Related question: If I am understanding PGI's list of fixed-TPRs (bugs) then it looks like one (certainly not the only) difference between 13.x and 14.1 is a fix to a problem with PROCEDURE and zero-argument subroutines. As it happens, the configure probe for PROCEEDURE is a zero-argument subroutine, but the "real" usage in OMPI is *not* zero-argument. This opens the possibility (not certainty) that PROCEDURE may work as required in PGI-13.x, in which case only a "more accurate" configure test would be required to restore F08 support for PGI-13 (present in 1.8.1 and lacking in 1.8.2rc2).
So, the most important question first: Does anybody care about PGI-13 (cannot use PGI-14 for some reason other than cost of license)? -Paul On Thu, Jul 31, 2014 at 6:17 PM, Jeff Squyres (jsquyres) <jsquy...@cisco.com > wrote: > Many thanks guys, this thread was most helpful in finding the fix. > > Paul H. nailed 80% of it on the head in the post where he identified the > Makefile.am change.
