build-rdeps
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.
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.
-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.
