Passant, unless this is a copy paste error, the last error message reads plus zero three, which is clearly an unknown switch (plus uppercase o three is a known one)
At the end of the configure, make sure Fortran bindings are generated. If the link error persists, you can ldd /.../libmpi_mpifh.so | grep igatherv and confirm the symbol does indeed exists Cheers, Gilles On Tue, Jan 19, 2021 at 7:39 PM Passant A.
