[Dune] Identifying MPICH during configure

[Eike Mueller]

Dear DUNE list,

I'm trying to install Dune and UG on Archer (the new UK HPC facility, 
replacing HECToR), and I noticed that it does not identify the MPI 
version (MPICH) correctly.

When I run ./configure in the UG directory, it basically claims that 
there is no MPI installed even though I clearly loaded the MPICH module 
(problem should be exactly the same in DUNE as the configure scripts 
seem to use the same mechanism for figuring out the MPI). I think this 
is because  the MPICH version is Cray specific, so current test always 
which preprocesses a simple c program and looks for MPICH specific test 
fails.

Instead of the current test for MPICH, wouldn't it be easier to do the 
same as what's done for identifying MPICH2 in the configure script, i.e. 
try to compile

#include <mpi.h>
#include <stdio.h>
int main() { printf ("%s\n", MPICH_VERSION); return 0; }

which will only work with MPICH? If I do this the configure script runs 
through and I can also compile UG successfully.

Thanks a lot,

Eike
