Description Dmitriy Vilkov 2011-08-29 12:45:33 UTC

Nvidia drivers won't compile under GCC 4.5.3-r1 with sys-kernel/pf-sources-3.0.2 kernel.

Reproducible: Always

sys-kernel/pf-sources overlay

This is an overlay with patch to the kernel sys-kernel/pf-sources-3.0.2 that fixes the bug.

That's not a patch.

Please describe the build error, attach the build log, and post your `emerge --info' output.

Also, do not attach tarballs with complete solutions, but supply the actual patch that humans can read and that does exactly what you describe.

Comment 4 Dmitriy Vilkov 2011-09-02 09:56:46 UTC

This overlay contains only a patch. I did it for people who don't like to wait a patch in the main stream.
And this patch do exactly what I described.
If you would look into this patch you will see that only one string has changed in the kernel sources. It's very trivial patch. But to get into this bug I've spent about 3 hours. It thus that at me the црщдуsystem is adjusted

Comment 5 Dmitriy Vilkov 2011-09-02 10:11:55 UTC

It thus that I have the whole (GCC, Kernel, etc) system set.
I just wanted to help you.
If you would like to reproduce the bug you will need to install GCC 4.5.3-r1, sys-kernel/pf-sources-3.0.2 or sys-kernel/pf-sources-3.0.1 and try to build the nvidia drivers. It won't compile without any messages. Then you need to go to nvidia sources and compile it manually after this you will get a message about sizeof unnamed structure or something like that i don't remember. Then just google this error message. And you will get info about some optimizations tricks in GCC because of it we have got this error.
