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?

bash 复制代码

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

$ cat tags.sh

bash 复制代码

#/bin/bash

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

sudo ntpdate -uv time.windows.com
