[mpich-discuss] Cannot compile with debugging symbols

[Matthew Russell]

Hmm, to be honest, I've never debugged a program using MPI, so I'm not
completely sure what I need.  For a seg. fault. what would you suspect I
need?  The model runs on one processor without problems right now.

For your latter comment, I suspect you're right.  Right now I'm working on
building MPICH and the models I need to run with GNU compilers.

Thanks.
