DESCRIPTION
sbuild rebuilds Debian binary packages from the corresponding Debian source, installing any missing source dependencies. The build takes place in a dedicated clean build environment (chroot), rather than on the host system.

sbuild can fetch the Debian source over a network, or it can use locally available sources.

sbuild is given a packages to process as the argument PACKAGE[.dsc]. This argument is in the form of either a debianized package source directory, a source package name along with a version in the form package_version, or a .dsc file. If no arguments are given, the current working directory is passed as an argument.

For arguments given as source directories, dpkg-source is first run to produce a source .dsc file. Then, the package is built using the .dsc produced. For arguments in the form package_version, apt is used to download the source package. For arguments given as a .dsc file, sbuild builds the source packages directly. For .dsc files in remote locations, the source packages are downloaded first, then built.

It is also possible to run external commands with sbuild. See the section EXTERNAL COMMANDS for more on this.

sbuild mails the build logs to a user. It is configured by the configuration files /etc/sbuild/sbuild.conf and ~/.sbuildrc. An example sbuildrc is available in /usr/share/doc/sbuild/examples/example.sbuildrc.

You can build either using a local package with its .dsc file or a remote one by specifying an explicit dpkg version.

Note: When using schroot (recommended), the chroot having the name (or alias) of the specified distribution will be used; schroot uses a chroot named $distribution-$arch-sbuild, $distribution-sbuild, $distribution-$arch or $distribution, in that order of preference. The -c or --chroot option may be used to override the chroot to be used. When configured to use sudo (deprecated), sbuild will look for a symlink to a chroot with the same name as the distribution specified. sbuild will use a symlink to the chroot located in /etc/sbuild/chroot/$distribution, or must be run in a directory containing a chroot-$distribution symlink to the chroot (not recommended, but done for backward compatibility).

OPTIONS

-h, --help
    Display this manual.

-V, --version
    Print version information.

--add-depends=dependency

--add-conflicts=dependency

--add-depends-arch=dependency

--add-conflicts-arch=dependency

--add-depends-indep=dependency

--add-conflicts-indep=dependency
    These options add a build dependencies to the source package being built, in addition to the build dependency information specified in debian/control. These dependencies will be concatenated directly to the Build-Depends, Build-Conflicts, Build-Depends-Arch, Build-Conflicts-Arch, Build-Depends-Indep and Build-Conflicts-Indep dependencies, respectively. The options may be used any number of times to add multiple dependencies. The format is identical to the format used in debian/control.

--arch=architecture
    Build using the architecture specified. A chroot named $distribution-$arch-sbuild or $distribution-arch is searched for, in that order of preference. The chroot must be installed and configured appropriately to build as that architecture, e.g. using personality=linux32 to build i386 packages on an amd64 system. Note that this option is equivalent to "--host=architecture --build=architecture".

--host=architecture
    Build using the host architecture specified. If $host and $build don't match, a chroot named $distribution-$build-$host-sbuild or $distribution-$build-$host is searched for, falling back to $distribution-$host-sbuild or $distribution-$host, in that order of preference. This option is only useful for cross-building when used together with --build.

--build=architecture
    Build using the build architecture specified. This option is only useful for cross-building when used together with --host. If --build is not specified, the default system architecture is assumed.

-A, --arch-all
    Also build Architecture: all packages, i.e. use dpkg-buildpackage -b instead of -B.

--no-arch-all
    Do not build Architecture: all packages, i.e. use dpkg-buildpackage -B instead of -b. This option is the opposite of --arch-all.

-b, --batch
    Operate in batchmode, i.e. write a build-progress file during execution and files on shutdown to facilitate a clean restart.

-c, --chroot=chroot
    Use the specified chroot. If not specified, the default is the first of $distribution-$arch-sbuild, $distribution-sbuild, $distribution-$arch or $distribution that exists.

-d, --dist=distribution
    Fetch source packages from specified distribution.

--archive=archive
    Communicate with specified archive.

-D, --debug
    Enable debug output.

--apt-clean
--no-apt-clean
    Run (or do not run) apt-get clean in the chroot before executing the build, overriding the default setting.

--apt-update
--no-apt-update
    Run (or do not run) apt-get update in the chroot before executing the build, overriding the default setting.

