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, non-free and non-free-firmware.

       --only-devel
           Consider only development distributions (e.g. unstable, sid).

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

       --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.

       --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.

       --no-arch-all, --no-arch-any
           Ignore Build-Depends-Indep or Build-Depends-Arch while looking for reverse dependencies.

       --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.

       -q, --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,  non-free  and  non-free-
       firmware.

       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 non-free-firmware

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