Testing the current v1.7 tarball (1.7.5a1r30634), I get a failure when building the oshmem examples. I've confirmed that the same problem exists on trunk (so not a problem with the CMR).

The relevant portion of "make" output in the example dir is shown above. Note that ring_usempi linked fine, indicating that F90 MPI bindings are fine. Additionally, ring_oshmem linked file, indicating that C language OSHMEM bindings are fine, too. In case it is relevant: this build is configured with --enable-static --enable-shared --enable-mpi-fortran=usempi --disable-vt The "--enable-static --enable-shared" flags are just to make for a more thorough test. However, retesting without --enable-static did not resolve the problem. The --enable-mpi-fortran flag is necessary because the F08 bindings don't build with this compiler ( http://www.open-mpi.org/community/lists/devel/2014/01/13802.php). The --disable-vt flag is necessary because the compiler crashes building VT.
