Event Record for Monte Carlo Generators
The HepMC package is an object oriented event record written in C++ for High Energy Physics Monte Carlo Generators. Many extensions from HEPEVT, the Fortran HEP standard, are supported: the number of entries is unlimited, spin density matrices can be stored with each vertex, flow patterns (such as color) can be stored and traced, integers representing random number generator states can be stored, and an arbitrary number of event weights can be included. Particles and vertices are kept separate in a graph structure, physically similar to a physics event. The added information supports the modularisation of event generators. The package has been kept as simple as possible with minimal internal/external dependencies. Event information is accessed by means of iterators supplied with the package. Reference: M. Dobbs and J.B. Hansen, Comput. Phys. Commun. 134 (2001)41.

Use flags of 3.3.1
- doc Add extra documentation (API, Javadoc, etc). It is recommended to enable per package instead of globally
- test Enable dependencies and/or preparations necessary to run tests (usually controlled by FEATURES=test but can be toggled independently)
- examples Install examples, usually source code
- python Add optional support/bindings for the Python language
- root Build with ROOTIO enabled
- static-libs Build static versions of dynamic libraries as well
3 expansion flags (python targets, ABIs, cpu flags…)
- python_single_target_python3_12
- python_single_target_python3_13
- python_single_target_python3_14
