+.TH PKGBUILD 5 "Feb 06, 2007" "PKGBUILD version \*(VR" "\*(DS Files"
+.SH NAME
+PKGBUILD \- \*(DS package build description file
+.SH DESCRIPTION
+This manual page is meant to describe general rules about PKGBUILDs. Once
+a PKGBUILD is written, the actual package is built using \fBmakepkg\fR and
+installed with \fBpacman\fR.
+
+\fBNOTE:\fR If you have a local copy of the Arch Build System (ABS) tree
+on your computer, you can copy the PKGBUILD.proto file to your new package
+build directory and edit it from there. To acquire/sync the ABS tree, use
+the \fBabs\fR script included with pacman/makepkg.
+
+.SS Quick PKGBUILD Explanation
+For an example of a PKGBUILD, see the \fBEXAMPLE\fR section.
+
+\fIpkgname\fR defines the package name. It should not contain any uppercase
+letters. \fIpkgversion\fR defines the actual package version as given by the
+developers of the package. No dashes are allowed. \fIpkgrel\fR allows for
+\*(DS-specific changes to the package or corrections to a PKGBUILD
+without an upstream version change. The value should be an integer.
+\fIpkgdesc\fR is a short one-line description for the package, usually taken
+from the project's homepage or manpage. It is preferable to keep the length to
+one line for displaying during searches. These four variables are required in
+every PKGBUILD. \fIurl\fR is also highly recommended so users can find more
+information on the package if needed.
+
+\fIdepends\fR and \fImakedepends\fR are bash arrays which define the
+dependencies of the package. Packages listed in \fImakedepends\fR are required
+only for building the package, and not for runtime. \fIdepends\fR is used to
+list runtime depends. To build the package using \fBmakepkg\fR, ALL dependencies
+must be satisfied. For \fBpacman\fR to install the package, all runtime depends
+must be satisfied.
+
+The \fIbackup\fR array specifies files that should be treated specially
+when removing or upgrading packages. See \fBHANDLING CONFIG FILES\fR in
+the \fIpacman\fR manpage for more information on this.
+
+The \fIsource()\fR array tells makepkg which files to download or extract before
+compiling begins. The \fImd5sums()\fR array provides md5sums for each of these
+files. These are used to validate the integrity of the source files.
+
+The \fIbuild\fR function is what actually does the work of putting the package
+together. Sometimes this is as simple as a configure, make, make install (to
+$startdir/pkg). However, some customizations are often needed during the build
+process.
+
+Once your PKGBUILD is created, you can run \fBmakepkg\fR from the build
+directory. \fBmakepkg\fR will check dependencies and look for the source files
+required to build. If some are missing it will attempt to download them,
+provided there is a fully-qualified URL in the \fIsource()\fR array.
+
+.SS Install/Upgrade/Remove Scripting
+Pacman has the ability to store and execute a package-specific script when it
+installs, removes, or upgrades a package. This allows a package to "configure
+itself" after installation and do the opposite right before it is removed.
+
+The exact time the script is run varies with each operation:
+
+.TP
+.B pre_install
+script is run right before files are extracted.
+
+.TP
+.B post_install
+script is run right after files are extracted.
+
+.TP
+.B pre_upgrade
+script is run right before files are extracted.
+
+.TP
+.B post_upgrade
+script is run after files are extracted.
+
+.TP
+.B pre_remove
+script is run right before files are removed.
+
+.TP
+.B post_remove
+script is run right after files are removed.
+
+.P
+To use this feature, just create a file (eg, pkgname.install) and put it in
+the same directory as the PKGBUILD script. Then use the \fIinstall\fR
+directive:
+
+install=pkgname.install
+
+The install script does not need to be specified in the \fIsource\fR array.
+A template install file is available in your ABS tree (/var/abs/install.proto).
+
+.SH OPTIONS AND DIRECTIVES
+.TP
+.B pkgname
+The name of the package. This has be a unix-friendly name as it will be
+used in the package filename.
