solution: nvidia driver + gcc 3.4

hello. I had a problem and found an odd solution that I wished to share (incase others were in my same position)- and possibly get insight on what's wrong? (Someone may have already posted this. If so, I apologize.)

My system is a 2ghz p4 running kernel version 2.6.7.

I had mistakenly unmerged nvidia-kernel, no biggy. I then 'emerge -uD world' and merged nvidia-kernel again. I found that nvidia.ko didn't work. The nvidia module was giving me an odd "invalid module format" error when I attempted to modprobe it and xorg said it couldn't load it.. hmm. In /var/log/messages I was seeing:

And does 3d work? If everything is ok, then you are right, it is as stupid as it looks.

The version magic errors are because the kernel and ALL modules need to be compiled with the same version of gcc. In your case when you did emerge -uD world you emerged a new version of gcc and in this situation should recompile the kernel.

Then it is strange that it works.

It's not strange, there had been no ABI changes between gcc-3.3 and 3.4 yet.
Anyway, your gcc got updated and you ought to recompile the kernel with it.

True. But even then nvidia-kernel-1.0.6111-r1 does not insert into a 2.6.9 kernel (using GCC 3.3.4). Everything works with 2.6.8 though. The error I get is:

dont use -r1 for vanilla kernels, use vanilla 1.0.6111

graadz · emerge =nvidia-kernel-1.0.6111

I am not using vanilla sources, I am using mm-sources. In anycase, found the solution here.

who's the chick in the picture ?
OH and I'm experiencing the same problems ?
I think a developer needs to take a look at this shite!

Get this, includes remap_pfn_range patch.
http://geki.ath.cx/nvidia-kernel-1.0.6111-r1.tar.bz2
(it got updated)
Works fine here with 2.6.9-rc3-mm1.

Another option: http://kernel.damouse.co.uk/nvidia-kernel-1.0.6111-r3.tar.bz2
(haven't tried that)

i saw both those earlier and I have not had success with either one. Oh yeah that's cause they give us files but don't tell us what to do with them.

there are instructions in this thread https://forums.gentoo.org/viewtopic.php?t=216985

you need to create a portage overlay directory so that you don't wipe out your changes at the next emerge sync

add the overlay directory to /etc/make.conf

download and extract one of the tarballs linked above to your overlay directory

create the digest then emerge /path/to/extracted/ebuild/in full

All of the code is in the link above on the 2nd page, see logic's post

The post from me a little further in this thread should solve your problem if you are running mm-sources. If you run GCC 3.4.2, then you might want to rebuild your kernel image, modules and re-merge nvidia-kernel...-r2 with GCC 3.3.4 and see if that will help.

same nothing like a middle eastern woman. Anyway I fixed the problem for me atleasat. I just downloaded the binary file right from NVIDIA. Then said no to the download a module for my kernel. Then told it to build a custom one for my kernel and it worked like a charm.
