dpkg-buildpackage [option...]

       dpkg-buildpackage is a program that automates the process of building a
       Debian package. It consists of the following steps:

       1. 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).

       2. It checks that the build-dependencies and build-conflicts are satis-
          fied (unless -d is specified).

       3. 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

       4. It calls dpkg-source -b to generate the  source  package  (unless  a
          binary-only build has been requested with -b, -B or -A).

       5. It calls debian/rules build-target followed by fakeroot debian/rules
          binary-target (unless a source-only build has  been  requested  with
          -S).  Note  that build-target and binary-target are either build and
          binary (default case, or if -b  is  specified),  or  build-arch  and
          binary-arch  (if  -B  is specified), or build-indep and binary-indep
          (if -A is specified).

       6. It calls gpg2 or gpg to sign the .dsc file (if any,  unless  -us  is
          specified or on UNRELEASED builds).

       7. It   calls  dpkg-genchanges  to  generate  a  .changes  file.   Many
          dpkg-buildpackage options are forwarded to dpkg-genchanges.

       8. It calls gpg2 or gpg to sign the .changes file (unless -uc is speci-
          fied or on UNRELEASED builds).

       9. If -tc is specified, it will call fakeroot debian/rules clean again.
          Finally it calls dpkg-source --after-build.

       -b     Specifies a binary-only build, no source files are to  be  built
              and/or distributed. Passed to dpkg-genchanges.

       -B     Specifies a binary-only build, limited to architecture dependent
              packages.  Passed to dpkg-genchanges.

       -A     Specifies a binary-only build, limited to architecture  indepen-
              dent packages. Passed to dpkg-genchanges.

       -S     Specifies  a  source-only  build,  no binary packages need to be
              made.  Passed to dpkg-genchanges.
              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  sys-
              tem type of the target Debian architecture.

              Specify  the  profile(s)  we  build,  as a comma-separated list,
              without the "profile." namespace prefix. The default behavior is
              to  build  for  no  specific profile. Also adds them (as a space
              separated list) to the DEB_BUILD_PROFILES  environment  variable
              which allows, for example, debian/rules files to use this infor-
              mation for conditional builds.

       -jjobs Number of jobs allowed to be run simultaneously,  equivalent  to
              the  make(1)  option  of  the  same name. Will add itself to the
              MAKEFLAGS environment variable, which should  cause  all  subse-
              quent  make  invocations to inherit the option. Also adds paral-
              lel=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.

       -D     Check  build  dependencies  and conflicts; abort if unsatisfied.
              This is the default behavior.

       -d     Do not check build dependencies and conflicts.

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

       -tc    Clean  the  source  tree  (using  gain-root-command debian/rules
              clean) after the package has been built.


              Building a Debian package usually involves invoking debian/rules
              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).   Alterna-
              tively  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 as rules-file).

              When  dpkg-buildpackage  needs  to  execute GPG to sign a source
              control (.dsc) file or a .changes file it will run  sign-command
              (searching  the PATH if necessary) instead of gpg2 or gpg. sign-
              command will get all the arguments that gpg2 or gpg  would  have
              gotten.  sign-command  should  not  contain  spaces or any other
              shell metacharacters.

              Specify a key-ID to use when signing packages.

       -us    Do not sign the source package.

       -uc    Do not sign the .changes file.

              Force the signing of the resulting files  (since  dpkg  1.17.0),
              regardless of -us or -uc or other internal heuristics.

       -z, -Z Passed unchanged to dpkg-source. See its manual page.

              Pass option opt to dpkg-source.

              Pass option opt to dpkg-genchanges.

       --admindir dir
              Change  the  location of the dpkg database. The default location
              is /var/lib/dpkg.

       -?, --help
              Show the usage message and exit.

              Show the version and exit.

              If set, it will be used to sign the  .changes  and  .dsc  files.

       face 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

   Compiler flags are no longer exported
       Between dpkg 1.14.17 and 1.16.1,  dpkg-buildpackage  exported  compiler
       flags  (CFLAGS,  CXXFLAGS, FFLAGS, CPPFLAGS and LDFLAGS) with values as
       returned by dpkg-buildflags. This is no longer the case.

   Default build targets
       dpkg-buildpackage is using the build-arch and build-indep targets since
       dpkg  1.16.2.  Those targets are thus mandatory. But to avoid breakages
       of existing packages, and ease the  transition,  it  will  fallback  to
       using the build target if make -f debian/rules -qn build-target returns
       2 as exit code.

       It should be possible to specify spaces and shell metacharacters in and
       initial arguments for gain-root-command and sign-command.
