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.

--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.

--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.
