Hi Marco,

This should not bee needed as DUNE should figure this out from MPICC

Please use the regular compiler here. But be sure that it is the same
that you compiled  mpi with, e.g.

To compile alugrid with the correct flags, I usually use some DUNE
magic, i.e. I use dune-common/bin/mpi-config to get the same flags as
used in DUNE:


./configure CC=$CC CXX=$CXX F77=$F77 --enable-static --disable-shared \
--prefix=/home/mblatt/src/dune/3rdParty/grids/alugrid52-install \
`/path/to/dune-common/bin/mpi-config --cflags --disable-cxx \
`/path/to//dune-common/bin/mpi-config --libs --disable-cxx \
--mpicc=$MPICC`" && make $MAKE_FLAGS clean install

BTW the --enabled-static --disable-shared is probably not needed and
not even wanted.

What is wrong with static libraries?

Do you need more support with DUNE or HPC in general?
