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, a source package name, 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 or package, 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. A custom path to a configuration file can also be specified through setting the SBUILD_CONFIG environment variable to the path of an additional configuration file.

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

Options set on the command line overwrite settings made in the configuration file.

-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. These command line options append to the MANUAL_DEPENDS, MANUAL_CONFLICTS, MANUAL_DEPENDS_ARCH, MANUAL_CONFLICTS_ARCH, MANUAL_DEPENDS_INDEP and MANUAL_CONFLICTS_INDEP configuration variables, respectively. See sbuild.conf(5) for more information.

--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". This command line option sets the HOST_ARCH and BUILD_ARCH configuration variables. See sbuild.conf(5) for more information.

--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 $distribution-$build-sbuild or $distribution-$build, in that order of preference. This option is only useful for cross-building when used together with --build. This command line option sets the HOST_ARCH configuration variable. See sbuild.conf(5) for more information.

--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. This command line option sets the BUILD_ARCH configuration variable. See sbuild.conf(5) for more information.

-A, --arch-all

Also build Architecture: all packages. This option is the opposite of --no-arch-all. See the section BUILD ARTIFACTS for more information. This command line option sets the BUILD_ARCH_ALL configuration variable. See sbuild.conf(5) for more information.

--no-arch-all

Do not build Architecture: all packages. This is the default behaviour. This option is the opposite of --arch-all. See the section BUILD ARTIFACTS for more information. This command line option sets the BUILD_ARCH_ALL configuration variable. See sbuild.conf(5) for more information.

--arch-any

Build Architecture: any packages. This is the default behavior. This option is the opposite of --no-arch-any. See the section BUILD ARTIFACTS for more information. This command line option sets the BUILD_ARCH_ANY configuration variable. See sbuild.conf(5) for more information.

--no-arch-any

Do not build Architecture: any packages. This option is the opposite of --arch-any and only useful when used together with --arch-all or --source. See the section BUILD ARTIFACTS for more information. This command line option sets the BUILD_ARCH_ANY configuration variable. See sbuild.conf(5) for more information.

-b, --batch

Operate in batchmode, i.e. write a build-progress file during execution and files on shutdown to facilitate a clean restart. This command line option sets the BATCH_MODE configuration variable. See sbuild.conf(5) for more information.

-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. This command line option sets the CHROOT configuration variable. See sbuild.conf(5) for more information.

--chroot-mode=schroot|sudo|adt

Select the desired chroot mode. Four values are possible: schroot (the default), sudo (which uses sudo to execute chroot in a directory from /etc/sbuild/chroot or ./chroot) and adt which uses the adt-virt-* binaries (selectable via the --adt-virt-server option). This command line option sets the CHROOT_MODE configuration variable. See sbuild.conf(5) for more information.

-d, --dist=distribution

Explicitly set the distribution for the package build. This will be selecting the correct chroot to use and also sets the value of the Distribution field in the created .changes file. Setting this option is necessary when giving sbuild a .dsc file or a plain source package name to build. In the latter case it specifies the distribution the source package is fetched from. This command line option sets the DISTRIBUTION configuration variable. See sbuild.conf(5) for more information.

--archive=archive

Communicate with specified archive. This command line option sets the ARCHIVE configuration variable. See sbuild.conf(5) for more information.

--debbuildopts=options

Pass the specified options directly to dpkg-buildpackage in addition to the options already passed by sbuild. The argument will be split by whitespaces and the resulting array passed to the dpkg-buildpackage invocation. If any options contain spaces, use --debbuildopt for them. This option can be passed multiple times and can be freely mixed with the --debbuildopt option. Options will be passed to dpkg-buildpackage in the order that the --debbuildopt and --debbuildopts options are given on the command line. This command line option appends to the DPKG_BUILDPACKAGE_USER_OPTIONS configuration variable. See sbuild.conf(5) for more information.

--dpkg-source-opt=optionsPass the specified option directly to dpkg-source in addition to the options

Pass the specified option directly to dpkg-source in addition to the options already passed by sbuild. This is only used when creating a source package from a Debianized source directory. This option can be passed multiple times (once per dpkg-source option) and can be freely mixed with the --dpkg-source-opts option. Options will be passed to dpkg-source in the order that the --dpkg-source-opt and --dpkg-source-opts options are given on the command line. This command line option appends to the DPKG_SOURCE_OPTIONS configuration variable. See sbuild.conf(5) for more information.
NOTE: The '-b' option will always be passed to dpkg-source.

