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/
但是这样会重复定义，所以还是用vim算了。
mzh@DESKTOP-GITL67P:/usr/local/include$ rm -rf acpi/ asm-generic/ clocksource/ config/ crypto/ drm/ dt-bindings/ generated/ keys/ linux3x/ math-emu/ media/ memory/ misc/ net/ pcmcia/ ras/ rdma/ rxrpc/ scsi/ sound/ target/ trace/ uapi/ video/ xen/
sudo apt-get install ctags

WORKDIR="/mnt/e/CLionProjects/linux-3.10.99/linux-3.10.99"
find "${WORKDIR}" -name "*.[c|h]" | xargs ctags -f "${WORKDIR}/tags"
find /usr/include -name "*.h" | xargs ctags -a "${WORKDIR}/tags"ctags -a 表示追加索引内容到tags文件。Linux不依赖libc.so，所以不需要添加/usr/include。
./tags.sh
在~/.vimrc中添加
set tags="/mnt/e/CLionProjects/linux-3.10.99/linux-3.10.99/tags"
对于报错Time skewed
