操作步骤：
软件环境： windows10 WSL ubuntu 18.94
1. 搭建交叉编译环境
```sh
cd ~/
# 权限
chmod 777 arm-linux-gcc-4.4.3.tar.gz

# 解压交叉编译工具
tar xzf arm-linux-gcc-4.4.3.tar.gz

#拷贝工具到指定路径
sudo cp ~/opt/ / -rf  

# 添加环境变量
echo "export PATH=\$PATH:/opt/FriendlyARM/toolschain/4.4.3/bin" >> ~/.zshrc
source ~/.zshrc


# 检查arm-linux-gcc -v 版本号
arm-linux-gcc -v
/opt/FriendlyARM/toolschain/4.4.3/bin/arm-linux-gcc: 15: exec: /opt/FriendlyARM/toolschain/4.4.3/bin/.arm-none-linux-gnueabi-gcc: Exec format error      

# 解决方法：
# 工具是32位的，系统是64位的，需要安装32位的库
sudo apt install lib32ncurses5 lib32z1

# 报错：

The following packages have unmet dependencies:
 lib32ncurses5 : Depends: lib32tinfo5 (= 6.0+20160213-1ubuntu1) but it is not going to be installed
                 Depends: libc6-i386 (>= 2.4) but it is not going to be installed
 lib32z1 : Depends: libc6-i386 (>= 2.4) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

# 覆盖安装，参考 https://blog.csdn.net/duanlove/article/details/54666441
sudo apt-get install lib32tinfo5=6.0+20160213-1ubuntu1
sudo apt-get install libc6-i386= 2.4
sudo apt-get install libc6-i386=2.16


$ sudo apt list | grep libc6-i386
WARNING: apt does not have a stable CLI interface. Use with caution in scripts.
libc6-i386/xenial-security,xenial-updates 2.23-0ubuntu11.3 amd64

# 版本对不上，换源，参考 https://blog.csdn.net/qq_35451572/article/details/79516563
# 理论上，替换阿里云服务器上的source.list也是可以的




# 安装32位相关工具
sudo apt install lib32ncurses5 lib32z1

# 编译的时候出错：
/opt/FriendlyARM/toolschain/4.4.3/libexec/gcc/arm-none-linux-gnueabi/4.4.3/cc1: error while loading shared libraries: libstdc++.so.6: cannot open shared object file: No such file or directory

# 安装
sudo apt-get install lib32stdc++6

# 安装成功

# **貌似WSL不支持arm-linux-gcc......**
