Description Peter Robinson 2011-06-16 09:03:42 UTC
mpich2 doesn't support the -m32 or -m64 gcc options so for %{arm} we need to either clear the setting or set it to something more appropriate for the platform so that it will compile.

the standard fedora cflags set -m32 and -m64 as appropriate, we should just patch out of mpich2 anything that tries to be too smart. and just rely on whats set by us.

One need to look closely at the spec and have some understanding of how mpich2 behaves to understand what the 'm_option' macros (that sets the -m32/-m64) does. That macro is NOT for setting the compiler flag in building the mpich2 library, but for specifying the basic flag the built mpi compiler should use (once installed).
