using this setup variant and fixing the resulting
bugs is the same as in <a class="xref" href="#bulk.var.comperr" title="8.4.2. Detect classes of bugs by forcing compiler warnings">Section 8.4.2, &#8220;Detect classes of bugs by forcing compiler warnings&#8221;</a>.</p>

them can be redefined with a simple definition like above.</p>
<p>If a package suggests to add <code class="varname">USE_TOOLS+=perl</code> to
the package Makefile, research whether the package actually needs Perl.
If it does, add <code class="varname">USE_TOOLS+=perl</code> to the package
Makefile, and if it doesn't, add

<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>mkdir /u2/images</code></strong>
<code class="prompt">#</code> <strong class="userinput"><code>pkg_add /usr/pkgsrc/packages/All/cdpack</code></strong>
<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" &gt; /tmp/common/README</code></strong>
<code class="prompt">#</code> <strong class="userinput"><code>echo "Another file" &gt; /tmp/common/COPYING</code></strong>
<code class="prompt">#</code> <strong class="userinput"><code>mkdir /tmp/common/bin</code></strong>
<code class="prompt">#</code> <strong class="userinput"><code>echo "#!/bin/sh" &gt; /tmp/common/bin/myscript</code></strong>
<code class="prompt">#</code> <strong class="userinput"><code>echo "echo Hello world" &gt;&gt; /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>,
      <code class="filename">COPYING</code>, and <code class="filename">bin/myscript</code>
      in their root directories.</p>

<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=              /usr/pkg/pkgdb
</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/pkgdb
</pre>
<p>What these four directories are for, and what they look like is
explained below.</p>

<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 platform default program by changing the
<code class="varname">FETCH_USING</code> variable.  You can specify the program by
using of ftp, fetch, wget or curl.  Alternatively, fetching can be disabled
by using the value manual.  A value of custom disables the system defaults
and dependency tracking for the fetch program.  In that case you have to
provide <code class="varname">FETCH_CMD</code>, <code class="varname">FETCH_BEFORE_ARGS</code>,
<code class="varname">FETCH_RESUME_ARGS</code>, <code class="varname">FETCH_OUTPUT_ARGS</code>,
<code class="varname">FETCH_AFTER_ARGS</code>.</p>
<p>For example, if you want to use

<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">&#8220;<span class="quote">orpheus.amdahl.com</span>&#8221;</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="fetch-https"></a>10.7. How to fetch files from HTTPS sites</h2></div></div></div>
<p>Some fetch tools are not prepared to support HTTPS by default
(for example, the one in NetBSD 6.0), or the one installed by the
pkgsrc bootstrap (to avoid an openssl dependency that low in the
dependency graph).</p>
<p>Usually you won't notice, because distribution files are
mirrored weekly to <span class="quote">&#8220;<span class="quote">ftp.NetBSD.org</span>&#8221;</span>, but that might not
be often enough if you are following pkgsrc-current. In that case, set
<code class="varname">FETCH_USING</code> in your <a class="link" href="#mk.conf"><code class="filename">mk.conf</code></a> file to
<span class="quote">&#8220;<span class="quote">curl</span>&#8221;</span> or <span class="quote">&#8220;<span class="quote">wget</span>&#8221;</span>, which are both compiled
with HTTPS support by default. Of course, these tools need to be
installed before you can use them this way.</p>

<a name="passive-ftp"></a>10.8. 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 class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem"><p><code class="filename">${LOCALBASE}/bin/ftp</code></p></li>
<li class="listitem"><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
<code class="filename">/usr/bin/ftp</code> from falling back to active
transfers.</p>

<a name="fetching-all-distfiles"></a>10.9. 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
fetch</strong></span>.  There is an archive of distfiles on <a class="ulink" href="ftp://ftp.NetBSD.org/pub/pkgsrc/distfiles/" target="_top">ftp.NetBSD.org</a>,
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="https://man.NetBSD.org/NetBSD-9.1/i386/ftp.1"><span class="citerefentry"><span class="refentrytitle">ftp</span>(1)</span></a> (like tnftp) at work, don't
forget to set <code class="varname">FETCH_CMD</code> to something that fetches a
URL:</p>
<p>At home:</p>
<pre class="screen"><code class="prompt">%</code> <strong class="userinput"><code>cd /usr/pkgsrc</code></strong>
<code class="prompt">%</code> <strong class="userinput"><code>make fetch-list FETCH_CMD=wget DISTDIR=/tmp/distfiles &gt;/tmp/fetch.sh</code></strong>

<p>At work:</p>
<pre class="screen"><code class="prompt">%</code> <strong class="userinput"><code>sh /tmp/fetch.sh</code></strong></pre>
<p>then tar up <code class="filename">/tmp/distfiles</code> and take it
home.</p>
<p>If you have a machine running NetBSD, and you want to get
<span class="emphasis"><em>all</em></span> distfiles (even ones that aren't for your
machine architecture), you can do so by using the above-mentioned
<span class="command"><strong>make fetch-list</strong></span> approach, or fetch the distfiles
directly by running:</p>
<pre class="screen"><code class="prompt">%</code> <strong class="userinput"><code>make mirror-distfiles</code></strong></pre>
<p>If you even decide to ignore

<a name="faq.conf"></a>10.13. How do I change the location of configuration files?</h2></div></div></div>
<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">${PREFIX}/etc</code> or some of its subdirectories; this may
be suboptimal depending on your expectations (e.g., a read-only,
NFS-exported <code class="varname">PREFIX</code> with a need of per-machine
configuration of the provided packages).</p>
<p>In order to change the defaults, you can modify the
<code class="varname">PKG_SYSCONFBASE</code> variable (in
<a class="link" href="#mk.conf"><code class="filename">mk.conf</code></a>) to point to your preferred configuration
directory; some common examples include <code class="filename">/etc</code> or
<code class="filename">/etc/pkg</code>.</p>
<p>Furthermore, you can change this value on a per-package basis by
setting the <code class="varname">PKG_SYSCONFDIR.${PKG_SYSCONFVAR}</code> variable.
<code class="varname">PKG_SYSCONFVAR</code>'s value usually matches the name of the
package you would like to modify, that is, the contents of
<code class="varname">PKGBASE</code>.</p>
<p>Note that after changing these settings, you must rebuild and

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

a security audit of all packages installed on a system can take place.  To
do this, refer to the following two tools (installed as part of the

<a name="ufaq-cflags"></a>10.15. Why do some packages ignore my <code class="varname">CFLAGS</code>?</h2></div></div></div>
<p>When you add your own preferences to the
	<code class="varname">CFLAGS</code> variable in your
	<a class="link" href="#mk.conf"><code class="filename">mk.conf</code></a>, these flags are passed in
	environment variables to the <code class="filename">./configure</code>
	scripts and to <a class="citerefentry" href="https://man.NetBSD.org/NetBSD-9.1/i386/make.1"><span class="citerefentry"><span class="refentrytitle">make</span>(1)</span></a>. Some package authors ignore the
	<code class="varname">CFLAGS</code> from the environment variable by
	overriding them in the <code class="filename">Makefile</code>s of their
	package.</p>
<p>Currently there is no solution to this problem. If you
	really need the package to use your <code class="varname">CFLAGS</code>
	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">&#8220;<span class="quote">smart</span>&#8221;</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>To find out where the CFLAGS are ignored, add the following lines to <a class="link" href="#mk.conf"><code class="filename">mk.conf</code></a>:</p>
<pre class="programlisting">
CPPFLAGS+=              -Dpkgsrc___CPPFLAGS
CFLAGS+=                -Dpkgsrc___CFLAGS
CXXFLAGS+=              -Dpkgsrc___CXXFLAGS
</pre>
<p>Then run <span class="command"><strong>bmake show-all-configure show-all-build</strong></span>
to see whether the above flags are passed to the actual build
commands in general.</p>
<p>To find out whether the flags are passed to individual compiler
commands, have a look at the file <code class="filename">work/.work.log</code>. In
most cases, the flags from the original command lines (the lines starting
with <code class="literal">[*]</code>) are passed unmodified to the actual compiler
(the lines starting with <code class="literal">&lt;.&gt;</code>). If the flag is
missing from the actual compiler command, it must have been removed by

</div>
<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">
<div class="titlepage"><div><div><h2 class="title" style="clear: both">
<a name="components.Makefile"></a>12.1. <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 class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem"><p><code class="varname">DISTNAME</code> is the basename of the
    distribution file to be downloaded from the package's
    website.</p></li>
<li class="listitem"><p><code class="varname">PKGNAME</code> is the name of the
    package, as used by pkgsrc. You need to provide it if
    <code class="varname">DISTNAME</code> (which is the default) is not a good
    name for the package in pkgsrc or <code class="varname">DISTNAME</code> is not
    provided (no distribution file is required).  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 class="listitem">
<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">
archivers     cross         geography     meta-pkgs     security

<li class="listitem"><p><code class="varname">MASTER_SITES</code>,
    <code class="varname">DYNAMIC_MASTER_SITES</code>,
    <code class="varname">DIST_SUBDIR</code>, <code class="varname">EXTRACT_SUFX</code>
    and <code class="varname">DISTFILES</code> are discussed in detail in
    <a class="xref" href="#build.fetch" title="13.5. The fetch phase">Section 13.5, &#8220;The <span class="emphasis"><em>fetch</em></span> phase&#8221;</a>.</p></li>
</ul></div>
<p>The second section contains information about separately
  downloaded patches, if any.
  </p>
<div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem"><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 class="listitem"><p><code class="varname">PATCH_SITES</code>:
    Primary location(s) for distribution patch files (see
    <code class="varname">PATCHFILES</code> above) if not found locally.</p></li>
<li class="listitem"><p><code class="varname">PATCH_DIST_STRIP</code>:
    an argument to <a class="citerefentry" href="https://man.NetBSD.org/NetBSD-9.1/i386/patch.1"><span class="citerefentry"><span class="refentrytitle">patch</span>(1)</span></a> that sets the pathname strip count to
    help find the correct files to patch. It defaults to
    <span class="command"><strong>-p0</strong></span>.</p></li>
</ul></div>
<p>The third section contains the following variables.
  </p>
<div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem"><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="https://man.NetBSD.org/NetBSD-9.1/i386/send-pr.1"><span class="citerefentry"><span class="refentrytitle">send-pr</span>(1)</span></a>.
    Other developers may contact the <code class="varname">MAINTAINER</code>
    before making changes to the package, but are not required to
    do so. 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">&lt;<a class="email" href="mailto:pkgsrc-users@NetBSD.org">pkgsrc-users@NetBSD.org</a>&gt;</code>.</p></li>
<li class="listitem"><p><code class="varname">OWNER</code> should be used instead
    of <code class="varname">MAINTAINER</code> when you do not want other
    developers to update or change the package without contacting
    you first. A package Makefile should contain one of
    <code class="varname">MAINTAINER</code> or <code class="varname">OWNER</code>, but
    not both.  </p></li>
<li class="listitem"><p><code class="varname">HOMEPAGE</code> is a URL where users can
    find more information about the package.</p></li>
<li class="listitem"><p><code class="varname">COMMENT</code> is a one-line
    description of the package (should not include the package
    name).</p></li>
<li class="listitem"><p><code class="varname">LICENSE</code> indicates the license(s)
    applicable for the package. See <a class="xref" href="#handling-licenses" title="21.1.3. Handling licenses">Section 21.1.3, &#8220;Handling licenses&#8221;</a> for further details.</p></li>
</ul></div>
<p>Other variables that affect the build:
  </p>
<div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; "><li class="listitem">
<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="https://cdn.NetBSD.org/pub/pkgsrc/current/pkgsrc/lang/tcl/README.html" target="_top"><code class="filename">lang/tcl</code></a> and <a href="https://cdn.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
      <a class="link" href="#mk.conf"><code class="filename">mk.conf</code></a>, the first component of
      the host's name is attached to the directory name. If
      <code class="varname">OBJMACHINE</code> is defined, the platform name
      is attached, which might look like
      <code class="filename">work.i386</code> or
      <code class="filename">work.sparc</code>.</p>

<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. To provide maximum security, all distfiles are
  protected using three different message digest algorithms (SHA1,
  RMD160, SHA512), 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="12.3. patches/*">Section 12.3, &#8220;<code class="filename">patches/*</code>&#8221;</a>). These checksums ensure that patches
  are only applied intentionally and that they don't accidentally change,
  e.g. when merging different changes together. They also make sure that
  new patches are actually added to CVS and old ones are removed.
  Too see whether the patches and the <code class="filename">distinfo</code> file
  match, run <span class="command"><strong>pkglint</strong></span> after changing the patches.</p>
<p>To regenerate the <code class="filename">distinfo</code> file, use the
  <span class="command"><strong>make distinfo</strong></span> command.</p>
<p>Some packages have different sets of distfiles depending on
  the platform, for example <a href="https://cdn.NetBSD.org/pub/pkgsrc/current/pkgsrc/lang/openjdk8/README.html" target="_top"><code class="filename">lang/openjdk8</code></a>. These are kept in the same
  <code class="filename">distinfo</code> file and care should be taken when
  upgrading such a package to ensure distfile information is not
  lost.</p>

