Usage: gdb_mbuild.sh [ <options> ... ] <srcdir> <builddir>
Options:
-j <makejobs> Run <makejobs> in parallel. Passed to make.
On a single cpu machine, 2 is recommended.
-k Keep going. Do not stop after the first build fails.
--keep Keep builds. Do not remove each build when finished.
-e <regexp> Regular expression for selecting the targets to build.
-f Force rebuild. Even rebuild previously built directories.
-v Be more (and more, and more) verbose.
Arguments:
<srcdir> Source code directory.
<builddir> Build directory.
Environment variables examined (with default if not defined):
