Bug 284538 – x11-drivers/nvidia-drivers-185.18.{14,31} fail to compile on 2.6.31

• Status: RESOLVED WONTFIX
• Product: Gentoo Linux

[Description Florian Streibelt 2009-09-10 22:51:35 UTC]

When updating to 2.6.31 the nvidia-drivers will not compile any more due to a missing member in a struct in the kernel.
As soon as /usr/src/linux is linked egains 2.6.31 it will fail.

Reproducible: Always

Steps to Reproduce:
1. update kernel
2. emerge nvidia-drivers to get X
3. boom

Actual Results:

this patch is working for 2.6.31-gentoo - but breaks compiling on older kernels (as expected)

Assumes the fedora patch file is in files

[Comment 4 Michal Januszewski (RETIRED) 2009-09-26 18:51:58 UTC]

The Gentoo developers have a policy of not patching the kernel part of the NVIDIA drivers for compatibility with newer kernel versions.  Feel free to use one of the currently masked nvidia-drivers releases (190.*) which compile just fine with 2.6.31.
