Ubuntu 18.04 将gcc版本降级为5.5版本
Remark: Polynomial algebra 程序由于版本问题只能在gcc 5.0 版本运行, 而ubuntu更新会将gcc 更新到7.0版本,出现冲突(报错:如下)
collect2: error: ld returned 1 exit status
Makefile:34: recipe for target ‘LEORHEKF.exe’ failed
make: *** [LEORHEKF.exe] Error 1
解决方法:
将gcc版本从7.3降级为5.5版本
方法如下:
首先查看自己的gcc版本,Ubuntu18.04上默认的是7.3版本
>>gcc –version
结果为:
gcc (Ubuntu 7.3.0-27ubuntu1~18.04) 7.3.0

降级方法
1. 下载gcc/g++ 5
sudo apt-get install -y gcc-5
sudo apt-get install -y g++-5
2. 链接gcc/g++实现降级
cd /usr/bin
sudo rm gcc
sudo ln -s gcc-5 gcc
sudo rm g++
sudo ln -s g++-5 g++
确认版本降级成功
再次查看gcc版本,可以看到已经降级.
>>gcc –version
gcc (Ubuntu 5.5.0-12ubuntu1) 5.5.0 20171010
