 0 Intro
 =======

There is a lot of software freely available for Unix based systems, which
usually runs on NetBSD, too, sometimes with some modifications. The NetBSD
packages collection incorporates any such changes necessary to make that
software run on NetBSD, and makes the installation (and reinstallation) of
the software package easy by means of a single command.

The NetBSD package system is used to enable such freely available
third-party software to be built easily on NetBSD hosts. Once the software
has been built, it is manipulated with the pkg_* tools so that installation
and de-installation, printing of an inventory of all installed packages and
retrieval of one-line comments or more verbose descriptions are all simple.

Both the NetBSD packages collection and the NetBSD package system are
derived from FreeBSD.


 0.1 Overview
 ============

This document is divided into two parts.  The first, "User's Guide",
describes how one can use one of the packages in the Package
Collection, either by installing a precompiled binary package, or
by building your own copy using the NetBSD package system.  The
second part, "Package Constructor's Guide", explains how to prepare
a package so it can be easily built by other NetBSD users without
knowing about the package's building details.


 0.2 Terminology
 ===============

There has been a lot of talk about "ports", "packages", etc. so far. Here
is a description of all the terminology used within this document:

 * Package:
   A set of files and building instructions that describe what's necessary
   to build a certain piece of software using the NetBSD package
   system. Packages are traditionally stored under /usr/pkgsrc.

 * The NetBSD package system:
   This is the part of the NetBSD operating system handling building
   (compiling), installing, and removing of packages.

 * Distfile:
   This term describes the file or files that are provided by the author
   of the piece of freely available software to distribute his work. All
   the changes necessary to build on NetBSD are reflected in the
   corresponding package. Usually the distfile is in the form of a
   compressed tar-archive, but other types are possible, too. Distfiles
   are stored below /usr/pkgsrc/distfiles.

 * Port:
   This is the term used by FreeBSD people for what we call a package.
   In NetBSD terminology, "port" refers to a different architecture.

 * Precompiled (binary) package:
   A set of binaries built by the NetBSD package system from a distfile
   using the NetBSD package system and stuffed together in a single .tgz
   file so it can be installed on machines of the same machine architecture
   without the need to recompile. Packages are generated in
   /usr/pkgsrc/packages by the NetBSD package system; there is also an
   archive on ftp.netbsd.org.

   Sometimes, this is referred to by the term "package" too,
   especially in the context of precompiled packages.

 * Program:
   The piece of software to be installed which will be constructed from
   all the files in the Distfile by the actions defined in the
   corresponding package. 

 * NetBSD RCS IDs:
   Some files in a package contain RCS IDs to reflect which version of
   that file this is (inserted automatically by cvs). These IDs are used
   in several examples within this document, but as this document itself
   is managed by CVS, it can't list the RCS IDs in plaintext. Instead, the
   $s are written as <$>, resulting in <$>NetBSD<$> and <$>Id<$>.


====================
Part I: User's Guide
====================

 1 Installing a precompiled binary package
 =========================================

This section describes how to find, retrieve and install a precompiled
binary package that someone else already prepared for your type of machine.


 1.1 Where to get
 ================

Precompiled packages are stored on ftp.netbsd.org and its mirrors in the
directory /pub/NetBSD/packages for anon FTP access. Please pick the right
subdirectory there as indicated by "sysctl hw.machine_arch". In that
directory, there is a subdirectory for each category plus a subdirectory
"All" which includes the actual binaries in .tgz-files. The category
subdirectories use symbolic links to those files. (This is the same
directory layout as in /usr/pkgsrc/packages).

This same directory layout applies for CDROM distributions, only that the
directory may be rooted somewhere else, probably somewhere below /cdrom.
Please consult your CDROM's documentation for the exact location!


 1.2 How to use
 ==============

If you have the files on a CDROM or downloaded them to your hard disk, you
can install them with the following command (be sure to su to root first):

	pkg_add /path/to/package.tgz

If you have FTP access and you don't want to download the packages via FTP
prior to installation, you can do this automatically by giving pkg_add an
ftp-URL:

	pkg_add ftp://ftp.netbsd.org/pub/NetBSD/packages/<OS Ver>/<arch>/All/package.tgz

If there is any doubt, the sysctl utility can be used to determine the
<OS Ver>, and <arch> by running "sysctl kern.osrelease hw.machine_arch".

Also note that any prerequisite packages needed to run the package in
question will be installed, too, assuming they are present where you install
from.

After you've installed packages, be sure to have /usr/pkg in your $PATH so
you can actually start the just installed program.


 1.3 A word of warning
 =====================

Please pay very careful attention to the warnings expressed in that manual
page about the inherent dangers of installing binary packages which you did
not create yourself, and the security holes that can be introduced onto
your system by indiscriminate adding of such files.


 2 Installing by Building
 ========================

This assumes that the package is already part of the NetBSD package system.
If it is not, then you are advised to read part II of this document,
"Package Constructor's Guide".


 2.1 Requirements
 ================

To build packages from source on a NetBSD system the "comp" and the "text"
distribution sets must be installed. If you want to build X11 related
packages the "xbase" and "xcomp" distribution sets are required, too.


 2.2 Where to get pkgsrc
 =======================

There are three ways to get pkgsrc. Either as tar file, via SUP, or via
CVS. All three ways are described here. 

To get the package source going, you need to get the pkgsrc.tar.gz file
from ftp://ftp.netbsd.org/pub/NetBSD-current/tar_files/pkgsrc.tar.gz and
unpack it into /usr/pkgsrc.

As an alternative, you can get pkgsrc via the Software Update Protocol,
SUP. To do so, make sure your supfile has a line saying "release=pkgsrc" in
it, see the examples in /usr/share/examples/supfiles, and that the
directory /usr/pkgsrc does exist. Then, simply start "sup -v
/path/to/your/supfile".

To get pkgsrc via CVS, make sure you have cvs installed. If not present on
your system, it can be found as precompiled binary on ftp.netbsd.org. 
To do an initial (full) checkout of pkgsrc, do the following steps:

	% setenv CVSROOT anoncvs@anoncvs.netbsd.org:/cvsroot
	% setenv CVS_RSH ssh 
	% cd /usr
	% cvs checkout -P pkgsrc

This will create the "pkgsrc" directory in your /usr, and all the package
source will be stored under /usr/pkgsrc. To update pkgsrc after the initial
checkout, make sure you have CVS_RSH set as above, then do:

	% cd /usr/pkgsrc
	% cvs -q update -dP


 2.3 Fetching distfiles
 ======================

There is one gotcha: The distribution file (i.e. the unmodified source)
must exist on your system for the packages system to be able to build it.
If it does not, then ftp(1) is used to fetch the distribution files
automatically.

You can overwrite some of the major distribution sites to fit to sites
that are close to your own. Have a look at /usr/pkgsrc/mk/mk.conf.example
to find some examples. This may save some of your bandwidth and time.

When you have selected your settings, install your configuration into
/etc/mk.conf

If you don't have a permanent Internet connection and you want to know
which files to download, "make fetch-list" will tell you what you'll need.
Put these distfiles into /usr/pkgsrc/distfiles.


 2.4 How to build and install
 ============================

Assuming that has been done, become root and change into the relevant
directory. Then you can type

	make

at the shell prompt to build the various components of the package, and

	make install

at the shell prompt to install the various components into the correct
places on your system.

Taking the top system utility as an example, we can install it on our
system by building as shown in appendix A.1.

The program is installed under the default root of the packages tree -
/usr/pkg. Should this not conform to your tastes, simply set the LOCALBASE
variable in your environment, and it will use that value as the root of
your packages tree. So, to use /usr/local, set

	LOCALBASE=/usr/local

in your environment.  Please note that you should use a root which is 
dedicated to packages and not shared with other programs (ie, do not try
and use LOCALBASE=/usr).  This is to prevent possible conflicts between
programs and other files installed by the package system and whatever else
may have been installed there.  There is, of course, one exception to 
this - X11 packages are traditionally installed in the X11 tree. The
definition used to identify the root of the X11 tree is the X11BASE
definition.

It is possible to install X11 packages in the LOCALBASE tree, for
which you must install the xpkgwedge package
(pkgsrc/pkgtools/xpkgwedge) - see section 7.1 for further details.

Some packages look in /etc/mk.conf to alter some configuration options
at build time.  Have a look at /usr/pkgsrc/mk/mk.conf.example to get
an overview of what you can set there.  Environment variables such as
LOCALBASE, and X11BASE can also be set in /etc/mk.conf to save having
to remember to set them each time you want to use pkgsrc.

If you want to deinstall and re-install a binary package that you've
created (see next section), that you put into pkgsrc/packages manually or
that's located on a remote FTP server, you can use the the "bin-install"
target. This target will install a binary package - if available - via
pkg_add, and do a "make package" else. The list of remote FTP sites
searched is kept in the variable BINPKG_SITE, which defaults to
ftp.netbsd.org. Any flags that should be added to pkg_add(8) can be put
into BIN_INSTALL_FLAGS. See pkgsrc/mk/mk.conf.example for more details. 

A final word of warning: If you setup a system that has a non-standard
setting for LOCALBASE (or X11BASE, for that matter), be sure to set that
before any packages are installed, as you can not 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 LOCALBASE of
/usr/pkg, and that you should *not* install any if you use a non-standard
LOCALBASE.


 3 Making precompiled packages
 =============================

 3.1 Packaging a single package
 ==============================
 
Once you have built and installed the package as mentioned above, you can
build it into a "binary package" - you might want to do this so that you
can use the binaries you have just built on another NetBSD system, or to
provide a simple means for others to use your binary package instead of
wasting CPU time - this is done by changing to the appropriate directory in
the pkgsrc tree, and typing the command

	make package

at the shell prompt. This will build and install your package (if not
already done), and then construct a binary package out of the results so
that you can use the pkg_* tools to manipulate this. The binary package is
stored under /usr/pkgsrc/packages, it's in the form of a gzipped file at
the present time. See appendix A.2 for a continuation of the above top
example.

Please see the "submitting" section later in this document on how to submit
such a binary package.


 3.2 Doing a bulk build of all packages
 ======================================

If you want to get a full set of precompiled binary packages, this section
describes how to get them. Beware that the bulk build will remove all
currently installed packages from your your system! Having a FTP server
configured either on the machine doing the bulk builds or on a nearby NFS
server can help to make the packages available to everyone. See ftpd(8) for
more information. If you use a remote NFS server's storage, be sure to not
actually compile on NFS storage, as this slows things down a lot.


