<p class="MsoNormal">I’m trying to troubleshoot a compilation problem on our Cray XE6. The code seems to compile following the instructions given in the README, but fails to link with the MPI libraries as far as I can see. We are getting undefined reference
errors that seem to indicate at least a library path problem, but may be more involved. Our efforts thus far have included setting environment variables as described in the README file, and swapping compiler and open_mpi versions. Here is a excerpt from the
compile log where things start to go wrong. Please take a look and reply if you can help us.<o:p></o:p></p>
