1. Load required modules and set environment variables [Step 1-4]

Paste the below lines into your terminal. (Do NOT put these directly in ~/.bashrc.)

module purge
module load CMake/3.26.4
module load expat/2.5.0
module load cpeIntel/23.09

export CC=cc CXX=CC FC=ftn F77=ftn F90=ftn

2. Download Geant4 [Step 5]

mkdir $HOME/Applications
mkdir $HOME/Applications/GEANT4
cd $HOME/Applications/GEANT4
wget https://gitlab.cern.ch/geant4/geant4/-/archive/v11.1.3/geant4-v11.1.3.tar.gz
tar -zxf geant4-v11.1.3.tar.gz

3. Install Geant4 [Step 7]

cd $HOME/Applications/GEANT4/
rm -rf geant4-install geant4-build
mkdir geant4-{build,install}
cd geant4-build
cmake ../geant4-v11.1.3 -DGEANT4_INSTALL_DATA=OFF -DGEANT4_BUILD_MULTITHREADED=ON -DCMAKE_INSTALL_PREFIX=../geant4-install -DGEANT4_USE_QT=OFF -DGEANT4_USE_OPENGL_X11=OFF -DGEANT4_USE_RAYTRACER_X11=OFF
make -j8 install

cd $HOME/Applications/GEANT4/geant4-install
ln -s lib64 lib

-DCMAKE_PREFIX_PATH=/usr/lib/qt5 -DGEANT4_USE_QT=ON is changed to -DGEANT4_USE_QT=OFF.
-DGEANT4_USE_OPENGL_X11=OFF -DGEANT4_USE_RAYTRACER_X11=OFF
/geant4-install/lib is symbolically linked to /geant4-install/lib64.
