unsupported GNU version! gcc versions later than 7 are not supported


换了新的ubuntu系统：20.04后  gcc g++版本都很高了

看下面的：
jingyun@jingyun-Ubuntu:~$ gcc --version
gcc (Ubuntu 9.3.0-10ubuntu2) 9.3.0

解决cuda10.0 gcc versions later than 7 are not supported的方法
解决cuda10.0 gcc和g++版本过高的问题gcc versions later than 7 are not supported


操作方法：

sudo apt-get install gcc-7 g++-7
sudo mkdir /usr/local/gcc7
cd /usr/local/gcc7
sudo ln -sf /usr/bin/gcc-7 cc
sudo ln -sf /usr/bin/gcc-7 gcc
sudo ln -sf /usr/bin/g++-7 g++
sudo ln -sf /usr/bin/cpp-7 cpp
sudo ln -sf /usr/lib/gcc/x86_64-linux-gnu/7/cc1 .
sudo ln -sf /usr/lib/gcc/x86_64-linux-gnu/7/cc1plus .


如果临时修改终端的环境变量：

1. export PATH=/usr/local/gcc7:$PATH

复制代码

也可以sudo vim .bashrc   放最后面 永久修改！

这样nvcc，查找gcc时就会先找gcc7，问题就解决了。
