NAME
sbuild.conf - configuration file for sbuild
DESCRIPTION
sbuild.conf is a Perl script which is sourced by sbuild to permit configuration. It is run in a sandbox
and restricted to setting a small number of variables, detailed below, which may be set to configure the
behaviour of sbuild. Each variable has an internal name, shown in all caps, and a perl variable showing
the default setting. Note that the internal name is not accessible within sbuild.conf; only the variable
may be assigned. Also note that some of the defaults are set to be unique for each build, and so some of
the defaults shown here are unique to the user and system used to build sbuild, and will be different for
your system.
While sbuild permits many aspects of its behaviour to be configured, this should not normally be
required. The defaults should be adequate for most uses, and should only be changed if you are doing
something more advanced, or have specialist requirements.
CONFIGURATION
Build environment
LD_LIBRARY_PATH
STRING type. Library search path to use inside the chroot.
Default:
$ld_library_path = undef;
PATH STRING type. PATH to set when running dpkg-buildpackage.
Default:
$path = '/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games';
Build options
APPEND_TO_VERSION
STRING type. Suffix to append to version number. May be useful for derivative distributions.
Default:
$append_to_version = undef;
BUILD_ARCH
STRING type. Build architecture (Arch we are building on).
build_arch = ...;
BUILD_ARCH_ALL
BOOL type. Build architecture: all packages by default
Default:
$build_arch_all = 0;
BUILD_ARCH_ANY
BOOL type. Build architecture: any packages by default
Default:
$build_arch_any = 1;
BUILD_ENV_CMND
STRING type. This command is run with the dpkg-buildpackage command line passed to it (in the
chroot, if doing a chrooted build). It is used by the sparc buildd (which is sparc64) to call the
wrapper script that sets the environment to sparc (32-bit). It could be used for other build
environment setup scripts. Note that this is superceded by schroot's 'command-prefix' option
Default:
$build_env_cmnd = '';
BUILD_PATH
STRING type. 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.
Default:
$build_path = undef;
BUILD_PROFILES
STRING type. Build profiles. Separated by spaces.
Default:
$build_profiles = '';
BUILD_SOURCE
BOOL type. By default, do not build a source package (binary only build). Set to 1 to force
creation of a source package, but note that this is inappropriate for binary NMUs, where the
option will always be disabled.
Default:
$build_source = 0;
CHECK_SPACE
BOOL type. Check free disk space prior to starting a build. sbuild requires the free space to be
at least twice the size of the unpacked sources to allow a build to proceed. Can be disabled to
allow building if space is very limited, but the threshold to abort a build has been exceeded
despite there being sufficient space for the build to complete.
Default:
$check_space = 1;
CLEAN_SOURCE
BOOL type. When running sbuild from within an unpacked source tree, run the 'clean' target before
generating the source package. This might require some of the build dependencies necessary for
running the 'clean' target to be installed on the host machine. Only disable if you start from a
clean checkout and you know what you are doing.
Default:
$clean_source = 1;
DISTRIBUTION
STRING type. Default distribution. By default, no distribution is defined, and the user must
specify it with the -d option. However, a default may be configured here if desired. Users must
take care not to upload to the wrong distribution when this option is set, for example
experimental packages will be built for upload to unstable when this is not what is required.
Default:
$distribution = undef;
FORCE_ORIG_SOURCE
BOOL type. By default, the -s option only includes the .orig.tar.gz when needed (i.e. when the
Debian revision is 0 or 1). By setting this option to 1, the .orig.tar.gz will always be included
when -s is used. This is equivalent to --force-orig-source.
Default:
$force_orig_source = 0;
GCC_SNAPSHOT
BOOL type. Build using current GCC snapshot?
Default:
$gcc_snapshot = 0;
HOST_ARCH
STRING type. Host architecture (Arch we are building for)
host_arch = ...;
PGP_OPTIONS
ARRAY:STRING type. Additional signing options for dpkg-buildpackage
Default:
$pgp_options = [
'-us',
'-uc'
];
TOOLCHAIN_REGEX
ARRAY:STRING type. Regular expressions identifying toolchain packages. Note that for backward
compatibility, this is also settable using the array @toolchain_regex (deprecated), rather than an
array reference.
Default:
$toolchain_regex = [
'binutils$',
'dpkg-dev$',
'gcc-[\d.]+$',
'g\+\+-[\d.]+$',
'libstdc\+\+',
'libc[\d.]+-dev$',
'linux-kernel-headers$',
'linux-libc-dev$',
'gnumach-dev$',
'hurd-dev$',
'kfreebsd-kernel-headers$'
];
Build timeouts
INDIVIDUAL_STALLED_PKG_TIMEOUT
HASH:NUMERIC type. Some packages may exceed the general timeout (e.g. redirecting output to a
file) and need a different timeout. This has is a mapping between source package name and
timeout. Note that for backward compatibility, this is also settable using the hash
%individual_stalled_pkg_timeout (deprecated) , rather than a hash reference. Example:
%individual_stalled_pkg_timeout = (smalleiffel => 300,
jade => 300,
atlas => 300,
glibc => 1000,
'gcc-3.3' => 300,
kwave => 600);
Default:
$individual_stalled_pkg_timeout = {};
LOCK_INTERVAL
NUMERIC type. Lock wait interval (seconds). Maximum wait time is (max_lock_trys x
lock_interval).
Default:
$lock_interval = 5;
MAX_LOCK_TRYS
NUMERIC type. Number of times to try waiting for a lock.
Default:
$max_lock_trys = 120;
STALLED_PKG_TIMEOUT
NUMERIC type. Time (in minutes) of inactivity after which a build is terminated. Activity is
measured by output to the log file.
Default:
$stalled_pkg_timeout = 150;
Build validation
LINTIAN
STRING type. Path to lintian binary
Default:

