How to compile xmr-stak (2.10) under CentOS 7 for CPU mining cryptocurrencies in September 2019

A time to refresh our old article on how to compile xmr-stak for CPU mining with the new version and this time a new GNU GCC version (version 8.3, the last article we used 7.x – How to compile xmr-stak (2.4.5) under CentOS 7 for CPU mining cryptocurrencies). Always use the latest available GNU GCC packages because the latest version of GNU GCC could add some optimizations to the binary compiled code and you may have a CPU miner with better performance!
Thanks to xmr-stak we can have one application capable of mining many different cryptocurrencies based on different algorithms. XMR-STAK is GPU and CPU miner and here we present only the CPU ability under CentOS 7 using our AMD Threadripper 1950X.
The software in this article:

  • CentOS 7 – CentOS Linux release 7.6.1810 (Core)
  • GNU GCC – gcc version 8.3.1 20190311 (Red Hat 8.3.1-3) (GCC)
  • XMR-STAK – 2.10.7

As said many times working with crypto-currency it is mandatory to do the things yourself – do not trust any binary made by someone on the Internet. It is easy to build your miner yourself with the code from the official repository!

So here are the steps to build the XMR-STAK for CPU mining:

STEP 1) Update your system and install the following dependencies

Always start with update command and then install the dependencies in order first install all the new repositories and then the dependency binaries.

sudo yum update -y
sudo yum install -y centos-release-scl epel-release
sudo yum install -y cmake3 devtoolset-8-gcc* hwloc-devel libmicrohttpd-devel openssl openssl-devel make git screen wget

We are going to use GNU GCC 8 to build the XMR-STAK. More on the subject of how to install GNU GCC 8 and what is “devtoolset” here – How to install GNU GCC 8 on CentOS 7.

How to install GNU GCC 8 on CentOS 7

It has been long after releasing the GNU GCC 8.x, but at last, there is a trusted repository, which has offered us packages for GNU GCC 8.x, which won’t break your system! Many of us prefer CentOS 7 because it offers free enterprise-class operating system and as mentioned in our article before – How to install new gcc and development tools under CentOS 7 there are a couple of approved external repositories for CentOS, which you can trust https://wiki.centos.org/AdditionalResources/Repositories. In one of them Software Collection – https://www.softwarecollections.org/en/scls/ several months ago the GNU GCC 8.x packages were added!
At present, the GNU GCC version is gcc (GCC) 8.3.1 20190311 (Red Hat 8.3.1-3).
Here are the steps how you can install GNU GCC 8 and how you can use it:

STEP 1) Update your system and install the repository in your system

The commands:

yum update -y
yum -y install centos-release-scl
