[Cops] MPI and COPS

[Ted Ralphs]

The log file says it's failing because "linking to Fortran libraries 
from C fails." So the problem seems to lie with the C compiler. The MPI 
compilers are just wrappers around another C compiler (adding the right 
arguments to link to the MPI libraries). In this case, I think they are 
wrappers around gcc, which means you are probably not really using the 
portland group compilers unless someone implemented custom wrappers. It 
could be that you are somehow mixing Portland group libraries with gcc 
libraries. Can you do an "mpicc --version" and try to see what compiler 
you are using? Or just do "which mpicc" and look directly at the wrapper 
script. The next step would then be to look at the config.log from the 
successful serial build to see what compilers were used there. A 
possible solution would be just to use the same compilers for building 
the MPI code. See

http://www.open-mpi.org/faq/?category=mpi-apps#cant-use-wrappers

for instructions on that. You could also try configuring without 
specifying the MPI compiler name. I think configure will find it 
automatically. Sometime, there are multiple options. Perhaps you are 
using the wrong one. Well, that gives you a few things to try. Let me 
know how it goes.

Cheers,

Ted
