This article contains an exhaustive manual of how to create new source
packages for XBPS, the package manager of the *Void Linux distribution*.
Introduction
------------
The `xbps-packages` repository contains all `source` packages that are the
recipes to download, compile and build binary packages for `Void`.
Those `source` package files are called `templates`.
2013-11-22 17:51:38 +01:00
The `template files` are `GNU bash` shell scripts that must define some required/optional
`variables` and `functions` that are processed by `xbps-src` (the package builder)
to generate the resulting binary packages.
A simple `template` example is as follows:
2013-11-22 17:51:38 +01:00
--------------------------------------------------------------------------
# Template file for 'foo'
## source section
pkgname="foo"
version="1.0"
revision="1"
build_style="gnu-configure"
short_desc="A short description max 72 chars"
maintainer="name <email>"
license="GPL-3"
homepage="http://www.foo.org"
distfiles="http://www.foo.org/foo-${version}.tar.gz"
checksum="fea0a94d4b605894f3e2d5572e3f96e4413bcad3a085aae7367c2cf07908b2ff"
## package section
foo_package() {
pkg_install() {
vmove all
}
2013-11-22 17:51:38 +01:00
}
---------------------------------------------------------------------------
There are two main `sections` in a template: the `source section` and the
`package section`. The `source section` contains definitions to download, build
and install the package files to a `fake destdir`. The `package section`
contains the definitions to how the resulting binary packages are generated.
A template always requires at least a `source section` and a `package section`;
multiple `package sections` can be defined to generate `multiple binary packages`.
Don't worry if anything is not clear as it should be. The reserved `variables`
and `functions` will be explained later. This `template` file should be created
in a directory matching `$pkgname`, i.e: `xbps-packages/srcpkgs/foo/template`.
If everything went fine after running `xbps-src build-pkg` a binary package
called `foo-1.0_1.<arch>.xbps` will be generated in the local repository.
Additional binary packages (those defined in `_package() blocks` need a
symlink to the `main` package, like this:
----------------------------------
/srcpkgs
|- foo <- directory
| |- template
|- foo-devel <- symlink to `foo`
----------------------------------
Otherwise dependencies requiring those packages won't find its `template`
file.
Package build phases
--------------------
Building a package consist of the following phases:
2013-11-22 17:51:38 +01:00
*fetch*::
This phase downloads required sources for a `source package`, as defined by
the `distfiles` variable or `do_fetch()` function.
2013-11-22 17:51:38 +01:00
*extract*::
This phase extracts the `distfiles` files into `$wrksrc` or executes the `do_extract()`
function, which is the directory to be used to compile the `source package`.
2013-11-22 17:51:38 +01:00
*configure*::
This phase executes the `configuration` of a `source package`, i.e `GNU configure scripts`.
2013-11-22 17:51:38 +01:00
*build*::
This phase compiles/prepares the `source files` via `make` or any other compatible method.
2013-11-22 17:51:38 +01:00
*install-destdir*::
This phase installs the `package files` into a `fake destdir`, via `make install` or
any other compatible method.
2013-11-22 17:51:38 +01:00
*build-pkg*::
This phase builds the `binary packages` with files stored in the `package destdir`.
`xbps-src` supports running just the specified phase, and if it ran
successfully, the phase will be skipped later (unless its work directory
`${wrksrc}` is removed with `xbps-src clean`).
Global functions
----------------
The following functions are defined by `xbps-src` and can be used on any template:
*vinstall()*::
`vinstall <file> <mode> <targetdir> [<name>]`
Installs `file` with the specified `mode` into `targetdir` in `$DESTDIR`
(if called from a `source section`) or `$PKGDESTDIR` (if called from a `package section`).
The optional 4th argument can be used to change the `file name`.
*vcopy()*::
`vcopy <pattern> <targetdir>`
Copies resursively all files in `pattern` to `targetdir` on `$DESTDIR`
(if called from a `source section`) or `$PKGDESTDIR` (if called from a `package section`).
*vmove()*::
`vmove <pattern>`
Moves `pattern` to the specified directory in `$DESTDIR`
(if called from a `source section`) or `$PKGDESTDIR` (if called from a `package section`).
*vmkdir()*::
`vmkdir <directory> [<mode>]`
Creates a directory in `$DESTDIR` (if called from a `source section`) or
$PKGDESTDIR` (if called from a `package section`). The 2nd optional argument
sets the mode of the directory.
NOTE: shell wildcards must be properly quoted.
