Thanks, I've only a server with Centos6 atm that I can use and it was a bit tricky to compile cpuminer-opt onto.
For Centos it is:
sudo yum install centos-release-scl epel-release
sudo yum install cmake3 devtoolset-4-gcc* hwloc-devel libmicrohttpd-devel openssl-devel make
scl enable devtoolset-4 bash
git clone https://github.com/fireice-uk/xmr-stak.git
mkdir xmr-stak/build
cd xmr-stak/build
cmake3 ..
make install
