PKGBUILD(5)
===========
Name
----
PKGBUILD - Arch Linux package build description file
Synopsis
--------
PKGBUILD
Description
-----------
This manual page describes general rules about PKGBUILDs. Once a
PKGBUILD is written, the actual package is built using makepkg and installed
with pacman.
NOTE: An example PKGBUILD, useful for reference, is located in '{pkgdatadir}'
along with other example files such as a ChangeLog and an install
script. You can copy the provided PKGBUILD.proto file to a new package build
directory and make customizations to suit your needs.
Options and Directives
----------------------
The following is a list of standard options and directives available for use
in a PKGBUILD. These are all understood and interpreted by makepkg, and most
of them will be directly transferred to the built package.
If you need to create any custom variables for use in your build process, it is
recommended to prefix their name with an '_' (underscore).
This will prevent any possible name clashes with internal makepkg variables.
For example, to store the base kernel version in a variable, use something
similar to `$_basekernver`.
*pkgname (array)*::
Either the name of the package or an array of names for split packages.
Because it will be used in the package filename, this has to be unix-friendly.
Members of the array are not allowed to start with hyphens.
*pkgver*::
The version of the software as released from the author (e.g., '2.7.1').
The variable is not allowed to contain colons or hyphens.
*pkgrel*::
This is the release number specific to the Arch Linux release. This
allows package maintainers to make updates to the package's configure
flags, for example. This is typically set to '1' for each new upstream
software release and incremented for intermediate PKGBUILD updates. The
variable is not allowed to contain hyphens.
*pkgdesc*::
This should be a brief description of the package and its functionality.
Try to keep the description to one line of text and not use the package's name.
*epoch*::
Used to force the package to be seen as newer than any previous versions
with a lower epoch, even if the version number would normally not trigger
such an upgrade. This value is required to be a positive integer; the
default value if left unspecified is '0'. This is useful when the version
numbering scheme of a package changes (or is alphanumeric), breaking normal
version comparison logic. See linkman:pacman[8] for more information on
version comparisons.
*url*::
This field contains a URL that is associated with the software being
packaged. Typically the project's website.
*license (array)*::
This field specifies the license(s) that apply to the package.
Commonly used licenses can be found in '/usr/share/licenses/common'. If you
see the package's license there, simply reference it in the license
field (e.g., `license=('GPL')`). If the package provides a license not
available in '/usr/share/licenses/common', then you should include it
in the package itself and set `license=('custom')` or
`license=('custom:LicenseName')`. The license should be placed in
'$pkgdir/usr/share/licenses/$pkgname/' when building the package. If
multiple licenses are applicable, list all of them:
`license=('GPL' 'FDL')`.
*install*::
Specifies a special install script that is to be included in the package.
This file should reside in the same directory as the PKGBUILD, and will
be copied into the package by makepkg. It does not need to be included
in the source array (e.g., `install=$pkgname.install`).
*changelog*::
Specifies a changelog file 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 source array (e.g., `changelog=$pkgname.changelog`).
*source (array)*::
An array of source files required to build the package. Source files
must either reside in the same directory as the PKGBUILD, or be a
fully-qualified URL that makepkg can use to download the file.
To make the PKGBUILD as useful as possible, use the `$pkgname` and `$pkgver`
variables if possible when specifying the download location. Compressed files
will be extracted automatically unless found in
the noextract array described below.
+
It is also possible to change the name of the downloaded file, which is helpful
with weird URLs and for handling multiple source files with the same
name. The syntax is: `source=('filename::url')`.
+
Files in the source array with extensions `.sig` or `.asc` are recognized by
makepkg as PGP signatures and will be automatically used to verify the integrity
of the corresponding source file.
*noextract (array)*::
An array of filenames corresponding to those from the source array. Files
listed here will not be extracted with the rest of the source files. This
is useful for packages that use compressed data directly.
*md5sums (array)*::
This array contains an MD5 hash for every source file specified in the
source array (in the same order). makepkg will use this to verify source
file integrity during subsequent builds. To easily generate md5sums, run
`makepkg -g >> PKGBUILD`. If desired, move the md5sums line to an
appropriate location.