 3.2.1 Configuration
 ===================

 3.2.1.1 /etc/mk.conf
 ====================

You may want to set things in /etc/mk.conf.  Look at pkgsrc/mk/mk.conf.example
for details.  You will want to make sure that ACCEPTABLE_LICENSES meet your
local policy:

    BATCH=                  yes          # required for bulk builds 
    DEPENDS_TARGET?=        bulk-install
    PACKAGES?=              ${PKGSRCDIR}/packages/${MACHINE_ARCH}
    OBJMACHINE?=            1                 # use work.${MACHINE_ARCH}
    WRKOBJDIR?=             /usr/tmp/pkgsrc   # build here instead of in pkgsrc
    FAILOVER_FETCH=         yes               # insist on the correct checksum
    PKG_DEVELOPER?=         yes
    ACCEPTABLE_LICENSES=    shareware \
                            fee-based-commercial-use \
                            no-profit \
                            no-commercial-use \
                            non-commercial-use \
                            limited-redistribution \
			    kermit-license \
			    sun-swing-license \
			    sun-jsdk20-license

If you wish to use xpkgwedge for the entire build, then add:

    BULK_PREREQ+=           pkgtools/xpkgwedge

Other packages which must be installed during the bulk build to modify the
build behaviour may be added to the BULK_PREREQ variable.  Note that currently
the only package for which BULK_PREREQ makes sense is xpkgwedge.

 3.2.1.2 build.conf
 ==================

In pkgsrc/mk/bulk, copy ``build.conf-example'' to ``build.conf'' and
edit it, following the comments in that file. This is the config
file that determines where logfiles are generated after the build,
where to mail the build report, where your pkgsrc is located and
which user to su(8) to to do a 'cvs update'.

 3.2.1.3 pre-build.local
 =======================

It is possible to configure the bulk build to perform certain site 
specific tasks at the end of the pre-build stage.  If the file
``pre-build.local'' exists in pkgsrc/mk/bulk it will be executed
(as a sh(1) script) at the end of the usual pre-build stage.  An
example use of pre-build.local is to have the line:

	echo "I do not have enough disk space to build this pig." \
		> games/crafty-book-enormous/$BROKENF

to prevent the system from trying to build a particular package
which requires nearly 3 Gb of disk space.
    
 3.2.2 Other environmental considerations
 ========================================

Drop your favourite login shell in /usr/local, or install it from
/etc/rc.local. Also, if you use a OS version below 1.5 or you still want
to use the pkgsrc version of ssh for some reason, be sure to install 
ssh before starting it from rc.local:

    ( cd /usr/pkgsrc/security/ssh ; make bulk-install )
    if [ -f /usr/pkg/etc/rc.d/sshd ]; then
            /usr/pkg/etc/rc.d/sshd
    fi

Not doing so will result in you being not able to log in via ssh
after the bulk build is finished or if the machine gets rebooted
or crashes. You have been warned! :)


 3.2.3 Operation
 ===============

Make sure you don't need any of the packages still installed.
BEWARE: During the bulk build, ALL packages will be removed!!!
Be sure to remove all other things (from /usr/local, ...).  Become
root and type:

        # cd /usr/pkgsrc
        # sh mk/bulk/build

If for some reason your last build didn't complete (power failure,
system panic, ...), you can continue it by running:

	# sh mk/bulk/build restart

At the end of the bulk run, you will get a summary via mail, and find
build logs in the directory specified by "FTP" in the "build.conf"
file.


 3.2.4 What it does
 ==================

The bulk builds consist of three steps:

1. pre-build: The script updates your pkgsrc via (anon)cvs, then cleans
	out any broken distfiles, and removes all packages installed.

2. the bulk build: This is basically 'make bulk-package' with an optimized
	order in which packages will be built. Packages that don't require
	other packages will be built first, and packages with many depends
	will be built later.

3. post-build: Generates a report that's placed in the directory specified
	in the build.conf file named ``broken.html'', a short version of
	that report will also be mailed to the build's admin.

During the build, a list of broken packages will be compiled in
/usr/pkgsrc/.broken  (or .../.broken.${MACHINE} if OBJMACHINE is set),
individual build logs of broken builds can be found in the package's
directory. These files are used by the bulk-targets to mark broken builds
to not waste time trying to rebuild them, and they can be used to debug
these broken package builds later. 

	
 3.2.5 Disk space requirements
 =============================

Currently, roughly the following requirements are valid for
1.5/i386:

 * Distfiles:                         1500MB (NFS ok)
 * Full set of all binaries:          1000MB (NFS ok)
 * Temp space for compiling:          1500MB (local disk recommended)

For 1.5/alpha:

 * Full set of all binaries:          1300MB (NFS ok)

Note that all pkgs will be deinstalled as soon as they are turned into a
binary package, and that work-sources are removed, so there is no huge
demand to disk space. Afterwards, if the package is needed again, it will
be installed via pkg_add instead of building again, so there are no cycles
wasted by recompiling. 

 3.3 Creating a multiple CD-ROM packages collection
 ==================================================

After your bulk pkgsrc build has completed, you may wish to create a CD-ROM
set of the resulting binary packages to assist in installing packages on
other machines.  The package pkgtools/cdpack provides a simple tool for 
creating the ISO 9660 images.  `cdpack' arranges the packages on the CD-ROM's
in a way that keeps all the dependencies for given package on the same
CD as that package.

 3.3.1 Example of cdpack
 =======================

Complete documentation for cdpack is found in cdpack(1).  The following
short example assumes that the binary packages are left in
/usr/pkgsrc/packages/All and that sufficient disk space exists in /u2
to hold the ISO 9660 images.

  mkdir /u2/images
  pkg_add /usr/pkgsrc/packages/All/cdpack
  rehash
  cdpack /usr/pkgsrc/packages/All /u2/images

If you wish to include a common set of files (COPYRIGHT, README, etc)
on each CD in the collection, then you need to create a directory which
contains these files.  For example

  mkdir /tmp/common
  echo "This is a README" > /tmp/commmon/README
  echo "Another file" > /tmp/common/COPYING
  mkdir /tmp/common/bin
  echo "#!/bin/sh" > /tmp/common/bin/myscript
  echo "echo Hello world" >> /tmp/common/bin/myscript
  chmod 755 /tmp/common/bin/myscript

Now create the images with

  cdpack -x /tmp/common /usr/pkgsrc/packages/All /u2/images

and each image will contain "README", "COPYING", and "bin/myscript"
in their root directories.

Part II: Package Constructor's Guide
====================================

 4 Package components - files, directories and contents
 ======================================================

Whenever you're preparing a package from the FreeBSD ports collection or
doing it from scratch, there are a number of files involved which are
described in the following sections. Special directions are given for what
differs from FreeBSD ports for each file.


 4.1 Makefile
 ============

Building, installation and creation of a binary package are all controlled
by the package's Makefile.

There is a Makefile for each package. This file includes the standard
bsd.pkg.mk file (referenced as "../../mk/bsd.pkg.mk"), which sets all the
definitions and actions necessary for the package to compile and install
itself. The mandatory fields are the DISTNAME which specifies the base name
of the distribution file to be downloaded from the site on the Internet,
MASTER_SITES which specifies that site, CATEGORIES which denotes the
categories into which the package falls, PKGNAME which is the name of the
package, the MAINTAINER name, and the COMMENT variable, which should
contain a one-line description of the package (the package name should not
appear, it will be added automatically). The maintainer variable is there
so that anyone who quibbles with the (always completely correct) decisions
taken by the guy who maintains the port can complain vigorously.

The MASTER_SITES may be set to one of the predefined sites:

	${MASTER_SITE_XCONTRIB}
	${MASTER_SITE_GNU}
	${MASTER_SITE_PERL_CPAN}
	${MASTER_SITE_TEX_CTAN}
	${MASTER_SITE_SUNSITE}
	${MASTER_SITE_GNOME}
	${MASTER_SITE_SOURCEFORGE}

If one of these predefined sites is chosen, you may require the ability to
specify a subdirectory of that site.  Since these macros may expand to
more than one actual site, you MUST use the following construct to specify
a subdirectory:

	${MASTER_SITE_GNU:=subdirectory/name/}

(Note the trailing slash after the subdirectory name.) Use of the deprecated
MASTER_SITE_SUBDIR will not work.

Currently the following values are available for CATEGORIES. If more than
one is used, they need to be separated by spaces:

       archivers  audio      benchmarks   biology       cad     
       chat       comms      converters   cross         databases
       devel      editors    emulators    finance       fonts
       games      graphics   ham          japanese      lang
       mail       math       mbone        misc          net
       news       parallel   print        security      shells
       sysutils   textproc   time         wm            www
       x11

See the NetBSD packages(7) manual page for a description of all available
options and variables.

Please pay attention to the following gotchas, especially when preparing a
package from the FreeBSD ports collection:

 - Remove all MANx and CATx definitions from the package Makefile -
   NetBSD has implemented automatic manual page handling, and these
   definitions are now obsolete.
 - Add MANCOMPRESSED (if not already there) if manpages are installed in
   compressed form by the package; see comment in bsd.pkg.mk
 - Replace /usr/local by ${PREFIX} in all files  (see patches below)
 - Delete any ldconfig commands - this will be done automatically for you
   if the NetBSD platform supports ldconfig, and other measures will be
   taken on platforms which do not support ldconfig (e.g. NetBSD/Alpha)
 - If modifying a package from the FreeBSD ports collection, preserve
   their RCS ID: remove the '$'s around the FreeBSD RCS Id, and insert the
   word FreeBSD, then add a <$>NetBSD<$> (Without the <>s, please remember
   the Terminology section), i.e.:

   before:
	# <$>Id: Makefile,v 1.17 1997/06/16 06:39:51 max Exp <$>

   after:
	# <$>NetBSD<$>
	# FreeBSD Id: Makefile,v 1.17 1997/06/16 06:39:51 max Exp
 - If the package installs any info files, the main info directory file
   needs to be updated to reflect this fact. NetBSD now has an INFO_FILES
   definition, which is used to do this. For example, to install the
   indent.info entry into the info directory file, simply use the

	INFO_FILES=	indent.info

   definition in the package Makefile. If the package does this insertion
   for you, you should specify USE_GTEXINFO in the package Makefile, to
   ensure that the pre-requisite GNU texinfo package is installed on your
   system.
 - Adjust MAINTAINER to be either yourself, if you plan to maintain the
   package for future updates, or set it to the default MAINTAINER
   packages@netbsd.org, as it is unlikely that the FreeBSD people will
   care about NetBSD packages.
 - If there exists a home page for the software in question, please
   add the variable HOMEPAGE right after MAINTAINER. The value of this
   variable should be the URL for the home page.
 - Please also set the COMMENT variable to a short description of the
   package.

 port2pkg (pkgsrc/pkgtools/port2pkg) does many of the mentioned steps
 for you -- operator discretion is advised, though.


