Your makefile does not indicate the location of mpif.h to your FORTRAN
compiler which in the case of —with-mpi=0 is in ${PETSC}/include/mpiuni
Note that if you simply copy a makefile from PETSc, say
src/ts/examples/tutorials/makefile and modify that slightly for you code you
don’t need to manage all the -I -L stuff yourself, our makefiles take care of
it and are portable for different MPIs etc.
