xmr-stak-cpu 在Centos 7挖矿

安装编译

yum -y install epel-release
yum -y install centos-release-scl cmake3 hwloc-devel libmicrohttpd-devel openssl-devel git screen nano
yum -y install devtoolset-4-gcc*
scl enable devtoolset-4 bash
git clone https://github.com/fireice-uk/xmr-stak-cpu.git
cd xmr-stak-cpu
cmake3 .
make install

如果出现一下情况,需要升级gcc

升级GCC

wget http://ftp.gnu.org/gnu/gcc/gcc-6.1.0/gcc-6.1.0.tar.bz2 
tar -jxvf gcc-6.1.0.tar.bz2  
cd gcc-6.1.0  
./contrib/download_prerequisites
mkdir build  
cd build
../configure -enable-checking=release -enable-languages=c,c++ -disable-multilib