<p>Some packages don't work out-of-the box on the various
  platforms that are supported by pkgsrc. These packages need
  to be patched to make them work. The patch files can be
  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 alphabetic order.</p>
<div class="sect2">
<div class="titlepage"><div><div><h3 class="title">
<a name="components.patch.structure"></a>12.3.1. 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 class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem"><p>Patches for commonly known vulnerabilities should
  mention the vulnerability ID (CAN, CVE).</p></li>
<li class="listitem"><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>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">
<div class="titlepage"><div><div><h3 class="title">
<a name="components.patches.caveats"></a>12.3.2. 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="https://cdn.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>. The files in <code class="filename">patches</code>
  are replaced by new files, so carefully check if you want to take all
  the changes.</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="12.2. distinfo">Section 12.2, &#8220;<code class="filename">distinfo</code>&#8221;</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>path_to_file__with__underscores.c</code></em></code>.
  Many packages still use the previous convention
  <code class="filename">patch-<em class="replaceable"><code>[a-z][a-z]</code></em></code>,
  but new patches should be of the form containing the filename.
  <span class="command"><strong>mkpatches</strong></span> included in <a href="https://cdn.NetBSD.org/pub/pkgsrc/current/pkgsrc/pkgtools/pkgdiff/README.html" target="_top"><code class="filename">pkgtools/pkgdiff</code></a> takes care of the name
  automatically.</p>

<div class="sect2">
<div class="titlepage"><div><div><h3 class="title">
<a name="components.patches.sources"></a>12.3.3. 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=       ../../editors/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">$LOCALPATCHES</code> directory. The
    directory tree there is expected to have the same
    <span class="quote">&#8220;<span class="quote">category/package</span>&#8221;</span> structure as pkgsrc, and
    patches are expected to be stored inside these dirs (also
    known as <code class="filename">$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>12.3.4. 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 &mdash;
      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>Always, always, <span class="strong"><strong>always</strong></span>
      feed back any <span class="emphasis"><em>portability fixes</em></span> or
      improvements you do to a package to the mainstream developers.
      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.  Furthermore, any user that gets newer distfiles will get
      the fixes straight from the packaged code.</p>
<p>This generally involves cleaning up the patches
      (because sometimes the patches that are
      added to pkgsrc are quick hacks), filing bug reports in the
      appropriate trackers for the projects and working with the
      mainstream authors to accept your changes.  It is
      <span class="emphasis"><em>extremely important</em></span> that you do it so that
      the packages in pkgsrc are kept simple and thus further changes
      can be done without much hassle.</p>
<p>When you have done this, please add a URL to the upstream
      bug report to the patch comment.</p>

    prior to configuration or building, you can place these files here
    and use a <span class="command"><strong>${CP}</strong></span> command in the
    <span class="quote">&#8220;<span class="quote">post-extract</span>&#8221;</span> target to achieve this.</p>
<p>If you want to share files in this way with other

    to the other package's <code class="filename">files</code> directory,

<a name="build.intro"></a>13.1. 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 split 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>

<a name="build.prefix"></a>13.2. 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="12.3. patches/*">Section 12.3, &#8220;<code class="filename">patches/*</code>&#8221;</a> and <a class="xref" href="#fixes.libtool" title="21.3.1. Shared libraries - libtool">Section 21.3.1, &#8220;Shared libraries - libtool&#8221;</a> for more details.</p>
<p>When choosing which of these variables to use,
    follow the following rules:</p>
<div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem"><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">&#8220;<span class="quote">${PREFIX}</span>&#8221;</span>.</p></li>
<li class="listitem"><p><code class="varname">LOCALBASE</code> is where all non-X11 pkgs
	are installed.  If you need to construct a -I or -L argument
	to the compiler to find includes and libraries installed by
	another non-X11 pkg, use <span class="quote">&#8220;<span class="quote">${LOCALBASE}</span>&#8221;</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 class="listitem"><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">&#8220;<span class="quote">${X11BASE}</span>&#8221;</span>.</p></li>
<li class="listitem"><p>X11-based packages using imake must set
	<code class="varname">USE_IMAKE</code> to be installed correctly under
	<code class="varname">LOCALBASE</code>.</p></li>
<li class="listitem"><p>Within <code class="filename">${PREFIX}</code>, packages should
	install files according to <a class="citerefentry" href="https://man.NetBSD.org/NetBSD-9.1/i386/hier.7"><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>13.3. Directories used during the build process</h2></div></div></div>
<p>When building a package, various directories are 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 class="variablelist">
<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>
<dd><p>This is a pathname relative to
      <code class="varname">PKGSRCDIR</code> that points to the current
      package.</p></dd>
<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>
</dl></div>
<p>The <code class="varname">CREATE_WRKDIR_SYMLINK</code> definition takes either
    the value <span class="emphasis"><em>yes</em></span> or <span class="emphasis"><em>no</em></span> and defaults
    to <span class="emphasis"><em>no</em></span>. It indicates whether a symbolic link to the
    <code class="varname">WRKDIR</code> is to be created in the pkgsrc entry's directory.
    If users would like to have their pkgsrc trees behave in a
    read-only manner, then the value of
    <code class="varname">CREATE_WRKDIR_SYMLINK</code> should be set to
    <span class="emphasis"><em>no</em></span>.</p>

<div class="sect1">
<div class="titlepage"><div><div><h2 class="title" style="clear: both">
<a name="build.running"></a>13.4. 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>

<div class="titlepage"><div><div><h2 class="title" style="clear: both">
<a name="build.fetch"></a>13.5. 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">
<div class="titlepage"><div><div><h3 class="title">
<a name="build.fetch.what"></a>13.5.1. 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">${DEFAULT_DISTFILES}</code> and
      its value is <code class="literal">${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=      ${DEFAULT_DISTFILES} 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= \
https://www.somewhere.com/somehow/ \
https://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=   https://www.example.com/download.cgi?file=
</pre>
<p> The exception to this rule are URLs starting with a dash.
      In that case the URL is taken as is, fetched and the result
      stored under the name of the distfile. You can use this style
      for the case when the download URL style does not match the
      above common case. For example, if permanent download URL is a
      redirector to the real download URL, or the download file name
      is offered by an HTTP Content-Disposition header. In the
      following example, <code class="filename">foo-1.0.0.tar.gz</code> will be
      created instead of the default
      <code class="filename">v1.0.0.tar.gz</code>.</p>
<pre class="programlisting">
DISTNAME=       foo-1.0.0
MASTER_SITES=   -https://www.example.com/archive/v1.0.0.tar.gz
</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>

<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/pkgsrc/distfiles/%24%7BDIST_SUBDIR%7D" target="_top">ftp://ftp.NetBSD.org/pub/pkgsrc/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>13.5.2. 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">
${FETCH_CMD} ${FETCH_BEFORE_ARGS} ${site}${file} ${FETCH_AFTER_ARGS}
</pre>
<p>where <code class="literal">${site}</code> varies through
      several possibilities in turn: first,
      <code class="varname">MASTER_SITE_OVERRIDE</code> is tried, then the
      sites specified in either <code class="varname">SITES.file</code> if
      defined, else <code class="varname">MASTER_SITES</code> or
      <code class="varname">PATCH_SITES</code>, as applies, then finally the
      value of <code class="varname">MASTER_SITE_BACKUP</code>. The order of
      all except the first and the last can be optionally sorted
      by the user, via setting either
      <code class="varname">MASTER_SORT_RANDOM</code>, and
      <code class="varname">MASTER_SORT_AWK</code> or
      <code class="varname">MASTER_SORT_REGEX</code>.</p>
<p> The specific command and arguments used depend on the
      <code class="varname">FETCH_USING</code> parameter. The example above is
      for <code class="literal">FETCH_USING=custom</code>.</p>
<p>The distfiles mirror run by the NetBSD Foundation uses the
      <span class="emphasis"><em>mirror-distfiles</em></span> target to mirror the
      distfiles, if they are freely distributable.  Packages setting
      <code class="varname">NO_SRC_ON_FTP</code> (usually to
      <span class="quote">&#8220;<span class="quote">${RESTRICTED}</span>&#8221;</span>) will not have their distfiles
      mirrored.</p>

<div class="titlepage"><div><div><h2 class="title" style="clear: both">
<a name="build.checksum"></a>13.6. The <span class="emphasis"><em>checksum</em></span> phase</h2></div></div></div>
<p>After the distfile(s) are fetched, their checksum is
    generated and compared with the checksums stored in the
    distinfo file. If the checksums don't match, the build is
    aborted. This is to ensure the same distfile is used for
    building, and that the distfile wasn't changed, e.g. by some
    malign force, deliberately changed distfiles on the master
    distribution site or network lossage.</p>

<a name="build.extract"></a>13.7. The <span class="emphasis"><em>extract</em></span> phase</h2></div></div></div>
<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
    <code class="varname">EXTRACT_ONLY</code> variable to the list of those
    files.</p>
<p>Extracting the files is usually done by a little
    program, <code class="filename">mk/extract/extract</code>, which
    already knows how to extract various archive formats, so most
    likely you will not need to change anything here. But if you
    need, the following variables may help you:</p>
<div class="variablelist"><dl class="variablelist">
<dt><span class="term"><code class="varname">EXTRACT_OPTS_{BIN,LHA,PAX,RAR,TAR,ZIP,ZOO}</code></span></dt>
<dd><p>Use these variables to override the default
      options for an extract command, which are defined in
      <code class="filename">mk/extract/extract</code>.</p></dd>
<dt><span class="term"><code class="varname">EXTRACT_USING</code></span></dt>
<dd><p>This variable can be set to
      <code class="literal">bsdtar</code>, <code class="literal">gtar</code>, <code class="literal">nbtar</code>
      (which is the default value), <code class="literal">pax</code>, or an
      absolute pathname pointing to the command with which tar
      archives should be extracted.  It is preferred to choose bsdtar over gtar
      if NetBSD's pax-as-tar is not good enough.</p></dd>
</dl></div>
<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>
<p>And if that still does not suffice, you can override the
    <code class="varname">do-extract</code> target in the package
    Makefile.</p>

<p>Most pieces of software need information on the header
    files, system calls, and library routines which are available
    on the platform they run on. The process of determining this
    information is known as configuration, and is usually
    automated. In most cases, a script is supplied with the
    distfiles, and its invocation results in generation of header
    files, Makefiles, etc.</p>
<p>If the package contains a configure script, this can be
    invoked by setting <code class="varname">HAS_CONFIGURE</code> to
    <span class="quote">&#8220;<span class="quote">yes</span>&#8221;</span>. If the configure script is a GNU autoconf
    script, you should set <code class="varname">GNU_CONFIGURE</code> to

</div>
<p>When you find a package that is not yet in pkgsrc, you
most likely have a URL from where you can download the source
code. Starting with this URL, creating a package involves only a
few steps.</p>
<div class="procedure"><ol class="procedure" type="1">
<li class="step"><p>In your <a class="link" href="#mk.conf"><code class="filename">mk.conf</code></a>, set <code class="code">PKG_DEVELOPER=yes</code> to
enable the basic quality checks.</p></li>
<li class="step">
<p>Install the package <a href="https://cdn.NetBSD.org/pub/pkgsrc/current/pkgsrc/meta-pkgs/pkg_developer/README.html" target="_top"><code class="filename">meta-pkgs/pkg_developer</code></a>, which among others will
install the utilities <span class="command"><strong>url2pkg</strong></span>,
<span class="command"><strong>pkglint</strong></span>, <span class="command"><strong>pkgvi</strong></span> and
<span class="command"><strong>mkpatches</strong></span>:</p>
<pre class="screen"><code class="prompt">$</code> <strong class="userinput"><code>cd /usr/pkgsrc</code></strong>
<code class="prompt">$</code> <strong class="userinput"><code>(cd meta-pkgs/pkg_developer &amp;&amp; bmake update)</code></strong></pre>
</li>
<li class="step">
<p>Choose one of the top-level directories as the 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>
<pre class="screen"><code class="prompt">$</code> <strong class="userinput"><code>mkdir <em class="replaceable"><code>category</code></em>/<em class="replaceable"><code>package</code></em></code></strong>
<code class="prompt">$</code> <strong class="userinput"><code>cd <em class="replaceable"><code>category</code></em>/<em class="replaceable"><code>package</code></em></code></strong></pre>
</li>
<li class="step">
<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>
<pre class="screen"><code class="prompt">$</code> <strong class="userinput"><code>url2pkg <em class="replaceable"><code>https://www.example.org/packages/package-1.0.tar.gz</code></em></code></strong></pre>
</li>
<li class="step">
<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, it must be
created first. The <code class="filename">buildlink3.mk</code> file makes sure
that the package's include files and libraries are provided.</p>
<p>If you just need binaries from a package, 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">TOOL_DEPENDS</code> or <code class="varname">BUILD_DEPENDS</code>
instead of <code class="varname">DEPENDS</code>.
The difference between <code class="varname">TOOL_DEPENDS</code> and
<code class="varname">BUILD_DEPENDS</code> occurs when cross-compiling:
<code class="varname">TOOL_DEPENDS</code> are <span class="emphasis"><em>native</em></span>
packages, i.e. packages for the architecture where the package
is built;
<code class="varname">BUILD_DEPENDS</code> are <span class="emphasis"><em>target</em></span>
packages, i.e. packages for the architecture for which the package
is built. There is also <code class="varname">TEST_DEPENDS</code>, which is used
to specify a dependency used only for testing the resulting package
built, using the upstream project's included test suite.
Your package may then look like this:</p>
<pre class="programlisting">
[...]

TOOL_DEPENDS+=  libxslt-[0-9]*:../../textproc/libxslt
DEPENDS+=       screen-[0-9]*:../../misc/screen
DEPENDS+=       screen&gt;=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 class="step"><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">&#8220;<span class="quote">good</span>&#8221;</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 class="step"><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="14.1. Common types of packages">Section 14.1, &#8220;Common types of packages&#8221;</a>. After you have followed the instructions
over there, you can hopefully continue here.</p></li>
<li class="step"><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 class="step">
<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 21. Making your package work">Chapter 21, <i>Making your package work</i></a>.</p>
<p>If the extracted files from the package need to be fixed, run multiple rounds of these commands:</p>
<pre class="screen"><code class="prompt">$</code> <strong class="userinput"><code>make</code></strong>
<code class="prompt">$</code> <strong class="userinput"><code>pkgvi ${WRKSRC}/some/file/that/does/not/compile</code></strong>
<code class="prompt">$</code> <strong class="userinput"><code>mkpatches</code></strong>
<code class="prompt">$</code> <strong class="userinput"><code>make mps</code></strong>
<code class="prompt">$</code> <strong class="userinput"><code>make clean</code></strong></pre>
</li>
<li class="step"><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 class="step"><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
&gt;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 class="step"><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 class="step"><p>When you ran <span class="command"><strong>bmake install</strong></span>, the package
had 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 class="step"><p>Run <span class="command"><strong>bmake package</strong></span> to create a binary
package from the set of installed files.</p></li>
<li class="step"><p>Run <span class="command"><strong>bmake clean update</strong></span> to run everything
from above again in a single step, making sure that the PLIST is correct
and the whole package is created as intended.</p></li>
<li class="step"><p>Run <span class="command"><strong>pkglint</strong></span> to see if there's anything left to do.</p></li>
<li class="step"><p>Commit the package to pkgsrc-wip or main pkgsrc; see <a class="xref" href="#submit" title="Chapter 23. Submitting and Committing">Chapter 23, <i>Submitting and Committing</i></a>.</p></li>

<div class="titlepage"><div><div><h3 class="title">
<a name="creating.python-module"></a>14.1.2. Python modules and programs</h3></div></div></div>
<p>Python modules and programs packages are easily created using a
set of predefined variables.</p>
<p>
If some Python versions are not supported by the software, set the
<code class="varname">PYTHON_VERSIONS_INCOMPATIBLE</code> variable to the Python versions
that are not supported, e.g.
</p>
<pre class="programlisting">
PYTHON_VERSIONS_INCOMPATIBLE=       27
</pre>
<p>
If the packaged software is a Python module, include one of
<code class="filename">../../lang/python/egg.mk</code>,
<code class="filename">../../lang/python/distutils.mk</code>, or
<code class="filename">../../lang/python/extension.mk</code>.</p>
<p>Most Python packages use either <span class="quote">&#8220;<span class="quote">distutils</span>&#8221;</span> or
easy-setup/setuptools (<span class="quote">&#8220;<span class="quote">eggs</span>&#8221;</span>).
If the packaged software is using setuptools, you only need
to include <span class="quote">&#8220;<span class="quote"><code class="filename">../../lang/python/egg.mk</code></span>&#8221;</span>.
Otherwise, if the software uses <span class="quote">&#8220;<span class="quote">distutils</span>&#8221;</span>, include 
<span class="quote">&#8220;<span class="quote"><code class="filename">../../lang/python/distutils.mk</code></span>&#8221;</span>,
so pkgsrc will use this framework.
<span class="quote">&#8220;<span class="quote">distutils</span>&#8221;</span> uses a script called <code class="filename">setup.py</code>;
if the <span class="quote">&#8220;<span class="quote">distutils</span>&#8221;</span> driver is not called
<code class="filename">setup.py</code>, set the <code class="varname">PYSETUP</code> variable
to the name of the script.</p>
<p>Either way, the package directory should be called
<span class="quote">&#8220;<span class="quote">py-software</span>&#8221;</span> and <code class="varname">PKGNAME</code> should be set to
<span class="quote">&#8220;<span class="quote">${PYPKGPREFIX}-${DISTNAME}</span>&#8221;</span>, e.g.
</p>
<pre class="programlisting">
DISTNAME=   foopymodule-1.2.10
PKGNAME=    ${PYPKGPREFIX}-${DISTNAME}
</pre>
<p>If it is an application, include
<span class="quote">&#8220;<span class="quote"><code class="filename">../../lang/python/application.mk</code></span>&#8221;</span>.
In order to correctly set the path to the Python interpreter, use the
<code class="varname">REPLACE_PYTHON</code> variable and set it to the list of files
(paths relative to <code class="varname">WRKSRC</code>) that must be corrected.
For example:
</p>
<pre class="programlisting">
REPLACE_PYTHON=   *.py
</pre>
<p>Some Python modules have separate distributions for Python-2.x
and Python-3.x support. In pkgsrc this is handled by the
<code class="filename">versioned_dependencies.mk</code> file. Set
<code class="varname">PYTHON_VERSIONED_DEPENDENCIES</code> to the list of
packages that should be depended upon and include
<span class="quote">&#8220;<span class="quote"><code class="filename">../../lang/python/versioned_dependencies.mk</code></span>&#8221;</span>,
then the pkgsrc infrastructure will depend on the appropriate package
version. For example:
</p>
<pre class="programlisting">
PYTHON_VERSIONED_DEPENDENCIES=dialog
</pre>
<p>
Look inside <code class="filename">versioned_dependencies.mk</code> for a list
of supported packages.</p>

<p>Simple R packages from <a class="ulink" href="https://cran.r-project.org/web/packages/available_packages_by_name.html" target="_top">CRAN</a>
are handled automatically by <span class="command"><strong>R2pkg</strong></span>, which is
available in <a href="https://cdn.NetBSD.org/pub/pkgsrc/current/pkgsrc/pkgtools/R2pkg/README.html" target="_top"><code class="filename">pkgtools/R2pkg</code></a>.
Individual packages (and optionally their dependencies) may be created
and updated.  R packages generally follow the same form, and most of
the relevant information needed is contained in a
<code class="filename">DESCRIPTION</code> file as part of each R package on
<a class="ulink" href="https://cran.r-project.org/web/packages/available_packages_by_name.html" target="_top">CRAN</a>.
Consequently, <span class="command"><strong>R2pkg</strong></span> downloads that information and
creates or updates a package in the canonical form.  The resulting
package should be reviewed for correctness.</p>

<div class="titlepage"><div><div><h3 class="title">

<p>TeXlive packages from <a class="ulink" href="https://www.ctan.org/" target="_top">CTAN</a> are handled automatically by
<span class="command"><strong>texlive2pkg</strong></span>, which is available in <a href="https://cdn.NetBSD.org/pub/pkgsrc/current/pkgsrc/pkgtools/texlive2pkg/README.html" target="_top"><code class="filename">pkgtools/texlive2pkg</code></a>.</p>
<p>If the TeXlive package name is not known, it may be useful to
search <a class="ulink" href="https://www.ctan.org/" target="_top">CTAN</a>.  A
<span class="quote">&#8220;<span class="quote">Contained in</span>&#8221;</span> field on the package page typically
identifies the basename of the package file in the <a class="ulink" href="https://www.ctan.org/tex-archive/systems/texlive/tlnet/archive" target="_top">TeXlive
archive</a>.</p>
<p>If the TeXlive package name is known, download the files from
the <a class="ulink" href="https://www.ctan.org/tex-archive/systems/texlive/tlnet/archive" target="_top">TeXlive
archive</a>.  For package <code class="filename">foo</code>, you will need
to download <code class="filename">foo.tar.xz</code>.  Most TeXlive packages
also have associated documentation packages, so download
<code class="filename">foo.doc.tar.xz</code> at the same time.  These files
should be placed in the appropriate category directory, which is often
but not always <code class="filename">print</code>.  Then run the following
command in the category directory.</p>
<pre class="programlisting">
texlive2pkg foo.tar.xz foo.doc.tar.xz
</pre>
<p>This will create two packages, <code class="filename">tex-foo</code> and
<code class="filename">tex-foo-doc</code>.  Be sure to check that both packages
are correct.</p>
<p>Finally, <a class="ulink" href="https://www.ctan.org/" target="_top">CTAN</a>
currently does not include version information in package filenames
and changes their contents periodically when updates occur.
Consequently, pkgsrc avoids downloading distfiles directly from <a class="ulink" href="https://www.ctan.org/" target="_top">CTAN</a> and instead relies on the
pkgsrc archives.  For each new or updated TeXlive package, e.g., the
main one and the corresponding documentation, upload the distfiles
with the following command in each package directory.</p>
<pre class="programlisting">
make upload-distfiles

<p>Looking at the file <code class="filename">pkgsrc/doc/TODO</code>, I saw
that the <span class="quote">&#8220;<span class="quote">nvu</span>&#8221;</span> package has not yet been imported into

<pre class="programlisting">
<code class="prompt">$</code> mkdir 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">&#8220;<span class="quote">sources</span>&#8221;</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>

this is a workaround to prevent CVS expanding to the filename of the

<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>
<pre class="programlisting">

<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">&#8220;<span class="quote">perl</span>&#8221;</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">&#8220;<span class="quote">tools</span>&#8221;</span> phase, I need to build the package
from scratch.</p>

<code class="varname">USE_TOOLS</code> line and tried again (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">&#8220;<span class="quote">2</span>&#8221;</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 &amp;&amp; bmake</strong></span>, the answer
was:</p>
<pre class="programlisting">

*** 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">&#8220;<span class="quote">every package
prefers GNOME 2</span>&#8221;</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>
<pre class="programlisting">

[...]
</pre>
<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="https://cdn.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>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="https://man.NetBSD.org/NetBSD-9.1/i386/make.1"><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 and shell
  commands. Among these shell commands may even be more complex ones
  like <a class="citerefentry" href="https://man.NetBSD.org/NetBSD-9.1/i386/awk.1"><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>
<div class="sect1">
<div class="titlepage"><div><div><h2 class="title" style="clear: both">

<p>When you are creating a file as a
    target of a rule, always write the data to a temporary file first
    and finally rename that file. Otherwise there might occur an error
    in the middle of generating the file, and when the user runs
    <a class="citerefentry" href="https://man.NetBSD.org/NetBSD-9.1/i386/make.1"><span class="citerefentry"><span class="refentrytitle">make</span>(1)</span></a> for the second time, the file exists and will not be
    regenerated properly. Example:</p>
<pre class="programlisting">
wrong:
        @echo "line 1" &gt; ${.TARGET}
        @echo "line 2" &gt;&gt; ${.TARGET}
        @false

correct:
        @echo "line 1" &gt; ${.TARGET}.tmp
        @echo "line 2" &gt;&gt; ${.TARGET}.tmp
        @false
        @mv ${.TARGET}.tmp ${.TARGET}

<p>When you run <span class="command"><strong>make wrong</strong></span> twice, the file
    <code class="filename">wrong</code> will exist, although there was an error
    message in the first run. On the other hand, running <span class="command"><strong>make
    correct</strong></span> gives an error message twice, as expected.</p>
<p>You might remember that <a class="citerefentry" href="https://man.NetBSD.org/NetBSD-9.1/i386/make.1"><span class="citerefentry"><span class="refentrytitle">make</span>(1)</span></a> sometimes removes
    <code class="literal">${.TARGET}</code> in case of error, but this only
    happens when it is interrupted, for example by pressing
    <code class="literal">Ctrl+C</code>. This does <span class="emphasis"><em>not</em></span> happen
    when one of the commands fails (like <a class="citerefentry" href="https://man.NetBSD.org/NetBSD-9.1/i386/false.1"><span class="citerefentry"><span class="refentrytitle">false</span>(1)</span></a> above).</p>

