[Dune] Identifying MPICH during configure

[Eike Mueller]

Hi Steffen and Markus,

thanks a lot, I looked at the mpi.h on my system and it indeed looks like it's MPICH 3.0 (there's a #define MPICH_VERSION "3.0.3"). Yes, I'm using version 2.2.1 of DUNE.

As for UG, I was also using a slightly older version (patched with patch10-rc4), so I have now updated this with the latest patch as well, which fixes the problem there, I can configure, compile and install UG Grid with this.

I also downloaded the 2.2.1 tarball of DUNE again and successfully applied the patch you describe for m4/mpi-config.m4. Unfortunately that does not seem to help, and I suspect this is because the tarball contains aclocal.m4, which does not contain the test_mpich3() marco. I don't know much about autotools, but when I try to delete aclocal.m4 and regenerate it with aclocal I run into a different problem:

eike at eslogin004 $ aclocal
configure.ac:6: error: m4_defn: undefined macro: _m4_divert_diversion
configure.ac:6: the top level
autom4te: /usr/bin/m4 failed with exit status: 1
aclocal: autom4te failed with exit status: 1

Apart from this, just looking through the patch, running ./conftest in mpi_trybuild_run() might not work as the MPI compiler is configued to cross-compile for the compute nodes, so I'm not sure I can execute anything on the login nodes, but I will find out once the configure runs.

Thanks,

Eike