 4.2 distinfo
 ============

Most important, the mandatory message digest, or checksum, of all the
distfiles needed for the package to compile, confirming they match the
original file distributed by the author.  This ensures that the
distfile retrieved from the Internet has not been corrupted during
transfer or altered by a malign force to introduce a security hole. 
It is best generated using the "make makesum" command.  The digest
algorithm used was, at one stage, md5, but that was felt lacking
compared to sha1, and so sha1 is now the default algorithm.  The
distfile size is also generated and stored in new distinfo files.
The pkgsrc/pkgtools/digest utility calculates all of the digests
in the distinfo file, and it provides various different algorithms.
At the current time, the algorithms provided are:

	md5, rmd160, sha1, sha256, sha384 and sha512

Some packages have different sets of distfiles on a per architecture
basis. (A good example is www/navigator). These are kept in the
same distinfo file and care should be taken when upgrading such a
package to ensure distfile information is not lost.

The message digest/checksum for all the official patches found in the
patches/ directory (see section 4.3) for the package is also stored in
the distinfo file.  This is a message digest/checksum of all lines in
the patch file except the NetBSD RCS Id.  This file is generated by
invoking "make makepatchsum".


 4.3 patches/*
 =============

This directory contains files that are used by the patch(1) command to
modify the sources as distributed in the distribution file into a form that
will compile and run perfectly on NetBSD. The files are applied
successively in alphabetic order (as returned by a shell "patches/patch-*"
glob expansion), so patch-aa is applied before patch-ab etc.

The patch-?? files should be in diff -bu format, and apply without
a fuzz to avoid problems (To force patches to apply with fuzz you
can set PATCH_FUZZ_FACTOR=-F2).  Furthermore, do not put changes
for more than one file into a single patch-file, as this will make
future modifications more difficult.

Similar, a file should be patches at most once, not several times by
several different patches. If a file needs several patches, they should
be combined into one file.

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. To avoid this, use either the "-U 2" or "-U 1"
option to diff, or let the 'pkgdiff' command from pkgsrc/pkgdiff help you.

If you don't want to worry about the problems in the last two paragraphs
yourself, use pkgdiff from the pkgtools/pkgdiff package, which takes care
of any RCS Ids by itself.

For even more automation, we recommend using mkpatches from the same
package to make a whole set of patches. You just have to backup files
before you edit them to "filename.orig", e.g. with "cp -p filename
filename.orig". If you upgrade a package this way, you can easily compare
the new set of patches with the previously existing one with patchdiff.

When preparing a FreeBSD port for the NetBSD packages system, it's likely
that the FreeBSD port will work on NetBSD. However, check that the person
who ported the software to FreeBSD has not played fast and loose with the
__FreeBSD__ cpp definition without good cause - a simple way to do this is
to do

	grep -i freebsd patches/patch-??

in the package directory.

Besides taking care of any FreeBSDisms, be sure to provide patches to
replace any occurrence of /usr/local in any "Makefile"s in the original
package with ${PREFIX}.

When you have finished a package, remember to generate the checksums
for the patch files by using the "make makepatchsum" command, see
section 4.2.

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 $LOCALPATCHES
directory. The directory tree there is expected to have the same
"category/package" structure as pkgsrc, and patches are expected to be
stored inside these dirs (also known as $LOCALPATCHES/$PKGPATH). For
example if you want to keep a private patch for pkgsrc/graphics/png, keep
it in $LOCALPATCHES/graphics/png/mypatch. All files in the named directory
are expected to be patch files, and they are applied after the "normal"
pkgsrc patches are applied. 


 4.4 pkg/*
 =========

This directory contains several files used to manage the creation of binary
packages. Files from this directory are used in the binary package itself,
and will thus be installed on other machines, so you should be aware that
there is a wider audience than you might think for your comments and
witticisms.

 4.4.1 Mandatory files
 =====================

 * pkg/DESCR:
   A multi-line description of the piece of software.  This should include
   any credits where they are due.  Please bear in mind that others do not
   share your sense of humour (or spelling idiosyncrasies), and that others
   will read everything that you write here.

 * pkg/PLIST:
   This file governs the files that are installed on your system: all the
   binaries, manual pages, etc. There are other directives which may be
   entered in this file, to control the creation and deletion of
   directories, and the location of inserted files.

If you're updating a FreeBSD package to work for NetBSD, please pay special
attention to the following things in pkg/PLIST:

 - If there are any "@exec ldconfig ..." statements, or any "@unexec
   ldconfig ...", delete them. NetBSD works out automatically whether to
   call ldconfig, since some NetBSD architectures do not have ldconfig.
 - Add any missing @dirrm statements
 - Remove any MANx= definitions in the package Makefile

You could also investigate the port2pkg package (pkgsrc/pkgtools/port2pkg),
which does a lot of the donkey work for you.


 4.4.2 Optional files
 ====================

 * pkg/INSTALL:
   Shell script invoked twice during pkg_add. First time after package
   extraction and before files are moved in place, the second time after
   the files to install are moved in place. This can be used to do any
   custom procedures not possible with @exec commands in PLIST. See
   pkg_add(1) and pkg_create(1) for more information.

 * pkg/DEINSTALL:
   This script is executed before and after any files are removed.  It is
   this script's responsibility to clean up any additional messy details
   around the package's installation, since all pkg_delete knows is how to
   delete the files created in the original distribution. See pkg_delete(1)
   and pkg_create(1) for more information.

 * pkg/MESSAGE:
   Display this file after installation of the package.
   Useful for things like legal notices on almost-free software, etc.
   Please note that you can modify variables in it easily by using
   MESSAGE_SUBST in the package's Makefile:
	MESSAGE_SUBST+=  SOMEVAR="somevalue"
   replaces
	${SOMEVAR}
   in pkg/MESSAGE with "somevalue" before displaying the message.


 4.5 scripts/*
 =============

This directory contains any files that are necessary for configuration of
your software, etc. If a script with any of the following names is present,
it will be executed at the appropriate time during the build process:

  pre-fetch          post-fetch
  pre-extract        post-extract
  pre-patch          post-patch
  pre-configure      post-configure     configure
  pre-build          post-build
  pre-install        post-install
  pre-package        post-package

Note that you should NOT define a pre-* or post-* target in the Makefile
which executes the matching scripts/[pre|post]-* script. bsd.pkg.mk runs
any existing Makefile target first, then searches for scripts/* and runs
it using sh(1). Running the script from the Makefile would cause it to
be run twice.

See section 7 for a description of the build process.


 4.6 work/*
 ==========

When you type "make" the distribution files are unpacked into this
directory.  It can be removed by typing

	make clean

at the shell prompt. Also, this directory is used to keep various
timestamp files. 

 4.6 files/*
 ===========

If you have any files that you wish to be placed in the package prior
to configuration or building, you could place these files here and use
a ${CP} command in the pre-configure target to achieve this. 
Alternatively, you could simply diff the file against /dev/null and
use the patch mechanism to manage the creation of this file.


 5 PLIST* issues
 ===============

This section addresses some special issues that one needs to pay attention
to when dealing with the PLIST file (or files, see below!).


 5.1 Miscellaneous
 =================

 * NetBSD RCS Id:
   Be sure to add a RCS ID line as the first thing in any PLIST file you
   write:

	@comment <$>NetBSD<$>

 * ranlib:
   Don't put any ranlib commands into your PLIST files, as they will cause
   troubles when the package is removed. Just make sure the build-process
   does run ranlib - it usually does - and you can leave this out. This is
   usually only a problem when using ports from FreeBSD.

 * ldconfig:
   Don't put any ldconfig commands into your PLIST files, as they will
   cause problems.  All shared object caching is done automatically in
   NetBSD (this takes place when you see the "Automatic shared object
   handling" message), and so you can leave this out.  If any shared
   objects are found in the package, they will be dealt with
   automatically, running ldconfig on platforms which need it, and not
   otherwise.  This is usually only a problem when using ports from
   FreeBSD.  To prevent this automatic handling from taking place,
   set SHLIB_HANDLING to NO in the package Makefile.

 * ${MACHINE_ARCH}, ${MACHINE_GNU_ARCH}:
   Some packages like emacs and perl embed information about which
   architecture they were built on into the pathnames where they install
   their file. To handle this case, PLIST will be preprocessed before
   actually used, and the symbol "${MACHINE_ARCH}" will be replaced by
   what "sysctl -n hw.machine_arch" gives. The same is done if the string
   ${MACHINE_GNU_ARCH} is embedded in PLIST somewhere - use this on
   packages that use GNU autoconfigure.

   Legacy note: There used to be a symbol "<$ARCH>" that was replaced by
   the output of "uname -m", but that's no longer supported and has been
   removed.

 * ${OPSYS}, ${OS_VERSION}:
   Some packages want to embed the OS name and version into some paths.
   to do this, use these two variables in PLIST. ${OPSYS} will be replaced
   by output from "uname -s", ${OS_VERSION} will be set to what "uname -r"
   gives.

 * ${PKGLOCALEDIR}:
   Packages that install locale files should list them in the PLIST as
   "${PKGLOCALEDIR}/locale/de/LC_MESSAGES/..." instead of
   "share/locale/de/LC_MESSAGES/...".  This properly handles the fact that
   different OSes expect locale files to be either in "share" or "lib" by
   default.

 * Manpage-compression:
   Manpages should be installed in compressed form if MANZ is set (in
   bsd.own.mk), and uncompressed otherwise. To handle this in the PLIST
   file, the suffix ".gz" is appended/removed automatically for manpages
   according to MANZ and MANCOMPRESSED being set or not, see above for
   details. This modification of the PLIST file is done on a copy of it,
   not pkg/PLIST itself.

 * Semi-automatic PLIST generation:
   You can use the "make print-PLIST" command to output a PLIST that matches
   any new files since the package was extracted. See below for more 
   information on this target.


 5.2 ${PLIST_SRC}
 ================

To use one or more files as source for the PLIST used in generating the
binary package, set the variable PLIST_SRC to the names of that file(s).
The files are later concatenated using cat(1), and order of things is
important.

 5.3 ${PLIST_SUBST}
 ==================

Similar to MESSAGE_SUBST (see above), you can add variables and their
expansions to this variable in the following way:

	   PLIST_SUBST+=    SOMEVAR="somevalue"

which replaces all occurances of ${SOMEVAR} in the PLIST with "somevalue".
For the values which are replaced by default, please look in bsd.pkg.mk
(and search for PLIST_SUBST).

 5.4 Perl5 modules
 =================

Perl5 modules will install into different places depending on the version
of perl used during the build process.  To address this, the NetBSD
packages system will append lines to the PLIST corresponding to the files
listed in the installed .packlist file generated by most perl5 modules.
This is invoked by defining PERL5_PACKLIST to a space-separated list of
paths to packlist files:

	PERL5_PACKLIST=	${PERL5_SITEARCH}/auto/Pg/.packlist

The variables PERL5_SITELIB, PERL5_SITEARCH, and PERL5_ARCHLIB represent
the three locations in which perl5 modules may be installed, and may be
used by perl5 packages that don't have a packlist.  These three variables
are also substituted for in the PLIST.

