In the spec file debuginfos are destroyed with # build openmpi version cp -rp src.orig src %{_openmpi_load} %dobuild %{_openmpi_unload} rm -rf src Debuginfos should be kept for all binaries. The right way to do this is to use separate build directories for all the different flavors. Please don't break the debuginfos.
The line 255 of http://pkgs.fedoraproject.org/cgit/nwchem.git/tree/nwchem.spec says that the last build src dir is kept. I understand that debuginfo is extracted from the installed binaries at the end of %install and see nwchem-debuginfo at http://koji.fedoraproject.org/koji/buildinfo?buildID=700515 What else is missing?
Well, I guess that might work...
