Paul and all, For what it's worth, with openmpi 1.8.2rc2 and the intel fortran compiler version 14.0.3.174 :
$ nm libmpi_usempif08.so| grep -i sizeof there is no such undefined symbol (mpi_f08_sizeof_) as a temporary workaround, did you try to force the linker use libforce_usempif08_internal_modules_to_be_built.a /* this library does not get installed (at least with intel compilers), but it is in the compilation tree */ Cheers, Gilles On 2014/07/31 12:53, Paul Hargrove wrote: > In 1.8.2rc2: > $ nm openmpi-1.8.2rc2-linux-x86_64-pgi-14.4/INST/lib/libmpi_usempif08.so | > grep ' mpi_f08_sizeof_' > U mpi_f08_sizeof_
