FWIW: I compile with PGI 7.1.4 regularly on RHEL4U4 and don't see this
problem. It would be interesting to see the config.log's from these
builds to see the actual details of what went wrong.

Hi,
I've been attempting to build Open MPI 1.2.6 using a variety of
compilers including, but not limited to, PGI 7.1-6 and Sun Studio 12
(200709) on a CentOS 5.2 32-bit Intel box.
Building against either of the above compilers results in the
following message produced by configure:
************************************************************************
Open MPI was unable to find threading support on your system. In the
near future, the OMPI development team is considering requiring
threading support for proper OMPI execution. This is in part because
we are not aware of any users that do not have thread support - so we
need you to e-mail us at o...@ompi-mpi.org and let us know about this
problem.
************************************************************************
I don't see this when building against the Intel 10.1.015 or GNU GCC
4.1.2 compilers. I cannot see any answer to this in the FAQ or list
archives.
I've attached files showing the output of configure and my
environment to this message.
Is this expected?
Thanks,
Mark