--dpkg-source-opts=options

Pass the specified options directly to dpkg-source in addition to the options already passed by sbuild. The argument will be split by whitespaces and the resulting array passed to the dpkg-source invocation. This is only used when creating a source package from a Debianized source directory. If any options contain spaces, use --dpkg-source-opt for them. This option can be passed multiple times and can be freely mixed with the --dpkg-source-opt option. Options will be passed to dpkg-source in the order that the --dpkg-source-opt and --dpkg-source-opts options are given on the command line.

-p, --purge=purge-mode

Convenience option to set purge-mode for build directory, build dependencies and session. This command line option sets the PURGE_BUILD_DEPS, PURGE_BUILD_DIRECTORY and PURGE_SESSION configuration variables. See sbuild.conf(5) for more information.

--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. This command line option sets the PURGE_BUILD_DIRECTORY configuration variable. See sbuild.conf(5) for more information.

--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. This command line option sets the PURGE_BUILD_DEPS configuration variable. See sbuild.conf(5) for more information.

--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. This command line option sets the PURGE_SESSION configuration variable. See sbuild.conf(5) for more information.

-s, --source

Build the source package in addition to the other requested build artifacts. By default, the dsc will not be rewritten because the source package is the input to sbuild, not its output. Even when running from an unpacked source tree sbuild will first build the source package using dpkg-source and then pass that on to the sbuild machinery. Use this option only when you know what you are doing. This will rewrite the original dsc passed to sbuild. See the section BUILD ARTIFACTS for more information. This command line option sets the BUILD_SOURCE configuration variable. See sbuild.conf(5) for more information.

--no-source

Don't rebuild the source package. This is the default. It is the opposite of --source. See the section BUILD ARTIFACTS for more information. This command line option sets the BUILD_SOURCE configuration variable. See sbuild.conf(5) for more information.

--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. This command line option sets the FORCE_ORIG_SOURCE configuration variable. See sbuild.conf(5) for more information.

--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. Specifically, this option appends /usr/lib/gcc-snapshot/lib to the value of the LD_LIBRARY_PATH configuration variable and /usr/lib/gcc-snapshot/bin to the value of the PATH configuration variable. It also sets the GCC_SNAPSHOT configuration variable. See sbuild.conf(5) for more information.

-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. This command line option sets the BIN_NMU configuration variable and sets the BIN_NMU_VERSION configuration variable to 1 if it was not set yet, for example by the --binNMU option. See sbuild.conf(5) for more information.

--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. This command line option sets the BIN_NMU_VERSION configuration variable. See sbuild.conf(5) for more information.

--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). This command line option sets the APPEND_TO_VERSION configuration variable. See sbuild.conf(5) for more information.

--clean-source

When executing sbuild from within an unpacked source tree, execute the debian/rules clean target. This is the default and might require some of the build dependencies installed on the host. This command line option sets the CLEAN_SOURCE configuration variable. See sbuild.conf(5) for more information.

--no-clean-source

When executing sbuild from within an unpacked source tree, do not run the debian/rules clean target before building the source package. Only set this if you start from a clean checkout and you know what you are doing. This command line option sets the CLEAN_SOURCE configuration variable. See sbuild.conf(5) for more information.

--run-lintian

This option is deprecated. Use of this option will add hook-script to the external commands to run via chroot-setup-commands. This command line option sets the CHROOT_SETUP_SCRIPT configuration variable and appends to the EXTERNAL_COMMENDS configuration variable. See sbuild.conf(5) for more information.

--build-dep-resolver=resolver

Use the specified resolver to handle selecting the build dependencies. Supported resolvers are apt (the default), aptitude, aspcud 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. If the dependency situation is so complex that neither apt nor aptitude are able to find a solution, then you can use the aspcud resolver. This resolver uses apt-cudf to ask aspcud, a real solver (in the math sense), to find a solution to the installation problem. Since aspcud uses a real solver (an ASP solver) it will always find a solution if one exists. The solution found by the aspcud resolver can be refined by changing the default optimization criteria through the --aspcud-criteria option. 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. This command line option sets the BUILD_DEP_RESOLVER configuration variable. See sbuild.conf(5) for more information.

--aspcud-criteria=criteria

Optimization criteria in extended MISC 2012 syntax passed to aspcud through apt-cudf. Optimization criteria are separated by commas, sorted by decreasing order of priority and are prefixed with a polarity (+ to maximize and - to minimize). The default criteria is -removed,-changed,-new which first minimizes the number of removed packages, then the number of changed packages (up or downgrades) and then the number of new packages. A common task is to minimize the number of packages from experimental. To do this you can add a criteria like -count(solution,APT-Release:=/a=experimental/) to the default criteria. This will then minimize the number of packages in the solution which contain the string a=experimental in the APT-Release field of the EDSP output created by apt. For more help on how to write optimization criteria, see the apt-cudf(1) man page. Specifically the help on the --criteria option. This command line option sets the ASPCUD_CRITERIA configuration variable. See sbuild.conf(5) for more information.

