BUILD-RDEPS(1)                                                  BUILD-RDEPS(1)

NAME
       build-rdeps - find packages that depend on a specific package to build
       (reverse build depends)

SYNOPSIS
       build-rdeps package

DESCRIPTION
       build-rdeps searches for all packages that build-depend on the
       specified package.

       The default behaviour is to just `grep` for the given dependency in the
       Build-Depends field of apt's Sources files.

       If the package dose-extra >= 4.0 is installed, then a more complete
       reverse build dependency computation is carried out. In particular,
       with that package installed, build-rdeps will find transitive reverse
       dependencies, respect architecture and build profile restrictions, take
       Provides relationships, Conflicts, Pre-Depends, Build-Depends-Arch and
       versioned dependencies into account and correctly resolve multiarch
       relationships for crossbuild reverse dependency resolution.  (This
       tends to be a slow process due to the complexity of the package
       interdependencies.)

OPTIONS
       -u, --update
           Run apt-get update before searching for build-depends.

       -s, --sudo
           Use sudo when running apt-get update. Has no effect if -u is
           omitted.

       --distribution
           Select another distribution, which is searched for build-depends.

       --only-main
           Ignore contrib and non-free

       --exclude-component
           Ignore the given component (e.g. main, contrib, non-free).

       --origin
           Restrict the search to only the specified origin (such as
           "Debian").

       -m, --print-maintainer
           Print the value of the maintainer field for each package.

       --host-arch
           Explicitly set the host architecture. The default is the value of
           `dpkg-architecture -qDEB_HOST_ARCH`. This option only works if
           dose-extra >= 4.0 is installed.

       --old
           Force the old simple behaviour without dose-ceve support even if
           dose-extra >= 4.0 is installed.  (This tends to be faster.)

           Notice, that the old behaviour only finds direct dependencies,
           ignores virtual dependencies, does not find transitive dependencies
           and does not take version relationships, architecture restrictions,
           build profiles or multiarch relationships into account.

       --build-arch
           Explicitly set the build architecture. The default is the value of
           `dpkg-architecture -qDEB_BUILD_ARCH`. This option only works if
           dose-extra >= 4.0 is installed.

       --quiet
           Don't print meta information (header, counter). Making it easier to
           use in scripts.

       -d, --debug
           Run the debug mode

       --help
           Show the usage information.

       --version
           Show the version information.

REQUIREMENTS
       The tool requires apt Sources files to be around for the checked
       components.  In the default case this means that in /var/lib/apt/lists
       files need to be around for main, contrib and non-free.

       In practice this means one needs to add one deb-src line for each
       component, e.g.

       deb-src http://<mirror>/debian <dist> main contrib non-free

       and run apt-get update afterwards or use the update option of this
       tool.
