Sorry for the delay in replying.
Can you send your exact configure command line?
Also, do you need the F90 MPI bindings? If not, you can disable them
with the following:
--disable-mpi-f90

Dear OpenMPI pros.
I've got no answer, so let me try again.
I can't build OpenMPI 1.3 with a hybrid pgf90+gcc/g++ compiler set.
However, OpenMPI 1.2.8 builds correctly with the same compilers,
on the same computer (Linux x86_64 cluster), and same environment.
See details in my original message below.
The OpenMPI 1.3 build fails due to the (gcc) "-pthread" flag being
rejected by pgf90 during the libtool
link phase of libmpi_f90.so.0.0.0.
Since this flag was not present on the same spot on OMPI 1.2.8,
I wonder if the "-pthread" flag is really needed at that point,
or if inadvertently sneaked in the
OMPI 1.3 Makefiles and configure script.
These hybrid compiler builds of MPI often mean the difference
between being able to compile and run the very large
climate/ocean/atmosphere codes
which are at the core of our research mission here.
To my knowledge, this is not a unique situation,
and other people in our research field also need and use these
libraries built on "Gnu+commercial Fortran" compilers.
For this reason I keep a variety of OpenMPI, MPICH2, MVAPICH2
builds, and I try to stay current with the newest releases.
Any help is much appreciated.
Thank you,
Gus Correa
