This repository contains the XBPS source packages collection to build binary packages for the Void Linux distribution.
xbps-src script will fetch and compile the sources, and install its
files into a
fake destdir to generate XBPS binary packages that can be installed
or queried through the
xbps-query(1) utilities, respectively.
xbps-src requires an utility to chroot and bind mount existing directories
masterdir that is used as its main
multiple utilities to accomplish this task:
xbps-uunshare(1)- XBPS utility that uses
user_namespaces(7)(part of xbps, default).
xbps-uchroot(1)- XBPS utility that uses
namespacesand must be
setgid(part of xbps).
proot(1)- utility that implements chroot/bind mounts in user space, see https://proot-me.github.io/.
NOTE: you don't need to be
xbps-src, use your preferred chroot style as explained below.
This utility requires these Linux kernel options:
This is the default method, and if your system does not support any of the required kernel
options it will fail with
EINVAL (Invalid argument).
This utility requires these Linux kernel options:
Your user must be added to a special group to be able to use
xbps-uchroot(1) and the
executable must be
# chown root:<group> xbps-uchroot # chmod 4750 xbps-uchroot # usermod -a -G <group> <user>
NOTE: by default in void you shouldn't do this manually, your user must be a member of the
To enable it:
$ cd void-packages $ echo XBPS_CHROOT_CMD=uchroot >> etc/conf
If for some reason it's erroring out as
ERROR clone (Operation not permitted), check that
your user is a member of the required
group and that
xbps-uchroot(1) utility has the
proper permissions and owner/group as explained above.
proot(1) utility implements chroot and bind mounts support completely in user space,
and can be used if your Linux kernel does not have support for namespaces. See https://proot-me.github.io/.
for more information.
To enable it:
$ cd void-packages $ echo XBPS_CHROOT_CMD=proot >> etc/conf
void-packages git repository, install the bootstrap packages:
$ git clone git://github.com/void-linux/void-packages.git $ cd void-packages $ ./xbps-src binary-bootstrap
$ ./xbps-src -h
to see all available targets/options and start building any available package
bootstrap packages are a set of packages required to build any available source package in a container. There are two methods to install the
bootstrap: all bootstrap packages will be built from scratch; additional utilities are required in the
host system to allow building the
base-chroot package: binutils, gcc, perl, texinfo, etc.
binary-bootstrap: the bootstrap binary packages are downloaded via XBPS repositories.
If you don't want to waste your time building everything from scratch probably it's better to use
etc/defaults.conf file contains the possible settings that can be overridden
etc/conf configuration file for the
xbps-src utility; if that file
does not exist, will try to read configuration settings from
If you want to customize default
LDFLAGS, don't override
those defined in
etc/defaults.conf, set them on
etc/conf instead i.e:
$ echo 'XBPS_CFLAGS="your flags here"' >> etc/conf $ echo 'XBPS_LDFLAGS="your flags here"' >> etc/conf
Native and cross compiler/linker flags are set per architecture in
common/cross-profiles respectively. Ideally those settings are good enough by default,
and there's no need to set your own unless you know what you are doing.
etc/defaults.virtual file contains the default replacements for virtual packages,
used as dependencies in the source packages tree.
If you want to customize those replacements, copy
and edit it accordingly to your needs.
The following directory hierarchy is used with a default configuration file:
/void-packages |- common |- etc |- srcpkgs | |- xbps | |- template | |- hostdir | |- binpkgs ... | |- ccache-<arch> ... | |- distcc-<arch> ... | |- repocache ... | |- sources ... | |- masterdir | |- builddir -> ... | |- destdir -> ... | |- host -> bind mounted from <hostdir> | |- void-packages -> bind mounted from <void-packages>
The description of these directories is as follows:
masterdir: master directory to be used as rootfs to build/install packages.
builddir: to unpack package source tarballs and where packages are built.
destdir: to install packages, aka fake destdir.
hostdir/ccache: to store ccache data if the
XBPS_CCACHEoption is enabled.
hostdir/distcc-<arch>: to store distcc data if the
XBPS_DISTCCoption is enabled.
hostdir/repocache: to store binary packages from remote repositories.
hostdir/sources: to store package sources.
hostdir/binpkgs: local repository to store generated binary packages.