--apt-upgrade
--no-apt-upgrade
    Run (or do not run) apt-get upgrade in the chroot before executing the build, overriding the default setting.

--apt-distupgrade
--no-apt-distupgrade
    Run (or do not run) apt-get distupgrade in the chroot before executing the build, overriding the default setting.

-m, --maintainer=maintainer
    Specify the identity to use for GPG signing packages, and also used as the maintainer for binary NMUs. This does not normally require setting (it defaults to the uploader).

-e, --uploader=uploader
    Passed to dpkg-genchanges and is used to set the Changed-by: field in the .changes file(s).

-k, --keyid=key-id
    Passed to dpkg-genchanges and is used to set the key to sign the .changes file(s). Default is not using any key.

-j, --jobs=n
    Number of jobs to run simultaneously. Passed through to dpkg-buildpackage.

--debbuildopt=option
    Pass the specified option directly to dpkg-buildpackage.

--debbuildopts=options
    Pass the specified options directly to dpkg-buildpackage. The options should be separated by spaces. If any options contain spaces, use --debbuildopt instead.

--dpkg-source-opt=options
    Pass the specified options directly to dpkg-source. This is only used when creating a source package from a Debianized source directory.
    NOTE: The '-b' option will always be passed to dpkg-source.

--dpkg-source-opts=options
    Extra options to be appended to existing options passed to dpkg-source.

--mail-log-to=email-address
    Send the build log to the specified email address. This overrides the $mailto configuration option.

-n, --nolog
    Do not create a package log file in the $log_dir directory and no build log file, but print everything to stdout. Also do not send any log mails.

-p, --purge=purge-mode
    Convenience option to set purge-mode for build directory, build dependencies and session.

--profiles=profile[,...]"
    Specify the profile(s) we build, as a comma-separated list. Defaults to the space separated list of profiles in the DEB_BUILD_PROFILES environment variable.

--purge-build=purge-mode
    purge-mode determines if the build directory will be deleted after a build. Possible values are always (default), never, and successful.

--purge-deps=purge-mode
    purge-mode determines if the build dependencies will be removed after a build. Possible values are always (default), never, and successful.

--purge-session=purge-mode
    Purge the schroot session following a build. This is useful in conjunction with the --purge-build and --purge-deps options when using snapshot chroots, since by default the snapshot will be deleted. Possible values are always (default), never, and successful.

-s, --source
    Also build source package, i.e. use dpkg-buildpackage without -B.

--no-source
    Don't build source package, i.e. use dpkg-buildpackage with -B. This option is the opposite of --source.

--force-orig-source
    When used with in conjunction with -s, this option forces the inclusion of the orig.tar.gz file in the generated .changes file, even in cases where it would not normally be included, i.e. use dpkg-buildpackage -sa.

--use-snapshot
    Installs the latest snapshot gcc compiler from the gcc-snapshot package, and alters the build environment to use the snapshot compiler for the build.

-v, --verbose
    Be verbose, i.e. all information goes to stdout as well as to the log files.

-q, --quiet
    Be quiet. This is the opposite of --verbose.

--make-binNMU=changelog-entry
    With this option, sbuild will create a new changelog entry in debian/changelog of every package built. The version number will be in the format for binary-only NMUs (see --binNMU); the maintainer is set to the maintainer name configured for sbuild. changelog-entry will be used as the changelog entry following “Binary-only non-maintainer upload for ARCH -- no source changes”. Please note that the versions in the PACKAGE_VERSION[.dsc] arguments still have to be the unmodified (non-NMU ones) so that the sources can be found. The version number in log files and mails will be modified by sbuild automatically.

--binNMU=NMU-version
    The version number of the binary NMU. This should be used in conjunction with --make-binNMU. version is a single number for the (+bn) format used for binary NMUs.

--append-to-version=string
    This option is similar to --make-binNMU except that it allows the user to specify an arbitrary string to be appended to the version number (immediately before the '+' in the Debian revision if --make-binNMU is also provided).

--run-lintian
    Run lintian after a successful build.

--no-run-lintian
    Don't run lintian after a successful build. If sbuild is configured to run lintian by default, this option will prevent lintian being run.

--lintian-opt=options
    Run lintian with the specified options.

