Using the GSI installation of Geant4

There are different versions of Geant4 installed at GSI. An installation of geant4.9.5 can be found at

/usr/local/pub/debian5.0/x86_64/gcc432-11/sim/geant4.9.5-build

You can use this installation by loading the script

source /usr/local/pub/debian5.0/x86_64/gcc432-11/sim/geant4.9.5-build/geant4make.sh

This gives you a working environment that uses the "old" build system with GNUmakefiles instead of cmake. Note that this is a 64-bit installation. That means you should go to a 64-bit system to use it. For example

ssh squeezelust64

The data sets are in the folder

/usr/local/pub/debian5.0/x86_64/gcc432-11/sim/geant4.9.5/data

and the paths are not automatically set. That means you have to set the corresponding environment vairbles manually. It is a good idea to put the following lines into a file called geant4login , and put it e.g. to your local /bin folder.

source /usr/local/pub/debian5.0/x86_64/gcc432-11/sim/geant4.9.5-build/geant4make.sh

export G4LEDATA=/usr/local/pub/debian5.0/x86_64/gcc432-11/sim/geant4.9.5/data/G4EMLOW6.23

export G4LEVELGAMMADATA=/usr/local/pub/debian5.0/x86_64/gcc432-11/sim/geant4.9.5/data/PhotonEvaporation2.2

export G4NEUTRONHPDATA=/usr/local/pub/debian5.0/x86_64/gcc432-11/sim/geant4.9.5/data/G4NDL4.0

export G4NEUTRONXSDATA=/usr/local/pub/debian5.0/x86_64/gcc432-11/sim/geant4.9.5/data/G4NEUTRONXS1.1

export G4PIIDATA=/usr/local/pub/debian5.0/x86_64/gcc432-11/sim/geant4.9.5/data/G4PII1.3

export G4RADIOACTIVEDATA=/usr/local/pub/debian5.0/x86_64/gcc432-11/sim/geant4.9.5/data/RadioactiveDecay3.4

export G4REALSURFACEDATA=/usr/local/pub/debian5.0/x86_64/gcc432-11/sim/geant4.9.5/data/RealSurface1.0

Then, all you have to do is call

. geant4login

and your can use GSI Geant4.