The simplest form of building package is accomplished by running the
pkg target in
$ cd void-packages $ ./xbps-src pkg <pkgname>
When the package and its required dependencies are built, the binary packages will be created
and registered in the default local repository at
hostdir/binpkgs; the path to this local repository can be added to
any xbps configuration file (see xbps.d(5)) or by explicitly appending them via cmdline, i.e:
$ xbps-install --repository=hostdir/binpkgs ... $ xbps-query --repository=hostdir/binpkgs ...
By default xbps-src will try to resolve package dependencies in this order:
It is possible to avoid using remote repositories completely by using the
The default local repository may contain multiple sub-repositories:
The supported build options for a source package can be shown with
$ ./xbps-src show-options foo
Build options can be enabled with the
-o flag of
$ ./xbps-src -o option,option1 pkg foo
Build options can be disabled by prefixing them with
$ ./xbps-src -o ~option,~option1 pkg foo
Both ways can be used together to enable and/or disable multiple options
at the same time with
$ ./xbps-src -o option,~option1,~option2 pkg foo
The build options can also be shown for binary packages via
$ xbps-query -R --property=build-options foo
NOTE: if you build a package with a custom option, and that package is available in an official void repository, an update will ignore those options. Put that package on
xbps-pkgdb -m hold footo ignore updates with
xbps-install -u. Once the package is on
hold, the only way to update it is by declaring it explicitly:
xbps-install -u foo.
Permanent global package build options can be set via
XBPS_PKG_OPTIONS variable in the
etc/conf configuration file. Per package build options can be set via
dashes, those should be replaced by
The list of supported package build options and its description is defined in the
common/options.description file or in the
To share a local repository remotely it's mandatory to sign it and the binary packages
stored on it. This is accomplished with the
First a RSA key must be created with
$ openssl genrsa -des3 -out privkey.pem 4096
$ ssh-keygen -t rsa -b 4096 -f privkey.pem
Only RSA keys in PEM format are currently accepted by xbps.
Once the RSA private key is ready you can use it to initialize the repository metadata:
$ xbps-rindex --sign --signedby "I'm Groot" --privkey privkey.pem $PWD/hostdir/binpkgs
And then make a signature per package:
$ xbps-rindex --sign-pkg --privkey privkey.pem $PWD/hostdir/binpkgs/*.xbps
If --privkey is unset, it defaults to
If the RSA key was protected with a passphrase you'll have to type it, or alternatively set
it via the
XBPS_PASSPHRASE environment variable.
Once the binary packages have been signed, check the repository contains the appropriate
$ xbps-query --repository=hostdir/binpkgs -vL ...
Each time a binary package is created, a package signature must be created with
It is not possible to sign a repository with multiple RSA keys.
If for whatever reason a package has been built and it is available in your local repository
and you have to rebuild it without bumping its
revision fields, it is possible
to accomplish this task easily with
$ ./xbps-src -f pkg xbps
Reinstalling this package in your target
rootdir can be easily done too:
$ xbps-install --repository=/path/to/local/repo -yff xbps-0.25_1
Please note that the
package expressionmust be properly defined to explicitly pick up the package from the desired repository.
Setup the slaves (machines that will compile the code):
# xbps-install -Sy distcc
Modify the configuration to allow your local network machines to use distcc (e.g.
# echo "192.168.2.0/24" >> /etc/distcc/clients.allow
Enable and start the
# ln -s /etc/sv/distccd /var/service
Install distcc on the host (machine that executes xbps-src) as well. Unless you want to use the host as slave from other machines, there is no need to modify the configuration.
On the host you can now enable distcc in the
XBPS_DISTCC=yes XBPS_DISTCC_HOSTS="localhost/2 --localslots_cpp=24 192.168.2.101/9 192.168.2.102/2" XBPS_MAKEJOBS=16
The example values assume a localhost CPU with 4 cores of which at most 2 are used for compiler jobs. The number of slots for preprocessor jobs is set to 24 in order to have enough preprocessed data for other CPUs to compile. The slave 192.168.2.101 has a CPU with 8 cores and the /9 for the number of jobs is a saturating choice. The slave 192.168.2.102 is set to run at most 2 compile jobs to keep its load low, even if its CPU has 4 cores. The XBPS_MAKEJOBS setting is increased to 16 to account for the possible parallelism (2 + 9 + 2 + some slack).