<div class="titlepage"><div><div><h2 class="title" style="clear: both">
<a name="makefile.variables"></a>15.2. <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 <code class="code">=</code>,
    <code class="code">+=</code>, <code class="code">?=</code>, <code class="code">:=</code> and
    <code class="code">!=</code>, which are described in the <a class="citerefentry" href="https://man.NetBSD.org/NetBSD-9.1/i386/make.1"><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 <code class="code">#</code> and
    the backslash character <code class="code">\</code> are handled specially. If a
    backslash is the last character in a line, that backslash is removed
    from the line and the line continues with the next line of the file.</p>
<p>The <code class="code">#</code> character starts a comment that reaches
    until the end of the line. To get an actual <code class="code">#</code> character,
    such as in a URL, write <code class="code">\#</code> instead.</p>
<p>The evaluation of variables either happens immediately or lazy.
    It happens immediately when the variable occurs on the right-hand
    side of the <code class="code">:=</code> or the <code class="code">!=</code> operator, in a
    <code class="varname">.if</code> condition or a <code class="varname">.for</code> loop.
    In the other cases, it is evaluated lazily.</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, double quotes and single quotes are
    interpreted as delimiters, just like in <a class="citerefentry" href="https://man.NetBSD.org/NetBSD-9.1/i386/sh.1"><span class="citerefentry"><span class="refentrytitle">sh</span>(1)</span></a>.</p>

modifier.</p>
<p>When adding another list to a list (example 2), it must not be

        env ${EXAMPLE_ENV} sh -c 'echo "$$string"; echo "$$x"'   # 4
</pre>
<p>Example 1 leads to a syntax error in the shell, as the characters
are just copied.</p>
<p>Example 2 quotes the string so that the shell interprets it
correctly. But the echo command may additionally interpret strings with a
leading dash or those containing backslashes.</p>
<p>Example 3 can handle arbitrary strings, since <a class="citerefentry" href="https://man.NetBSD.org/NetBSD-9.1/i386/printf.1"><span class="citerefentry"><span class="refentrytitle">printf</span>(1)</span></a> only
interprets the format string, but not the next argument. The trailing
single quotes handle the case when the string is empty. In that case, the
:Q modifier would result in an empty string too, which would then be
skipped by the shell. For <a class="citerefentry" href="https://man.NetBSD.org/NetBSD-9.1/i386/printf.1"><span class="citerefentry"><span class="refentrytitle">printf</span>(1)</span></a> this doesn't make a difference,
but other programs may care.</p>
<p>In example 4, the <code class="varname">EXAMPLE_ENV</code> does not
need to be quoted because the quoting has already been done
when adding elements to the list.</p>

trailing whitespace, use the <code class="code">:M</code> modifier, as in the
following example:</p>
<pre class="programlisting">
CPPFLAGS=               # empty
CPPFLAGS+=              -Wundef -DPREFIX=\"${PREFIX}\"
CPPFLAGS+=              ${MY_CPPFLAGS}

CONFIGURE_ARGS+=        CPPFLAGS=${CPPFLAGS:M*:Q}

all:
        echo x${CPPFLAGS:Q}x            # leading and trailing whitespace
        echo x${CONFIGURE_ARGS:Q}x      # properly trimmed
</pre>
<p>In this example, <code class="varname">CPPFLAGS</code> has both leading and
trailing whitespace because the <code class="code">+=</code> operator always adds a
space.</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>

<p>Options that enable similar features in different packages (like
optional support for a library) should use a common name in all

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

(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

<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

typical example looks like this:</p>

</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

<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">TOOL_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">
<div class="titlepage"><div><div><h2 class="title" style="clear: both">
<a name="pkgsrc-tools"></a>17.1. Tools for pkgsrc builds</h2></div></div></div>
<p>The default set of tools used by pkgsrc is defined in

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

<pre class="programlisting">

<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 class="orderedlist" type="1">
<li class="listitem"><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 class="listitem"><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>

<a name="converting-to-buildlink3"></a>18.1. Converting packages to use buildlink3</h2></div></div></div>
<p>The process of converting packages to use the buildlink3
    framework (<span class="quote">&#8220;<span class="quote">bl3ifying</span>&#8221;</span>) is fairly straightforward.
    The things to keep in mind are:</p>
<div class="orderedlist"><ol class="orderedlist" type="1">
<li class="listitem"><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">${WRKDIR}/.work.log</code> to see if the
	wrappers are being invoked.</p></li>
<li class="listitem"><p>Don't override <code class="varname">PREFIX</code> from within
	the package Makefile, e.g. Java VMs, standalone shells,
	etc., because the code to symlink files into
	<code class="filename">${BUILDLINK_DIR}</code> looks for files
	relative to <span class="quote">&#8220;<span class="quote">pkg_info -qp <em class="replaceable"><code>pkgname</code></em></span>&#8221;</span>.
	</p></li>
<li class="listitem"><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&gt;=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&gt;=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 class="itemizedlist" style="list-style-type: disc; ">

<p>This section can additionally include any

      Including these <code class="filename">buildlink3.mk</code> files
      means that the headers and libraries for these

      <code class="filename">${BUILDLINK_DIR}</code>
      whenever the <em class="replaceable"><code>pkg</code></em>
      <code class="filename">buildlink3.mk</code>

<p>When providing a <code class="filename">buildlink3.mk</code> and
      including other <code class="filename">buildlink3.mk</code> files in it,
      please only add necessary ones, i.e., those whose libraries or
      header files are automatically exposed when the package is
      use.</p>
<p>In particular, if only an executable
      (<code class="filename">bin/foo</code>) is linked against a library, that
      library does not need to be propagated in the
      <code class="filename">buildlink3.mk</code> file.</p>
<p>The following steps should help you decide if a

      </p>
<div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem"><p>Look at the installed header files: What
	headers do they include? The packages providing these files
	must be buildlinked.</p></li>
<li class="listitem"><p>Run <code class="filename">ldd</code> on all installed
	libraries and look against what other libraries they link.
	Some of the packages providing these probably need to be
	buildlinked; however, it's not automatic, since e.g. GTK on
	some systems pulls in the X libraries, so they will show up in
	the <code class="filename">ldd</code> output, while on others (like OS
	X) it won't. <code class="filename">ldd</code> output can thus only be
	used as a hint.</p></li>

      in <code class="filename">buildlink3.mk</code> files</h3></div></div></div>
<p>Both variables set lower bounds for a version of this package.
      The two variables differ in that one describes source
      compatibility (API) and the other binary compatibility (ABI).
      The difference is that a change in the API breaks compilation of
      programs while changes in the ABI stop compiled programs from
      running.</p>
<p>The
      <code class="varname">BUILDLINK_API_DEPENDS.<em class="replaceable"><code>pkg</code></em></code>
      variable in a <code class="filename">buildlink3.mk</code> should be
      changed very rarely.  (One possible scenario: If all packages
      using this package need a higher version than defined in the
      <code class="filename">buildlink3.mk</code>,
      <code class="varname">BUILDLINK_API_DEPENDS.<em class="replaceable"><code>pkg</code></em></code>
      could be updated to that higher version.)</p>
<p>On the other hand, changes to
      <code class="varname">BUILDLINK_ABI_DEPENDS.<em class="replaceable"><code>pkg</code></em></code>
      are more common.  The variable will need to be updated every
      time the major version of one of its shared libraries is changed,
      or any other change where a binary built against the previous
      version of the package will not run against the new version any
      longer.</p>
<p>In such a case, the package's
      <code class="varname">BUILDLINK_ABI_DEPENDS.<em class="replaceable"><code>pkg</code></em></code>
      must be increased to require the new package version.  Then the
      <code class="varname">PKGREVISION</code> of all packages
      <em class="replaceable"><code>foo</code></em> that depend on this package need
      to be increased, and if they have
      <code class="filename">buildlink3.mk</code> files,
      <code class="varname">BUILDLINK_ABI_DEPENDS.<em class="replaceable"><code>foo</code></em></code>
      in their <code class="filename">buildlink3.mk</code> files must be
      increased to the new version as well. This is required so that a
      package will pull in the versions of the packages that use the
      new ABI and that the packages' <code class="varname">PKGREVISION</code>s
      uniquely identify the packages built against the new ABI. The
      <a href="https://cdn.NetBSD.org/pub/pkgsrc/current/pkgsrc/pkgtools/revbump/README.html" target="_top"><code class="filename">pkgtools/revbump</code></a> package can
      help with these updates.</p>
<p>See <a class="xref" href="#dependencies" title="21.1.5. Handling dependencies">Section 21.1.5, &#8220;Handling dependencies&#8221;</a> for more information
      about dependencies on other packages, including the
      <code class="varname">BUILDLINK_API_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>
      in a <code class="filename">buildlink3.mk</code> file 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>

<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

<p>The second section sets

      <code class="filename">builtin.mk</code> files.  The code in this

	<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
	<code class="varname">PREFER_NATIVE</code>.  For example, to require
	using pkgsrc versions of software for all but the most basic
      bits on a NetBSD system, you can set:</p>
<pre class="programlisting">
PREFER_PKGSRC=  yes
PREFER_NATIVE=  getopt skey tcp_wrappers
</pre>
<p>A package <span class="emphasis"><em>must</em></span> have a
      <code class="filename">builtin.mk</code>
      file to be listed in <code class="varname">PREFER_NATIVE</code>,
      otherwise it is simply ignored in that list.</p>
<p><code class="varname">PREFER_PKGSRC</code> and
      <code class="varname">PREFER_NATIVE</code> should be set during bootstrap
      to ensure that the bootstrap process does not use inapropriate
      native tools as dependencies for core packages.

</p>
<pre class="screen">
<code class="prompt">#</code> <strong class="userinput"><code>./bootstrap --prefer-pkgsrc yes --prefer-native openssl</code></strong>
</pre>
<p>

      Switching between settings globally at a later date can introduce
      complications with dependency resolution. This is caused by packages
      built with the opposite preference being installed alongside each
      other.  Hence, any changes to these variables after bootstrap will
      necessitate rebuilding all packages depending on one whose preference
      has been changed.  This is not trivial and should be avoided.</p>
<p>When using pkgsrc on Linux systems, there is high risk of
      "leakage", where programs installed by pkgsrc may inadvertently use a
      command or library not installed by pkgsrc, e.g. those installed by
      yum or apt.  Such foreign dependencies may be installed, removed, or
      upgraded to a version incompatible with the pkgsrc package at any
      time, causing pkgsrc packages to subsequently malfunction.  Pkgsrc
      cannot prevent this, as it has no control over other package managers.
      Another potential problem is that under Redhat Enterprise and related
      Linux systems, yum packages are only patched and never upgraded, so
      eventually they may become too outdated for use by pkgsrc.  Even
      intentionally using foreign dependencies, not considered leakage, can
      lead to these problems, so it is generally discouraged.  In order to
      minimize such problems, PREFER_PKGSRC defaults to "yes" on Linux systems.
      This ensures that pkgsrc is aware of any changes to dependency packages
      and can rebuild or upgrade the entire dependency tree as needed.  This
      default can be overridden by setting --prefer-pkgsrc to "no" or a list of
      packages, or by setting --prefer-native to "yes".</p>

<p>You can use the <span class="command"><strong>make print-PLIST</strong></span> command
    to output a PLIST that matches any new files since the package

<a name="plist.misc"></a>19.4. 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 class="variablelist">
<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">&#8220;<span class="quote"><code class="varname">${MACHINE_ARCH}</code></span>&#8221;</span> will be
	  replaced by what <span class="command"><strong>uname -p</strong></span> gives. The
	  same is done if the string
	  <code class="varname">${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">&#8220;<span class="quote"><code class="varname">$ARCH</code></span>&#8221;</span> that
	    was replaced by the output of <span class="command"><strong>uname
	    -m</strong></span>, but that's no longer supported and has
	    been removed.</p>
</div>
</dd>
<dt><span class="term"><code class="varname">${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 class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem"><p><code class="varname">${OPSYS}</code> - output of <span class="quote">&#8220;<span class="quote"><span class="command"><strong>uname -s</strong></span></span>&#8221;</span></p></li>

