27 Usage: gdb_mbuild.sh [ <options> ... ] <srcdir> <builddir>
29 -j <makejobs> Run <makejobs> in parallel. Passed to make.
30 On a single cpu machine, 2 is recommended.
31 -k Keep going. Do not stop after the first build fails.
32 --keep Keep builds. Do not remove each build when finished.
33 -e <regexp> Regular expression for selecting the targets to build.
34 -f Force rebuild. Even rebuild previously built directories.
35 -v Be more (and more, and more) verbose.
37 <srcdir> Source code directory.
38 <builddir> Build directory.
39 Environment variables examined (with default if not defined):
44 -b <maxbuilds> Run <maxbuild> builds in parallel.
45 On a single cpu machine, 1 is recommended.
