Great point from David ! As a side note, you can configure --enable-mpirun-prefix-by-default ... && make install
If you choose to do so, you will not have to set LD_LIBRARY_PATH since it will be "built in" the Open MPI binaries/libraries (via the -rpath linker option) Cheers, Gilles On Sat, Jan 26, 2019 at 1:50 AM Shrader, David Lee via users <users@lists.open-mpi.org> wrote: > > The error about not finding shared libraries can be fixed by adding the > proper path to LD_LIBRARY_PATH, which Ralph has already mentioned.