--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. This command line option sets the RESOLVE_ALTERNATIVES configuration variable. See sbuild.conf(5) for more information.

--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. This command line option sets the RESOLVE_ALTERNATIVES configuration variable. See sbuild.conf(5) for more information.

--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. This command line option appends to the EXTRA_PACKAGES configuration variable. See sbuild.conf(5) for more information.

--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://httpredir.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 or a key must be given with the --extra-repository-key flag (see apt-secure(8)). This command line option appends to the EXTRA_REPOSITORIES configuration variable. See sbuild.conf(5) for more information.

--extra-repository-key=file.asc

Add file.asc to the list of trusted keys inside the chroot. The key is read from the filename given, and added to the trusted keys. For more information, see apt-secure(8). This flag is particularly useful if the target in --extra-repository is not signed with a key that's trusted by the base chroot. This command line option appends to the EXTRA_REPOSITORY_KEYS configuration variable. See sbuild.conf(5) for more information.

--build-path=string

By default the package is built in a path of the following format /build/packagename-XXXXXX/packagename-version/ where XXXXXX is a random ascii string. This option allows one to specify a custom path where the package is built inside the chroot. Notice that the sbuild user in the chroot must have permissions to create the path. Common writable locations are subdirectories of /tmp or /build. The buildpath must be an empty directory because the last component of the path will be removed after the build is finished. If you are running multiple sbuild instances with the same build path in parallel for the same package, make sure that your build path is not in a directory commonly mounted by all sbuild instances (like /tmp or /home). In that case, use for example /build instead. Otherwise, your builds will probably fail or contain wrong content. This command line option sets the BUILD_PATH configuration variable. See sbuild.conf(5) for more information.

--adt-virt-server=schroot|lxc|chroot|qemu|ssh

The adt virtualization server. Can be specified with or without the adt-virt- prefix. For instance, the following set of command line options will use the adt-virt-schroot backend for a package build: --chroot-mode=adt --adt-virt-server=schroot --chroot unstable-amd64-sbuild The value of the --chroot option will be passed as the last positional argument to the adt-virt-* invocation. Thus, the value of the --chroot option becomes the image name of the virtual machine in case of adt-virt-qemu, the lxc-container name in case of adt-virt-lxc, the path to the chroot in case of adt-virt-chroot, the name of the schroot in case of adt-virt-schroot and so on. This command line option sets the ADT_VIRT_SERVER configuration variable. See sbuild.conf(5) for more information.

--adt-virt-server-opt=string

Pass the specified option directly to the respective adt-virt-* virtualization server in addition to the options already passed by sbuild. This option can be passed multiple times (once per adt-virt-* option) and can be freely mixed with the --adt-virt-server-opts option. Options will be passed to the respective adt-virt-* virtualization server in the order that the --adt-virt-server-opt and --adt-virt-server-opts options are given on the command line. See the manual pages of the respective adt-virt-* commands for more information. This command line option appends to the ADT_VIRT_SERVER_OPTIONS configuration variable. See sbuild.conf(5) for more information.

--adt-virt-server-opts=options

Pass the specified options directly to the respective adt-virt-* virtualization server in addition to the options already passed by sbuild. The argument will be split by whitespaces and the resulting array passed to the adt-virt-* invocation. If any options contain spaces, use --adt-virt-server-opt for them. This option can be passed multiple times and can be freely mixed with the --adt-virt-server-opts option. Options will be passed to the respective adt-virt-* virtualization server in the order that the --adt-virt-server-opt and --adt-virt-server-opts options are given on the command line. See the manual pages of the respective adt-virt-* commands for more information. This command line option appends to the ADT_VIRT_SERVER_OPTIONS configuration variable. See sbuild.conf(5) for more information.

--sbuild-mode=mode

Behaviour changes for use in a buildd environment. This command line option sets the SBUILD_MODE configuration variable. See sbuild.conf(5) for more information.

- stats-dir=directory

Directory for writing build statistics to. This command line option sets the STATS_DIR configuration variable. See sbuild.conf(5) for more information.

BUILD ARTIFACTS

Sbuild is meant to be used to build architecture specific binary packages from a given source package. In addition, sbuild is also able to generate architecture independent binary packages as well as to rebuild the original source package that was used as input. In summary, sbuild is able to build architecture specific binary packages, architecture independent binary packages and source packages. What ends up being built is determined by the configuration variables BUILD_ARCH_ANY, BUILD_ARCH_ALL and BUILD_SOURCE, respectively. See sbuild.conf(5) for a detailed explanation of these configuration variables.

