[gentoo-user] nvidia-drivers fail to determine kernel version

[gentoo-user] nvidia-drivers fail to determine kernel version

[meino.cramer]

Hi,

when using vanilla kernel 3.7.5 (appropiate kernel headers installed)
emergeing nvidia-drivers 313.18 works fine.
As soon vanilla kernel 3.7.6 are installed the emerge process fails
because the kernel version couldnt be determined.

Both times /usr/src/linux symlinks to the according kernel sources.

What did I wrong? How can I fix that?

Thank you very much in advance for any help!
Best regards,
mcc

Note sure it's something wrong that you did, but that sure is strange... It
usually happens when switching from 3.x to 3.y kernel version...
When you're trying to emerge nvidia-drivers, are you running the recently
compiled kernel?

Hi Alexandre,

thanks for your reply! :)

Both kernels were compiled the same way prior to emergeing the
nvidia-drivers. In both cases the symlink /usr/src/linux points to
the correct kernel sources...
I also to booted into the kernel for which I want to emerge the
drivers which doesnt make a difference...

What else may be the reason for that?

Best regards,
mcc

Bug maybe?  I would search the forums then B.G.O. and see if it has been
reported there.

Hi,

It could be because it's hard coded in the nvidia sh script...
It used to be like that, don't know if it's still the case...

Every time Linus changes his underwear the nvidia installer forgets how
to find the kernel version :(   Rafaele Belardi posted a link here on
Jan 29 to a patch on the nvidia website.  If you can't make it work
I'll post more details tomorrow.

Hi,

thanks for your reply, walt! :)

What I found based on your mail are patches against different
nvidia-drivers and different kernel version than I am using to get
this running...
I tried the symlink include/linux -> include/uapi/linux mentioned
here:
https://devtalk.nvidia.com/default/topic/525935/linux/please-update-310-xx-drivers-for-linux-3-7-3-8-compatibility/2/
after the kernel was build, but ths doesnt help.

Any information would help me here a lot!

Thank you very much in advance for any help!
Best regards,
mcc

I can think of two (obnoxious) things I would try next:  first, install
both versions of the kernel sources and then use diff -r to find all
the changes in the 'include' subdirectory (that's always where nvidia
trips over its own feet) then look for the ones that nividia uses to
find the kernel version.

Second, I usually add 'set -x' near the top of the 'conftest.sh' script
that nvidia uses to find the kernel version, which results in a lot of
debugging info to be printed when the installer runs.  I edit the script
in /var/tmp/portage/xorg-drivers/nvidia-xxx/kernel/ after the installer
dies and then just type 'make module install' (which normally will do
what you want if/when the installer isn't broken).
