Back in Sep 2012 I reported that the trunk was broken with IBM's Fortran compilers. The last email I could find on that thread is http://www.open-mpi.org/community/lists/devel/2012/09/11519.php
Well, the errors with current 1.7 nightly tarball (1.7.4rc2r30303) may have changed slightly, but things are still quite broken. I've tested xlf-13.1 and 14.1 (correspond to xlc-11.1 and 12.1, respectively). The warnings and error from both versions look to be identical, though I've not checked too closely. I've attached relevant outputs from both builds. Warnings about command line options occur because "-D..." is *not* the right way to define preprocessor symbols with the XL fortran compilers. One must use "-WF,-D..." instead. There are warnings from mpi-ignore-tkr-interfaces.h which are all "modern fortran" stuff that means almost nothing to me. However, both finally die with: PPFC mpi-f08.lo /soft/compilers/ibmcmp-may2012/xlf/bg/14.1/bin/.orig/xlf90: 1501-216 (W) command option -_REENTRANT is not recognized - passed to ld "/home/hargrove/SCRATCH/OMPI/openmpi-1.7-latest-linux-ppc64-xlc-12.1/openmpi-1.7.4rc2r30303/ompi/mpi/fortran/use-mpi-f08/mpi-f08.F90", 1516-194 (S) A binding label must not be the same as the name of a program unit, common block, external procedure, and another binding label, ignoring differences in case.
