Hi Ken,

it is not working this way.

This looks to be the problem. PROFILE_PRELIB needs to be added *before* libmpifort. Some time after 3.1, we re-organized which symbols go into which libraries and now libmpifort.so contains PMPI_Init and all its weak aliases (MPI_Init, mpi_init_, etc.) This means the MPI_Init symbol is resolved before your library is searched.

Can you manually try a compile line with -lfoo before -lmpifort and confirm that it works as expected? I.e.

gfortran fpi.f -I/homes/fisaila/software/mpich/include -I/homes/fisaila/software/mpich/include -L/homes/fisaila/software/mpich/lib -lfoo -lmpifort -Wl,-rpath -Wl,/homes/fisaila/software/mpich/lib -Wl,--enable-new-dtags -lmpi
