Need help with Nvidia-kernel

jumpinkiwi · 07-05-2003, 04:11 PM

I'm trying to install the tar.gz file for the Nvidia drivers and am getting this error message.

"You appear to be compiling the NVdriver kernel module with
a compiler different from the one that was used to compile
the running kernel. This may be perfectly fine, but there
are cases where this can lead to unexpected behaviour and
system crashes.

If you know what you are doing and want to override this
check, you can do so by setting IGNORE_CC_MISMATCH.

In any other case, set the CC environment variable to the
name of the compiler that was used to compile the kernel."

I'm running Knoppix 3.2 V06/06, Biostar M7NCD Pro With an AMD Athlon 2600 and cant even use my usb mouse or any port on the mobo.
Any ideas would be welcome

It would probably be better to compile a new kernel with the nvidia modules. But if the difference in the gcc versions is not in the major version, you'll probably be okay.

adz · 07-06-2003, 04:55 AM

OK. First, you'll want to find out which version of gcc you have. To do this type "cc --version". Then you'll want to find out which compiler was used to compile your kernel. To do this type "cat /proc/version". Note the two numbers. If they are reasonably similar (like 3.2 and 3.3 or something like that) then you set the IGNORE_CC_MISMATCH variable. To do this type "export IGNORE_CC_MISMATCH=1".

However, it is quite likely that the two versions will not be compatible. In that event, you have two options. Recompile your kernel with your version of gcc or try to find an older version of gcc (and set the CC variable).

To recompile your kernel, do the following:

*Make sure there is a symlink to your kernel source in /usr/src called linux. To do this type (whilst root and in /usr/src) "ln -s kernel-source-<version> linux". This will effectively create a directory called /usr/src/linux (where the "linux" part is a symlink).
*Go to /usr/src/linux and type "make oldconfig". This conserves your current kernel settings but lets you recompile the modules and such.
*Type "make dep". This handles dependencies and takes a little while.
*Type "make modules". This recompiles your modules and also takes a while.
*Type "make modules_install". This copies the previously made modules to the appropriate directory (/lib/modules/<kernel version>). I believe this step also generates a modversions.h file which the nvidia installer requires.
*Rerun the nvidia installer and all should be fine.

To get an older version of gcc under debian type "apt-get install gcc-<version>". I'm not sure about other distributions. You may be able to install the rpm (if it's available) and there *shouldn't* be any dependency problems. So, effectively you will have more than one version of gcc installed. Then you type "which gcc-version" to find out where the gcc package you just installed was put (probably /usr/bin) and the shove that information into the CC enviro variable. For example, under debian it would be "export CC=/usr/bin/gcc-<version>".

Oh just to make sure you know, in the above text, anywhere you see something like "<version>" you replace it by the appropriate version number (without the "<" and ">" signs.

Actually, I heard that knoppix could auto-install the nvidia drivers. No idea how, though. I'm just a plain old debian user.

ghostwalker · 07-06-2003, 10:09 PM

Go to NVidia site and download the linux .run file.

chmod +x *.run

./NVIDIA-Linux-x86-1.0-4363.run

Follow the directions and you are of an running....

adz · 07-06-2003, 11:58 PM

I believe he's already gotten that far. Otherwise he wouldn't have received that error.

Worked great for me!

I just installed a biostar nforce2 motherboard (although it is the igp version) and with Knoppix everything was working just fine (with the live cd).I can't vouch for the usb since I don't use it.
I slapped gentoo in there now and don't have a problem either.Anything but the LAN should be supported by a regular kernel.If you use a nvidia graphics card you need to get the drivers for it.

jumpinkiwi · 07-07-2003, 06:14 PM

I hate to ask such an easy question, and I've searched around the news groups but how....step by step do I go into xf86config and make sure the nvidia driver is selected and not the nv driver?

AJ

I will not be beaten

crashmeister · 07-07-2003, 06:53 PM

All I did was to write configure with xf86config for vesa and then manually changed the vesa to nvidia in the device section.But you need to have the drivers installed for that plus I just installed a nvidia to dayfor the first time - it's not like I do know a lot about it.
But your USB mouse and nvidia graphics are two completely different things with different drivers.

adz · 07-08-2003, 01:29 AM

Jumpinkiwi,

you edit your /etc/X11/XF86Config-4 file (as root) with your favourite editor (emacs, nedit, nano, vi) and go to 'Section "Module"'. Comment out (put a "#" in front of) 'Load "GLcore"' and 'Load "dri"' while making sure that the line 'Load "glx"' is present. Then, go to 'Section "Device"' and change the line 'Driver "nv"' to 'Driver "nvidia"'. Also make sure that the driver nvidia.o is loaded by default on startup (ie make sure there is a line "nvidia" in the /etc/modules file.

jumpinkiwi · 07-09-2003, 06:41 PM

Adz
I tried your idea but got some errors as usual. It keeps saying "no rule to make oldconfig.
I also ran the installer and it failed because the modversions.h file is missing. So, I guess I need to know how to add that file or recompile my kernel. I followed your instructions to the letter but no go.
I hope you have more ideas.

AJ

footfrisbee · 07-10-2003, 04:48 AM

If the directory /usr/src/linux is empty, install either the "kernel-headers-x.x.xx" or the "kernel-source-x.x.xx" package. Replace x.x.xx with your current kernel version (`uname -r`). Then adz's instruction will work great.

adz · 07-10-2003, 09:01 PM

If you get an error like "no rule to make oldconfig" then you probably haven't got the kernel-source installed. Or, you're missing a package used to compile the kernel. The packages you'll need are: make, gcc, bin86, and libc6-dev (I think that's all).

My instructions were given based on the assumption that you had already downloaded the kernel source. If you download the kernel source, you'll need to build it at some stage ("make oldconfig" etc) because you'll be missing a modversions.h file. Otherwise you can download the kernel-headers package specific to your kernel (this will have a modversions.h file). Then you'll quite likely have to set the IGNORE_CC_MISMATCH variable or the CC variable as stated above. I'd probably recommend going the kernel-headers option first as it's probably easier. If you go the headers then you'll probably have to use the --kernel-include-path=<path> option when running the nvidia installer. Try it without first and if that fails try again with. For details on nvidia installer options run the installer with the command "sh *.run -A |more". The "-A" tells it to spit out every option it has and the "|more" tells it to stop and prompt you when you've reached the end of the page.

I take it devil slayer's instructions bombed out also...

adz · 07-10-2003, 09:05 PM

Oh, if you ever want to compile a new kernel for whatever reason, the easiest to follow instructions that I've found are at:
