dpkg-buildpackage - build binary or source packages from sources
is a program that automates the process of building a Debian package. It
consists of the following steps:
It prepares the build environment by setting various environment
variables (see ENVIRONMENT) and calls dpkg-source
--before-build (unless -T or --target has been used).
It checks that the build-dependencies and build-conflicts
are satisfied (unless -d is specified).
If a specific target has been selected with the -T or --target
option, it calls that target and stops here. Otherwise it calls
fakeroot debian/rules clean to clean the build-tree (unless
-nc is specified).
It calls dpkg-source -b to generate the source package (unless
a binary-only build has been requested with -b, -B or
It calls debian/rulesbuild followed by
fakeroot debian/rulesbinary-target (unless a source-only
build has been requested with -S). Note that binary-target is
either binary (default case, or if -b is specified)
or binary-arch (if -B is specified) or binary-indep
(if -A is specified).
It calls gpg to sign the .dsc file (if any, unless
-us is specified).
It calls dpkg-genchanges to generate a .changes file.
Many dpkg-buildpackage options are forwarded to

If -tc is specified, it will call fakeroot debian/rules clean
again. Finally it calls dpkg-source --after-build.
Specifies a binary-only build, no source files are to be built and/or
distributed. Passed to dpkg-genchanges.
Specifies a binary-only build, limited to architecture dependent packages.
Passed to dpkg-genchanges.
Specifies a binary-only build, limited to architecture independent
packages. Passed to dpkg-genchanges.
Specifies a source-only build, no binary packages need to be made.
Passed to dpkg-genchanges.
Specifies a normal full build, binary and source packages will be built.
This is the same as the default case when no build option is specified.
--target=target --target target -Ttarget
Calls debian/rulestarget after having setup the build
environment and stops the package build process here. If
--as-root is also given, then the command is executed
as root (see -r). Note that official targets that are required to
be run as root by the Debian policy do not need this option.
Only meaningful together with --target. Requires that the target be
run with root rights.
Passed unchanged to dpkg-genchanges. See its manual page.
Specify the Debian architecture we build for. The architecture of the
machine we build on is determined automatically, and is also the default
for the host machine.
Specify the GNU system type we build for. It can be used in place
of -a or as a complement to override the default GNU system type
of the target Debian architecture.
Number of jobs allowed to be run simultaneously, equivalent to the
option of the same name. Will add itself to the MAKEFLAGS
environment variable, which should cause all subsequent make
invocations to inherit the option. Also adds parallel=jobs
to the DEB_BUILD_OPTIONS environment variable which allows
debian/rules files to use this information for their own purposes.
The parallel=jobs in DEB_BUILD_OPTIONS environment variable
will override the -j value if this option is given.
Check build dependencies and conflicts; abort if unsatisfied. This is the

Do not clean the source tree (implies -b if nothing else has been
selected among -B, -A or -S).

fakeroot will be used by default, if the command is present.

is not suitable, since it can only invoke the user's shell with
instead of passing arguments individually to the command to be run.
Building a Debian package usually involves invoking
as a command with several standard parameters. With this option it's
possible to use another program invocation to build the package (it can
include space separated parameters).
Alternatively it can be used to execute the standard rules file with
another make program (for example by using
/usr/local/bin/make -f debian/rules
When dpkg-buildpackage needs to execute GPG or PGP to sign a source
control (.dsc) file or a .changes file it will run
sign-command (searching the PATH if necessary) instead of
gpg. sign-command will get all the arguments that
pgp would have gotten. If sign-command
takes its arguments in GPG rather than PGP style, you should give
the -sgpg option. sign-command
should not contain spaces or any other shell metacharacters.
Specify a key-ID to use when signing packages.
Do not sign the source package.
Do not sign the .changes file.
Passed unchanged to dpkg-source. See its manual page.
Pass option opt to dpkg-source.
Pass option opt to dpkg-genchanges.

Show the version and exit.
Even if dpkg-buildpackage export some variables, debian/rules
should not rely on their presence and should instead use the
respective interface to retrieve the needed values.
Variables set by dpkg-architecture
dpkg-architecture is called with the -a and -t
parameters forwarded. Any variable that is output by its -s
option is integrated in the build environment.
The CFLAGS, CXXFLAGS, FFLAGS, CPPFLAGS
and LDFLAGS environment variables are set to the values
that dpkg-buildflags returned. See its manual page for more
It should be possible to specify spaces and shell metacharacters in
and initial arguments for
gain-root-command and sign-command.
