Subject: Re: [OMPI users] unresolvable R_X86_64_64 relocation against symbol `mpi_fortran_*
From: Dmitry N. Mikushin (maemarcus_at_[hidden])

Compile and link - yes, but it turns out there was some unnoticed
compilation error because

./hellompi: error while loading shared libraries: libmpi_f77.so.1:
cannot open shared object file: No such file or directory

and this library does not exist.

Hm.