+
+.TP
+.B pkgver
+This is the version of the software as released from the author (eg, 2.7.1).
+
+.TP
+.B pkgrel
+This is the release number specific to \*(DS's release. This allows package
+maintainers to make updates to the package's configure flags, for example.
+
+.TP
+.B pkgdesc
+This should be a brief description of the package and its functionality.
+
+." Is this applicable below?
+.TP
+.B pkgdesc_localized \fI(array)\fR
+Array of the localized package descriptions. The format is the following:
+pkgdesc_localized=('xx_YY foo' 'xx_YY bar')
+
+.TP
+.B url
+This field contains an optional URL that is associated with the piece of
+software being packaged. This is typically the project's website.
+
+.TP
+.B license \fI(array)\fR
+This field specifies the license(s) that apply to the package. Commonly-used
+licenses are typically found in \fI/usr/share/licenses/common\fR. If you
+see the package's license there, simply reference it in the license field
+(eg, \fBlicense="GPL"\fR). If the package provides a license not found in
+\fI/usr/share/licenses/common\fR, then you should include the license in
+the package itself and set \fBlicense="custom"\fR or
+\fBlicense="custom:LicenseName"\fR. The license itself should be placed in a
+directory called \fI$startdir/pkg/usr/share/licenses/$pkgname\fR. If multiple
+licenses are applied, use the array form: \fBlicenses=('GPL' 'FDL')\fR
+
+.TP
+.B install
+Specifies a special install script that is to be included in the package.
+This file should reside in the same directory as the PKGBUILD, and will be
+copied into the package by makepkg. It does not need to be included in the
+\fIsource\fR array. (eg, install=pkgname.install)
+
+." Is this applicable below?
+.TP
+.B up2date
+This directive should contain a command that prints the current upstream stable
+version of the project.
+
+.TP
+.B source \fI(array)\fR
+The \fIsource\fR line is an array of source files required to build the
+package. Source files must reside in the same directory as the PKGBUILD
+file, unless they have a fully-qualified URL.
+
+.TP
+.B md5sums \fI(array)\fR
+If this field is present, it should contain an MD5 hash for every source file
+specified in the \fIsource\fR array (in the same order). \fImakepkg\fR will use
+this to verify source file integrity during subsequent builds. To easily
+generate md5sums, first build using the PKGBUILD then run
+\fBmakepkg -g >>PKGBUILD\fR. Then you can edit the PKGBUILD and move the
+\fImd5sums\fR line from the bottom to an appropriate location.
+
+." Is this applicable below?
+.TP
+.B signatures \fI(array)\fR
+If this field is present, it should contain an array of gpg signatures required
+to validate the source files. Where there is no signature available just leave
+it empty, like:
+
+signatures=(${source[0]}.asc '')
+
+.TP
+.B groups \fI(array)\fR
+This is an array of symbolic names that represent groups of packages, allowing
+you to install multiple packages by requesting a single target. For example,
+one could install all KDE packages by installing the 'kde' group.
+
+.TP
+.B archs \fI(array)\fR
+This array defines on which architectures the given package is available.
+
+.TP
+.B backup \fI(array)\fR
+A space-delimited array of filenames (without a preceding slash). The
+\fIbackup\fR line will be propagated to the package meta-info file for
+pacman. This will designate all files listed there to be backed up if this
+package is ever removed from a system. See \fBHANDLING CONFIG FILES\fR in
+the \fIpacman\fR manpage for more information.
+
+.TP
+.B depends \fI(array)\fR
+An array of packages that this package depends on to build and run. Packages
+in this list should be surrounded with single quotes and contain at least the
+package name. They can also include a version requirement of the form
+\fBname<>version\fR, where <> is one of these three comparisons:
+\fB>=\fR (greater than equal to), \fB<=\fR (less than or equal to), or
+\fB=\fR (equal to).