 6 Notes on fixes for packages
 =============================

 6.1 CPP defines
 ===============

To port an application to NetBSD, it's usually necessary for the compiler
to be able to judge the system on which it's compiling, and we use
definitions so that the C pre-processor can do this.

The really impatient should just note that a number of the FreeBSD ports
(which are called packages in the NetBSD world) rely on the CPP definition
__FreeBSD__. This should be used sparingly, for FreeBSD-specific features,
but unfortunately this is not always the case. A number also rely on the
fact that the CPU type is an Intel-based little-endian CPU.

To test whether you are working on a 4.4 BSD-derived system, you should use
the BSD definition, which is defined in <sys/param.h> on said systems.

        #include <sys/param.h>

and then you can surround the BSD-specific parts of your port using the
conditional:

	#if (defined(BSD) && BSD >= 199306)
	...
	#endif

Please use the __NetBSD__ definition sparingly - it should only apply to
features of NetBSD that are not present in other 4.4-lite derived BSDs.

You should also avoid defining __FreeBSD__=1 and then simply using the
FreeBSD port, if only from an aesthetic viewpoint.


 6.2 Shared libraries - libtool
 ==============================

NetBSD supports many different machines, with different object formats
like a.out and ELF, and varying abilities to do shared library and
dynamic loading at all. To accompany this, varying commands and options
have to be passed to the compiler, linker etc. to get the Right Thing,
which can be pretty annoying especially if you don't have all the
machines at your hand to test things.  The "libtool" pkg can help
here, as it just "knows" how to build both static and dynamic
libraries from a set our source files, thus being platform
independent. 

Here's how to use libtool in a pkg in seven simple steps:

1. Add USE_LIBTOOL= yes to the package Makefile.

2. For library objects, use "${LIBTOOL} --mode=compile ${CC}" in place of
   ${CC}.  You could even add it to the definition of CC, if only
   libraries are being built in a given Makefile.  This one command will
   build both PIC and non-PIC library objects, so you need not have
   separate shared and non-shared library rules.

3. For the linking of the library, remove any "ar", "ranlib", and "ld
   -Bshareable" commands, and use instead:

	${LIBTOOL} --mode=link ${CC} -o ${.TARGET:.a=.la} ${OBJS:.o=.lo} -rpath ${PREFIX}/lib -version-info major:minor

   Note that the library is changed to have a .la extension, and the
   objects are changed to have a .lo extension.  Change OBJS as necessary.
   This automatically creates all of the .a, .so.major.minor, and ELF
   symlinks (if necessary) in the build directory. Be sure to include
   the -version-info especially when major and minor are zero, as libtool
   will otherwise strip off the shared library version.

   The "-release" option will produce different results for a.out and ELF 
   (excluding symlinks) in only one case. An ELF library of the form
   libfoo-release.so.x.y will have a symlink of libfoo.so.x.y on an a.out
   platform. This is handled automatically.

   The -rpath argument is the install directory of the library being built.

   PLIST should include all of the .a, .la and so, .so.major and .so.major.minor
   entries.

4. When linking shared object (.so) files, i.e. files that are loaded via
   dlopen(3), NOT shared libraries, use "-module -avoid-version" to prevent
   them getting version tacked on.

   PLIST gets the foo.so entry.

5. When linking programs that depend on these libraries _before_ they are
   installed, preface the cc or ld line with "${LIBTOOL} --mode=link", and
   it will find the correct libraries (static or shared), but please be
   aware that libtool will not allow you to specify a relative path in -L
   (such as -L../somelib), because it expects you to change that argument
   to be the .la file.  For example:

	${LIBTOOL} --mode=link ${CC} -o someprog -L../somelib -lsomelib

   should be changed to:

	${LIBTOOL} --mode=link ${CC} -o someprog ../somelib/somelib.la

   and it will DTRT with the libraries.

6. When installing libraries, preface the install or cp command with
   "${LIBTOOL} --mode=install", and change the library name to .la.  For
   example:

	${LIBTOOL} --mode=install ${BSD_INSTALL_DATA} ${SOMELIB:.a=.la} ${PREFIX}/lib

   This will install the static .a, shared library, any needed symlinks,
   and run "ldconfig."

7. In your PLIST, include all of the .a, .la, and so, .so.major and
   .so.major.minor files (this is a change from the previous behaviour).


 6.3 Using libtool on GNU packages that already support libtool
 ==============================================================

Add USE_LIBTOOL=yes and LTCONFIG_OVERRIDE=${WRKSRC}/ltconfig to the
package Makefile as the quick way to bypass the pkg's own libtool.
The pkg's own libtool is made by ltconfig script at do-configure target.
If USE_LIBTOOL and LTCONFIG_OVERRIDE are defined, the specified ltconfig is
overridden, using the devel/libtool instead of the pkg's own libtool.

If your package makes use of the platform independant library for loading
dynamic shared objects, that comes with libtool (libltdl), you should
add USE_LTDL= yes to the Makefile.

Some packages use libtool incorrectly so that the package may not work or
build in some circumstances. Some common errors are

 * The inclusion of a shared object (-module) as a dependent library in an
   executable or library. This in itself isn't a problem if one of two things
   has been done.

   1. The shared object is named correctly, i.e. libfoo.la and not foo.la

   2. The -dlopen option is used when linking an executable.

 * The use of libltdl without the correct calls to initialisation routines.
   The function lt_dlinit() should be called and the macro 
   LTDL_SET_PRELOADED_SYMBOLS included in executables.

 6.4 Gotchas of FreeBSD ports
 ============================

See section 4.1 for Makefile issues (MANx, CATx, MANCOMPRESSED, ldconfig,
RCS IDs) and section 4.3 for gotchas on using patches from FreeBSD ports.

One of the biggest problems with FreeBSD ports is that too many of
them assume they will install into /usr/local, instead of honouring
any ${PREFIX} setting properly.  To change this, add something like the
following into your package Makefile:

pre-configure:
        for f in `find ${WRKDIR} -type f -print|xargs grep -l '/usr/local'`; do
\
                ${SED} -e 's:/usr/local:'${PREFIX}':g' < $$f > $$f.pdone && ${MV} $
$f.pdone $$f; \
        done

This is taken from the sysutils/rtty package; be sure this works for your
package - it may actually make sense to look for some things in /usr/local,
for example. So don't blindly replace all occurrences of /usr/local!

FreeBSD has decided to list manual pages in the package Makefile, with
no corresponding entry in the PLIST.  You will thus need to add any
MAN[1-8ln] files to the PLIST, before deleting the MAN[1-8ln]
definition.  Similarly with MLINKS and CAT[1-8ln] entries.

Side note on manpages in PLIST:  we don't take any notice of any .gz
suffix there, as many FreeBSD ports seem to have .gz pages in PLIST
even when they install manpages without compressing them; rather, we
add our own .gz suffix there according to MANZ.  In short, it does not
matter whether the manual page name in the PLIST has a .gz suffix or
not - if it needs one which is not already there, it will be appended
automatically, and if there is a .gz suffix which is not needed, it
will be deleted automatically.

Some packages use bsd-style .mk files when building, and so any manual
pages that are installed will be gzip-compressed, if MANZ is set, or
not if MANZ is not set.  If the package uses bsd-style .mk files, the
variable MANCOMPRESSED_IF_MANZ should be set to a value of "yes" in
the package Makefile.


 6.5 Feedback to the author
 ==========================

If you have found any bugs in the package you make available, if you had to
do special steps to make it run under NetBSD or if you enhanced the software
in various other ways, be sure to report these changes back to the original
author of the program! With that kind of support, the next release of the
program can incorporate these fixes, and people not using the NetBSD packages
system can win from your efforts.

Support the idea of free software!


 7 The build process
 ===================

The basic steps for building a program are always the same.  First the
program's source (distfile) must be brought to the local system and
then extracted.  After any patches to compile properly on NetBSD 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.  These are exactly the steps performed by the
NetBSD package system, which is implemented as a series of targets in
a central Makefile, /usr/pkgsrc/mk/bsd.pkg.mk.


 7.1 Program location
 ====================

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.

The automatic variable PREFIX indicates where all files of the final
program shall be installed.  It is usually set to $LOCALBASE (/usr/pkg),
or $CROSSBASE for pkgs in the "cross" category, though its value becomes
that of $X11BASE if USE_IMAKE, USE_MOTIF, or USE_X11BASE is set.  The value
${PREFIX} needs to be put into the various places in the program's source
where paths to these files are encoded; see sections 4.3 and 6.2 for
details on this.

When choosing which of these variables to use, follow the following rules:

 * ${PREFIX} always points to the location where the current pkg will be
   installed.  When referring to a pkg's own installation path, use ${PREFIX}.

 * ${LOCALBASE} 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 ${LOCALBASE}.

 * ${X11BASE} is where the actual X11 distribution (from xsrc etc.) is installed.
   When looking for _standard_ X11 includes (not those installed by a pkg), use
   ${X11BASE}.

 * X11 based pkgs are special in that they may be installed in either
   X11BASE or LOCALBASE. To install X11 packages in LOCALBASE, simply
   install the xpkgwedge package (pkgsrc/pkgtools/xpkgwedge).
   If you need to find includes or libraries installed by a pkg that has
   USE_IMAKE, USE_MOTIF, or USE_X11BASE in its pkg Makefile, you need to use
   _both_ ${X11BASE} and ${LOCALBASE}.

 * ${X11PREFIX} should be used to refer to the installed location of an X11
   package. X11PREFIX will be set to ${X11BASE} if xpkgwedge is not installed,
   and to ${LOCALBASE} if xpkgwedge is installed.

 * If xpkgwedge is installed, it is possible to have some packages installed in
   X11BASE and some in LOCALBASE. To determine the prefix of an installed
   package, the EVAL_PREFIX definition can be used. It takes pairs in the
   format DIRNAME=<package>, and the make(1) variable DIRNAME will be set
   to the prefix of the installed package <package>, or ${X11PREFIX} if the
   package is not installed.

   This is best illustrated by example.

   The following lines are taken from pkgsrc/wm/scwm/Makefile:

	EVAL_PREFIX+=	GTKDIR=gtk+
	CONFIGURE_ARGS+=	--with-guile-prefix=${LOCALBASE}	\
				--with-gtk-prefix="${GTKDIR}"		\
				--enable-multibyte

   Specific defaults can be defined for the packages evaluated using
   EVAL_PREFIX, by using a definition of the form:

	GTKDIR_DEFAULT= ${LOCALBASE}

   where "GTKDIR" corresponds to the first definition in the EVAL_PREFIX pair.