--lintian-opts=options
    Append extra options to existing options passed to lintian.

--run-piuparts
    Run piuparts after a successful build.

--no-run-piuparts
    Don't run piuparts after a successful build. If sbuild is configured to run piuparts by default, this option will prevent piuparts being run.

--piuparts-opt=options
    Run piuparts with the specified options.

--piuparts-opts=options
    Append extra options to existing options passed to piuparts.

--piuparts-root-arg=options
    Add an argument that is used to launch piuparts as root. If no arguments are specified, piuparts will be launched via sudo.

--piuparts-root-args=options
    Add arguments that are used to launch piuparts as root. If no arguments are specified, piuparts will be launched via sudo.

--pre-build-commands=string
    Run this command before a build starts. This option can be used multiple times to add multiple commands.

--chroot-setup-commands=string
    Run these commands when a chroot is setup, before dependencies are installed. This option can be used multiple times to add multiple commands.

--starting-build-commands=string
    Run these commands after dependencies are installed, just before the package build starts. This option can be used multiple times to add multiple commands.

--finished-build-commands=string
    Run these commands immediately after the timed package build finishes. This option can be used multiple times to add multiple commands.

--chroot-cleanup-commands=string
    Run these commands when a chroot is cleaned up, before build directory is purged. This option can be used multiple times to add multiple commands.

--post-build-commands=string
    Run this command after a successful build. This option can be used multiple times to add multiple commands.

--log-external-command-output
    Write output from external commands to the build log.

--log-external-command-error
    Write error output from external commands to the build log.

--setup-hook=hook-script DEPRECATED
    This option is deprecated. Use of this option will add hook-script to the external commands to run via chroot-setup-commands.

--build-dep-resolver=resolver
    Use the specified resolver to handle selecting the build dependencies. Supported resolvers are apt (the default), aptitude and xapt. The apt resolver is the most appropriate resolver for most users, for building for unstable, stable and other distributions. If alternative build dependencies are used (excluding architecture restrictions), only the first alternative will be used; the others will be ignored. The aptitude resolver is very similar, but smarter and slower, and it will consider all alternatives by default; it is suited to more complex situations, such as building packages for the experimental distribution, where packages need installing from multiple suites (unstable and experimental). Due to performance and other issues (bug #139615), aptitude is not recommended for use by default. The xapt resolver is intended only for cross-building, and is a temporary transitional feature which will be removed following the complete introduction of multi-arch support.

--resolve-alternatives
    Allow the use of alternatives in Build-Depends, Build-Depends-Arch and Build-Depends-Indep. This is the default for the aptitude dependency resolver.

--no-resolve-alternatives
    Do not allow the use of alternatives in Build-Depends, Build-Depends-Arch and Build-Depends-Indep. Note that alternatives for the same package (e.g. different versions) are still allowed. This is the default for the apt and xapt dependency resolvers.

--extra-package=package.deb
    Make package.deb available for build-dependency resolution, by adding it to a temporary archive created by sbuild. This makes it easier to build packages against locally-built build depenencies, without waiting for those packages to enter the main archive, or going through the hassle of maintaining a local archive and making it accessible inside the chroot. package.deb is copied into the chroot, so it can refer to any path on the host system.

--extra-repository=spec
    Add a repository to the list of apt sources during the package build. The repository specification is a line suitable for an apt sources.list(5) file. For instance, you might use --extra-repository="deb http://ftp.debian.org/debian experimental main" to allow packages in the experimental distribution to fulfill build-dependencies. Note that the build chroot must already trust the key of this repository (see apt-secure(8)).

EXTERNAL COMMANDS
Support to run external commands during an sbuild run is provided. A set of external commands can be run at various stages of a build. Providing commands to run is done through the appropriate options given on the command line and through the use of the configuration files. In the configuration file, the list of commands to run are placed in a hash of arrays of arrays of strings corresponding to the commands to run.

There are three sets of commands. The pre/post-build- commands are run external to the chroot. The chroot-setup/cleanup- commands and Starting/Finished-Build- commands are run inside the chroot. They are all run as root except the Starting/Finishing-build- commands, which are run as the current sbuild user.

