I've tried to compile libmesh in a Linux cluster, at the university I

I suppose the problem is ./configure doesn't find any synamic library
(libmpich++.so or something like that, just libmpich++.a), isn't it? But
I can't find any libmpich.so in the cluster. Just next files:
ls /opt/mpich/ch-p4/lib64/
libfmpich.a libmpichf90.a libpmpich.a libtvmpich.so.1
liblmpe.a libmpichf90nc.a libpmpich++.a libtvmpich.so.1.0
libmpe.a libmpichfarg.a libtmpe.a mpe_prof.o
libmpich.a libmpichfsup.a libtvmpich.so shared
Please, can you help me?
Can't help you with getting a libmpich++.so built; that's up to your
cluster admins.
If they balk and you're stuck having to build a statically-linking
libmesh.a, then as a workaround try building libMesh with
"METHOD=prof". Someone correct me if I'm wrong, but I think that
should give you a static library, so you'll at least be able to link
applications against non-PositionIndependentCode dependencies.
If you want a static libMesh library with all the debugging bells and
whistles and/or without profiling code generated, we don't have
anything like that right now, but if there's actually demand for it
we'd be happy to accept a patch (to compiler.m4 and Make.common.in
should be sufficient) adding such options.