 7.2 Main targets
 ================

The main targets used during the build process defined in bsd.pkg.mk are:

 * fetch:
   This will check if the file(s) given in the variables DISTFILES and
   PATCHFILES (as defined in the package's Makefile) are present on the
   local system in /usr/pkgsrc/distfiles. If they are not present, they
   will be fetched using ftp(1) from the site(s) given in the variable
   PATCH_SITES. The location(s) in PATCH_SITES are in the form of URLs
   and can be ftp://- and http://-URLs, as ftp(1) understands both of
   them.

 * checksum:
   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. 

 * extract:
   When the distfiles are present on the local system, they need to be
   extracted, as they are usually in the form of some compressed archive
   format, most commonly .tar.gz. If only some of the distfiles need to be
   uncompressed, the files to be uncompressed should be put into
   EXTRACT_ONLY. If the distfiles are not in .tar.gz format, they can be
   extracted by setting EXTRACT_CMD, EXTRACT_BEFORE_ARGS and/or
   EXTRACT_AFTER_ARGS. 

 * patch:
   After extraction, all the patches named by the PATCHFILES, those present
   in the patches subdirectory of the package as well as in
   $LOCALPATCHES/$PKGPATH (e.g. /usr/local/patches/graphics/png) are
   applied. Patchfiles ending in .Z or .gz are uncompressed before they are
   applied, files ending in .orig or .rej are ignored. Any special options
   to patch(1) can be handed in PATCH_DIST_ARGS. See section 4.3 for more
   details.
   
   By default patch is given special args to make it fail if the
   patches with some lines of fuzz. Please fix (regen) the patches
   so that they apply cleanly. The rationale behind this is that
   patches that apply cleanly may end up being applied in the wrong
   place, and cause severe harm there.

 * configure:
   Most pieces of software need information on the header files,
   system calls, and library routines which are available in NetBSD. 
   This is the process known as configuration, and is usually
   automated.  In most cases, a script is supplied with the source,
   and its invocation results in generation of header files,
   Makefiles, etc.

   If the program doesn't come with its own configure script, one can be
   placed in the package's scripts directory, called "configure". If so, it
   is executed using sh(1).

   If the program's distfile contains its own configure script, this can
   be invoked by setting HAS_CONFIGURE. If the configure script is a GNU
   autoconf script, GNU_CONFIGURE should be specified instead. In either
   case, any arguments to the configure script can be specified in the
   CONFIGURE_ARGS variable, and the configure script's name can be set in
   CONFIGURE_SCRIPT if it differs from the default "configure".

   If the program uses an Imakefile for configuration, the appropriate
   steps can be invoked by setting USE_IMAKE to YES. (If you only want the
   package installed in $X11PREFIX but xmkmf not being run, set USE_X11BASE
   instead!)

 * build:
   Once configuration has taken place, the software can be built on
   NetBSD by invoking $MAKE_PROGRAM on $MAKEFILE with $ALL_TARGET as
   the target to build.  The default MAKE_PROGRAM is "gmake" if
   USE_GMAKE is set, "make" otherwise.  MAKEFILE is set to "Makefile"
   by default, and ALL_TARGET defaults to "all".  Any of these
   variables can be set to change the default build process.

 * install:
   Once the build stage has completed, the final step is to install
   the software in public directories, for users.  As in the
   build-target, $MAKE_PROGRAM is invoked on $MAKEFILE here, but with
   the $INSTALL_TARGET instead, the latter defaulting to "install"
   (plus "install.man", if USE_IMAKE is set). 

If no target is specified, the default is "build". If a subsequent stage
is requested, all prior stages are made: e.g. "make build" will also
perform the equivalent of:

	make fetch
	make checksum
	make extract
	make patch
	make configure
	make build


 7.3 Other helpful targets
 =========================

 * pre/post-*
   For any of the main targets described in the previous section, two
   auxiliary targets exist with "pre-" and "post-" used as a prefix
   for the main target's name.  These targets are invoked before and
   after the main target is called, allowing extra configuration or
   installation steps, for example, which program's configure script
   or install target omitted.  For any of these auxiliary targets,
   scripts of the same name can be placed in the package's
   scripts-subdirectory that will be executed at the given time, see
   section 4.5.

 * do-*:
   Should one of the main targets do the wrong thing, and should there
   be no variable to fix this, you can redefine it with the do-*
   target.  (Note that redefining the target itself instead of the
   do-* target is a bad idea, as the pre-* and post-* targets won't be
   called anymore, etc.) You will not usually need to do this.

 * reinstall:
   If you did a "make install" and you noticed some file was not installed
   properly, you can repeat the installation with this target, which will
   ignore the "already installed" flag. 

 * deinstall:
   This target does a pkg_delete(1) in the current directory,
   effectively de-installing the package. The following variables can
   be used either on the command line or in /etc/mk.conf to tune the
   behaviour: 

    - PKG_VERBOSE:
      Add a "-v" to the pkg_delete(1) command.
      
    - DEINSTALLDEPENDS:
      Remove all packages that require (depend on) the given package.
      This can be used to remove any packages that may have been pulled in
      by a given package, e.g. if "make deinstall DEINSTALLDEPENDS=1" is
      done in x11/kde, this is likely to remove whole KDE. Works by adding
      a "-R" to the pkg_delete command line.

 * update:
   This target causes the current package to be updated to the latest
   version.  The package and all depending packages first get deinstalled,
   then current versions of the corresponding packages get compiled and
   installed.  This is similar to manually noting which packages are
   currently installed, then performing a series of "make deinstall" and
   "make install" (or whatever DEPENDS_TARGET is set to) for these packages.

   You can use the "update" target to resume package updating in case a
   previous "make update" was interrupted for some reason.  However, in
   this case, make sure you don't call "make clean" or otherwise remove
   the list of dependent packages in ${WRKDIR}.  Otherwise you lose the
   ability to automatically update the current package along with the
   dependent packages you have installed.

   Resuming an interrupted "make update" will only work as long as the
   package tree remains unchanged.  If the source code for one of the
   packages to be updated has been changed, resuming "make update" will
   most certainly fail!

   The following variables can be used either on the command line or in
   /etc/mk.conf to alter the behaviour of "make update":

    - DEPENDS_TARGET:
      Install target to use for the updated package and the
      dependent packages.  Defaults to "install".  E.g.
      "make update DEPENDS_TARGET=package"

    - NOCLEAN:
      Don't clean up after updating.  Useful if you want to leave the
      work sources of the updated packages around for inspection or
      other purposes.  Be sure you eventually clean up the source
      tree (see the "clean-update" target below) or you may run into
      troubles with old source code still lying around on your next
      "make" or "make update".

    - REINSTALL:
      Deinstall each package before installing (making ${DEPENDS_TARGET}).
      This may be necessary if the "clean-update" target (see below) was
      called after interrupting a running "make update".

 * clean-update:
   Clean the source tree for all packages that would get updated if
   "make update" was called from the current directory.  This target
   should not be used if the current package (or any of its depending
   packages) have already been deinstalled (e.g., after calling "make
   update") or you may lose some packages you intended to update.
   As a rule of thumb: only use this target _before_ the first time
   you call "make update" and only if you have a dirty package tree
   (e.g., if you used NOCLEAN).  The following variables can be used
   either on the command line or in /etc/mk.conf to alter the behaviour
   of "make clean-update":

    - CLEAR_DIRLIST:
      After "make clean", do not reconstruct the list of directories to
      update for this package.  Only use this if "make update" successfully
      installed all packages you wanted to update.  Normally, this is done
      automatically on "make update", but may have been suppressed by the
      NOCLEAN variable (see above).

 * info:
   This target invokes "pkg_info" for the current package. You can use this
   e.g. to check which version of a package is installed.

 * readme:
   This target generates a README.html file, which can be viewed using a
   browser such as navigator (pkgsrc/www/navigator) or lynx
   (pkgsrc/www/lynx). The generated files contain references to any
   packages which are in the ${PACKAGES} directory on the local host. The
   generated files can be made to refer to URLs based on FTP_PKG_URL_HOST
   and FTP_PKG_URL_DIR. For example, if I wanted to generate README.html
   files which pointed to binary packages on the local machine, in the
   directory /usr/packages, set FTP_PKG_URL_HOST=file://localhost and
   FTP_PKG_URL_DIR=/usr/packages. The ${PACKAGES} directory and its
   subdirectories will be searched for all the binary packages.

 * readme-all: 
   Use this target to create a file README-all.html which contains a
   list of all packages currently available in the NetBSD Packages
   Collection, together with the category they belong to and a short
   description. This file is compiled from the pkgsrc/*/README.html
   files, so be sure to run this _after_ a "make readme".

 * cdrom-readme:
   This is very much the same as the readme: target (see above), but is
   to be used when generating a pkgsrc tree to be written to a CD-ROM.
   This target also produces README.html files, and can be made to refer
   to URLs based on CDROM_PKG_URL_HOST and CDROM_PKG_URL_DIR.

 * show-distfiles:
   This target shows which distfiles and patchfiles are needed to build
   the package. (DISTFILES and PATCHFILES, but not patches/*)

 * show-downlevel:
   This target shows nothing if the package is not installed. If a version
   of this package is installed, but is not the version provided in this
   version of pkgsrc, then a warning message is displayed. This target can
   be used to show which of your installed packages are downlevel, and so
   the old versions can be deleted, and the current ones added.

 * show-pkgsrc-dir:
   This target shows the directory in the pkgsrc hierarchy from which the
   package can be built and installed. This may not be the same directory
   as the one from which the package was installed. This target is intended
   to be used by people who may wish to upgrade many packages on a single
   host, and can be invoked from the top-level pkgsrc Makefile by using the
   target "show-host-specific-pkgs"

 * check-shlibs:
   After a package is installed, check all it's binaries and (on ELF 
   platforms) shared libraries if they find the shared libs they need.
   Run by default if PKG_DEVELOPER is set in /etc/mk.conf.

 * print-PLIST:
   After a 'make install' from a new or upgraded pkg, this prints out an
   attempt to generate a new PLIST from a 'find -newer work/.extract_done'.
   An attempt is made to care for shared libs etc., but it is STRONGLY 
   recommended to review the result before putting it into pkg/PLIST. On
   upgrades, it's useful to diff the output of this command against an already
   existing pkg/PLIST file.

   If the package installs files via tar(1) or other methods that don't update
   file access times, be sure to add these files manually to your pkg/PLIST,
   as 'find -newer' won't catch them!

 * bulk-package:
   Used to do bulk builds. If an appropriate binary package already exists,
   no action is taken. If not, this target will compile, install and
   package it (and it's depends, if PKG_DEPENDS is set properly, see
   section 3.2.1). After creating the binary package, the sources, the
   just-installed package and it's required packages are removed,
   preserving free disk space. 