Here is a summary of the ordering, user, internal/external to chroot for each command hook
Initialise chroot session
--pre-build-commands       root  outside chroot
Setup the chroot and variables
--chroot-setup-commands    root  inside chroot
Update and upgrade packages
Install Dependencies
--starting-build-commands  user  inside chroot
Do actual build (dpkg-buildpackage)
--finished-build-commands  user  inside chroot
Run lintian (if configured)
Cleanup build files and dependencies
--chroot-cleanup-commands  root  inside chroot
Close schroot session
Run piuparts (if configured)
--post-build-commands      root  outside chroot

Here's an example of how to edit the configuration files to run "foo" and "bar" with arguments before a build starts.

$external_commands = {
"pre-build-commands" => [
['foo', 'arg1', 'arg2'],
['bar', 'arg1', 'arg2', 'arg3'],
],
};

Hash keys for commands to run at other stages have the same name as their corresponding command-line option name without the preceding '--'.

Here's an example of how to do the same with the previous example, except using the --pre-build-commands option.

$ sbuild \
--pre-build-commands='foo arg1 arg2' \
--pre-build-commands='bar arg1 arg2 arg3'

Besides running external commands, sbuild can also detect the use of certain percent escapes given as arguments. These are used to allow for a command to be supplied with a certain argument depending on the escape given. For example, it could be possible to have an external command be given the path to a .changes file.

Here is a listing of keywords and a description of what it's converted to.

%%  Used to escape a '%'.

%d, %SBUILD_DSC
    These escapes are converted to the absolute path to a package's .dsc file.

%c, %SBUILD_CHANGES
    These escapes are converted to the absolute path to a package's source .changes file.

%a, %SBUILD_HOST_ARCH
    These escapes are converted to the debian name of the architecture the build is being built for (e.g amd64, armhf).

%r, %SBUILD_CHROOT_DIR
    These escapes are converted to the absolute path on the host to the root directory of the chroot. This variable is not set if the external command is run inside the chroot.

%b, %SBUILD_BUILD_DIR
    These escapes are converted to the absolute path to the build directory inside the chroot.

%p, %SBUILD_PKGBUILD_DIR
    These escapes are converted to the absolute path to the package build directory inside the chroot.

Percent escapes are only substituted when an appropriate value is defined for them. At other times, it is left unchanged. For example, a .changes file is only defined at the end of a build, so using %c will only be substituted for post-build-commands.

Here's an example of using an escape to run a program foo on a .changes file after a build is done.

$ sbuild --post-build-commands \
'foo %SBUILD_CHANGES'

One final note, external commands are processed in the order they are given. Also, the commands given in a configuration file are processed first, then the commands given through the command line options.

LOCAL ARCHIVE
The apt and aptitude resolvers create a local archive for installing build dependencies. This is an internal implementation detail of the build dependency resolver, which is not user configurable, and is intended to be entirely transparent to the user. The local archive exists only transiently during the package build. It does not persist across builds, and it is only used to store the dummy dependency packages created for a single build.

The dependency resolvers do the following:

•   Create a dummy dependency package. This contains the Build-Depends (and optionally Build-Depends-Arch and Build-Depends-Indep) as Depends, and Build-Conflicts (and optionally Build-Conflicts-Arch and Build-Conflicts-Indep) as Conflicts.

•   Install the dummy dependency package into the local archive,

•   Generate the Packages, Sources and Release files.

•   Write a sources.list file for the local archive into /etc/apt/sources.list.d.

•   Inject the lists directly into /var/lib/apt/lists. This step is to save running updating all apt sources which is undesirable during a build; apt and aptitude do not support updating a single source at present.

•   Regenerate the apt caches to ensure everything is in sync.

•   Install the dummy dependency package with apt or aptitude; the dummy package is pulled from the local apt archive, while all its dependencies are pulled from the regular configured apt sources.

At the end of the build, the local archive is removed, along with the rest of the build tree.

ENVIRONMENT VARIABLES
The following environment variables are used by sbuild:

HOME
    The home directory of the user.

LOGNAME
    Used in lockfiles.

FILES

/etc/sbuild/sbuild.conf
    Configuration, maintained by the system administrator. This may be used to override the defaults.

/etc/sbuild/chroot
    Directory containing symbolic links to chroots. This is only used for sudo chroot access; schroot access uses the schroot chroot configuration.
