How To Install HepMC3 on CentOS 8

HepMC3 is C++ Event Record for Monte Carlo Generators

Introduction

In this tutorial we learn how to install HepMC3 on CentOS 8.

What is HepMC3

The HepMC3 package is an object oriented, C++ event record for High Energy Physics Monte Carlo generators and simulation, described in A. Buckley et al., “The HepMC3 Event Record Library for Monte Carlo Event Generators” Comput.Phys.Commun. 260 (2021) 107310, arxiv It is a continuation of the HepMC2 by M. Dobbs and J.B. Hansen described in “The HepMC C++ Monte Carlo event record for High Energy Physics” (Comput. Phys. Commun. 134 (2001) 41). In the version 3 the package has undergone several modifications and in particular, the latest HepMC3 series is a completely new re-write using currently available C++11 techniques, and have out-of-the-box interfaces for the widely used in HEP community ROOT and Python.

We can use yum or dnf to install HepMC3 on CentOS 8. In this tutorial we discuss both methods but you only need to choose one of method to install HepMC3.
