编译 ethminer 时不支持 5 以上的 gcc 版本

重要事项：

大家好，Ubuntu 用户。最近我决定进入以太坊挖矿世界并ethminer自行编译。cuda然而，安装后，我遇到了一个小问题。在执行sudo cmake --build .后cmake .. -DETHASHCUDA=ON -DETHASHCL=OFF，控制台输出以下内容：

[  0%] Built target BuildInfo.h
[ 29%] Built target devcore
[ 41%] Built target ethash

附加信息：

我使用 安装了 CUDA sudo apt install cuda。它安装了nvidia-275它cuda本身（以及许多其他东西）

这解决了我的问题：

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++
