Geant4 on Ubuntu 22.04 build instructions for the discerning radiation transport modeller.
The reference instructions for Geant4 can be found here. On Ubuntu 22.04, I found the following packages are required for the build options used below:
xlibmesa-glu-dev libglew-dev libx11-dev libxmu-dev qtbase5-dev
Your millage may vary. To build, first, make a directory called geant4 somewhere sensible, and move into it.
mkdir geant4 cd geant4
Next, clone the ROOT git repository using:
git clone https://github.com/Geant4/geant4.git geant4-git
Now, inside the genat4-git directory, checkout a particular version:
git checkout v11.0.3
And then make build and install directories:
mkdir geant4-v11.0.3-build mkdir genat4-v11.0.3-install
And then build…
cd geant4-v11.0.3-build cmake -DCMAKE_INSTALL_PREFIX=../geant4-v11.0.3-install -DGEANT4_INSTALL_DATA=ON -DGEANT4_USE_X11_OPENGL=ON -DGEANT4_USE_QT=ON ../geant4-git make -j 4 make install
Next add the following to the .bashrc file:
source /path/to/geant4/geant4-v11.0.3-install/bin/geant4.sh
Did I magically have some prerequisites installed? Probably! Does this post merit the sad face at the top? Probably not! I will endeavour to update as required.
