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. http://www.open-mpi.org/faq/?category=mpi-apps#general-build http://www.open-mpi.org/faq/?category=mpi-apps#cant-use-wrappers -- Jeff Squyres jsquy...@cisco.com For corporate legal information go to: http://www.cisco.com/web/about/doing_business/legal/cri/
