[CIG-SEISMO] compilation error (configure: error: MPI header not found; try setting MPI_INC)

[James Wookey]

It looks like you are pointing at the file specifically, not the directory which contains it. I think MPI_INC should be the directory containing mpi.h, i.e.:

./configure FC=gfortran MPIFC=mpif90 MPI_INC=/usr/include/mpich
