ubuntu 22.04 安装驱动可能遇到的坑

第一个坑【gcc版本不匹配】

请确认你的gcc版本是不是12的，11是编译不通过的。

一般在最后编译时报错，在/var/log/nvidia-installer.log日志中可以看到以下字样

bash 复制代码

Warning: Compiler version check failed:

The major and minor number of the compiler used to
compile the kernel:

x86_64-linux-gnu-gcc-12 (Ubuntu 12.3.0-1ubuntu1~22.04) 12.3.0, GNU ld (GNU Binutils for Ubuntu) 2.38

does not match the compiler used here:

cc (Ubuntu 11.4.0-1ubuntu1~22.04) 11.4.0

It is recommended to set the CC environment variable
to the compiler that was used to compile the kernel.

To skip the test and silence this warning message, set
the IGNORE_CC_MISMATCH environment variable to "1".
However, mixing compiler versions between the kernel
and kernel modules can result in subtle bugs that are
difficult to diagnose.

*** Failed CC version check. ***

没有找不到 gcc 或者cc

bash 复制代码

cd /usr/bin/
ls -al | grep gcc

去到/usr/bin目录下查看是否有gcc文件，如果只有gcc-12，需要创建软链接。

bash 复制代码

sudo ln -s /usr/bin/gcc-12 /usr/bin/gcc
sudo ln -s /usr/bin/gcc /usr/bin/cc

3.没有cc文件，报错如下

bash 复制代码

 ERROR: The CC sanity check failed:

         The C compiler '/usr/bin/cc' does not appear to be able to
         create object files.  Please make sure you have
         your Linux distribution's libc development package
         installed and that '/usr/bin/cc' is a valid C compiler
         name.

先检查cc软链接是否存在，可以参考坑2。

再去看看/usr/lib/gcc/x86_64-linux-gnu/12/目录下是否有cc1文件.
