Better yet, the Open MPI team strongly discourages listing individual MPI libraries on the link line because we reserve the right to change them over time.
Instead, we *strongly* advise you to just use Open MPI's wrapper compilers, which will insert all the Right compiler and linker flags. Then you don't have to worry about any of those pesky -I and -L options, especially when transitioning between different MPI implementations and versions of Open MPI.
