The error about not finding shared libraries can be fixed by adding the proper path to LD_LIBRARY_PATH, which Ralph has already mentioned. If Open MPI is installed in $HOME/openmpi, LD_LIBRARY_PATH needs to be set like this:
export LD_LIBRARY_PATH=$HOME/openmpi/lib:$LD_LIBRARY_PATH The mpi libraries are not in the base install directory, but in a lib directory inside the installation directory.

You installed OMPI into $HOME/openmpi, so you should have done: PATH=$HOME/openmpi/bin:$PATH LD_LIBRARY_PATH=$HOME/openmpi/lib:$LD_LIBRARY_PATH Ralph On Jan 23, 2019, at 6:36 AM, Serdar Hiçdurmaz <hicdurmazser...@gmail.com<mailto:hicdurmazser...@gmail.com>> wrote: Hi All, I try to install Open MPI, which is prerequiste for liggghts (DEM software).
