Description

alugrid fails to build due to an '#error' statement in alu3dinclude.hh if HAVE_MPI_CPP is not defined.

With out further information it is not possible to use alugrid.

HAVE_MPI_CPP does not come from config.h neither does the header provide any further information on what is wrong. If HAVE_MPI_CPP test for what I assume (the existence of the c++ headers of mpi) this breaks with an (admittedly quite old) decission in Dune. We agreed to use only the C MPI interface due to the fact that we would need mpi libs for all different c++ compilers for hardly any advantages in the mpi interface.
