Subject: [OMPI users] Building OpenMPI 10.4 with PGI fortran 10.8 and gcc
From: Axel Schweiger (axel_at_[hidden])
Date: 2010-09-14 15:17:59


  Trying to build a hybrid OpenMPI with PGI fortran and gcc to support
WRF model
The problem appears to be due to a -pthread switch passed to pgfortran.

libtool: link: pgfortran -shared -fpic -Mnomain .libs/mpi.o
.libs/mpi_sizeof.o .libs/mpi_comm_spawn_multiple_f90.o
.libs/mpi_testall_f90.o .libs/mpi_testsome_f90.o .libs/mpi_waitall_f90.o

There has been discussion on this issue and the below solution
suggested. This doesn't appear to work for the 10.8
release.

There was a previous thread:
http://www.open-mpi.org/community/lists/users/2009/03/8687.php

suggesting other solutions.

Wondering if there is a better solution right now? Building 1.4.2

Thanks
