Dear Firedrake developers, I'm trying to install Firedrake with the install script on CentOS Linux release 7.3.1611. I'm doing a "firedrake-install --no_package_manager --disable-ssh". The script fails when building pyop2/sparsity.cpp, because it did not find mpi.h. I notice that it uses gcc for compiling while it should use the appropriate MPI Wrapper function mpicxx. There are environment variables available in my system ($MPICC, $MPICXX, $MPIFC) pointing to the appropriate MPI Wrappers (mpicc, mpicxx, mpif90). How do I tell the install script to use these? I notice the option "--mpicc" for the C compiler, but how do I set the C++ (and Fortran) compiler? Thank you! Henrik -- Dipl.-Math.
