dpkg-buildpackage

SYNOPSIS
       dpkg-buildpackage [options]

DESCRIPTION
       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 VARIABLES).

       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
          specified).

       4. It  calls  dpkg-source  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-
          fied).

       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.

OPTIONS
       -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.

       --target=target
       --target target
       -Ttarget
       -sd
       -vversion
       -Cchangesdescription
       -mmaintaineraddress
       -emaintaineraddress
              Passed unchanged to dpkg-genchanges. See its manual page.

       -aarchitecture
              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.

              If the host architecture differs from the build architecture (as
              is the case for a cross-compilation),  and  if  the  environment
              variable PKG_CONFIG_LIBDIR is not set, then it is set to a value
              suitable for  cross-compilation  ("/usr/gnu-system-type/lib/pkg-
              config/:/usr/share/pkgconfig").

       -tgnu-system-type
              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.

       -rgain-root-command
              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-

       -psign-command
              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.

       -kkey-id
              Specify a key-ID to use when signing packages.

       -us    Do not sign the source package.

       -uc    Do not sign the .changes file.

       -i[regexp]
       -I[pattern]
       -s[nsAkurKUR]
       -z, -Z
              Passed unchanged to dpkg-source. See its manual page.

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

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

       --version
              Show the version and exit.

ENVIRONMENT VARIABLES
   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.

   Compiler flags
       Some environment variables defining compiler and linker options are set
       to default values unless already present in the environment. Note  that
       this  mechanism  was only introduced in version 1.14.17 of dpkg-dev and
       not all rules files and build tools will honour these  variables,  yet.
       See https://wiki.ubuntu.com/DistCompilerFlags for the details.

       CFLAGS Optimization options which are passed to the Debian build system
              and can/should be overriden  by  the  package  build  if  needed
              (default  value:  -g  -O2,  or  -g -O0  if noopt is specified in
              DEB_BUILD_OPTIONS).  Overriding   options   can   be   used   to
              explicitely set a higher optimization level, or work around com-
              piler bugs, which only can be seen with some optimization levels
              (the last opt level "wins").


       FFLAGS_APPEND
              Same as CFLAGS_APPEND for Fortran sources.

       CPPFLAGS
              Preprocessor  flags  which are passed to the Debian build system
              and can/should be overriden  by  the  package  build  if  needed
              (default:  empty). This macro is seldom used (most build systems
              just use CFLAGS instead of CPPFLAGS).

       CPPFLAGS_APPEND
              Preprocessor flags appended to  the  preprocessor  flags,  which
              must  not be overwritten by the package (mostly used to for test
              builds). Default value: empty.

       LDFLAGS
              Options passed to  the  compiler  when  linking  executables  or
              shared objects (if the linker is called directly, then -Wl and ,
              have to be stripped from these options). Default value: empty.

       LDFLAGS_APPEND
              Optimization options appended to the compiler flags when linking
              code,  which must not be overwritten by the package (mostly used
              to for test builds). Default value: empty.

       DEB_BUILD_OPTIONS
              As indicated above, noopt will  disable  optimation.   Addition-
              ally,  when  used with the hardening-wrapper package, the values
              hardening and nohardening will be converted into  their  respec-
              tive  DEB_BUILD_HARDENING values.  The hardening option can also
              include (optionally  prefixed  with  no  )  the  following  sub-
              options:  stackprotector  format  fortify pie relro For example,
              DEB_BUILD_OPTIONS=hardening=nopie would cause  DEB_BUILD_HARDEN-
              ING_PIE=0  to  be  set,  or  DEB_BUILD_OPTIONS=nohardening would
              cause     DEB_BUILD_HARDENING=0     to     be     set.       See
              http://wiki.debian.org/Hardening for further details.

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