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  followed  by  fakeroot  debian/rules
          binary-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).

       6. It  calls  gpg  to  sign the .dsc file (if any, unless -us is speci-

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

       8. It calls gpg to sign the .changes file (unless -uc is specified).

       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.

       -F     Specifies a normal full build, binary and source  packages  will
              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.

       -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.

              When  dpkg-buildpackage  needs  to  execute  part  of  the build
              process as root, it prefixes the command it executes with  gain-
              root-command  if  one has been specified. Otherwise, if none has
              been specified, fakeroot will be used by default, if the command
              is  present.   gain-root-command should start with the name of a
              program on the PATH and will get as arguments the  name  of  the
              real  command  to  run  and the arguments it should take.  gain-
              root-command can include parameters (they  must  be  space-sepa-
              rated)  but  no  shell  metacharacters.  gain-root-command might
              typically be fakeroot, sudo, super or really.  su is  not  suit-

              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.

       -us    Do not sign the source package.

       -uc    Do not sign the .changes file.

       -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.

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

              Show the version and exit.

       Even  if  dpkg-buildpackage exports some variables, debian/rules should
       not rely on their presence and should instead use the respective inter-
       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
       The  CFLAGS,  CXXFLAGS,  FFLAGS, CPPFLAGS and LDFLAGS environment vari-
       ables are set to the values that dpkg-buildflags returned. See its man-
       ual page for more information.
