module use /scigroup/cvmfs/geant4/modules
module load gemc/5.10Note: the above commands are not needed if load the clas12 module.
We distribute releases of Geant4 on CVMFS for the following platforms:
- Linux: Fedora 36, AlmaLinux 9, Ubuntu24
- MacOS: macOS 14.5 (Sonoma)
If you have access to a CVMFS client and your OS is supported, you can load Geant4 with the following commands:
module use /cvmfs/oasis.opensciencegrid.org/jlab/geant4/modules
module load gemc/5.10Note: the above commands are not needed if load the clas12 module.
module avail gemc: shows available gemc modules
module load geant4/11.2.2: loads standalone geant4 libraries 11.2.2
module switch gemc/dev: switch to gemc (clas12Tags) dev version
module show <module>/<version>: shows what is loaded by a module
To download and compile Geant4 and/or Gemc on your local machine, follow these instructions.
Below we''ll use /opt/software as the installation location, but it can be any directory of your choice.
Make sure you have write permissions on the directory you choose. You can always change permissions like this:
chown -R $USER /opt/software
Do this only once. If you have already cloned the repo, skip this step.
cd /opt/software
git clone https://github.com/jeffersonlab/ceInstall
module use /opt/software/ceInstall/modules
module load gemc/5.10
We suggest to add the commands above to your shell login file to have them available every time you log in.
Make sure the requirements for the libraries / environment installation listed at the bottom of this page are met.
After the steps above: module load sim_system will load the installation scripts location.
install_geant4 11.2.2will install geant4install_gemc 5.10will install gemc. This can be run standalone or after the geant4 installation.
Both installation scripts will check for existing installations and will not overwrite them.
moule avail geant4 or module avail gemc will show the versions available for installation.
The source code of the geant4 examples is in $G4INSTALL/source/examples/.
To compile one of the examples, create a build directory and run cmake using
the syntax below, where $G4INSTALL/source/examples/basic/B3 is selected
as an example, in a machine with 4 cores (-j4)
mkdir build ; cd build
cmake -DGeant4_DIR=$G4INSTALL/lib $G4INSTALL/source/examples/basic/B3
make -j4
Software based on compiled code (C++, fortran, etc) is organized in the SIM_OSRELEASE
directory. SIM_OSRELEASE, set by the modules, is a string is composed by the OS name and the compiler major version.
For example: macosx14-clang15, fedora34-gcc12.
Architecture-independent stuff (python, JAVA, etc) is organized in then noarch directory.

- Qt5Gui
- Qt5Widgets
- Qt5OpenGL
- Qt5PrintSupport

Find below the commands to install these requirements. Please email any corrections to [Maurizio](mailto:[email protected]?subject=CeInstall Requirements Corrections).
brew install gnu-tar wget cmake mysql qt@5 scons freeglut modules sqlite
Note: As of 8/2024: the mysql_native_password authentication plugin has been removed in mysql v9 and CCDB will not work w/o it. So, for now, we need to install mysql v8.4:
brew install [email protected]
export PATH="/opt/homebrew/opt/[email protected]/bin:$PATH"
export DYLD_LIBRARY_PATH="/opt/homebrew/opt/[email protected]/lib:$DYLD_LIBRARY_PATH"
brewDir=$(brew --prefix)
source $brewDir/opt/modules/init/zsh` or `. $brewDir/opt/modules/init/bash
set brewDir=`brew --prefix`
source $brewDir/opt/modules/init/tcsh
In order to avoid re-typing them every time, the lines could be added to the files .tcshrc or .cshrc
in your home directory, so they will be executed every time you open a new terminal.
You can create the file if it does not exist.

- mlibrary 1.7 is associated with geant4 10.6.2 and clhep 2.4.1.3
- mlibrary 1.8 is associated with geant4 10.7.4 and clhep 2.4.4.2
- gemc 5.9 is deprecated because of the above reason (cannot mix different mlibrary and geant4 versions)