By default, only BUILD_ARCH_ANY is set to true while BUILD_ARCH_ALL and BUILD_SOURCE are set to false. So by default only architecture specific binary packages will be built. This behaviour can be changed either by using command line options or by modifying the configuration variables in your ~/.sbuildrc. The relevant command line options to change the values of BUILD_ARCH_ANY, BUILD_ARCH_ALL and BUILD_SOURCE are --arch-any/--no-arch-any, --arch-all/--no-arch-all and --source/--no-source, respectively.

The values of BUILD_ARCH_ANY, BUILD_ARCH_ALL and BUILD_SOURCE change the parameter that dpkg-buildpackage is called with. The following table displays the argument passed to dpkg-buildpackage in the last column depending on the configuration options in the first three columns.

BUILD_ARCH_ANY	BUILD_ARCH_ALL	BUILD_SOURCE	dpkg-buildpackage flag
false	false	false	invalid
false	false	true	-S
false	true	false	-A
false	true	true	-g
true	false	false	-B
true	false	true	-G
true	true	false	-b
true	true	true	no option

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 several 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. chroot-update-failed and build-deps-failed runs similarly to chroot-setup: in the chroot as root. build-failed runs similarly to finished-build: in the chroot as the user.

Here is a summary of the ordering, user, internal/external to chroot for each command hook

The following table shows each command hook in the context of the tasks sbuild performs. The column root shows whether the command is run as root (yes) or not (no). The column chroot shows whether the command is run inside our outside the chroot. The remaining columns show the percent escapes that are defined in each command. Percent escapes that are available in all commands (%%, %a, %b, %s) are omitted. The value maybe in the column for the %d and %p escapes means that the value can not relied upon to be defined in these stages. More specifically, these escapes will not be defined at these points if the user specified a source package name without a version on the command line. In that case, the version will only become known after the source package has been retrieved in the "Fetch and unpack source package" stage.

command/action	root	chroot	%c	%e	%d,%p
Initialise chroot session
--pre-build-commands	yes	outside	no	yes	maybe
Setup the chroot and variables
--chroot-setup-commands	yes	inside	no	no	maybe
Update and upgrade packages
--chroot-update-failed-commands	yes	inside	no	no	maybe
Fetch and unpack source package
Install Dependencies
--build-deps-failed-commands	yes	inside	no	no	yes
--starting-build-commands	no	inside	no	no	yes
Run dpkg-buildpackage
--build-failed-commands	no	inside	no	no	yes
--finished-build-commands	no	inside	no	no	yes
Run lintian (if configured)
Cleanup build files and dependencies
--chroot-cleanup-commands	yes	inside	yes	no	yes
Close schroot session
Run piuparts (if configured)
--post-build-commands	yes	outside	yes	yes	yes

The commands can be given in the configuration files. They can be given as strings or as a list of arguments. For example, to run "foo" and "bar" with arguments before a build starts, specifying the "foo" command as a list and "bar" as a string, one could do this:

$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'

Note that all these commands are executed through the shell in "/bin/sh". If specifying the command as a list in the config file, very few shell facilities are supported: no redirection, no command concatenation with ; and so on. When passing a string (in the config file or on the commandline), the string is passed as-is to the shell. So all shell facilities are available, given that you escape everything properly, as you would in an interactive shell.

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. This variable is only set after the build is finished, i.e in --chroot-cleanup-commands and --post-build-commands.

%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).

%e, %SBUILD_CHROOT_EXEC

These escapes are converted to a command which can be executed on a host and can be given arguments which will then be executed inside the chroot. Standard input and output of the process started inside the chroot are connected to the program executed on the host. Thus, this command can also be used to copy data into the chroot and out of the chroot. The working directory of the process started inside the chroot is the root directory of the chroot. The process is started as the root user. This variable is not set if the external command is run inside the chroot. Thus this escape is only available for --pre-build-commands and --post-build-commands.

%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.

%s, %SBUILD_SHELL

This is converted to a command to spawn an interactive "bash" shell

Percent escapes are only substituted when an appropriate value is defined for them. At other times, it is left unchanged. In practice this means that there are only two escapes that are not available in all external commands: %c and %e. 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'

And here's an example that will spawn an interactive shell to investigate the problem whenever the build failed:

$ sbuild --build-failed-commands '%SBUILD_SHELL'

The following example would copy a file from the host into the chroot:

$ sbuild --pre-build-commands \
'cat blub.txt | %SBUILD_CHROOT_EXEC sh -c "cat > blub.txt"'

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.

FILES