</dd>
</dl></div>
<p>For a list of values which are replaced by
    default, the output of <span class="command"><strong>make help topic=PLIST_SUBST</strong></span> as
well as searching the <code class="filename">pkgsrc/mk</code> directory with <span class="command"><strong>grep</strong></span> for
<code class="varname">PLIST_SUBST</code> should help.</p>
<p>If you want to change other variables not listed above, you
    can add variables and their expansions to this variable in the
    following way, similar to <code class="varname">MESSAGE_SUBST</code> (see <a class="xref" href="#components.optional" title="12.5. Optional files">Section 12.5, &#8220;Optional files&#8221;</a>):</p>
<pre class="programlisting">
PLIST_SUBST+=   SOMEVAR="somevalue"

<p>This replaces all occurrences of <span class="quote">&#8220;<span class="quote">${SOMEVAR}</span>&#8221;</span>
    in the <code class="filename">PLIST</code> with
    <span class="quote">&#8220;<span class="quote">somevalue</span>&#8221;</span>.</p>
<p>The <code class="varname">PLIST_VARS</code> variable can be used to simplify
    the common case of conditionally including some
    <code class="filename">PLIST</code> entries. It can be done by adding
    <code class="literal"><code class="varname">PLIST_VARS</code>+=foo</code> and
    setting the corresponding <code class="varname">PLIST.foo</code> variable
    to <code class="literal">yes</code> if the entry should be included.
    This will substitute <span class="quote">&#8220;<span class="quote"><code class="varname">${PLIST.foo}</code></span>&#8221;</span>
    in the <code class="filename">PLIST</code> with either
    <span class="quote">&#8220;<span class="quote"><code class="literal">""</code></span>&#8221;</span> or
    <span class="quote">&#8220;<span class="quote"><code class="literal">"@comment "</code></span>&#8221;</span>.
    For example, in <code class="filename">Makefile</code>:</p>
<pre class="programlisting">
PLIST_VARS+=    foo

<p>A <span class="quote">&#8220;<span class="quote">shared directory</span>&#8221;</span> is a directory where
    multiple (and unrelated) packages install files.  These
    directories were problematic because you had to add special

    centralized package handle them.</p>
<p>In pkgsrc, it is now easy: Each package should create

    will remove any directories left empty after uninstalling a
    package.</p>
<p>If a package needs an empty directory to work, create
    the directory during installation as usual, and also add an
    entry to the PLIST:

<p>This chapter describes the framework known as

<div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem"><p>Generic installation and manipulation of directories and files
    outside the pkgsrc-handled tree, <code class="varname">LOCALBASE</code>.</p></li>

<li class="listitem"><p>Registration of system shells.</p></li>
<li class="listitem"><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">
<div class="titlepage"><div><div><h2 class="title" style="clear: both">
<a name="files-and-dirs-outside-prefix"></a>20.1. 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">
<div class="titlepage"><div><div><h3 class="title">
<a name="dirs-outside-prefix"></a>20.1.1. 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 class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem">
<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.  Example:</p>
<pre class="programlisting">
MAKE_DIRS+=             ${VARBASE}/foo/private
</pre>
</li>
<li class="listitem">
<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 \
                        ${REAL_ROOT_USER} ${REAL_ROOT_GROUP} 0700
</pre>
<p>The difference between the two is exactly the same as their
    non-<code class="varname">PERMS</code> counterparts.</p>
</li>
</ul></div>
</div>
<div class="sect2">
<div class="titlepage"><div><div><h3 class="title">
<a name="files-outside-prefix"></a>20.1.2. 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 class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem">
<p><code class="varname">CONF_FILES</code> and
    <code class="varname">REQD_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>

<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>

<a name="conf-files-sysconfdir"></a>20.2.1. 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 class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem"><p><code class="varname">PKG_SYSCONFBASE</code>: The configuration's root
    directory.  Defaults to <code class="filename">${PREFIX}/etc</code> although it may
    be overridden by the user to point to his preferred location (e.g.,
    <code class="filename">/etc</code>, <code class="filename">/etc/pkg</code>, etc.).
    Packages must not use it directly.</p></li>
<li class="listitem">
<p><code class="varname">PKG_SYSCONFSUBDIR</code>: A subdirectory of
    <code class="varname">PKG_SYSCONFBASE</code> under which the configuration files
    for the package being built shall be installed.  The definition of this
    variable only makes sense in the package's
    <code class="filename">Makefile</code> (i.e., it is not user-customizable).</p>
<p>As an example, consider the Apache package,
    <a href="https://cdn.NetBSD.org/pub/pkgsrc/current/pkgsrc/www/apache24/README.html" target="_top"><code class="filename">www/apache24</code></a>, which places its
    configuration files under the
    <code class="filename">httpd/</code> subdirectory of
    <code class="varname">PKG_SYSCONFBASE</code>.  This should be set in the package
    Makefile.</p>
</li>
<li class="listitem"><p><code class="varname">PKG_SYSCONFVAR</code>: Specifies the name of the
    variable that holds this package's configuration directory (if
    different from <code class="varname">PKG_SYSCONFBASE</code>).  It defaults to
    <code class="varname">PKGBASE</code>'s value, and is always prefixed with
    <code class="literal">PKG_SYSCONFDIR</code>.</p></li>
<li class="listitem"><p><code class="varname">PKG_SYSCONFDIR.${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 class="orderedlist" type="1">
<li class="listitem"><p>If <code class="varname">PKG_SYSCONFDIR.${PKG_SYSCONFVAR}</code> is set,
    its value is used.</p></li>
<li class="listitem"><p>If the previous variable is not defined but
    <code class="varname">PKG_SYSCONFSUBDIR</code> is set in the package's
    <code class="filename">Makefile</code>, the resulting value is
    <code class="filename">${PKG_SYSCONFBASE}/${PKG_SYSCONFSUBDIR}</code>.</p></li>
<li class="listitem"><p>Otherwise, it is set to
    <code class="filename">${PKG_SYSCONFBASE}</code>.</p></li>
</ol></div>
<p>It is worth mentioning that <code class="filename">${PKG_SYSCONFDIR}</code> is
automatically added to <code class="filename">OWN_DIRS</code>.  See <a class="xref" href="#dirs-outside-prefix" title="20.1.1. Directory manipulation">Section 20.1.1, &#8220;Directory manipulation&#8221;</a> what this means.  This does not apply to
subdirectories of <code class="filename">${PKG_SYSCONFDIR}</code>, they still have to
be created with OWN_DIRS or MAKE_DIRS.</p>

<a name="conf-files-configure"></a>20.2.2. 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=${PKG_SYSCONFDIR}
</pre>
<p>Note that this specifies where the package has to <span class="emphasis"><em>look
for</em></span> its configuration files, not where they will be originally
installed (although the difference is never explicit,
unfortunately).</p>
</div>
<div class="sect2">
<div class="titlepage"><div><div><h3 class="title">
<a name="conf-files-patching"></a>20.2.3. Patching installations</h3></div></div></div>
<p>As said before, pkginstall automatically handles configuration files.
This means that <span class="strong"><strong>the packages themselves must not
touch the contents of <code class="filename">${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="20.1.2. File manipulation">Section 20.1.2, &#8220;File manipulation&#8221;</a> for information
about their syntax and their purpose.  Here is an example, taken from the
<a href="https://cdn.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>

<a name="rcd-scripts"></a>20.3. 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="20.1. Files and directories outside the installation prefix">Section 20.1, &#8220;Files and directories outside the installation prefix&#8221;</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 class="orderedlist" type="1">
<li class="listitem"><p>Store the script inside <code class="filename">${FILESDIR}</code>, with
    the <code class="literal">.sh</code> suffix appended.  Considering the
    <a href="https://cdn.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 class="listitem">
<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 class="orderedlist" type="1">
<li class="listitem"><p>Process the file found in the files directory applying all the
    substitutions described in the <code class="filename">FILES_SUBST</code>

<li class="listitem"><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 class="listitem"><p>Add code to the installation scripts to copy the startup script

<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>,<code class="literal">build</code>, or
<code class="literal">pre-install</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>

<p>Packages that install system shells should register them in the shell

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="https://cdn.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">&#8220;<span class="quote">ttf</span>&#8221;</span>,
<span class="quote">&#8220;<span class="quote">type1</span>&#8221;</span> or <span class="quote">&#8220;<span class="quote">x11</span>&#8221;</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="https://cdn.NetBSD.org/pub/pkgsrc/current/pkgsrc/fonts/dbz-ttf/README.html" target="_top"><code class="filename">fonts/dbz-ttf</code></a>:</p>

<p>One appealing feature of pkgsrc is that it runs on many

<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

    <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 (the lines in
    <code class="filename">Makefile</code> that are indented with a tab) this
    is no problem, since variables are only expanded when they are
    used. But in the preprocessor directives mentioned above and in
    dependency lines (of the form <code class="literal">target:

    time.</p>

<a name="user-interaction"></a>21.1.2. User interaction</h3></div></div></div>
<p>Occasionally, packages require interaction from the user,
    and this can be in a number of ways:</p>
<div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem"><p>When fetching the distfiles, some packages require user
	interaction such as entering username/password or accepting a
	license on a web page.</p></li>
<li class="listitem"><p>When extracting the distfiles, some packages may ask for
	passwords.</p></li>
<li class="listitem"><p>help to configure the package before it is built</p></li>
<li class="listitem"><p>help during the build process</p></li>
<li class="listitem"><p>help during the installation of a package</p></li>
</ul></div>
<p>A package can set the <code class="varname">INTERACTIVE_STAGE</code>
    variable to define which stages need interaction. This should be
    done in the package's <code class="filename">Makefile</code>, e.g.:</p>
<pre class="programlisting">
INTERACTIVE_STAGE=      configure install
</pre>
<p>The user can then decide to skip this package by setting the
    <code class="varname">BATCH</code> variable. Packages that require interaction
    are also excluded from bulk builds.</p>

<a name="handling-licenses"></a>21.1.3. Handling licenses</h3></div></div></div>
<p>Authors of software can choose the licence under which software
    can be copied.  The Free Software Foundation has declared some
    licenses "Free", and the Open Source Initiative has a definition of
    "Open Source".</p>
<p>By default, pkgsrc allows packages with Free or Open Source
    licenses to be built.  To allow packages with other licenses to be
    built as well, the pkgsrc user needs to add these licenses to the
    <code class="varname">ACCEPTABLE_LICENSES</code> variable in <a class="link" href="#mk.conf"><code class="filename">mk.conf</code></a>.  Note
    that this variable only affects which packages may be
    <span class="emphasis"><em>built</em></span>, while the license terms often also
    restrict the actual use of the package and its redistribution.</p>
<p>One might want to only install packages with a BSD license,
    or the GPL, and not the other.  The free licenses are added to the
    default <code class="varname">ACCEPTABLE_LICENSES</code> variable.  The pkgsrc
    user can override the default by setting the
    <code class="varname">ACCEPTABLE_LICENSES</code> variable with "=" instead
    of "+=".  The licenses accepted by default are defined in the
    <code class="varname">DEFAULT_ACCEPTABLE_LICENSES</code> variable in the file
    <code class="filename">pkgsrc/mk/license.mk</code>.</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.).
    Packages with redistribution restrictions should set these
    tags.</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="https://cdn.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>
===&gt; xv-3.10anb9 has an unacceptable license: xv-license.
===&gt;     To view the license, enter "/usr/bin/make show-license".
===&gt;     To indicate acceptance, add this line to your /etc/mk.conf:
===&gt;     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>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>

<p>When the license changes (in a way other than formatting),
    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 (FSF or OSI).</p>
</div>
</div>
<div class="sect2">
<div class="titlepage"><div><div><h3 class="title">
<a name="restricted-packages"></a>21.1.4. Restricted packages</h3></div></div></div>
<p>Some licenses restrict how software may be re-distributed.
    By declaring the restrictions, package tools can
    automatically refrain from e.g. placing binary packages on FTP
    sites.</p>
<p>There are four possible restrictions, 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.

    "FTP" means making the source or binary file available over the
    Internet at no charge.

