1. gcc

CentOS
之前的安装要先执行 yum install centos-release-scl，但是这种方法已经不 work 了，新方法如下

yum list | grep gcc-toolset  # 查看可以安装的版本
sudo yum install -y gcc-toolset-9  # 安装gcc v9
source /opt/rh/gcc-toolset-9/enable  # 启用gcc v9

用 gcc -v 就可以查看到当前版本了，可以看到已经更新到了 gcc v9

(python) ➜  2D-Scene git:(master) ✗ gcc -v                             
Using built-in specs.
