Gilles,
Just as you speculate, PGI is creating a _-suffixed reference to the module
name:
$ pgf90 -c test.f90
$ nm -u test.o | grep f08
U mpi_f08_sizeof_
U mpi_f08_sizeof_mpi_sizeof_real_s_4_
You suggested the following work-around in a previous email:
$ INST/bin/mpifort ../test.f
./BLD/ompi/mpi/fortran/use-mpi-f08/.libs/libforce_usempif08_internal_modules_to_be_built.a
That works fine. That doesn't surprise me, because I had already
identified that file as having been removed from libmpi_usempif08.so
between 1.8.1 and 1.8.2rc2. It includes the symbol for the module names
plus trailing '_'.
