Subject: [OMPI users] Installing OpenMPI for Intel Fortran on OSX??
From: Goldstein, Bruce E (bruce.e.goldstein_at_[hidden])

I OSX 10.5, have Intel Fortran, but I do not have Intel C, so need to compile OpenMPI using gcc, which is supposed to work.
When I run the configure script I get an error message about
configure: error: C and Fortran 77 compilers are not link compatible. Can not continue.

I am guessing that the problem is that the Intel Fortran is compiling for a 64 bit architecture, and gcc is by default compiling for
32 bit. I tried setting an environment variable CFLAGS=-m64, but this did not help. I am really a novice at passing compiler
flags to things inside scripts, and also, not knowing these flags, and, also, maybe I tried to pass the wrong flag value. I would appreciate it
if anyone who knows what to do could provide a very specific recipe for exactly what I need to do to fix this problem.
Thanks very much. -bg