+
+.TP
+.B makedepends \fI(array)\fR
+An array of packages that this package depends on to build, but not at runtime.
+Packages in this list should follow the same format as \fIdepends\fR.
+
+.TP
+.B conflicts \fI(array)\fR
+An array of packages that will conflict with this package (ie, they cannot both
+be installed at the same time). This directive follows the same format as
+\fIdepends\fR except you cannot specify versions.
+
+.TP
+.B provides \fI(array)\fR
+An array of "virtual provisions" that this package provides. This allows a
+package to provide dependencies other than its own package name. For example,
+the kernel26beyond package can each provide 'kernel26' which allows packages
+to simply depend on 'kernel26' rather than "kernel26 OR kernel26beyond".
+
+.TP
+.B replaces \fI(array)\fR
+This is an array of packages that this package should replace, and can be used
+to handle renamed/combined packages. For example, if the j2re package gets
+renamed to jre, then subsequent 'pacman -Syu' calls will not pick up the
+upgrade, due to the differing package names. \fIreplaces\fR handles this.
+
+.TP
+.B options \fI(array)\fR
+This array allows you to override some of makepkg's default behaviour
+when building packages. To set an option, just include the option name
+in the \fBoptions\fR array.
+.RS
+.TP
+.B nostrip
+don't strip binaries/libraries.
+.TP
+.B keepdocs
+keep /usr/share/doc and /usr/share/info directories.
+.TP
+.B force
+force the package to be upgraded by --sysupgrade, even if it's an older version.
+.RE

-# optimization OK
-.fi
-.RE
-
-As you can see, the setup is fairly simple. The first line tracks the time of
-the last update, this is automatically updated after a successful build.
-
-The next line defines its build time. Of course, it depends on your hardware,
-so we use SBUs instead of minutes as a unit.
-
-SBU is the Static Binutils Unit, which means the time "repoman merge binutils"
-takes on your machine. By default makepkg will print out how many seconds the
-build took. After you built binutils, you should update your /etc/makepkg.conf:
-
-SBU="257"
-
-The line above means compiling binutils on your machine took 257 seconds.
-Starting from this point, makepkg will print out SBUs instead of seconds after
-successful builds, and this SBU value will be equal on anyone's machine.
-
-If you wish to maintain the package, write your name or nick and e-mail
-address to the third line. If you don't plan to maintain the package just wrote
-the PKGBUILD, then write Contributor instead of Maintainer, and then someone
-can take it and will add his/her line later. Other lines like "Modified by" are
-not allowed. Use the darcs patch comments to mention others if you wish.
-
-pkgname defines the package name. It should not contain any uppercase letters.
-The package version defines the upstream version, while the package release
-tracks the Archlinux-specific changes. pkgrel should be an integer, pkgrels
-like 5wanda1 are reserved for security updates. There the rule is the
-following: If the original package's pkgrel was 4, then increment it once when
-you add a security patch, but then use 5wanda1, 5wanda2 and so on. This way
-the user can easily upgrade to pkgrel=5 which is in -current.
-
-pkgdesc is a short one-line description for the package. Usually taken from
-the project's homepage or manpage. Try to keep the lenght under 80 chars.
-
-depends() is a bash array which defines the dependencies of the package.
-depends() means the other package is required for building and using the
-current one. If the dependency is runtime-only, then use rodepends(), if
-buildtime-only then use makedepends().
-
-The next line is a special Finclude commands which allows you to inherit
-any directive from a PKGBUILD scheme. They can be found in the FST,
-under /source/include. The "util" scheme always included, since its
-provided functions are used by almost every PKGBUILD. Look at the
-/source/include/sourceforge.sh, it provides the url, up2date and source()
-directives, so we don't have to specify them here. After the Finclude you
-can overwrite the inherited directives, for example define a custom up2date
-if the inherited one is not sutable for you.
-
-The groups() array's first element can't be omitted, and it should be a valid
-"first group". This means it should be in a foo or foo-extra format, where foo
-or foo-extra is a dir under /source in the FST.
