Subject: Re: [OMPI users] fortran90 and c++ wrappers don't work

Can you double check that you are using the wrapper compilers from the
Open MPI installation that you think you're using?

Tiger doesn't ship with Open MPI, so you shouldn't have problems
conflicting with a system-installed OMPI, but could you possibly have
another OMPI install hanging around somewhere?

What is the output of mpicc --showme, mpicxx --showme, mpif77 -showme,
and mpif90 --showme?

If the intel compilers are not defaulting to 64 bit, you might also
need to add -m64 to your wrapper compiler command line, e.g.:

shell$ mpif90 hello_f90.f90 -m64

You can add flags to the wrapper compilers with the following:

   --with-wrapper-cflags Extra flags to add to CFLAGS when using mpicc
   --with-wrapper-cxxflags Extra flags to add to CXXFLAGS when using
   --with-wrapper-fflags Extra flags to add to FFLAGS when using
   --with-wrapper-fcflags Extra flags to add to FCFLAGS when using
   --with-wrapper-ldflags Extra flags to add to LDFLAGS when using
   --with-wrapper-libs Extra flags to add to LIBS when using wrapper

Or you can edit the text files in $prefix/share/openmpi/*-wrapper-
