Richard Biener <rguenth at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |RESOLVED Resolution| |INVALID --- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> 2013-01-29 16:20:59 UTC --- "configure invokes gcc with --with-cloog-include=/usr/include/cloog-ppl" configure does no such thing - it's you providing that option. Simply don't (you need cloog-0.18.0, not cloog-ppl).
