因为当前gcc版本是9.x, 找不到 compiler-gcc9.h, 复制compiler-gcc5.h成compiler-gcc9.h

Kernel doesn't support PIC mode for compiling?

CLion头文件报错

标红，不能跳转

sudo cp -r ./include/linux/ /usr/local/include/

不要copy到/usr/include, 否则当前运行的操作系统坏了。

mzh@DESKTOP-GITL67P:/mnt/e/CLionProjects/linux-3.10.99/linux-3.10.99$ sudo rsync -avz ./include/ /usr/local/include/

对于报错Time skewed

sudo ntpdate -uv time.windows.com
