I'm running an amd64~ system which is usually up to date. Yesterday after an emerge I had this message
Quote:
WARN: postinst
After an upgrade of PPL it is important that you rebuild
dev-libs/cloog-ppl.

If you use gcc-config to switch to an older compiler version than
the one PPL was built with, PPL must be rebuilt with that version.

In both cases failure to do this will get you this error when
graphite flags are used:

sorry, unimplemented: Graphite loop optimizations cannot be used


So I followed instructions and emerged cloog-ppl. Now almost nothing want to emerge and the error message is the one advertised as a possibility. A google search on this problem found an old post of mine http://forums.gentoo.org/viewtopic-p-6259809.html?sid=90e4008465ef9a7fd30b83b4ed86d7f. The solution there was to re-emerge perl. That fix is not possible in this case has an attempt to do this gives the same failure as almost everything else. Any idea? Thanks,
Fred

Problem fixed by removing
Quote:
-floop-interchange -floop-strip-mine -floop-block
from my CFLAGS, emerging ppl and cloog-ppl (the former may not have been necessary), and then restoring the old CLFAGS. (Thanks to a suggestion from moonbots at http://forums.gentoo.org/viewtopic.php?p=6540144#6540144)
