Subject: Re: [OMPI users] PGI Fortran pthread support
From: Gus Correa (gus_at_[hidden])

Hi Orion

That's exactly what happened to me.
Configured OK, failed on make because of "-pthread".
See my message from a minute ago, and this thread,
for a workaround suggested by Jeff Squyres,
of stripping off "-phtread" from the pgf90 flags:

There is a little script in the above message to do the job.

I hope it helps.
