The newest version of EXOSoftware uses Geant4.3.9.p01. This Geant4 version has been installed on lheppc83 and tested with the EXOAnalysis module. The following steps has been performed:

  • Install CLHEP version 2.0.4.5
  • Download the source files from http://geant4.cern.ch/
  • Unpack the package in /opt/geant4
  • Download the following data files
G4ABLA.3.0.tar.gz
G4EMLOW.6.9.tar.gz
G4NDL.3.13.tar.gz
G4RadioactiveDecay.3.2.tar.gz
PhotonEvaporation.2.0.tar.gz
RealSurface.1.0.tar.gz

and unpack them in /opt/geant4/v4.9.3.p01/data

  • Make sure all G4 environment variables are unset
  • In the install directory, do the initial build using the configure script
./Configure -build

The script will lead you through the installation process. During this process, make sure you select this non-default option 

Do you want to copy all Geant4 headers in one directory? [y]

This will copy all header files in /opt/geant4/v4.9.3.p01/include

  • Run the configure script without any option
./Configure

This will generate the environment setup script env.sh which you can source (e.g. in .bashrc) to set up environment variables.

  • Install Geant4 by typing
./Configure -install

This will install libraries and necessary source code in lib/geant4, include/geant4
