还是比较习惯使用Windows，
最近在使用windows sever2019的Ubuntu18.4编译openwrt，
其中lienol大源码编译，基于openwrt19.7的，基本一遍就能成功
但是lean大源码，出错的几率很大，下面记录了遇到的坑

除了要全局留学上网，下载好文件make download -j8 V=s，还有以下的可能会出错

1、要开启文件系统大小写文件名
fsutil.exe file setCaseSensitiveInfo D:\openwrt\ enable

2、Linux系统与Windows文件系统权限管理不一样，WSL安装目录也可能会有影响，
可以使用 LxRunOffline 对 WSL 目录进行转移
mv: cannot move 'bin/aclocal.tmp2' to 'bin/aclocal.tmp': Permission denied
Makefile:51: recipe for target '/mnt/e/Downloads/OpenWrt/lede/build_dir/host/automake-1.15.1/.configured' failed
make[3]: * [/mnt/e/Downloads/OpenWrt/lede/build_dir/host/automake-1.15.1/.configured] Error 1
make[3]: Leaving directory '/mnt/e/Downloads/OpenWrt/lede/tools/automake'

make[2]: * [tools/automake/compile] Error 2

nnyyyynyyyyyyyyyyyyyyyyyyynynnyyynnyy] Error 2

3、D:\WSL\rootfs\etc，wsl.conf文件，定义变量问题
[automount]
options = "metadata,umask=22,fmask=111"

[filesystem]
umask = 022

[interop]
enabled = "false"
appendWindowsPath = "false"

4、居然Windows变量里面的haozip也有影响，要删掉
The relative path 'Files/2345Soft/HaoZip' is included in the PATH

终于，成功了
