error: #error -- unsupported GNU version! gcc versions later than 6 are not supported!

当我在运行make.sh脚本的时候，出现以下错误：

 error: #error -- unsupported GNU version! gcc versions later than 6 are not supported!

经过一番谷歌，尝试到可用的解决办法是：
修改gcc的版本，具体操作如下：

sudo rm /usr/local/cuda/bin/gcc
sudo rm /usr/local/cuda/bin/g++
sudo apt install gcc-5 g++-5
sudo ln -s /usr/bin/gcc-5 /usr/local/cuda/bin/gcc
sudo ln -s /usr/bin/g++-5 /usr/local/cuda/bin/g++
