Subject: Re: [OMPI users] Problem building OpenMPI with PGI compilers
From: Gus Correa (gus_at_[hidden])

Hi David

Last I tried, OpenMPI 1.3.2, PGI (8.0-4) was problematic,
particularly for C and C++.

I eventually settled down with a hybrid gcc, g++, and pgf90
(for both OpenMPI F77 and F90 bindings).
Even this required a trick to avoid the "-pthread" flag
to be inserted among the pgf90 flags (where it doesn't belong).
Yes, libtool was also part of the problem back then.
You may find my postings about on this list archives - early 2009 -,
along with Jeff Squyres' solution for the problem.

I also built a full Gnu version (gcc, g++, gfortran, gfortran)
of OpenMPI that works well.
Intel and hybrid Gnu(gcc,g++)+Intel(ifort for F77 and F90)
versions of OpenMPI also work right.
We need multiple compiler support here anyway.
