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.

   -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.