 * bulk-install:
   Used during bulk-installs to install required packages. If an
   appropriate binary package is available, it will be installed via
   pkg_add. If not, "make bulk-package" will be executed, but the installed
   binary not be removed. A binary package is "appropriate" to be installed
   via pkg_add if:

    - None of the package's files (Makefile, ...) were modified since it
      was built
    - None of the package's required (binary) packages were modified since
      it was built


 8 buildlink.mk methodology
 ==========================

Many packages that install libraries and headers for use in other packages
now have buildlink.mk files in their pkgsrc subdirectory.  The purpose of
these files is two-fold:

  (1) Cause all headers and libraries used by a particular package to be
      found in a known location during the configure and build process.
      These packages are said to be "weakly-buildlinked".

  (2) Cause _only_ those headers and libraries used by a particular package
      to be found during the configure and build process.
      These packages are said to be "strongly-buildlinked".


 8.1 Using buildlink.mk files
 ============================

Goal (1) is accomplished by simply including a package dependency's
buildlink.mk file in a package's Makefile, which does the following:

  (1a) Adds a DEPENDS or BUILD_DEPENDS line for the package;

  (1b) Creates a directory ${BUILDLINK_DIR}, by default set to a
       subdirectory of ${WRKDIR};

  (1c) Links all the headers and libraries for that dependency into
       ${BUILDLINK_DIR}/include and ${BUILDLINK_DIR}/lib, respectively;

  (1d) Prepends -I${BUILDLINK_DIR}/include to CPPFLAGS, CFLAGS, CXXFLAGS,
       and -L${BUILDLINK_DIR}/lib to LDFLAGS;

  (1e) Creates a wrapper script for GTK+-style config scripts, often found
       in GNOME software, that translates -I${LOCALBASE}/include and
       -L${LOCALBASE}/lib into references into ${BUILDLINK_DIR}.

Some packages are for software libraries whose functionality is a part of
recent released versions of NetBSD, e.g. readline, OpenSSL, and ncurses.
For those packages, the buildlink.mk files link the appropriate system
headers and libraries into ${BUILDLINK_DIR} so that goal (1) is still met.
Where possible, the system headers and libraries are renamed when linked
into ${BUILDLINK_DIR} to match the names of their pkgsrc counterparts so
that the files may be referenced under a consistent name.

Goal (2) requires some work on the part of the package builder.  As all
headers and libraries used by a package may be found in ${BUILDLINK_DIR},
and -I${BUILDLINK_DIR}/include and -L${BUILDLINK_DIR}/lib are already passed
to the compiler, it is no longer necessary to pass -I${LOCALBASE}/include or
-L${LOCABASE}/lib to the compiler.  Therefore, those lines should be removed
from package Makefiles, and where necessary, the package sources should be
patched to do the same.  Also, if a package uses X11, then by including
mk/x11.buildlink.mk, -I${BUILDLINK_X11_DIR}/include and
-L${BUILDLINK_X11_DIR}/lib are also passed to the compiler instead of the
corresponding directories in ${X11BASE}.  Also, if USE_BUILDLINK_ONLY is
defined, then -L${LOCALBASE}/lib is not automatically added to LDFLAGS in
bsd.pkg.mk.


 8.2 Writing buildlink.mk files
 ==============================

Most of the work done by buildlink.mk files is encapsulated and shared
through bsd.buildlink.mk, which is included by packages' buildlink.mk files.
Please see the comments at the top of bsd.buildlink.mk for complete
documentation on how to use the file.  A simple example of a buildlink.mk
for a mythical package foo follows:

> .include "../../mk/bsd.buildlink.mk"
> 
> BUILDLINK_DEPENDS.foo?=	foo>=1.0
> DEPENDS+=			${BUILDLINK_DEPENDS.foo}:../../category/foo
> 
> EVAL_PREFIX+=			BUILDLINK_PREFIX.foo=foo
> BUILDLINK_FILES.foo=		include/foo.h
> BUILDLINK_FILES.foo+=		include/bar.h
> BUILDLINK_FILES.foo+=		lib/libfoo.*
> 
> # We need the libraries to be called "libbar.*".
> BUILDLINK_TRANSFORM.foo=	-e "s|libfoo|libbar|g"
> 
> BUILDLINK_TARGETS+=		foo-buildlink
> 
> pre-configure: foo-buildlink
> foo-buildlink: _BUILDLINK_USE


 8.3 Converting packages to use buildlink.mk files
 =================================================

The process of converting existing packages to use the buildlink.mk
infrastructure is fairly straightforward.  If a dependency on a particular
package is required for its libraries and headers, then rather than
directly adding a dependency on that package, include that package's
buildlink.mk instead.  The following variables may also be replaced with
buildlink.mk files:

    USE_CURSES	-->	.include "../../devel/ncurses/buildlink.mk"
    USE_LIBINTL	-->	.include "../../devel/gettext-lib/buildlink.mk"
    USE_LTDL	-->	.include "../../devel/libtool/buildlink.mk"
    USE_MESA	-->	.include "../../graphics/Mesa/buildlink.mk"
    USE_MOTIF	-->	.include "../../x11/lesstif/buildlink.mk"
    USE_MOTIF12	-->	.include "../../x11/lesstif12/buildlink.mk"
    USE_SSL	-->	.include "../../security/openssl/buildlink.mk"
    USE_X11	-->	.include "../../mk/x11.buildlink.mk"
    USE_XAW	-->	.include "../../mk/xaw.buildlink.mk"
    USE_XPM	-->	.include "../../graphics/xpm/buildlink.mk"

Packages that have an explicit dependency on ncurses should set USE_NCURSES
to the reason why the system curses is insufficient, and include
"../../devel/ncurses/buildlink.mk" afterwards.  This helps to identify
where the system curses differs from ncurses, and when the development of
the system curses catches up in functionality, the USE_NCURSES setting may
be removed.

Packages that use OpenSSL that require a specific version of OpenSSL should
define USE_OPENSSL_VERSION to the minimum version number required prior to
including "../../security/openssl/buildlink.mk".  The version number is the
hexadecimal number found in <openssl/opensslv.h>, or the variables
OPENSSL_VERSION_{095A,096,096A,096B} may be used.

The use of EVAL_PREFIX to find the installation prefix for packages may be
removed since references to package library and header files are found
through ${BUILDLINK_DIR}.  If the required dependency pattern for a package
differs from the default specified in the package's buildlink.mk file, then
it may be set by defining BUILDLINK_DEPENDS.<pkgname> in the Makefile to
the dependency pattern required.

Packages will still need LDFLAGS to be set to include the appropriate rpath
settings in order for built packages to find libraries.  LDFLAGS should
still contain -Wl,-R${LOCALBASE}/lib, and -Wl,-R${X11BASE}/lib if the
package requires the X11 libraries.  -Wl,-R should never refer to a
${BUILDLINK_DIR} library directory, and all such references should be
purged from the build.

A package that builds correctly with USE_BUILDLINK_ONLY set should have
that setting added to its Makefile to note that it doesn't use any
libraries or headers in ${LOCALBASE} directly, but rather references them
only through ${BUILDLINK_DIR}.  Note that you MUST check the build output
to verify that no references to ${LOCALBASE} directories occurred during
the configure or build process, or else the package cannot be marked as
USE_BUILDLINK_ONLY.


 9 Debugging
 ===========

To check out all the gotchas when building a package (wither from
a FreeBSD port, or from scratch), here are the steps that I do in
order to get a package working. Please note this is basically the
same as what was explained in the previous sections, only with some
debugging aids.

 - Make sure PKG_DEVELOPER=1 is in /etc/mk.conf
 - Retrieve port from FreeBSD collection
 - Fix RCS-ID in the package's Makefile, see section 4.1. 
 - Import unchanged FreeBSD source (ONLY if you have cvs access, not needed
   otherwise):
   (cd .../pkgsrc/category/pkgname ; cvs import pkgsrc/category/pkgname \
	FREEBSD FreeBSD-current-yyyy-mm-dd)
 - If you did a CVS import, check it out to apply the following fixes
   (not needed if you don't have CVS access!)
 - Look at Makefile, fix if necessary; see section 4.1. 
 - Look at patches, remember if not appropriate
 - Have a look at pkg/PLIST, add a "@comment <$>NetBSD<$>" line at the
   beginning of any PLIST file (see section 5). 
 - make
 - If something is not ok, fix; for patches: fix the file, then re-generate
   the diff: 'diff -bu foo.orig foo >../../patches/patch-xx' (mv patch-xx
   patch-xx.orig before); If there's no foo.orig from a previous patch, be
   sure to have an old version of the file somewhere; re-iterate :)
 - If all builds OK: touch /tmp/bla
 - make install
 - find /usr/pkg/ /usr/X11R6/ -newer /tmp/bla >/tmp/x
   (or whatever you set LOCALBASE and X11BASE to)
 - pkg_delete blub
 - find /usr/pkg/ /usr/X11R6/ -newer /tmp/bla (or diff against output of
   'make print-PLIST'): if this brings up any files, that are missing in
   pkg/PLIST*; add them.
 - Compare pkg/PLIST* against /tmp/x, fix the former one
   ( sort /tmp/x >/tmp/x2 ; sort pkg/PLIST >/tmp/P ; sdiff /tmp/x2 /tmp/P )
 - make reinstall && make package
 - pkg_delete blub
 - "find /usr/pkg/ /usr/X11R6/ -type f -newer /tmp/bla" shouldn't find anything
   now
 - pkg_add .../blub.tgz
 - Play with it :)
 - pkg_delete - still no file should be left (re-run above find)
 - make clean && touch /tmp/bla && make install && make clean && make deinstall
   then run the find again. Yes, some software authors write Makefiles that
   install files during the build target. Sigh. Re-run the find, and fix the
   PLIST. Repeat until certain the software does not install any files that
   aren't in PLIST.
 - submit (or commit, if you have cvs access); see section 10.


 10 FAQs & features of the package system
 ========================================

 10.1 Packages using GNU autoconfig
 ==================================

If your package uses GNU autoconf, add the following to your package's
Makefile:

> GNU_CONFIGURE= yes

Note that this appends --prefix=${PREFIX} to CONFIGURE_ARGS, so you don't
have to do that yourself, and this may not be what you want.


