Subject: Re: [OMPI users] Creating 64-bit objects?

Does the same issue occur in OMPI 1.5?

Should we put in a local patch for OMPI 1.4.x and/or OMPI 1.5? (we've done this before while waiting for upstream Libtool patches to be released, etc.)

After looking at <topdir>/ompi/mpi/f90/Makefile, I see that FCFLAGS shows up in link lines (“libmpi_f90_la_LINK” and “FCLINK”). This direction seems to come from Makefile.in.
