Ok, so your MPI fortran library is compiled with one happened
underscore. So, my first guess was wrong : the compilation of ABINIT
doesn't raise a problem of underscore in symbols. If I read your first
post, the error was:
mpi_wtime_ symbol unresolved.
Is this symbol present in your libfmpich.a? Is it defined with a W or a
T?

Ok, but I think this corrects the first problem by chance, because this
symbol exists in the C library file... So I was wrong, don't use -assume
nounderscore.

By the way, you should not have to specify the -L... and -lfmpi and
-lmpi, the mpif90 script should do it for you. Ideally, just use
'--enable-mpi FC=[...]/mpif90'.

Hope we can convergence, since it should work ;)
