I recently needed to build an OpenMPI build on Power 8 where I had access to xlc / xlf
The current release fails (as noted in the readme) But a clone as of April 4th from git worked, here is my (simple) configure script: COMPILERS='CC=xlc FC=xlf CXX=xlc++' ./configure \ --prefix=$PREFIX \ --mandir=$PREFIX/man \ $COMPILERS Is there a better way to check other than make check It had not failures. xlc --version IBM XL C/C++ for Linux, V13.1.3 (5725-C73, 5765-J08) xlf -qversion IBM XL Fortran for Linux, V15.1.3 (5725-C75, 5765-J10) Version: 15.01.0003.0001 Thanks! -- Brock Palen www.umich.edu/~brockp Assoc.
