[SOLVED] [LFS-7.2] Fail to build Nvidia drivers

McZ · 05-17-2013, 01:42 PM

I am running LFS-7.2 on my sony vaio laptop. this far I have only used the built in GPU in my CPU, but I would like to test a bit of gaming with wine so I need my nvidia GPU to work.

I downloaded latest nvidia driver, but it complains that I don't have /lib/modules/3.7.1/build/include/linux/version.h

I have it in my older 3.5.2 kernel but that kernel didn't work any good with the internal gpu in my core i5 so I upgraded to 3.7.1

How can I get the version.h? I have extracted kernel src into /usr/src and built the kernel.

Well that would make sense... You changed your kernel without changing the linux headers (usually you shouldn't without a rebuild).

What you can try is to symlink /lib/modules/3.5.2 to /lib/modules/3.7.1

This should work if nothing in the kernel has changed dramatically, I think it would be safer to rebuild LFS but this might work with mixed results.

Again, this is dirty hack that cause system instability as well as miss up anything you build that requires kernel headers. USE AT YOUR OWN RISK!

EDIT: Disregard this, drunna is correct.

The /lib/modules/X.Y.Z directory is created and (partially) filled when compiling the kernel (this step: make modules_install). This is not about the headers in /usr/include.

How did you upgrade from kernel 3.5.2 to 3.7.1? Did you follow the procedure in the book (parts of chapter 8.3)?

Do you know about this document: NVIDIA Accelerated Linux Graphics Driver README and Installation Guide?

BTW: Maybe this blog article might help with your kernel: LFS: Building a kernel

I have had this trouble a number of times with the nvidia drivers, sometimes its just a case of grabbing the newest driver, this time I had to manually copy the version file and so on like so:

Code:

chown -R 0:0 .
	cp -r . $PKGTMP/$pkgname/usr/src/linux-3.8.0
	cp  $PKGTMP/$pkgname/usr/src/linux-3.8.0/usr/include/linux/version.h $PKGTMP/$pkgname/usr/src/linux-3.8.0/include/linux
	ln -sv ../../../usr/src/linux-3.8.0 $PKGTMP/$pkgname/lib/modules/3.8.0/build
	ln -sv ../../../usr/src/linux-3.8.0 $PKGTMP/$pkgname/lib/modules/3.8.0/source

Ignore the $PKGTMP/$pkgname bt as I use a package manager.
It seems that every nvidia driver install needs a bit of tweaking, oh the joys of LFS!

There are also some advanced features to the installer that allows you to set various directory's have a look at the help

Thanks for all answers. I found a solution from som Redhat forum I think it was. Anyway, the version.h is in the linux kernel src tree I just made a symlink to the place the driver is looking for it.

That solved the compiling problem. But then I found that I need to use "Bumblebee" because my laptop is running Nvidia optimus and Nvidias driver does not support that yet. So I stopped trying to get it work, rebooted Windows and played some Diablo 3

Anyway, I have LFS-7.3 ready in my Auto LFS repo. So I will rebuild LFS-7.3 before I get my hands dirty with Bumblebee and nvidia optimus, unless they release I driver that works before