-
-The archs() array defines for which architectures the given package is
-available. If it's not available, it means that gensync will skip it when
-generating package databases. If you are not able to provide a binary package
-for a given arch, don't include that in archs()! For example, no matter if
-the package could be compiled in x86_64, if you haven't compiled it yourself,
-don't include it. If you're sure it won't be available on a given arch (for
-example it's written in x86 asm), then use !arch, for example !x86_64.
-
-The sha1sums() array can be generated with the makepkg -g command. Its purpose
-is to prevent compiling from wrong sources, especially when the build is
-automatic. Where it is available you can use signatures(), its goal is that
-you don't have to update it manually every time.
-
-The last line will be added automatically to the end of the PKGBUILD if the
-build() function used your $CFLAGS or $CXXFLAGS. This is handy if you want to
-cross-compile on a faster machine for a slower architecture. Until the package
-doesn't use our $CFLAGS we can't cross-compile it, so please try to avoid
-creating "unoptimized" packages. If the package doesn't contain any
-architecture-dependent file, then you can add this line manually as makepkg
-will not detect this.
-
-Finally we define a build() function that will build the package. If you don't
-want to do anything special, probably you don't have to specify anything, as
-the default build() (inherited from util.sh) will fit your needs. Even if you
-define a custom build(), probably you can re-use parts of the default build().
-For the list of special functions provided by util.sh and others refer to
-the /source/include dir. Again, util.sh is included automatically, but you
-have to Finclude the others before using them!
-
-Once the package is successfully installed into the package root, \fImakepkg\fP
-will prepare some documentation. It will
-then strip debugging info from libraries and binaries and generate a meta-info
-file. Finally, it will compress everything into a .fpm file and leave it
-in the directory you ran \fBmakepkg\fP from.
-
-At this point you should have a package file in the current directory, named
-something like name-version-release-arch.fpm. Done!
-
-.SH Install/Upgrade/Remove Scripting
-Pacman has the ability to store and execute a package-specific script when it
-installs, removes, or upgrades a package. This allows a package to "configure
-itself" after installation and do the opposite right before it is removed.
-
-The exact time the script is run varies with each operation:
-.TP
-.B pre_install
-script is run right before files are extracted.
-
-.TP
-.B post_install
-script is run right after files are extracted.
-

-.B pre_upgrade
-script is run right before files are extracted.

-.B post_upgrade
-script is run after files are extracted.
-
-.TP
-.B pre_remove
-script is run right before files are removed.
-
-.TP
-.B post_remove

-
-.RE
-To use this feature, just create a file (eg, pkgname.install) and put it in
-the same directory as the PKGBUILD script. Then use the \fIinstall\fP directive:
-.RS
-.nf
-install=pkgname.install
-.fi
-.RE
-
-The install script does not need to be specified in the \fIsource\fP array.
-If you omit the install directive then makepkg will check for the
-$pkgname.install install and will use it if it's present.
-
-You can find a scriptlet skeleton in the /docs/tech/skel/ directory, use it
-when creating new packages.
-
-The scriptlet messages are parsed, a simple example tells you everything:
-.nf
-post_upgrade()
-{
- echo "START this will be good"
- echo "DONE 0"
- echo "START this will fail"
- echo "DONE 1"
- echo "old message"

-option is still in development and may change in the future)
-
-.TP
-.B install
-Specifies a special install script that is to be included in the package.

-\fIsource\fP array. (eg, install=modutils.install)
-
-.TP
-.B up2date

-
-.TP
-.B source \fI(array)\fP
-The \fIsource\fP line is an array of source files required to build the
-package. Source files must reside in the same directory as the PKGBUILD
-file, unless they have a fully-qualified URL. Then if the source file
-does not already exist in /var/cache/pacman/src, the file is downloaded

-
-.TP
-.B md5sums \fI(array)\fP
-If this field is present, it should contain an MD5 hash for every source file
-specified in the \fIsource\fP array (in the same order). makepkg will use

-one could install all KDE packages by installing the 'kde' group.
