[gentoo-user] nvidia-drivers-340.76 failed with gentoo-sources-4.0.5

[Jacques Montier]

Hi all,

Because of an old graphic card, i have to compile nvidia-drivers-340.76.
nvidia-drivers-340.76 does not compile with the new 4.0.5 kernel.
Here is the output error :
/var/tmp/portage/x11-drivers/nvidia-drivers-340.76/work/kernel/nv-pat.o]
Error 1

I saw a topic about that problem on Gentoo forum :
https://forums.gentoo.org/viewtopic-p-7754020.html?sid=3b9fed3069c0b6644c1a41e839455b85
I tried to apply the patch
/etc/portage/patches/x11-drivers/nvidia-drivers/nvidia-drivers-340.76.patch

This patch does not work ; i get the error
