Gentoo Linux下安装NVIDIA显卡驱动（NVIDIA installer can't find kernel source/build files）

Gentoo 11.2默认为3.0.6内核，如果安装官方二进制NVIDIA显卡驱动，提示如下错误

ERROR: If you are using a Linux 2.4 kernel, please make sure   you either have configured kernel sources matching your   kernel or the correct set of kernel headers installed   on your system.   If you are using a Linux 2.6 kernel, please make sure   you have configured kernel sources matching your kernel   installed on your system. If you specified a separate   output directory using either the "KBUILD_OUTPUT" or   the "O" KBUILD parameter, make sure to specify this   directory with the SYSOUT environment variable or with   the equivalent nvidia-installer command line option.   Depending on where and how the kernel sources (or the   kernel headers) were installed, you may need to specify   their location with the SYSSRC environment variable or   the equivalent nvidia-installer command line option.

这是由于显卡驱动不支持3.0内核，可以给显卡驱动打补丁来安装，点击下载补丁文件

然后执行

sh NVIDIA-Linux-x86_64-270.41.19.run -x

将驱动解压至当前目录，然后进入目录打上patch文件

cd NVIDIA-Linux-x86_64-270.41.19/kernel/patch -p0 < kernel-3.066.patch

然后

cd ..nvidia-install --kernel-source-path /usr/src/linux

安装成功OK！