-
-.TP
-.B archs \fI(array)\fP
-This array defines on which architectures the given package is avalibable.
-If it's not available, that will mean that gensync will skip it when generating
-package databases.
-
-.TP
-.B backup \fI(array)\fP
-A space-delimited array of filenames (without a preceding slash). The
-\fIbackup\fP line will be propagated to the package meta-info file for
-pacman. This will designate all files listed there to be backed up if this
-package is ever removed from a system. See \fBHANDLING CONFIG FILES\fP in
-the \fIpacman\fP manpage for more information.
-
-.TP
-.B depends \fI(array)\fP
-An array of packages that this package depends on to build and run. Packages
-in this list should be surrounded with single quotes and contain at least the
-package name. They can also include a version requirement of the form
-\fBname<>version\fP, where <> is one of these three comparisons: \fB>=\fP
-(greater than equal to), \fB<=\fP (less than or equal to), or \fB=\fP (equal to).
-See the PKGBUILD example above for an example of the \fIdepends\fP directive.
-
-.TP
-.B makedepends \fI(array)\fP
-An array of packages that this package depends on to build (ie, not required
-to run). Packages in this list should follow the same format as \fIdepends\fP.
-
-.TP
-.B rodepends \fI(array)\fP
-An array of packages that this package depends on to run (ie, not required to
-build). Generally \fIrodepends\fP should be avoided in favour of \fIdepends\fP
-except where this will create circular dependency chains. (For example building
-logrotate doesn't requires to have dcron installed.) Packages in this list
-should follow the same format as \fIdepends\fP.
-
-.TP
-.B conflicts \fI(array)\fP
-An array of packages that will conflict with this package (ie, they cannot both
-be installed at the same time). This directive follows the same format as
-\fIdepends\fP except you cannot specify versions here, only package names.
-
-.TP
-.B provides \fI(array)\fP
-An array of "virtual provisions" that this package provides. This allows a package
-to provide dependency names other than it's own package name. For example, the
-kernel-scsi and kernel-ide packages can each provide 'kernel' which allows packages
-to simply depend on 'kernel' rather than "kernel-scsi OR kernel-ide OR ..."
-
-.TP
-.B replaces \fI(array)\fP
-This is an array of packages that this package should replace, and can be used to handle
-renamed/combined packages. For example, if the kernel package gets renamed
-to kernel-ide, then subsequent 'pacman -Syu' calls will not pick up the upgrade, due
-to the differing package names. \fIreplaces\fP handles this.
-
-.TP
-.B options \fI(array)\fP
-This is an array of various boolean options. The possible values are:
-.nf
-nodocs Don't add any documentation automatically (ie. when there'll be
- a separate documentation subpackage).
-nostrip Don't strip binaries/libraries.
-force This is used to force the package to be upgraded by --sysupgrade,
- even if its an older version.
-nobuild If this directive set, gensync will ignore this package, so users
- must build these packages on their machines, they will not be able
- to install them with pacman -S. Useful for closed-source, but
- freeware programs.
-nofakeroot Don't drop privileges after chrooting. Required by some broken
- packages.
-scriptlet Don't skip executing scriptlets even if we're in chroot.

-.SH What is the process of chrooted build ?
-
-First, what is chroot? We currently use fakeroot to prevent build() from
-modifying the host system, and we use a prefix or DESTDIR directive to install
-everything to a directory and not under to the host system. This is good, but
-not enough.
-
-This system lacks of the ability to control the list of installed packages
-during the build on the system of a packager, the given compiled package maybe
-linked itself to an extra installed library. This way we can't really control
-the list of real dependencies. For example if libquicktime is installed from
-source on my system, then mplayer or any other program can link itself to that,
-and so that depends() will be incorrect. Or if I have the closed source binary
-NVidia drivers installed, some programs link tho NVidia's libraries.
-
-Of course there is a sollution to avoid this, to use a real chroot instead of a
-simple fakeroot. What is this means? The followings:
-
-When starting the build, a core chroot system is installed under /var/chroot.
-(Of course you can change this value under /etc/makepkg.conf.) The core system
-contains ~60 packages which are must installed to build any package in
-a chrooted environment. These packages (for example gcc, kernel-headers, make)
-should not be mentioned in makedepends(). 'pacman -Sg core chroot-core
-devel-core' should show you the actial list. (We try to change this list rarely
-of course.)
-
-When you start building with makepkg -R, pacman will install these packages to
-/var/chroot if necessary. This will produce a fully "clean" Archlinux system,
-that consits of base packages only. This /var/chroot is fully separated from
-the host system so that this will solve the problems mentioned above.
-(Linking to a library installed from source, etc.)
-
-Here comes the fun part. The packages listed in depends() and makedepends() are
-installed to this clean (/var/chroot) system. From this point, this chroot is
-capable to build the specified package in it without any unnecessary package
-installed, fully separated from the host system.
-
-After this the chroot should be cleaned up which means the removal of the
-installed depends() and makedepends(). This ensures us not to build from
-scratch the core chroot.
-
-This way we can prevent lots of dependency problems and it is even possible to
-build packages for a different Archlinux version. This is quite efficent when
-building security updates or fixing critical bugs in the -stable tree.
-
-If the build is failed, the working directory will not be deleted, you can find
-it under /var/chroot/var/tmp/fst. Later if you want to clean your chroot
-(delete the working directory and remove unnecessary packages) you can use 'makepkg -CR'.
-
-To activate building in a chroot, you should run makepkg as root at least with
-the -R option.
-
-.SH Package splitting
-
-Package splitting means moving out a list of specifed files to subpackages (like
-libmysql out of mysql) and then defining the properties of subpackages.
-
-NOTE: if you create several subpackages, maintaining those packages will
-require more and more time. Thus, unnecessary splits aren't welcome.
-Especially, if you split out a library, then don't move the headers to the
-package just to speed up building with a few seconds!
-
-The \fBsubpkgs()\fP array is to define the pkgnames of the subpackages. From
-now all the directives has their subfoo equivalent:
-.nf
-pkgname -> subpkgs()
-pkgdesc -> subdescs()
-pkgdesc_localized -> subdescs_localized()
-license() -> sublicense()
-replaces() -> subreplaces()
-groups() -> subgroups()
-depends() -> subdepends()
-rodepends() -> subrodepends()
-removes() -> subremoves()
-conflicts() -> subconflicts()
-provides() -> subprovides()
-backup() -> subbackup()
-install -> subinstall()
-options -> suboptions()
-archs -> subarchs()
-.fi
-
-Also note that bash does not support two-dimensional arrays, so when defining the
-array of arrays, then quotes are the major separators and spaces are the minor ones.
-
-Simple example:
-.nf
-Add the followings to your bottom of your PKGBUILD
-subpkgs=('foo' 'bar')
-subdescs=('desc of foo' 'desc of bar')
-subdepends=('foodep1 foodep2' 'bardep1 bardep2')
-subgroups=('apps' 'apps')
-subarchs=('i686 x86_64' 'i686 x86_64')
-.fi
-
-You may define conflicts, replaces and other directives for your subpackages, but
-the requirement is only to define these 5 ones.
-
-The second part is to move some files to the - just defined - subpackages. You
-should use the Fsplit command for this at the end of your build() function. You
-can read more about Fsplit in the fwmakepkg documentation, but here is a short
-example:
-.nf
-
-Fsplit subpkgname usr/share/
-
-.fi
-This will move the /usr/share dir of the package to the "subpkgname" subpackage.
-
-NOTE: never use a trailing slash when defining file patterns, especially if you
-use wildcards in it!
