mk-build-deps - build a package satisfying a package's build-dependencies SYNOPSIS
mk-build-deps --help|--version mk-build-deps [options] control file | package name ... DESCRIPTION
Given a package name and/or control file, mk-build-deps will use equivs to generate a binary package which may be installed to satisfy all the build dependencies of the given package. If --build-dep and/or --build-indep are given, then the resulting binary package(s) will depend solely on the Build-Depends/Build-Depends-Indep dependencies, respectively. OPTIONS
-i, --install Install the generated packages and its build-dependencies. -t, --tool When installing the generated package use the specified tool. (default: apt-get --no-install-recommends) -r, --remove Remove the package file after installing it. Ignored if used without the --install switch. -a foo, --arch foo If the source package has architecture-specific build dependencies, produce a package for architecture foo, not for the system architecture. (If the source package does not have architecture-specific build dependencies, the package produced is always for the pseudo-architecture all.) -B, --build-dep Generate a package which only depends on the source package's Build-Depends dependencies. -A, --build-indep Generate a package which only depends on the source package's Build-Depends-Indep dependencies. -h, --help Show a summary of options. -v, --version Show version and copyright information. -s, --root-cmd Use the specified tool to gain root privileges before installing. Ignored if used without the --install switch. AUTHOR
