首先解压arm-linux-gcc到制定文件夹

[arm@acer ~]$ sudo tar xvf arm-linux-gcc-3.4.5-glibc-2.3.6.tar.bz2 -C /opt/tool/

配置环境变量：[arm@acer ~]$ sudo vi /etc/profile

添加:PATH=/opt/tool/gcc-3.4.5-glibc-2.3.6/bin:$PATH

export PATH

保存退出。

执行[arm@acer ~]$ sudo source /etc/profile

查看 是否成功：[arm@acer ~]$ arm-linux-gcc

arm-linux-gcc arm-linux-gcc-3.4.5 arm-linux-gccbug

[arm@acer ~]$ arm-linux-gcc -v
