Subject: Re: [OMPI users] MPI on MacOS Lion help
From: Charles Shelor (cfshelor_at_[hidden])
Date: 2011-11-04 19:09:58


I just checked my laptop (also running Lion) and I do have gcc at /usr/bin and it is linked to /usr/bin/gcc-4.2. I just checked again on my Mac Pro and there is no gcc in /usr/bin although there is a /usr/bin/gcc-3.3, probably left over from an earlier OS or Xcode. I downloaded and installed Xcode 4.2 and that returned gcc to /usr/lib. I successfully ran

Now Xcode 4.2 does not recognize: #include <openmp>

I know this is an MPI forum rather than OpenMP, but I was wondering if anyone knew how to get OpenMP working in Xcode 4.2. The statement worked fine in Xcode 3.6.x

Thanks again for the help!

Charles