Default:
$piuparts_opts = [];
PIUPARTS_ROOT_ARGS
ARRAY:STRING type. Preceding arguments to launch piuparts as root. If no arguments are specified,
piuparts will be launched via sudo.
Default:
$piuparts_root_args = [];

Chroot options
APT_ALLOW_UNAUTHENTICATED
BOOL type. Force APT to accept unauthenticated packages. By default, unauthenticated packages
are not allowed. This is to keep the build environment secure, using apt-secure(8). By setting
this to 1, APT::Get::AllowUnauthenticated is set to "true" when running apt-get. This is disabled
by default: only enable it if you know what you are doing.
Default:
$apt_allow_unauthenticated = 0;

"successful", and "always"
Default:
$purge_build_directory = 'always';
PURGE_SESSION
STRING type. Purge the schroot session following a build. This is useful in conjunction with the
--purge and --purge-deps options when using snapshot chroots, since by default the snapshot will
be deleted. Possible values are "always" (default), "never", and "successful"
Default:
$purge_session = 'always';
Core options
ARCHIVE
STRING type. Archive being built. Only set in build log. This might be useful for derivative
distributions.
Default:
$archive = undef;
BUILD_DIR
STRING type. This option is deprecated. Directory for chroot symlinks and sbuild logs. Defaults
to the current directory if unspecified. It is used as the location of chroot symlinks (obsolete)
and for current build log symlinks and some build logs. There is no default; if unset, it
defaults to the current working directory. $HOME/build is another common configuration. Example:
$build_dir = '/home/pete/build';
build_dir = ...;
BUILD_ENVIRONMENT
HASH:STRING type. Environment to set during the build. Defaults to setting PATH and
LD_LIBRARY_PATH only. Note that these environment variables are not subject to filtering with
ENVIRONMENT_FILTER. Example: Example:
$build_environment = {
'CCACHE_DIR' => '/build/cache'
};
Default:
$build_environment = {};
BUILD_USER
STRING type. Username used for running dpkg-buildpackage. By default the user running sbuild is
used within the chroot as well but that might allow a process from within the chroot to break out
of the chroot by attaching to a process running outside the chroot with eg. gdb and then becoming
root inside the chroot through schroot and thus be able to leave the chroot.
build_user = ...;
CORE_DEPENDS
ARRAY:STRING type. Packages which must be installed in the chroot for all builds.
Default:
$core_depends = [
'build-essential:native',
'fakeroot:native'
];
ENVIRONMENT_FILTER
ARRAY:STRING type. Only environment variables matching one of the regular expressions in this
arrayref will be passed to dpkg-buildpackage and other programs run by sbuild.
Default:
$environment_filter = [
'^PATH$',
'^DEB(IAN|SIGN)?_[A-Z_]+$',
'^(C(PP|XX)?|LD|F)FLAGS(_APPEND)?$',
'^USER(NAME)?$',
'^LOGNAME$',
'^HOME$',
'^TERM$',
'^SHELL$'
];
JOB_FILE
STRING type. Job status file (only used in batch mode)
Default:
$job_file = 'build-progress';
SBUILD_MODE
STRING type. sbuild behaviour; possible values are "user" (exit status reports build failures)
and "buildd" (exit status does not report build failures) for use in a buildd setup. "buildd"
also currently implies enabling of "legacy features" such as chroot symlinks in the build
directory and the creation of current symlinks in the build directory.
Default:
$sbuild_mode = 'user';
Dependency resolution
BUILD_DEP_RESOLVER
STRING type. Build dependency resolver. The 'apt' resolver is currently the default, and
recommended for most users. This resolver uses apt-get to resolve dependencies. Alternative
resolvers are 'apt', 'aptitude' and 'aspcud'. The 'apt' resolver uses a built-in resolver module
while the 'aptitude' resolver uses aptitude to resolve build dependencies. The aptitude resolver
is similar to apt, but is useful in more complex situations, such as where multiple distributions
are required, for example when building from experimental, where packages are needed from both
unstable and experimental, but defaulting to unstable. If the dependency situation is too complex
for either apt or aptitude to solve it, you can use the 'aspcud' resolver which is a real SAT
solver and will thus alwyas find a solution if a solution exists.
Default:
$build_dep_resolver = 'apt';
RESOLVE_ALTERNATIVES
BOOL type. Should the dependency resolver use alternatives in Build-Depends, Build-Depends-Arch
and Build-Depends-Indep? By default, using 'apt' resolver, only the first alternative will be
used; all other alternatives will be removed. When using the 'aptitude' resolver, it will default
to using all alternatives. Note that this does not include architecture-specific alternatives,
which are reduced to the build architecture prior to alternatives removal. This should be left
disabled when building for unstable; it may be useful when building for experimental or backports.
Set to undef to use the default, 1 to enable, or 0 to disable. Example:
$resolve_alternatives = 0;
Default:
$resolve_alternatives = undef;
SBUILD_BUILD_DEPENDS_PUBLIC_KEY
STRING type. GPG public key for temporary local apt archive.
Default:
$sbuild_build_depends_public_key = '/var/lib/sbuild/apt-keys/sbuild-key.pub';
SBUILD_BUILD_DEPENDS_SECRET_KEY
STRING type. GPG secret key for temporary local apt archive.
Default:
$sbuild_build_depends_secret_key = '/var/lib/sbuild/apt-keys/sbuild-key.sec';
Logging options

BOOL type. Should build log mails be compressed?
Default:
$compress_build_log_mails = 1;

Default:
$debug = 0;
LOG_COLOUR
BOOL type. Colour log messages such as critical failures, warnings and success
Default:
$log_colour = 1;
LOG_DIR
STRING type. Directory for storing build logs. This defaults to '.' when SBUILD_MODE is set to
'user' (the default), and to '$HOME/logs' when SBUILD_MODE is set to 'buildd'.
Default:
$log_dir = undef;
LOG_FILTER
BOOL type. Filter variable strings from log messages such as the chroot name and build directory
Default:
$log_filter = 1;

STRING type. email address set in the From line of build logs
Default:
$mailfrom = 'Source Builder <sbuild>';
MAILTO STRING type. email address to mail build logs to
Default:
$mailto = '';
MAILTO_HASH
HASH:STRING type. Like MAILTO, but per-distribution. This is a hashref mapping distribution name
to MAILTO. Note that for backward compatibility, this is also settable using the hash %mailto
(deprecated), rather than a hash reference.
Default:
$mailto_hash = {};
MIME_BUILD_LOG_MAILS
BOOL type. Should build log mails be MIME encoded?
Default:
$mime_build_log_mails = 1;
VERBOSE
NUMERIC type. Verbose logging level
Default:
$verbose = 0;
Maintainer options
KEY_ID STRING type. Key ID to use in .changes for the current upload. It overrides both
$maintainer_name and $uploader_name.
Default:
$key_id = undef;
MAINTAINER_NAME
STRING type. Name to use as override in .changes files for the Maintainer field. The Maintainer
field will not be overridden unless set here.
Default:
$maintainer_name = undef;
UPLOADER_NAME
STRING type. Name to use as override in .changes file for the Changed-By: field.
Default:
$uploader_name = undef;

CROSSBUILD_CORE_DEPENDS
HASH:ARRAY:STRING type. Per-architecture dependencies required for cross-building. By default, if
a Debian architecture is not found as a key in this hash, the package crossbuild-
essential-${hostarch}:native will be installed. Example:
$crossbuild_core_depends = {
nios2 => ['crossbuild-essential-nios2:native', 'special-package'],
musl-linux-mips => ['crossbuild-essential-musl-linux-mips:native', 'super-special'],
