独服的 CPU 闲着也是闲着，小挖怡情，大挖伤身。本文主要基于 NiceHash Miner 可用的挖矿程序，在 Linux 下编译 CPU 可用的版本

Equihash miner for NiceHash

项目源码在这里，这个 miner 的编译稍稍有些麻烦，很多依赖需要自己安装。由于是纯 CPU 挖矿，尽管页面上提到了 CUDA Kit，但是我们并不需要安装这个。

需要的依赖有这些，Boost 1.62+ 和 CMake 3.5+，但是实际操作中，由于 CMake 和 Boost 库存在版本兼容性问题（Boost 1.63 / CMake 3.7+; Boost 1.64 / CMake 3.8+; Boost 1.65 & 1.65.1 / CMake 3.9.3+），因此不能采用简单的 apt 方式安装，而需要自己下载。

Boost 我选择了 1.65.1，具体安装看这里，具体命令如下：

wget https://dl.bintray.com/boostorg/release/1.65.1/source/boost_1_65_1.tar.bz2
tar --bzip2 -xf /path/to/boost_1_65_1.tar.bz2
cd path/to/boost_1_65_1
./bootstrap.sh
./b2 install

然后安装 CMake 3.9.3+，这里我一开始就被坑了，如果不选择合适的 CMake 版本，则编译时无法找到 Boost 库。

wget https://cmake.org/files/v3.9/cmake-3.9.6-Linux-x86_64.sh
chmod +x /path/to/cmake-3.9.6-Linux-x86_64.sh
sudo /path/to/cmake-3.9.6-Linux-x86_64.sh #Set your own install path during the process
sudo ln -s /path/to/cmake-3.9.6-Linux-x86_64/bin/* /usr/local/bin

然后运行

接下来按照 GitHub 页面操作

1. git clone https://github.com/nicehash/nheqminer.git
   git clone https://github.com/nicehash/nheqminer.git
2. 修改根目录下的 CMakeList.txt，修改这样一行：
   option(USE_CUDA_DJEZO "USE CUDA_DJEZO" ON)
   option(USE_CUDA_DJEZO "USE CUDA_DJEZO" ON) 后面的 ON 为 OFF，这是因为我们要纯 CPU 挖矿，不编译 CUDA 版本。
3. cd nheqminer/cpu_xenoncat/asm_linux/
   cd nheqminer/cpu_xenoncat/asm_linux/
4. chmod +x fasm
   chmod +x fasm
5. sh assemble.sh
   sh assemble.sh
6. cd ../../../
   cd ../../../
7. mkdir build && cd build
   mkdir build && cd build
8. cmake ../nheqminer
   cmake ../nheqminer
9. make -j $(nproc)
   make -j $(nproc)

接下来在 build 目录下就会看到编译好的 nheqminer 程序，使用
