Hello again, I think there were some typo in the patch line. I downloaded a tar.gz patch archive from gentoo forum : http://dev.gentoo.org/~gienah/unsupported/etc-portage-patches-x11-drivers-nvidia-drivers-340.76-for-kernel-gt-3.14.tar.gz Now nvidia-drivers compiles fine and everything is ok. Sorry for the noise, Cheers, *--* *Jacques*
