sudo apt-get install gcc-5=5.4.0-6ubuntu1~16.04.12

查看安装有的gcc版本

ls /usr/bin/gcc*

如有多个gcc版本，则使用以下命令进行版本管理

sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-5 40 sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-9 50 sudo update-alternatives --config gcc

g++安装： 与gcc同理