 10.2 Other distrib methods than .tar.gz
 =======================================

If your package uses a different distribution method from .tar.gz, take a
look at the package for editors/sam, which uses a gzipped shell archive
(shar), but the quick solution is to set EXTRACT_SUFX to the name after the
DISTNAME field, and add the following to your package's Makefile:

> EXTRACT_SUFX=   .msg.gz
> EXTRACT_CMD=            zcat
> EXTRACT_BEFORE_ARGS=
> EXTRACT_AFTER_ARGS=     |sh


 10.3 Packages not creating their own subdirectory
 =================================================

Your package doesn't create a subdirectory for itself (like GNU software
does, for instance), but extracts itself in the current directory: see
editors/sam again, but the quick answer is:

> NO_WRKSUBDIR=   yes


 10.4 Custom configuration process
 =================================

Your package uses a weird Configure script: See the top package, but the
quick answer is:

> HAS_CONFIGURE=          yes
> CONFIGURE_SCRIPT=       Configure
> CONFIGURE_ARGS+=        netbsd13


 10.5 Packages not building in their DISTNAME directory
 ======================================================

Your package builds in a different directory from its base DISTNAME - see
tcl and tk packages:

> WRKSRC=         ${WRKDIR}/${DISTNAME}/unix


 10.6 How to fetch all distfiles at once
 =======================================

You would like to download all the distfiles in a single batch from work or
university, where you can't run a "make fetch". But there's no archive of
the distfiles on ftp.netbsd.org and the one on ftp.freebsd.org contains
many distfiles for which there are no ports (yet).

The answer here is to do a "make fetch-list" in /usr/pkgsrc, carry the 
resulting list to your machine at work/school and use it there If you don't
have a NetBSD-compatible ftp(1) (like lukemftp) at work, don't forget to
set FETCH_CMD to something that fetches an URL:

At home:
	cd /usr/pkgsrc
	make fetch-list FETCH_CMD=wget DISTDIR=/tmp/distfiles >/tmp/fetch.sh
	scp /tmp/fetch.sh work:/tmp

At work:
	sh /tmp/fetch.sh
	tar up /tmp/distfiles and take it home

If you have a machine running NetBSD, and you want to get *all* distfiles
(even ones that aren't for your machine architecture), you can do so by
using the above-mentioned 'make fetch-list'-approach, or fetch the distfiles
directly by typing:

	make mirror-distfiles

If you even decide to ignore NO_{SRC,BIN}_ON_{FTP,CDROM}, then you can 
get all & everything by typing

	make fetch NO_IGNORE=yes


 10.7 How to fetch files from behind a firewall
 ==============================================

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 orpheus.amdahl.com is one of the firewalls, and
it uses port 80 as the proxy port number. So the proxy environment
variables look like:

	ftp_proxy=ftp://orpheus.amdahl.com:80/
	http_proxy=http://orpheus.amdahl.com:80/


 10.8 If your patch contains an RCS ID
 =====================================

See section 4.3 on how to remove RCS IDs from patch files. 


 10.9 How to pull in variables from /etc/mk.conf
 ===============================================

The problem with package-defined variables that can be overridden via
MAKECONF or /etc/mk.conf is that make(1) expands a variable as it is
used, but evaluates preprocessor like statements (.if, .ifdef and
.ifndef) as they are read.  So, to use any variable (which may be set
in /etc/mk.conf) in one of the .if* statements, the file /etc/mk.conf
must be included before that .if* statement.

Rather than have a number of ad-hoc ways of including /etc/mk.conf,
should it exist, or MAKECONF, should it exist, include the
pkgsrc/mk/bsd.prefs.mk file in the package Makefile before any
preprocessor-like .if, .ifdef, or .ifndef statements:

	.include "../../mk/bsd.prefs.mk"

	.if defined(USE_MENUS)
	...
	.endif


 10.10 Is there a mailing list for pkg-related discussion?
 =========================================================

Yes. We are using tech-pkg@netbsd.org for discussing package related
issues. To subscribe do:

    echo subscribe tech-pkg | mail majordomo@netbsd.org


 10.11 How do i tell "make fetch" to do passive FTP?
 ===================================================

This depends on which utility is used to retrieve distfiles. From
bsd.pkg.mk, FETCH_CMD is assigned the first available command from the
following list:

/usr/bin/fetch
${LOCALBASE}/bsd/bin/ftp
/usr/bin/ftp

On a default NetBSD install, this will be /usr/bin/ftp, 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
/etc/mk.conf file: PASSIVE_FETCH=1

Having that option present will prevent /usr/bin/ftp from falling back to
active transfers.


 10.12 Dependencies on other packages
 ====================================

Your package may depend on some other package being present - and there are
various ways of expressing this dependency. NetBSD supports the
BUILD_DEPENDS and DEPENDS definitions (beware: the DEPENDS definition is
not the same as FreeBSD's deprecated one, and NetBSD does not use the
FreeBSD LIB_DEPENDS definition any more - it proved problematic on ELF
NetBSD platforms).

The basic difference between the two definitions is as follows:  the
DEPENDS definition registers that pre-requisite in the binary package,
whilst the BUILD_DEPENDS definition does not.

This means that if you only need a package present whilst you are building,
it should be noted as a BUILD_DEPENDS.

The format for a BUILD_DEPENDS and a DEPENDS definition is:

	<pre-req-package-name>:../../<category>/<pre-req-package>

Please note that the "pre-req-package-name" may include any of the wildcard
version numbers recognised by pkg_info(1).

(a) If your package needs to use another package to build itself, this
is specified using the BUILD_DEPENDS definition.

	BUILD_DEPENDS+=  autoconf-2.13:../../devel/autoconf

(b) If your package needs a library with which to link, this is
specified using the DEPENDS definition.  An example of this is the
print/lyx package, which uses the xpm library, version 3.4j to build.

	DEPENDS+=       xpm-3.4j:../../graphics/xpm

You can also use wildcards in package dependences:

	DEPENDS+=	xpm-*:../../graphics/xpm

Note that such wildcard dependencies are retained when creating binary
packages.  The dependency is checked when installing the binary
package and any package which matches the pattern will be used. 
Wildard dependencies should be used with care.

For example, if a package needs any version of Tk installed, but does
not require an explicit version of Tk:

	DEPENDS+=	tk-*:../../x11/tk80

would also match e.g. tk-postgresql-6.5.3, which is not what was
needed. ALWAYS ensure that the wildcard doesn't match more than it should,
and perhaps use version numbers to make certain:

	BUILD_DEPENDS+=	perl-5.*:../../lang/perl

(c) If your package needs some executable to be able to run correctly, this
is specified using the DEPENDS definition. The print/lyx package needs to
be able to execute the latex binary from the teTex package when it runs,
and that is specified:

	DEPENDS+=        teTex-*:../../print/teTeX 

The comment about wildcard dependencies from previous paragraph
applies here, too.

If your package needs files from another package to build, see the
first part of the "do-configure" target print/ghostscript5 package (it
relies on the jpeg sources being present in source form during the
build):

	if [ ! -e ${BUILD_ROOT}/graphics/jpeg/${WRKDIR:T}/jpeg-6b ]; then \
		cd ../../graphics/jpeg && ${MAKE} extract;              \
	fi

Please also note the BUILD_USES_MSGFMT and BUILD_USES_GETTEXT_M4 definitions,
which are provided as convenience definitions.  The former works out whether
msgfmt(1) is part of the base system, and, if it isn't, installs the
devel/gettext package.  The latter adds a build dependency on either an
installed version of an older gettext package, or if it isn't, installs the
devel/gettext-m4 package.


 10.13 Conflicts with other packages
 ===================================

Your package may conflict with other packages a user might already have
installed on his system, e.g. if your package installs the same set of
files like another package in our pkgsrc tree.

In this case you can set CONFLICTS to a space separated list of packages
(including version string) your package conflicts with.

For example pkgsrc/x11/Xaw3d and pkgsrc/x11/Xaw-Xpm install provide the
same shared library, thus you set in pkgsrc/x11/Xaw3d/Makefile:

CONFLICTS=      Xaw-Xpm-*

and in pkgsrc/x11/Xaw-Xpm/Makefile:

CONFLICTS=      Xaw3d-*

Packages will automatically conflict with other packages with the name prefix
and a different version string. "Xaw3d-1.5" e.g. will automatically conflict
with the older version "Xaw3d-1.3".


 10.14 Software which has a WWW Home Page
 ========================================

The NetBSD packages system now supports a variable called HOMEPAGE.
If the software being packaged has a home page, the Makefile should
include the URL for that page in the HOMEPAGE variable. The definition
of the variable should be placed immediately after the MAINTAINER
variable.


 10.15 How to handle modified distfiles with the 'old' name
 ==========================================================

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 md5 checksum will no longer match. The correct way to work around this
is to update the package's md5 checksum to match the package on the master
site (beware, any mirrors may not be up to date yet!), and to remove the 
old distfile from ftp.netbsd.org's /pub/NetBSD/packages/distfiles directory.
Furthermore, a mail to the package's author seems appropriate making sure
the distfile was really updated on purpose, and that no trojan horse or so
crept in.


 10.16 What does "Don't know how to make /usr/share/tmac/tmac.andoc" mean?
 =========================================================================

When compiling the pkgsrc/pkgtools/pkg_install package, you get the error
from make that it doesn't know how to make /usr/share/tmac/tmac.andoc? This
indicates that you don't have installed the "text" set on your machine
(nroff, ...). It is recommended to do that.

In the case of the pkg_install package, you can get away with setting
NOMAN=YES either in the environment or in /etc/mk.conf.


 10.17 How to handle incrementing versions when fixing an existing package
 =========================================================================

When making fixes to an existing package it can be useful to change
the version number in PKGNAME. To avoid conflicting with future versions
by the original author, use a 'nb1' suffix (later versions should
increment this to give 'nb2' and so on).


 10.18 "Could not find bsd.own.mk" - what's wrong?
 =================================================

You didn't install the compiler set, comp.tgz, when you installed your
NetBSD machine. Please get it and install it, by extracting it in /:

	tar --unlink -pvxf .../comp.tgz

comp.tgz is part of every NetBSD release, please get the one matching 
the release you have installed (determine via "uname -r").


 10.19 Restricted packages
 =========================

Some licenses restrict how software may be re-distributed.  In order to
satisfy these restrictions, the package system defines five make variables
that can be set to note these restrictions:

    - RESTRICTED:
      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.

    - NO_BIN_ON_CDROM:
      Binaries may not be placed on CD-ROM.  Set this variable to
      ${RESTRICTED} whenever a binary package may not be included
      on a CD-ROM.

    - NO_BIN_ON_FTP:
      Binaries may not be placed on an ftp server.  Set this
      variable to ${RESTRICTED} whenever a binary package may not
      not be made available on the internet.

    - NO_SRC_ON_CDROM:
      Distfiles may not be placed on CD-ROM.  Set this variable to
      ${RESTRICTED} if re-distribution of the source code or other
      distfile(s) is not allowed on CD-ROMs.

    - NO_SRC_ON_FTP:
      Distfiles may not be placed on FTP.  Set this variable to
      ${RESTRICTED} if re-distribution of the source code or other
      distfile(s) via the internet is not allowed.

Please note that the use of NO_PACKAGE, IGNORE, NO_CDROM, or other generic
make variables to denote restrictions is deprecated, because they
unconditionally prevent users from generating binary packages!

