前回の CUDA インストールに続き nheqminer のインストールして zcash を掘ります。
基本的に公式ドキュメントの手順でうまく行きますが細かいところがコピペでは完結しなかった気がします。

$ git clone https://github.com/nicehash/nheqminer.git

$ export CUDA_CUDART_LIBRARY="/usr/local/cuda/lib64/libcudart.so"

$ cd nheqminer/cpu_xenoncat/asm_linux 

$ chmod 774 ./fasm

$ sh assemble.sh

$ cd ../../../

$ mkdir build && cd build

$ cmake -DCUDA_CUDART_LIBRARY=CUDA_CUDART_LIBRARY ../nheqminer/

$ make -j $(nproc)

ここまでエラー無く完走すればビルドは完了。
後は自分の環境にあわせてオプションを与えて実行してあげればよい。

$ ./nheqminer -h

Parameters: 
        -h              Print this help and quit
        -l [location]   Stratum server:port
        -u [username]   Username (bitcoinaddress)
        -a [port]       Local API port (default: 0 = do not bind)
        -d [level]      Debug print level (0 = print all, 5 = fatal only, default: 2)
        -b [hashes]     Run in benchmark mode (default: 200 iterations)

CPU settings
        -t [num_thrds]  Number of CPU threads

自分の場合は bitcoin でも有名な slushpool でプールマイニングをしているので

-l でプールを指定
-u でプールの ID と worker 名
-t で CPU のスレッド数
-cd でビデオカード(NVIDIA)の 0 番 ※ -od

を指定して実行した。

$ ./nheqminer -l zec.slushpool.com:4444 -u [USERID].worker1 -t 4 -cd 0
