Subject: Re: [OMPI devel] Building Error
From: Matthew Russell (mrussel2_at_[hidden])

Hmm, I tried the recommendation above, adding -Wl,-search_paths_first, and I
still ran into the same issue. I suspect it is an issue with PGI.

Meanwhile, I've been able to get my applications (CMAQ) working with MPICH2,
so for now at least I am going to continue with that.

Thanks for the responses!
