Tim, a simple option is to configure ... LDFLAGS="-Wl,--enable-new-dtags" If Open MPI is built with this option, then LD_LIBRARY_PATH takes precedence over rpath (the default is the opposite as correctly pointed by Yossi in an earlier message) Are you sure about the default? I just did a default Open MPI v4.1.0 build on Linux with gcc 8.x: $ mpicc --showme gcc -I/home/jsquyres/bogus/include -pthread -Wl,-rpath -Wl,/home/jsquyres/bogus/lib -Wl,--enable-new-dtags -L/home/jsquyres/bogus/lib -lmpi -- Jeff Squyres jsquy...@cisco.com<mailto:jsquy...@cisco.com>
