进入容器后输入
arm-linux-gcc -v
如果找不到命令。先输入
source /etc/profile
再次输入 版本查看
arm-linux-gcc -v

这就是交叉编译器的创建过程
请自行百度 arm-linux-gcc 的使用,来进一步学习如何编译
如果你不关心容器的构建过程,下边的都不用看了。

上传压缩包到 /home目录
解压
cd /home
tar -zxvf arm-linux-gcc-4.4.3-20100728.tar.gz
cp -r /home/opt/FriendlyARM/toolschain/4.4.3 /usr/local/arm
配置环境变量
vi /etc/profile
末尾添加
export PATH=$PATH:/usr/local/arm/bin
source /etc/profile
使用
arm-linux-gcc -v

我们在/home 下新建简单代码文件
#include"stdio.h"
int main(){
printf("hello arm\n");
}
先编译生成 x86 的执行问文件
gcc helloArm.c -o hellox86
执行查看效果
./hellox86
hello arm
arm-linux-gcc helloArm.c -o helloarm
报错 找不到 libstdc++.so.6
yum whatprovides libstdc++.so.6
libstdc++-4.8.5-39.el7.i686 : GNU Standard C++ Library
安装依赖
yum install libstdc++-4.8.5-39.el7.i686
arm-linux-gcc helloArm.c -o helloarm
执行
./helloarm
-bash: ./helloarm: cannot execute binary file

下载上传
https://github.com/multiarch/qemu-user-static/releases
/usr/bin/qemu-aarch64-static
/usr/bin/qemu-arm-static
到宿主机的/usr/bin 目录下
chmod 777 /usr/bin/qemu-aarch64-static
chmod 777 /usr/bin/qemu-arm-static
指定 docker 参数
docker run --rm --privileged multiarch/qemu-user-static:register
docker run -it -v /usr/bin/qemu-aarch64-static:/usr/bin/qemu-aarch64-static -p 51000:22 --name arm64 arm64v8/ubuntu
docker run -it -v /usr/bin/qemu-arm-static:/usr/bin/qemu-arm-static -p 51000:22 --name arm32 arm32v7/ubuntu
把我们之前的编译的文件放到这里 /home
直接运行
/home/helloarm
./helloarm: No such file or directory
这里并不是说找不到可执行文件,而是找不到
执行文件中的依赖
回到宿主机
宿主机执行 readelf -a helloarm
[Requesting program interpreter: /lib/ld-linux.so.3]
把目标机缺少的 /lib 安装一下就好了
把宿主机 /usr/local/arm/arm-none-linux-gnueabi/lib
内容拷贝到 目标机 /lib
宿主机
cd /usr/local/arm/arm-none-linux-gnueabi/lib
