I second that. On more than one occasion, I spent weeks trying to get code to compile using the compilers on hand before giving up and spending $$ on a commercial compiler which compiled the code w/o any problems. In an ideal world, the code/Makefiles/configure scripts would written such that any standards-compliant compiler would work, but that's not always the case. -- Prentice _______________________________________________ Beowulf mailing list, Beowulf@beowulf.org sponsored by Penguin Computing To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
