Hi, I created some experimental binary packages of Geant4 11.0.1 for CentOS Stream 8 and would like to get feedback from the community ahead of next release, so that we can maybe offer binary releases like this officially in the future for the most common platforms. In order to install the experimental Geant4 binary packages, please follow the instructions below:
- Create a repository configuration for Geant4:
Create a file named /etc/yum.repos.d/geant4.repo with the following contents:
[geant4]
name=Geant4 Collaboration
baseurl=http://lcgpackages.web.cern.ch/lcgpackages/test/geant4
enabled=1
gpgcheck=0
priority=10
- Install
epel-releasewithdnf install -y epel-release
Geant4 must depend on epel-release because xerces-c is only available there and is needed for GDML support in Geant4.
- Install Geant4 with
dnf install -y geant4-devel
Note that the main package provides only the libraries without headers. Installing geant4-examples or geant4-devel will pull all dependencies needed to build your own projects against Geant4. If you create your own binary and distribute it pre-compiled, then only the geant4 package will be required to run it.
- Try to build your package using Geant4
For example, below I show how to build TestEm3 using the geant4-examples package:
$ sudo dnf install geant4-examples
...
$ cmake -S /usr/share/geant4/examples/extended/electromagnetic/TestEm3 -B TestEm3-build

Notes:
I’ve tried to create as complete a package as possible, however, I had to keep HDF5 support disabled because the binary package that comes with the distribution is not compatible with compiling Geant4 with multi-threading support. Open Inventor packages (SoXt and/or SoQt) are also not available. Python support also needs a small patch to work, so I left it out for this experimental package. The output of geant4-config --help is as follows:
$ geant4-config --help | sed -ne '/Known Features/,/^$/{ p }'
