This repository provides binaries of Geant4 for use in GitHub actions, on ubuntu-latest. To see the list of available versions, please consult the releases.

Using the binaries in your workflow

Each release is named after the version of Geant4, for example geant4.10.07.p03. The binaries are made available as an asset with the name suffixed by -binaries.tar.gz. They are built with GEANT4_USE_GDML=ON, so you need to install libxerces-c-dev. To use the installation in a workflow, download and extract the archive to $HOME and source geant4.sh:

- name: Install dependencies
  run: sudo apt-get install libxerces-c-dev
- name: Install Geant4
  run: |
    wget https://github.com/hahnjo/geant4-actions-binaries/releases/download/$GEANT4_VERSION/$GEANT4_VERSION-binaries.tar.gz
    tar xf $GEANT4_VERSION-binaries.tar.gz -C $HOME
  env:
    GEANT4_VERSION: "geant4.10.07.p03"
- name: Build application
  run: |
    source ~/Geant4/bin/geant4.sh

Alternatively, you can use a build matrix to test against multiple versions of Geant4:

strategy:
  matrix:
    version: [
      geant4.10.07.p03,
      geant4.10.06.p03,
    ]

and then install with:

- name: Install Geant4
  run: |
    wget https://github.com/hahnjo/geant4-actions-binaries/releases/download/${{ matrix.version }}/${{ matrix.version }}-binaries.tar.gz
    tar xf ${{ matrix.version }}-binaries.tar.gz -C $HOME
