Nvidia Driver can't find kernel source

Forezt · 04-09-2004, 02:15 PM

I was trying to install the Nvidia driver on my computer using these instructions, but when I got into the installer and accepted the agreement, it said that it couldn't find a "precompiled kernel interface". I installed the kernel sources for my kernel. Could it be that it is looking in the wrong path? if so, how do I change the path it is looking in?

here is my nvidia-installer.log:

   this means that the installer will need to compile a kernel interface for
   your kernel.

       files are installed, you may specify the kernel source path with the
       '--kernel-source-path' commandline option.

You kernel sources are probably installed in /usr/src/linux-<kernel-version>.
Creating a symbolic link to i called linux should solve it, e.g:

/usr/src$ ln -s linux-2.6.3 linux

I did that just now and I'm still getting the same error. Is there some sort of way to tell it where the source code is?

I'm pretty sure I got the right source for my kernal, but I could double check.

i have installed pcq linux 2004 which is a linux distro based on fedora 1.
i tried to install nvidia video drivers but i got the error message that a pre compiled kernel interface was not found.please help

The precompiled interface is not a problem, simply following the prompt and let the installer compile one for your system (you will need to have the kernel sources installed).

As for the above issue with the kernel sources...
The typical sources setup for Fedora (Red Hat as well, naturally) is to have the sources installed to /usr/src/linux-<kernelversion> (where the <kernelversion> part would be replaced by the output of uname -r). The symlink mentioned (/usr/src/linux) should be there but is not crucial. The one that is crucial is found in the /lib/modules directory for the running (or compilation target) kernel.
You should find that the 'target' of the symlink /lib/modules/<kernelversion>/build points to the correct kernel sources tree, in this case /usr/src/linux-<kernelversion>.

As a specific example:
/lib/modules/2.6.4-1.305/build -> /usr/src/linux-2.6.4-1.305

The kernel-source rpm should have taken care of this for you.. so it is possible you have the wrong source rpm installed. What is the output (the complete output) of rpm -q kernel kernel-source?

kernel-2.4.22-1.2115.nptl
kernel-2.4.22-1.2174.nptl
kernel-source-2.4.22-1.2174.nptl_37.rhfc1.at

I am using kernel-2.4.22-1.2115.nptl I think. That's the option I select at startup in GRUB.

This is the wrong source rpm for the 2174 kernel, it is distributed from the ATRPMS repository, and although it might have the correct sourcecode.. it still is not the correct matching (and official) source.
If you wish to use this kernel you should remove that kernel source (rpm -e kernel-source) then download and install: http://mirrors.kernel.org/fedora.us/....nptl.i386.rpm

If you are running the 2115 kernel, then you will have to install the 2115 kernel-source before the driver can compile for it, these have to match precisely, having one kernel-source is not good enough.
Download and install: http://mirrors.kernel.org/fedora.us/....nptl.i386.rpm

It would be better to install the latest kernel than to use either of these old kernels... they are updated for a reason.

otoh Livna is back up with a mirror and you can use yum to get a pre-compiled nvidia rpm for your kernel version.
See http://livna.cat.pdx.edu/ for info.

When I try to remove my current kernel-source package, it says:

Code:

[root@localhost root]# rpm -e kernel-source
warning: cannot get shared lock on /var/lib/rpm/Packages

LordMorgul · 04-20-2004, 07:35 PM

This is an indication that you have another rpm process running (or yum / apt, which are using librpm). If you do not.. and you are certain of this then you may need to remove old, stale, lock files in /var/lock/rpm.