In etc/conf you may optionally define a mirror or a list of mirrors to search for distfiles.
$ echo 'XBPS_DISTFILES_MIRROR="ftp://192.168.100.5/gentoo/distfiles"' >> etc/conf
If more than one mirror is to be searched, you can either specify multiple URLs separated with blanks, or add to the variable like this
$ echo 'XBPS_DISTFILES_MIRROR+=" http://repo.voidlinux.de/distfiles"' >> etc/conf
Make sure to put the blank after the first double quote in this case.
The mirrors are searched in order for the distfiles to build a package until the checksum of the downloaded file matches the one specified in the template.
Ultimately, if no mirror carries the distfile, or in case all downloads failed the checksum verification, the original download location is used.
If you use
uchroot for your XBPS_CHROOT_CMD, you may also specify a local path
file:// prefix or simply an absolute path on your build host (e.g. /mnt/distfiles).
Mirror locations specified this way are bind mounted inside the chroot environment
under $XBPS_MASTERDIR and searched for distfiles just the same as remote locations.
xbps-src can cross build packages for some target architectures with a cross compiler.
The supported target is shown with
If a source package has been adapted to be cross buildable
xbps-src will automatically build the binary package(s) with a simple command:
$ ./xbps-src -a <target> pkg <pkgname>
If the build for whatever reason fails, might be a new build issue or simply because it hasn't been adapted to be cross compiled.
xbps-src can be used in any recent Linux distribution matching the CPU architecture.
To use xbps-src in your Linux distribution use the following instructions. Let's start downloading the xbps static binaries:
$ wget http://repo.voidlinux.eu/static/xbps-static-latest.<arch>-musl.tar.xz $ mkdir ~/XBPS $ tar xvf xbps-static-latest.<arch>.tar.xz -C ~/XBPS $ export PATH=~/XBPS/usr/bin:$PATH
If your system does not support
user namespaces, a privileged group is required to be able to use
xbps-uchroot(1) with xbps-src, by default it's set to the
xbuilder group, change this to your desired group:
# chown root:<group> ~/XBPS/usr/bin/xbps-uchroot.static # chmod 4750 ~/XBPS/usr/bin/xbps-uchroot.static
void-packages git repository:
$ git clone git://github.com/void-linux/void-packages
xbps-src should be fully functional; just start the
bootstrap process, i.e:
$ ./xbps-src binary-bootstrap
The default masterdir is created in the current working directory, i.e
If for some reason you must update xbps-src and the
bootstrap-update target is not enough, it's possible to recreate a masterdir with two simple commands (please note that
zap keeps your
ccache/distcc/host directories intact):
$ ./xbps-src zap $ ./xbps-src binary-bootstrap
Sometimes the bootstrap packages must be updated to the latest available version in repositories, this is accomplished with the
$ ./xbps-src bootstrap-update
Two ways are available to build 32bit packages on x86_64:
The first mode (cross compilation) is as easy as:
$ ./xbps-src -a i686 pkg ...
The second mode (native) needs a new x86
$ ./xbps-src -m masterdir-x86 binary-bootstrap i686 $ ./xbps-src -m masterdir-x86 ...
A native build environment is required to be able to cross compile the bootstrap packages for the musl C library; this is accomplished by installing them via
$ ./xbps-src binary-bootstrap
Now cross compile
base-chroot-musl for your native architecture:
$ ./xbps-src -a x86_64-musl pkg base-chroot-musl
Wait until all packages are built and when ready, prepare a new masterdir with the musl packages:
$ ./xbps-src -m masterdir-x86_64-musl binary-bootstrap x86_64-musl
Your new masterdir is now ready to build natively packages for the musl C library. Try:
$ ./xbps-src -m masterdir-x86_64-musl chroot $ ldd
To see if the musl C dynamic linker is working as expected.
To rebuild all packages in
base-system for your native architecture:
$ ./xbps-src -N pkg base-system
It's also possible to cross compile everything from scratch:
$ ./xbps-src -a <target> -N pkg base-system
Once the build has finished, you can specify the path to the local repository to
# cd void-mklive # make # ./mklive.sh ... -r /path/to/hostdir/binpkgs