    "CD-ROM" means making the source or binary available on some kind of
    media, together with other source and binary packages, 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 class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem">
<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 class="listitem">
<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">${RESTRICTED}</code>.</p>
</li>
<li class="listitem">
<p><code class="varname">NO_BIN_ON_FTP</code></p>
<p>Binaries may not made available on the Internet without
	charge.  In this case, set this variable to
	<code class="varname">${RESTRICTED}</code>.  If this variable is set,
	binary packages will not be included on ftp.NetBSD.org.</p>
</li>
<li class="listitem">
<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">${RESTRICTED}</code>.
	</p>
</li>
<li class="listitem">
<p><code class="varname">NO_SRC_ON_FTP</code></p>
<p>Distfiles may not made available via FTP at no charge.
	In this case, set this variable to
	<code class="varname">${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 packages will be removed from pkgsrc when the
    distfiles are not distributable and cannot be obtained for a period
    of one full quarter branch. Packages with manual/interactive fetch
    must have a maintainer and it is his/her responsibility to ensure
    this.</p>

<div class="sect2">
<div class="titlepage"><div><div><h3 class="title">
<a name="dependencies"></a>21.1.5. 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">DEPENDS</code>,
    <code class="varname">BUILD_DEPENDS</code>,
    <code class="varname">TOOL_DEPENDS</code>, and
    <code class="varname">TEST_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 18. Buildlink methodology">Chapter 18, <i>Buildlink methodology</i></a> for more information.</p>
<p>The basic difference is that 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>, <code class="varname">TOOL_DEPENDS</code>,
    and <code class="varname">TEST_DEPENDS</code> definitions do not, marking a
    dependency that is only needed for building or testing the resulting
    package. See also <a class="xref" href="#creating" title="Chapter 14. Creating a new pkgsrc package from scratch">Chapter 14, <i>Creating a new pkgsrc package from scratch</i></a> for more information.</p>
<p>This means that if you only need a package present whilst
    you are building or testing, it should be noted as a
    <code class="varname">TOOL_DEPENDS</code>,
    <code class="varname">BUILD_DEPENDS</code>, or
    <code class="varname">TEST_DEPENDS</code>.  When cross-compiling,
    <code class="varname">TOOL_DEPENDS</code> are <span class="emphasis"><em>native</em></span>
    packages, i.e. packages for the architecture where the package
    is built;
    <code class="varname">BUILD_DEPENDS</code> are <span class="emphasis"><em>target</em></span>
    packages, i.e., packages for the architecture for which the package
    is built.</p>
<p>The format for a <code class="varname">DEPENDS</code>,
    <code class="varname">BUILD_DEPENDS</code>, <code class="varname">TOOL_DEPENDS</code>,

<a name="not-building-packages"></a>21.1.7. Packages that cannot or should not be built</h3></div></div></div>
<p>There are several reasons why a package might be
    instructed to not build under certain circumstances.  If the
    package builds and runs on most platforms, the exceptions
    should be noted with <code class="varname">BROKEN_ON_PLATFORM</code>.  If
    the package builds and runs on a small handful of platforms,
    set <code class="varname">BROKEN_EXCEPT_ON_PLATFORM</code> instead.
    Both <code class="varname">BROKEN_ON_PLATFORM</code> and
    <code class="varname">BROKEN_EXCEPT_ON_PLATFORM</code> are OS triples
    (OS-version-platform) that can use glob-style
    wildcards.</p>
<p>If a package is not appropriate for some platforms (as
    opposed to merely broken), a different set of variables should be
    used as this affects failure reporting and statistics.
    If the package is appropriate for most platforms, the exceptions
    should be noted with <code class="varname">NOT_FOR_PLATFORM</code>.  If
    the package is appropriate for only a small handful of platforms
    (often exactly one), 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
    (OS-version-platform) that can use glob-style
    wildcards.</p>
<p>Some packages are tightly bound to a specific version of an
    operating system, e.g. LKMs or <a href="https://cdn.NetBSD.org/pub/pkgsrc/current/pkgsrc/sysutils/lsof/README.html" target="_top"><code class="filename">sysutils/lsof</code></a>.  Such binary packages are not
    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">&#8220;<span class="quote">yes</span>&#8221;</span>.  This variable is not currently used by any of
    the package system internals, but may be used in the
    future.</p>
<p>If the package should be skipped (for example, because it
    provides functionality already provided by the system), set
    <code class="varname">PKG_SKIP_REASON</code> to a descriptive message.  If
    the package should fail because some preconditions are not met,
    set <code class="varname">PKG_FAIL_REASON</code> to a descriptive
    message.</p>

    on package versions by setting <code class="varname">PKGREVISION=1</code>
    (2, ...). The <span class="quote">&#8220;<span class="quote">nb</span>&#8221;</span> is treated like a
    <span class="quote">&#8220;<span class="quote">.</span>&#8221;</span> by the package tools. e.g.</p>
<pre class="programlisting">
DISTNAME=       foo-17.42

</pre>
<p>will result in a <code class="varname">PKGNAME</code> of
    <span class="quote">&#8220;<span class="quote">foo-17.42nb9</span>&#8221;</span>. If you want to use the original
    value of <code class="varname">PKGNAME</code> without the <span class="quote">&#8220;<span class="quote">nbX</span>&#8221;</span>

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

<a name="fixes.subst"></a>21.1.11. 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
multiple times in the same file, it is cumbersome to maintain a patch
file for this. This is where the SUBST framework steps in. It provides an
easy-to-use interface for replacing text in files. It just needs the
following information:</p>
<div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem"><p>In which phase of the package build cycle should the
replacement happen?</p></li>
<li class="listitem"><p>In which files should the replacement
happen?</p></li>
<li class="listitem"><p>Which text should be replaced with
what?</p></li>
</ul></div>
<p>This information is encoded in a block of <code class="varname">SUBST</code>
variables. A minimal example is:</p>
<pre class="programlisting">
SUBST_CLASSES+=         paths
SUBST_STAGE.paths=      pre-configure
SUBST_FILES.paths=      src/*.c
SUBST_SED.paths=        -e 's,/usr/local,${PREFIX},g'
</pre>
<p>Translated into English, it means: In the pre-configure stage (that
is, after applying the patches from the patches/ directory and before
running the configure script and the portability check), replace the text
<code class="literal">/usr/local</code> with the content of the variable
<code class="varname">PREFIX</code>.</p>
<p>Each SUBST block starts by appending an identifier to
<code class="varname">SUBST_CLASSES</code> (note the <code class="literal">+=</code>). This
identifier can be chosen freely by the package. If there should ever be
duplicate identifiers, the pkgsrc infrastructure will catch this and fail
early, so don't worry about name collisions.</p>
<p>Except for <code class="varname">SUBST_CLASSES</code>, all variables in a
SUBST block are parameterized using this identifier. In the remainder of
this section, these parameterized variables are written as
<code class="varname">SUBST_STAGE.*</code>.</p>
<pre class="programlisting">
SUBST_CLASSES+=         paths
SUBST_STAGE.paths=      pre-configure
SUBST_MESSAGE.paths=    Fixing absolute paths.
SUBST_FILES.paths=      src/*.c
SUBST_FILES.paths+=     scripts/*.sh
SUBST_SED.paths=        -e 's,"/usr/local,"${PREFIX},g'
SUBST_SED.paths+=       -e 's,"/var/log,"${VARBASE}/log,g'
SUBST_VARS.paths=       LOCALBASE PREFIX PKGVERSION
</pre>
<p>To get a complete picture about the SUBST substitutions, run
<span class="command"><strong>bmake show-all-subst</strong></span>. If something doesn't work as
expected, run pkglint on the package, which detects several typical
mistakes surrounding the SUBST blocks. For any questions that might
remain after this, have a look at
<code class="filename">mk/subst.mk</code>.</p>

<div class="titlepage"><div><div><h4 class="title">
<a name="fixes.subst.when"></a>21.1.11.1. Choosing the time where the substitutions happen</h4></div></div></div>
<p>The <code class="varname">SUBST_STAGE.*</code> is one of
{pre,do,post}-{extract,patch,configure,build,test,install}. Of these,
<code class="literal">pre-configure</code> is used most often, by far. The most
popular stages are, in chronological order:</p>
<div class="variablelist"><dl class="variablelist">
<dt><span class="term"><code class="literal">post-extract</code></span></dt>
<dd>
<p>The substitutions are applied immediately after the
distfiles are extracted. Running <span class="command"><strong>bmake extract</strong></span> on the
package will leave no traces of the original files.</p>
<p>When the substitution applies to files for which there is also a
patch in the <code class="filename">patches/</code> directory, this means that the
patches will be computed based on the result of the substitution. When
these patches are sent to the upstream maintainer later, to be fixed in
the upstream package, these patches may no longer match what the upstream
author is used to. Because of this, <code class="literal">pre-configure</code> is
often a better choice.</p>
</dd>
<dt><span class="term"><code class="literal">pre-configure</code></span></dt>
<dd>
<p>The substitutions are applied after the patches from the
<code class="filename">patches/</code> directory. This makes it possible to run
<span class="command"><strong>bmake patch</strong></span> on the package, after which the patches
can be edited using the tools pkgvi and mkpatches from the <a href="https://cdn.NetBSD.org/pub/pkgsrc/current/pkgsrc/pkgtools/pkgdiff/README.html" target="_top"><code class="filename">pkgtools/pkgdiff</code></a> package.</p>
<p>When updating the patches, it is helpful to explicitly separate the
<span class="command"><strong>bmake patch</strong></span> from the <span class="command"><strong>bmake
configure</strong></span>, and to only edit the patches between these commands.
Otherwise the substitutions from the SUBST block will end up in the patch
file. When this happens in really obvious ways, pkglint will complain
about patches that contain a hard-coded <code class="literal">/usr/pkg</code>
instead of the correct and intended <code class="literal">@PREFIX@</code>, but it
can only detect these really obvious
cases.</p>
</dd>
<dt><span class="term"><code class="literal">do-configure</code></span></dt>
<dd><p>This stage should only be used if the package defines a
<code class="literal">pre-configure</code> action itself, and the substitution must
happen after that. Typical examples are packages that use the
<code class="literal">pre-configure</code> stage to regenerate the GNU configure
script from
<code class="filename">configure.ac</code>.</p></dd>
<dt><span class="term"><code class="literal">post-configure</code></span></dt>
<dd><p>This stage is used to fix up any mistakes by the
configure stage.</p></dd>
<dt><span class="term"><code class="literal">pre-build</code></span></dt>
<dd><p>This stage should only be used for substitutions that are
clearly related to building the package, not for fixing the
configuration. Substitutions for pathnames (such as replacing
<code class="filename">/usr/local</code> with <code class="literal">${PREFIX}</code>) or
user names (such as replacing <code class="literal">@MY_USER@</code> with the
actual username) belong in pre-configure or post-configure
instead.</p></dd>
<dt><span class="term"><code class="literal">post-build</code></span></dt>
<dd>
<p>Just as with pre-build, this stage should only be used
for substitutions that are clearly related to building the package, not
for fixing the configuration. Substitutions for pathnames (such as
replacing <code class="filename">/usr/local</code> with
<code class="literal">${PREFIX}</code>) or user names (such as replacing
<code class="literal">@MY_USER@</code> with the actual username) belong in
pre-configure or post-configure instead.</p>
<p>A typical use is to update pkg-config files to include the rpath
compiler options.</p>
</dd>
<dt><span class="term"><code class="literal">pre-install</code></span></dt>
<dd><p>In general, the install phase should be as simple as
possible. As with the pre-build and post-build stages, it should not be
used to fix pathnames or user names, these belong in pre-configure
instead. There are only few legitimate use cases for applying
substitutions in this stage.</p></dd>