*sha1sums, sha256sums, sha384sums, sha512sums (arrays)*::
Alternative integrity checks that makepkg supports; these all behave
similar to the md5sums option described above. To enable use and generation
of these checksums, be sure to set up the `INTEGRITY_CHECK` option in
linkman:makepkg.conf[5].
*groups (array)*::
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.
*arch (array)*::
Defines on which architectures the given package is available (e.g.,
`arch=('i686' 'x86_64')`). Packages that contain no architecture specific
files should use `arch=('any')`.
*backup (array)*::
An array of filenames, without preceding slashes, that
should be backed up if the package is removed or upgraded. This is
commonly used for packages placing configuration files in /etc. See
Handling Config Files in linkman:pacman[8] for more information.
*depends (array)*::
An array of packages this package depends on to run. Entries in
this list should be surrounded with single quotes and contain at least
the package name. Entries can also include a version requirement of the
form 'name<>version', where `<>` is one of five comparisons: `>=` (greater
than or equal to), `<=` (less than or equal to), `=` (equal to), `>`
(greater than), or `<` (less than).
+
If the dependency name appears to be a library (ends with .so), makepkg will
try to find a binary that depends on the library in the built package and
append the version needed by the binary. Appending the version yourself
disables auto detection.
*makedepends (array)*::
An array of packages this package depends on to build but are not
needed at runtime. Packages in this list follow the same format as
depends.
*checkdepends (array)*::
An array of packages this package depends on to run its test suite
but are not needed at runtime. Packages in this list follow the same
format as depends. These dependencies are only considered when the
check() function is present and is to be run by makepkg.
*optdepends (array)*::
An array of packages (and accompanying reasons) that are not essential for
base functionality, but may be necessary to make full use of the contents
of this package. optdepends are currently for informational purposes only
and are not utilized by pacman during dependency resolution. The format
for specifying optdepends is:
optdepends=('fakeroot: for makepkg usage as normal user')
*conflicts (array)*::
An array of packages that will conflict with this package (i.e. they
cannot both be installed at the same time). This directive follows the
same format as depends. Versioned conflicts are supported using the
operators as described in `depends`.
*provides (array)*::
An array of ``virtual provisions'' this package provides. This allows
a package to provide dependencies other than its own package name. For
example, the dcron package can provide 'cron', which allows packages to
depend on 'cron' rather than 'dcron OR fcron'.
+
Versioned provisions are also possible, in the 'name=version' format. For
example, dcron can provide 'cron=2.0' to satisfy the 'cron>=2.0' dependency of
other packages. Provisions involving the `>` and `<` operators are invalid as
only specific versions of a package may be provided.
+
If the provision name appears to be a library (ends with .so), makepkg will
try to find the library in the built package and append the correct
version. Appending the version yourself disables auto detection.
*replaces (array)*::
An array of packages this package should replace. This can be used
to handle renamed/combined packages. For example, if the 'j2re' package
is renamed to 'jre', this directive allows future upgrades to continue
as expected even though the package has moved. Versioned replaces are
supported using the operators as described in `depends`.
+
Sysupgrade is currently the only pacman operation that utilizes this field.
A normal sync or upgrade will not use its value.
*options (array)*::
This array allows you to override some of makepkg's default behavior
when building packages. To set an option, just include the option name
in the options array. To reverse the default behavior, place an ``!'' at
the front of the option. Only specify the options you specifically want
to override, the rest will be taken from linkman:makepkg.conf[5].
*NOTE:* 'force' is a now-removed option in favor of the top level 'epoch'
variable.
*strip*;;
Strip symbols from binaries and libraries. If you frequently
use a debugger on programs or libraries, it may be helpful to
disable this option.
*docs*;;
Save doc directories. If you wish to delete doc directories,
specify `!docs` in the array.
*libtool*;;
Leave libtool (.la) files in packages. Specify `!libtool` to
remove them.
*emptydirs*;;
Leave empty directories in packages.
*zipman*;;
Compress man and info pages with gzip.
*upx*;;
Compress binary executable files using UPX.
*ccache*;;
Allow the use of ccache during build. More useful in its negative
form `!ccache` with select packages that have problems building
with ccache.
*distcc*;;
