AUTOBUILDREQUIRES

NAME

autobuildrequires − Work out the BuildRequires of an RPM build automatically

SYNOPSIS

  auto−br−rpmbuild −ba foo.spec
  auto−br [build−command ...]

DESCRIPTION

Autobuildrequires analyzes an RPM package build to find out what BuildRequires lines it needs.

Instead of using "rpmbuild", use this command:

 auto−br−rpmbuild −ba foo.spec

(all the usual rpmbuild flags are supported). The command will build your package and then output a list of "BuildRequires" lines that it thinks your package needs.

If your build command is more complex and/or doesn’t use rpmbuild, then use:

 auto−br [build−command ...]

For example:

 auto−br make

HOW IT WORKS

The basic "magic" is a C "LD_PRELOAD" module, auto−buildrequires−preload.c, which intercepts some system calls to determine which files the build is looking at. Those get logged to a simple text file.

The Perl analysis script, auto−br−analyze.pl, runs afterwards on the logfile, and uses rpm to find out which packages those files belong to. Those are printed out as the list of BuildRequires.

A shell script, auto-br, brings the whole thing together.

EXIT STATUS

This program returns 0 if successful, or non-zero if there was an error.