 10.20 Packages using (n)curses
 ==============================

Some packages need curses functionality that wasn't present in NetBSD's own
curses prior to 1.4Y. For packages using such functionality there are two
options, setting USE_CURSES or including ../../devel/ncurses/buildlink.mk
in the package's Makefile.


 10.20.1 USE_CURSES
 ===================

If USE_CURSES is set in a package's Makefile, NEED_NCURSES is set
automatically to YES or NO, depending on whether a dependency on ncurses is
needed on this system. You can use this variable to e.g. add arguments to
configure to tell the package whether to use ncurses.

Additionally, you can set REPLACE_NCURSES to some filenames; in each of
these files, each occurrence of 'ncurses' is replaced by 'curses' if the
package doesn't need ncurses. You may need this in some cases if ncurses
are installed, and the package's configure script prefers ncurses.

For example, in mail/mutt, the relevant lines are:
USE_CURSES=		YES
REPLACE_NCURSES=	configure configure.in
[...]
.include "../../mk/bsd.prefs.mk"

.if defined(NEED_NCURSES) && ${NEED_NCURSES} == "YES"
CONFIGURE_ARGS+=	--with-curses=${LOCALBASE}
.endif

Please note that the check for NEED_NCURSES has to be below the
inclusion of bsd.prefs.mk, since the variable is set there.


 10.20.2 devel/ncurses/buildlink.mk
 ==================================

If ../../devel/ncurses/buildlink.mk is included in a package's Makefile,
then a curses library and headers with ncurses functionality are linked
into ${BUILDLINK_DIR} at pre-configure time.  If ncurses is needed, then a
dependency on ncurses is added to the package, otherwise, if the system
curses is sufficient, then the library and headers are linked into
${BUILDLINK_DIR} with ncurses names.  If ncurses is actually required, then
define USE_NCURSES in the package's Makefile.


 10.21 Automated security check
 ==============================

Please be aware that there can often be bugs in third-party software,
and some of these bugs can leave a machine vulnerable to exploitation
by attackers.  In an effort to lessen the exposure, the NetBSD
packages team maintains a database of known-exploits to packages which
have at one time been included in pkgsrc.  The database can be
downloaded automatically, and a security audit of all packages
installed on a system can take place.  To do this, install the
pkgsrc/security/audit-packages package.  It has two components:

(1) download-vulnerability-list, an easy way to download a list of the
security vulnerabilities information.  This list is kept up to date by
the NetBSD security officer and the NetBSD packages team, and is
distributed from the NetBSD ftp server:

	ftp://ftp.netbsd.org/pub/NetBSD/packages/distfiles/vulnerabilities

(2) audit-packages, an easy way to audit the current machine, checking
each vulnerability which is known.  If a vulnerable package is
installed, it will be shown by output to stdout, including a description
of the type of vulnerability, and a URL containing more information.

Use of the audit-packages package is strongly recommended.

The following message is displayed as part of the audit-packages
installation procedure:

  ======================================================================
  You may wish to have the vulnerabilities file downloaded daily so that
  it remains current.  This may be done by adding an appropriate entry
  to the root users crontab(5) entry.  For example the entry
  
  # download vulnerabilities file
  0 3 * * * ${PREFIX}/sbin/download-vulnerability-list >/dev/null 2>&1
  
  will update the vulnerability list every day at 3AM.
  
  In addition, you may wish to run the package audit from the daily
  security script.  This may be accomplished by adding the following
  lines to /etc/security.local
  
  if [ -x ${PREFIX}/sbin/audit-packages ]; then
          ${PREFIX}/sbin/audit-packages
  fi
  ======================================================================


Note to package developers: When a vulnerability is found, this should be
noted in localsrc/security/advisories/pkg-vulnerabilities, and after the
commit of that file, it should be copied to
/pub/NetBSD/packages/distfiles/vulnerabilities on ftp.netbsd.org. 


 10.22 What's the proper way to create an account from a package?
 ================================================================

Look at what e.g. sysutils/amanda-common/{Makefile,pkg/INSTALL} do.


 11 Submitting & Committing
 ==========================

 11.1 Submitting your packages
 =============================

You have to separate between binary and "normale" (source) packages here:

 * precompiled binary packages:
   Our policy is that we accept binaries only from NetBSD developers to
   guarantee that the packages don't contain any trojan horses etc. 
   This is not to piss anyone off 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. 

 * packages:
   First, check that your package is complete, compiles and runs well; see
   section 8 and the rest of this document. Next, generate a gzipped
   tar-file of all the files needed for the package, preferably with all
   files in a single directory. Place this tar-file to a place where the
   package maintainers can fetch it using FTP or HTTP (WWW). Finally,
   send-pr with category "pkg", a synopsis which includes the package name
   and version number, a short description of your package
   (contents of the COMMENT variable are OK) and the URL of your tar-file.

   You will be notified if your send-pr has been addressed so you can remove
   the tar-file. 

   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.


 11.2 Committing: Importing the package into CVS
 ===============================================

This section is only of interest for NetBSD developers with write
access to the NetBSD pkgsrc repository. Please remember that cvs
imports files relative to the cwd, and that the pathname that you
give the "cvs import" command is so that it knows where to place
the files in the repository.  Newly created packages should be
imported with a vendor tag of "TNF" and a release tag of "pkgsrc-base",
e.g:

	cd .../pkgsrc/<category>/<pkgname>
	cvs import pkgsrc/<category>/<pkgname> TNF pkgsrc-base


and remember to move the directory from which you imported out of
the way, or cvs will complain the next time you "cvs update" your
source tree.

Packages derived from a FreeBSD port should be imported with a vendor tag
of "FREEBSD" and a release tag of "FreeBSD-current-YYYY-MM-DD" (YYYY-MM-DD
being the date when the snapshot of the port were taken form the FreeBSD
tree), and then doing the necessary modifications by normal CVS operations.
E.g:

	cd .../pkgsrc/<category>/<pkgname>
	cvs import pkgsrc/<category>/<pkgname> FREEBSD FreeBSD-current-1998-04-01
	cvs rm patches/patch-a
	cvs add patches/patch-aa
	cvs ci

Please note all package updates/additions in doc/pkg-CHANGES! 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
www.netbsd.org and other sites.


 12 A simple example of a package: bison
 =======================================

I checked to find a piece of software that isn't in the FreeBSD ports
collection, and picked GNU bison. Quite why someone would want to have
bison when Berkeley yacc is already present in the tree is beyond me, but
it's useful for the purposes of this exercise.


 12.1 files
 ==========

The file contents in this section must be used without the "> " prefix.


 12.1.1 Makefile
 ===============

> # <$>NetBSD<$>
>

 12.1.4 Checking a package "pkglint"
 ===================================

The NetBSD package system comes with a tool called "pkglint" (located in the
directory "pkgsrc/pkgtools/pkglint") which helps to check the contents of these
files. After installation it is quite easy to use, just change to the
directory of the package you wish to examine and execute "pkglint":

> tron@lyssa:/usr/pkgsrc/devel/bison>pkglint
> OK: checking pkg/DESCR.
> OK: checking Makefile.
> OK: checking distinfo.
> OK: checking patches/patch-aa.
> looks fine.

Depending on the supplied command line arguments (see "man pkglint") more
verbose checks will be performed. Use e.g. "pkglint -v" for a very verbose
check.


 12.2 Steps for building, installing, packaging
 ==============================================

Create the directory where the package lives, plus any auxiliary directories:

> root@pumpy:/u/pkgsrc/lang(1765)# cd /usr/pkgsrc/lang
> root@pumpy:/u/pkgsrc/lang(1765)# mkdir bison
> root@pumpy:/u/pkgsrc/lang(1766)# cd bison
> root@pumpy:/u/pkgsrc/lang/bison(1768)# mkdir files patches pkg

Create Makefile, pkg/DESCR and pkg/PLIST as in section 11.1,
then continue with fetching the distfile:

> root@pumpy:/u/pkgsrc/lang/bison(1769)# make fetch
> >> bison-1.25.tar.gz doesn't seem to exist on this system.
> >> Attempting to fetch from ftp://prep.ai.mit.edu/pub/gnu//.
> Requesting ftp://prep.ai.mit.edu/pub/gnu//bison-1.25.tar.gz (via ftp://orpheus.amdahl.com:80/)
> ftp: Error retrieving file: 500 Internal error
>  
> >> Attempting to fetch from ftp://wuarchive.wustl.edu/systems/gnu//.
> Requesting ftp://wuarchive.wustl.edu/systems/gnu//bison-1.25.tar.gz (via ftp://orpheus.amdahl.com:80/)
> ftp: Error retrieving file: 500 Internal error
>  
> >> Attempting to fetch from ftp://ftp.freebsd.org/pub/FreeBSD/distfiles//.
> Requesting ftp://ftp.freebsd.org/pub/FreeBSD/distfiles//bison-1.25.tar.gz (via ftp://orpheus.amdahl.com:80/)
> Successfully retrieved file.

Generate the checksum of the distfile into distinfo:

> root@pumpy:/u/pkgsrc/lang/bison(1770)# make makesum

Now compile:

> root@pumpy:/u/pkgsrc/lang/bison(1777)# make

Everything seems OK, so install the files:

> root@pumpy:/u/pkgsrc/lang/bison(1785)# make install
> >> Checksum OK for bison-1.25.tar.gz.
> ===>  Installing for bison-1.25

You can now use bison, and also - if you decide so - remove it with
"pkg_delete bison-1.25". Should you decide that you want a binary package,
do this now:

> root@pumpy:/u/pkgsrc/lang/bison(1786)# make package
> >> Checksum OK for bison-1.25.tar.gz.
> ===>  Building package for bison-1.25
> Creating package bison-1.25.tgz
> Registering depends:.
> Creating gzip'd tar ball in '/u/pkgsrc/lang/bison/bison-1.25.tgz'

Now that you don't need the source and object files any more, clean up:

> root@pumpy:/u/pkgsrc/lang/bison(1787)# make clean

To create:
 - cd /usr/pkgsrc ; make install ; make package
 - upload /usr/pkgsrc/packages to
   ftp://ftp.netbsd.org/pub/NetBSD/packages/\
    `uname -r | sed 's@\.\([0-9]*\)[\._].*@\.\1@'`/`sysctl -n hw.machine_arch`
 - if necessary ln -s `sysctl -n hw.machine` `sysctl -n hw.machine_arch`

Disk space needed: unknown.

Packages for a release version of NetBSD should be uploaded to the
directory major.minor corresponding to the appropriate release.  Packages
for NetBSD with versions such as "1.5.1" should be uploaded to the "1.5"
directory, stripping the tiny number off the directory name.  For packages
that need to be tightly coupled with the OS Version, such as LKM's, you
may create a major.minor.tiny release directory, and place those packages
therein.  Such packages should be marked with the variable
"OSVERSION_SPECIFIC=yes" to mark them in some way for binary package 
builders.
