"CC version check failed" gcc 4.2.3 and gcc 4.1


Hi,

I am a beginner in Linux. I have Debian. I want to install the driver for my Asus notebook video card (GeForce 8400M GT). I have 4.2.3 gcc version installed but the kernel of the driver is compiled in gcc 4.1 It seems that the driver must be compiled with the same gcc version as the one from my computer so that can work. How can I make this driver compiled with gcc 4.1 to work on my computer. Do I have to install gcc 4.1 package ?


This is the lhe log file content:

he compiler used to build the running kernel.

If you know what you are doing and want to ignore the gcc version check, sel
ect "No" to continue installation. Otherwise, select "Yes" to abort install
ation, set the CC environment variable to the name of the compiler used to c
ompile your kernel, and restart installation. Abort now? (Answer: No)

If you don't have gcc 4.1, then yes you'll have to install it. But look in the /usr/bin directory and see if it's already there. If it is, then you can just delete the symbolic link from gcc -> 4.2 and recreate it so that it points to 4.1.

Ok. I don't have gcc 4.1 installed. I downloaded it but how can I install in an easy way. I have some documentation but is too much to read. Can you write some lines for terminal ?

Hello,

Properly installing GCC is very difficult, more over it could break some parts of your system. So my advice is to install the driver through your package manager (for debian it's synaptic I think)... Go to the ubuntu documentation website (ubuntu is based on debian, so they are very similar), you'll find plenty of topics for ATI driver installation.

A good rule when you use linux is to install "manually" something only when you can't do it by your packages manager.

The package doesn't have a kernel interface for gcc 4.2. So i think I must install gcc 4.1. There are some topics about the same video card driver, but I can't understand them.

To install gcc-4.1 simply do aptitude install gcc-4.1. Then you need to go to the /usr/bin directory, cd /usr/bin. From there type ls -l|grep gcc. You should have a symbolic link from gcc -> gcc-4.2 right now. What you want to do is remove the link, rm gcc. Then recreate it with ln -s /usr/bin/gcc-4.1 /usr/bin/gcc. After that, anytime something wants to use gcc, it will use gcc-4.1 instead.

Maybe, after having installing gcc-4.1, just changing the line "CC=gcc" with "CC=gcc-4.1" is better.

Thank you pljvaldez.

Now I have the symbolic link to gcc 4.1.

But still I can't install the driver.

What do I have to do next ? I must recompile somehow the driver ?

You need to install the linux-headers package for your kernel. What is the output of uname -r and apt-cache search linux-headers?

For uname -r the output is:
"2.6.22-3-686"

For "apt-cache search linux-headers" the output is:

As for the CC version error, normally I would just run command: export CC=gcc-4.1 before running the NVIDIA installer (with headers installed of course).
But some smarty pants here at LQ said I was loco and told me to ignore the error and avoid aborting, just continue with building the module. That works also.