<div class="titlepage"><div><div><h4 class="title">
<a name="fixes.subst.where"></a>21.1.11.2. Choosing the files where the substitutions happen</h4></div></div></div>
<p>The <code class="varname">SUBST_FILES.*</code> variable contains a list of
filename patterns. These patterns are relative to
<code class="varname">WRKSRC</code> since that is where most substitutions happen.
A typical example is:</p>
<pre class="programlisting">
SUBST_FILES.path=       Makefile */Makefile */*/Makefile *.[ch]
</pre>
<p>The above patterns, especially the last, are quite broad. The SUBST
implementation checks that each filename pattern that is mentioned here
has an effect. For example, if none of the
<code class="filename">*/*/Makefile</code> files contains the patterns to be found
and substituted, that filename pattern is redundant and should be left
out. By default, the SUBST framework will complain with an error message.
If the text to be substituted occurs in some of the files from a single
pattern, but not in all of them, that is totally ok, and the SUBST
framework will only print an INFO message for those files.</p>
<p>If there is a good reason for having redundant filename patterns,
set <code class="varname">SUBST_NOOP_OK.*</code> to <code class="literal">yes</code>.</p>
<p>Another popular way of choosing the files for the substitutions is
via a shell command, like this:</p>
<pre class="programlisting">
C_FILES_CMD=            cd ${WRKSRC} &amp;&amp; ${FIND} . -name '*.c'
SUBST_FILES.path=       ${C_FILES_CMD:sh}
</pre>
<p>The variable name <code class="varname">C_FILES_CMD</code> in this example is
freely chosen and independent of the SUBST framework.</p>
<p>In this variant, the <code class="varname">SUBST_FILES.*</code> variable
lists each file individually. Thereby chances are higher that there are
filename patterns in which no substitution happens. Since the SUBST
framework cannot know whether the filename patterns in
<code class="varname">SUBST_FILES.*</code> have been explicitly listed in the
Makefile (where any redundant filename pattern would be suspicious) or
been generated by a shell command (in which redundant filename patterns
are more likely and to be expected), it will complain about these
redundant filename patterns. Therefore, SUBST blocks that use a shell
command to generate the list of filename patterns often need to set
<code class="varname">SUBST_NOOP_OK.*</code> to <code class="literal">yes</code>.</p>
</div>
<div class="sect3">
<div class="titlepage"><div><div><h4 class="title">
<a name="fixes.subst.what"></a>21.1.11.3. Choosing what to substitute</h4></div></div></div>
<p>In most cases, the substitutions are given using one or more
<a class="citerefentry" href="https://man.NetBSD.org/NetBSD-9.1/i386/sed.1"><span class="citerefentry"><span class="refentrytitle">sed</span>(1)</span></a> commands, like this:</p>
<pre class="programlisting">
SUBST_SED.path=         -e 's|/usr/local|${PREFIX}|g'
</pre>
<p>Each of the sed commands needs to be preceded by the
<code class="literal">-e</code> option and should be specified on a line of its
own, to avoid hiding short sed commands at the end of a line.</p>
<p>Since the sed commands often contain shell metacharacters as the
separator (the <code class="literal">|</code> in the above example), it is common
to enclose them in single quotes.</p>
<p>A common substitution is to replace placeholders of the form
<code class="literal">@VARNAME@</code> with their pkgsrc counterpart variable
<code class="literal">${VARNAME}</code>. A typical example is:</p>
<pre class="programlisting">
SUBST_VARS.path=        PREFIX
</pre>
<p>This type of substitutions is typically done by the GNU configure
scripts during the do-configure stage, but in some cases these need to be
overridden. The same pattern is also used when a package defines patches
that replace previously hard-coded paths like
<code class="literal">/usr/local</code> with a <code class="literal">@PREFIX@</code>
placeholder first, which then gets substituted by the actual
<code class="literal">${PREFIX}</code> in the pre-configure stage. In many of these
cases, it works equally well to just use the SUBST framework to directly
replace <code class="literal">/usr/local</code> with <code class="literal">${PREFIX}</code>,
thereby omitting the intermediate patch file.</p>
<p>If the above is not flexible enough, it is possible to not use sed
at all for the substitution but to specify an entirely different command,
like this:</p>
<pre class="programlisting">
SUBST_FILTER_CMD.path=  LC_ALL=C ${TR} -d '\r'
</pre>
<p>This is used for the few remaining packages in which the
distributed files use Windows-style line endings that need to be
converted to UNIX-style line endings.</p>

overridden by setting <code class="literal">SUBST_MESSAGE.*</code> to an individual
message.</p>

    example of this usage.</p>
<p>If the download can't be automated, because the user must
    submit personal information to apply for a password, or must pay
    for the source, or whatever, you can set

<a name="modified-distfiles-same-name"></a>21.2.2. 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.</p>
<p>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> (but take care with
    python or ruby packages, where <code class="varname">PKGNAME</code> includes
    a variable prefix). 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="21.1.10. How to handle incrementing versions when fixing an existing package">Section 21.1.10, &#8220;How to handle incrementing versions when fixing an existing package&#8221;</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>.</p>
<p><code class="varname">DIST_SUBDIR</code> is also used when a distfile's
    name does not contain a version and the distfile is apt to change. In
    cases where the likelihood of this is very small,
    <code class="varname">DIST_SUBDIR</code> might not be required. Additionally,
    <code class="varname">DIST_SUBDIR</code> must not be removed unless the
    distfile name changes, even if a package is being moved or
    renamed.</p>
<p>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>

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.

<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>

<p>Some source files trigger bugs in the compiler, based on

	<code class="varname">MACHINE_ARCH</code> and compiler.</p>
<p>This used to be a big problem in the past, but is rarely
	needed now as compiler technology has matured. If you still need
	to add a compiler specific workaround, please do so in the file
	<code class="filename">hacks.mk</code> and describe the symptom and

<a name="fixes.build.header"></a>21.5.3. No such file or directory</h3></div></div></div>
<p>Compilation sometimes fails with an error message like this:</p>
<pre class="programlisting">
.../x11/gtk3/work/gtk+-3.24.12/gdk/gdktypes.h:35:10:
    fatal error: pango/pango.h: No such file or directory
</pre>
<p>The proper way to fix this problem depends on the type of the
header, which is described in the following sections.</p>
<div class="sect3">
<div class="titlepage"><div><div><h4 class="title">
<a name="fixes.build.header.bl3"></a>21.5.3.1. Headers from other packages</h4></div></div></div>
<p>If the header name looks like it comes from a different package,
that other package should be included via the buildlink3
framework.</p>
<p>First, look whether the header is somewhere in the buildlink3
directory below <code class="varname">WRKDIR</code>. In the above case of
the missing Pango header:</p>
<pre class="programlisting">
<code class="prompt">$</code> find work/.buildlink/ -print | grep -F pango/pango.h
</pre>
<p>In the case of Pango, the output is:</p>
<pre class="programlisting">
work/.buildlink/include/pango-1.0/pango/pango.h
</pre>
<p>If the <code class="filename">pango/pango.h</code> file were placed directly
in the <code class="filename">.buildlink</code> directory, it would have been
found automatically. There is an extra <code class="filename">pango-1.0</code>
path component though, which means that the compiler command line must
contain an option of the form
<code class="literal">-I${BUILDLINK3_PREFIX.pango}/include/pango-1.0</code>. In
most cases this option is generated by the configure script, which can be examined using:</p>
<pre class="programlisting">
<code class="prompt">$</code> $ grep -o '[-]I[^[:space:]]*/pango[^[:space:]]*' work/*/Makefile
-I/usr/pkg/include/pango-1.0
-I/usr/pkg/include/pango-1.0
-I/usr/pkg/include/pango-1.0
-I/usr/pkg/include/pango-1.0
-I/usr/pkg/include/pango-1.0
</pre>
<p>This looks good. These options are transformed by the buildlink
wrapper to refer to the correct path inside
<code class="filename">work/.buildlink</code>.</p>
<p>Since the compilation fails though, examine the compiler command
lines in <code class="filename">work/.work.log</code> to see whether the
<code class="literal">-I</code> option is included in the particular command
line.</p>
<p>To further analyze the situation, run <span class="command"><strong>bmake
build-env</strong></span>, which sets up an interactive, realistic environment
including all the pkgsrc wrapper commands and environment variables. From
there, try to compile some simple example programs that use the
header.</p>

<p>If the name of the header seems to come from the package itself,
and if the build is run with parallel jobs, the package may have some
undeclared dependencies between the <code class="filename">.c</code> and the
<code class="filename">.h</code> files, and a C file is compiled before its
required header is generated.</p>
<p>To see whether the build runs with parallel jobs, run

like this:</p>

<p>When building a hierarchy of packages, it may happen that one

various hard to diagnose build errors. To clean up the situation:</p>
<pre class="programlisting">
<code class="prompt">$</code> (cd ../../ &amp;&amp; test -f mk/bsd.pkg.mk &amp;&amp; rm -rf */*/work)

<p>(The test for <code class="filename">bsd.pkg.mk</code> just prevents running

<p>On platforms other than BSD, third-party packages are installed in
<code class="filename">/usr/include</code>, together with the base system. This
means that pkgsrc cannot distinguish between headers provided by the base
system (which it needs) and headers from third-party packages (which are
often included in pkgsrc as well). This can lead to subtle version
mismatches.</p>
<p>In pkgsrc installations that have been active for several years, it
may happen that some files are manually deleted. To exclude this unlikely
reason, run <span class="command"><strong>pkg_admin check</strong></span>.</p>

<p>Sometimes packages fail to build because the compiler runs

<p>An exception to the above is that library API documentation

<p>An example that illustrates some of the variables described above is

    file. The <span class="quote">&#8220;<span class="quote">install-info</span>&#8221;</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

    <span class="quote">&#8220;<span class="quote">info</span>&#8221;</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">&#8220;<span class="quote">makeinfo</span>&#8221;</span> command
    at build time must add <span class="quote">&#8220;<span class="quote">makeinfo</span>&#8221;</span> to
    <code class="varname">USE_TOOLS</code> in its Makefile. If a minimum
    version of the <span class="quote">&#8220;<span class="quote">makeinfo</span>&#8221;</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="https://cdn.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

<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

  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="https://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="https://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>

<li class="listitem">
<p>Almost all GNOME applications use the GNU Autotools as their

<li class="listitem">
<p>If the package uses gtk-doc (a documentation generation

<p>The default location of installed HTML files
    (<code class="filename">share/gtk-doc/&lt;package-name&gt;</code>) is correct

<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

<a name="full-update"></a>22.3. 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 class="variablelist">
<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 class="orderedlist" type="1">
<li class="listitem">
<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' 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 }' &gt;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 }' &gt;&gt;list.txt</code></strong></pre>
</li>
<li class="listitem"><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 class="listitem">
<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="https://cdn.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 class="listitem">
<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' &gt;todo.txt</code></strong></pre>
</li>
<li class="listitem"><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 class="listitem"><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 class="listitem"><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-&lt;YEAR&gt;</code> and
    <a href="http://cvsweb.NetBSD.org/bsdweb.cgi/pkgsrc/doc/TODO?rev=HEAD&amp;content-type=text/x-cvsweb-markup" target="_top"><code class="filename">pkgsrc/doc/TODO</code></a> files.</p></li>

<a name="patching"></a>22.4. 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="12.3.5. Feedback to the author">Section 12.3.5, &#8220;Feedback to the author&#8221;</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="https://bugzilla.gnome.org/" target="_top">GNOME's Bugzilla</a> and the <a class="ulink" href="https://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="12.3.4. Patching guidelines">Section 12.3.4, &#8220;Patching guidelines&#8221;</a>) for more
details.</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" title="Chapter 8. Creating binary packages for everything in pkgsrc (bulk builds)">Chapter 8, <i>Creating binary packages for everything in pkgsrc (bulk

<a name="submitting-your-package"></a>23.2. 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="#creating" title="Chapter 14. Creating a new pkgsrc package from scratch">Chapter 14, <i>Creating a new pkgsrc package from scratch</i></a> and the rest of this
	document. Next, generate an uuencoded gzipped <a class="citerefentry" href="https://man.NetBSD.org/NetBSD-9.1/i386/tar.1"><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="https://man.NetBSD.org/NetBSD-9.1/i386/send-pr.1"><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="https://www.NetBSD.org/support/send-pr.html" target="_top">https://www.NetBSD.org/support/send-pr.html</a>,
	which contains some instructions and a link to a form where you
	can submit packages.  The
	<a href="https://cdn.NetBSD.org/pub/pkgsrc/current/pkgsrc/sysutils/gtk-send-pr/README.html" target="_top"><code class="filename">sysutils/gtk-send-pr</code></a> package is
	also available as a substitute for either of the above two tools.
	</p>
<p>In the form of the problem report, the category should be
	<span class="quote">&#8220;<span class="quote">pkg</span>&#8221;</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">&#8220;<span class="quote">fix</span>&#8221;</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">&#8220;<span class="quote">pkgsrc work-in-progress</span>&#8221;</span>); see the

<a name="general-notes-for-changes"></a>23.3. 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="https://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. The target also automatically
  removes possibly existing entries for the package in the
  <code class="filename">TODO</code> file. Don't forget to commit
  the changes, e.g. by using <span class="command"><strong>make commit-changes-entry</strong></span>!
  If you are not using a checkout directly from cvs.NetBSD.org, but e.g.
  a local copy of the repository, you can set USE_NETBSD_REPO=yes. This
  makes the cvs commands use the main repository.

<a name="commit-messages"></a>23.4. Commit Messages</h2></div></div></div>
<p>For several years, there have been mirrors of pkgsrc in
  fossil, git, and hg. Standard practise when using these tools is to
  make the first line of a commit message function as a summary that
  can be read without the rest, such as is commonly done with "git log
  --oneline". For this reason, we have the following guidelines for
  pkgsrc commit messages:</p>
<div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem"><p>Start the commit message with a line that explains the
    big picture in 65 characters or less. When a commit is for one
    package, include the name of the package. For updates, include the
    version to which it is updated.</p></li>
<li class="listitem"><p>Leave the next line empty.</p></li>
<li class="listitem"><p>Then come the details for the commit (changes in that
    package, reason for a change) and any relevant PRs. Wrap this
    section.</p></li>
</ul></div>
<p>Here is an example:
  </p>
<pre class="programlisting">
  libxslt: update to 1.0.30

  Changes since 1.0.29:
  ...
  </pre>
<p>
  </p>
<p>Here is another example:
  </p>
<pre class="programlisting">
  mk/bsd.pkg.mk: enable SSP by default on NetBSD

  (rationale)
  </pre>
<p>
  </p>
<p>Commit messages are final: no <span class="quote">&#8220;<span class="quote">cvs admin</span>&#8221;</span> is
  allowed on the pkgsrc repository to change commit messages.</p>

<p>This section is only of interest for pkgsrc developers with write
  access to the pkgsrc repository.</p>
<p>When the package is finished, <span class="quote">&#8220;<span class="quote">cvs add</span>&#8221;</span> the files.
Start by adding the directory and then files in the directory. Don't
forget to add the new package to the category's
<code class="filename">Makefile</code>. Make sure you don't forget any files;
you can check by running <span class="quote">&#8220;<span class="quote">cvs status</span>&#8221;</span>. An example:</p>
<pre class="programlisting">
<code class="prompt">$</code> cd .../pkgsrc/category
<code class="prompt">$</code> cvs add pkgname
<code class="prompt">$</code> cd pkgname
<code class="prompt">$</code> cvs add DESCR Makefile PLIST distinfo buildlink3.mk patches
<code class="prompt">$</code> cvs add patches/p*
<code class="prompt">$</code> cvs status | less
<code class="prompt">$</code> cvs commit
<code class="prompt">$</code> cd ..
<code class="prompt">$</code> vi Makefile # add SUBDIRS+=pkgname line
<code class="prompt">$</code> cvs commit Makefile
<code class="prompt">$</code> cd pkgname
<code class="prompt">$</code> make CTYPE=Added commit-changes-entry
</pre>
<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>Also mention the new package in
<code class="filename">pkgsrc/doc/CHANGES-20xx</code>.</p>
<p>Previously, <span class="quote">&#8220;<span class="quote">cvs import</span>&#8221;</span> was suggested, but it was
much easier to get wrong than <span class="quote">&#8220;<span class="quote">cvs add</span>&#8221;</span>.</p>

<a name="updating-package"></a>23.6. 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 class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem"><p>A URL is volatile, and can change over time. It may go away completely

<li class="listitem"><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>When renaming packages, be sure to fix any references to the old name

<p>
  Also, when renaming a package, please add
  the package name and version pattern(s) of the previous package

  This may be repeated for multiple renames.
  The new package would be an exact replacement.

<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>
<div class="sect1">
<div class="titlepage"><div><div><h2 class="title" style="clear: both">
<a name="infr.vardef"></a>25.1. 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">&#8220;<span class="quote">yes</span>&#8221;</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>
</div>
<div class="sect1">
<div class="titlepage"><div><div><h2 class="title" style="clear: both">
<a name="infr.vardef.problems"></a>25.2. 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">&#8220;<span class="quote">know</span>&#8221;</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">&#8220;<span class="quote"><code class="literal">c</code></span>&#8221;</span>) is so short that it
	doesn't stand out. Nevertheless it is mentioned in many
	files.</p>
</div>
<div class="sect1">

<a name="infr.var"></a>25.3. Variable evaluation</h2></div></div></div>
<div class="sect2">
<div class="titlepage"><div><div><h3 class="title">
<a name="infr.var.load"></a>25.3.1. 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 class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem"><p>The right hand side of the <code class="literal">:=</code>
	and <code class="literal">!=</code> operators,</p></li>
<li class="listitem"><p>Make directives like <code class="literal">.if</code> or
	<code class="literal">.for</code>,</p></li>
<li class="listitem"><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>

<div class="sect2">
<div class="titlepage"><div><div><h3 class="title">
<a name="infr.var.run"></a>25.3.2. At runtime</h3></div></div></div>
<p>After all the files have been loaded, the values of the
	variables cannot be changed anymore. Variables that are used in
	the shell commands are expanded at this point.</p>

<a name="infr.varspec"></a>25.4. How can variables be specified?</h2></div></div></div>
<p>There are many ways in which the definition and use of a
	variable can be restricted in order to detect bugs and violations
	of the (mostly unwritten) policies. A package can be checked with
	<code class="literal">pkglint -Wall</code> to see whether it meets these
	rules.</p>

<p>Most of the <code class="filename">.mk</code> files fall into one

<p>In a traditional imperative programming language some of

	procedures. They take some input parameters and&mdash;after

	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 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>

<p>Action files take some input parameters and may define

	There are action files that are included implicitly by the
	pkgsrc infrastructure, while other must be included

<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">
<div class="titlepage"><div><div><h3 class="title">
<a name="infr.order.prefs"></a>25.6.1. The order in <code class="filename">bsd.prefs.mk</code>

<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">

<a name="infr.order.pkg"></a>25.6.2. 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 class="sect1">
<div class="titlepage"><div><div><h2 class="title" style="clear: both">
<a name="regression.run"></a>26.1. Running the regression tests</h2></div></div></div>
<p>You first need to install the <a href="https://cdn.NetBSD.org/pub/pkgsrc/current/pkgsrc/pkgtools/pkg_regress/README.html" target="_top"><code class="filename">pkgtools/pkg_regress</code></a> package, which
	provides the <span class="command"><strong>pkg_regress</strong></span> command. Then you
	can simply run that command, which will run all tests in the
	<code class="filename">regress/</code> directory.</p>

<div class="sect1">
<div class="titlepage"><div><div><h2 class="title" style="clear: both">
<a name="regression.new"></a>26.2. Adding a new regression test</h2></div></div></div>
<p>Every directory in the <code class="filename">regress/</code>
	directory that contains a file called <code class="filename">spec</code>
	is considered a regression test. This file is a shell program
	that is included by the <span class="command"><strong>pkg_regress</strong></span> command.
	The following functions can be overridden to suit your
	needs.</p>
<div class="sect2">
<div class="titlepage"><div><div><h3 class="title">
<a name="regression.fun.override"></a>26.2.1. Overridable functions</h3></div></div></div>
<p>These functions do not take any parameters. Although they
	are called in <span class="quote">&#8220;<span class="quote">set -e</span>&#8221;</span> mode, they don't stop at the
	first failing command. See <a class="ulink" href="https://stackoverflow.com/q/4072984" target="_top">this Stack Overflow

<dd><p>This function prepares the environment for the
	test. By default it does nothing.</p></dd>
<dt><span class="term"><code class="varname">do_test</code></span></dt>
<dd>
<p>This function runs the actual test. By default,
	it calls <code class="varname">TEST_MAKE</code> with the arguments
	<code class="varname">MAKEARGS_TEST</code> and writes its output including
	error messages into the file
	<code class="varname">TEST_OUTFILE</code>.</p>
<p>When defining this function, make sure that all output that
	needs to be checked is written to the correct output file.
	Example:</p>
<pre class="programlisting">
do_test() {
        echo "Example output"
} 1&gt;$TEST_OUTFILE 2&gt;&amp;1
</pre>
</dd>
<dt><span class="term"><code class="varname">check_result</code></span></dt>
<dd>
<p>This function is run after the test and is
	typically used to compare the actual output from the one that is
	expected. It can make use of the various helper functions from
	the next section. Example:</p>
<pre class="programlisting">

        exit_status 0
        output_require "Example"

</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">
<div class="titlepage"><div><div><h2 class="title" style="clear: both">
<a name="porting.opsys"></a>27.1. 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 class="variablelist">
<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>

	example the name of the C
	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/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="https://cdn.NetBSD.org/pub/pkgsrc/current/pkgsrc/lang/perl5/README.html" target="_top"><code class="filename">lang/perl5</code></a>, <a href="https://cdn.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">
<div class="titlepage"><div><div><h2 class="title" style="clear: both">
<a name="ftp-distfiles"></a>C.1. <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">
<div class="titlepage"><div><div><h2 class="title" style="clear: both">
<a name="ftp-misc"></a>C.2. <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">
<div class="titlepage"><div><div><h2 class="title" style="clear: both">
<a name="ftp-packages"></a>C.3. <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 class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem"><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 class="listitem"><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 class="listitem"><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 class="listitem"><p><code class="varname">TAG</code> is either
	<code class="literal">20<em class="replaceable"><code>xx</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">
<div class="titlepage"><div><div><h2 class="title" style="clear: both">
<a name="ftp-reports"></a>C.4. <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.3. packages: Binary packages">Section C.3, &#8220;<code class="filename">packages</code>: Binary packages&#8221;</a>.</p>
</div>
<div class="sect1">
<div class="titlepage"><div><div><h2 class="title" style="clear: both">
<a name="ftp-source"></a>C.5. <code class="filename">current</code>,
<code class="filename">stable</code>,
<code class="filename">pkgsrc-20<em class="replaceable"><code>xx</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">&#8220;<span class="quote">real</span>&#8221;</span> pkgsrc,
	that is the files that define how to create binary packages from
	source archives.</p>
<p>Each of the <code class="filename">current</code>,
	<code class="filename">stable</code> and
	<code class="filename">pkgsrc-20<em class="replaceable"><code>xx</code></em>Q<em class="replaceable"><code>y</code></em></code>
	directories share the same structure.  They each contain a
	<code class="filename">pkgsrc</code> directory and
	<code class="filename">pkgsrc.tar.{bz,gz,xz}</code> file.</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.{bz,gz,xz}</code> contains the same
	as the directory, ready to be downloaded as a whole.</p>
<p>The <code class="filename">current</code> directory contains files
	related to the HEAD branch of the CVS repository.
	In this directory there is an additional file called
	<code class="filename">pkgsrc-readmes.tar.{bz,gz,xz}</code> that contains
	all pkgsrc <code class="filename">README</code>s with information about
	categories and packages.
	</p>
<p>The <code class="filename">stable</code> directory is a symlink to
	the latest 
	<code class="filename">pkgsrc-20<em class="replaceable"><code>xx</code></em>Q<em class="replaceable"><code>y</code></em></code>.
	</p>
<p>The
	<code class="filename">pkgsrc-20<em class="replaceable"><code>xx</code></em>Q<em class="replaceable"><code>y</code></em></code>.
	directories contain files related to the 
	<code class="filename">-20<em class="replaceable"><code>xx</code></em>Q<em class="replaceable"><code>y</code></em></code>
	stable branch of the CVS repository. In these directories there is
	an additional file called
	<code class="filename">pkgsrc-20<em class="replaceable"><code>xx</code></em>Q<em class="replaceable"><code>y</code></em>.tar.{bz,gz,xz}</code>,
	which contains the state of pkgsrc when it was branched.</p>

<a name="procedure"></a>E.2. Procedure</h2></div></div></div>
<p>The procedure to edit the pkgsrc guide is:</p>
<div class="procedure"><ol class="procedure" type="1">
<li class="step"><p>Make sure you have checked out the htdocs repository
	into a sibling directory of your pkgsrc directory.  You will need
	the ability to commit from both pkgsrc and htdocs.</p></li>
<li class="step"><p>Make sure you have the packages needed to
	regenerate the pkgsrc guide (and other XML-based NetBSD
	documentation) installed. These are automatically installed when
	you install the <a href="https://cdn.NetBSD.org/pub/pkgsrc/current/pkgsrc/meta-pkgs/pkgsrc-guide-tools/README.html" target="_top"><code class="filename">meta-pkgs/pkgsrc-guide-tools</code></a> package.</p></li>
<li class="step"><p>Run <span class="command"><strong>cd doc/guide</strong></span> to get to the
	right directory. All further steps will take place
	here.</p></li>
<li class="step"><p>Edit the XML file(s) in
	<code class="filename">files/</code>.</p></li>
<li class="step"><p>Run <span class="command"><strong>bmake</strong></span> to check the pkgsrc
	guide for valid XML and to build the final output files. If you
	get any errors at this stage, you can just edit the files, as
	there are only symbolic links in the working directory, pointing
	to the files in <code class="filename">files/</code>.</p></li>
<li class="step"><p><span class="command"><strong>(cd files &amp;&amp; cvs
	commit)</strong></span></p></li>
<li class="step"><p>Run <span class="command"><strong>bmake clean &amp;&amp; bmake</strong></span> to
	regenerate the output files with the proper RCS
	Ids.</p></li>
<li class="step">
<p>Run <span class="command"><strong>bmake regen</strong></span> to install and
	commit the files in both <code class="filename">pkgsrc/doc</code> and
	<code class="filename">htdocs</code>.</p>
<div class="note" style="margin-left: 0.5in; margin-right: 0.5in;">
<h3 class="title">Note</h3>
<p>If you have added, removed or renamed some chapters,
	you need to synchronize them using <span class="command"><strong>cvs add</strong></span> or
	<span class="command"><strong>cvs delete</strong></span> in the htdocs
	directory.</p>
