I have installed the Geant4.10 on Ubuntu 12.04 .I followed all the instructions but still, I am getting the following error while running a given example. "Low energy electromagnetic data are needed. This is a NEW requirement for standard EM physics since geant4 9.5. Please set the environmental variable G4LEDATA to point to your G4EMLOW directory. Note: EMLOW6.23 or above is needed for Bremsstrahlung data. Data are available from the Geant4 download page. Photon-evaporation data are needed. Please set the environmental variable G4LEVELGAMMADATA to point to your PhotonEvaporation directory. Data are available from the Geant4 download page. G4NEUTRONXS are needed. Please set the environmental variable G4NEUTRONXSDATA to point to your G4NEUTRONXS directory. Data are available from the Geant4 download page. *** Fatal error: Missing mandatory data for this simulation engine *** *** Fatal Exception *** core dump *** -------- EEEE -------- G4Exception-END --------- EEEE ------- *** G4Exception: Aborting execution *** Aborted (core dumped) "
Are the listed variables (G4LEDATA, G4LEVELGAMMADATA and G4NEUTRONXSDATA) set in the environment? If not, then the relevant shell script (geant4.sh for general running, geant4make.sh if you are building applications using Geant4's GNUmake system) needs to be sourced. I think the errors indicate that the variables are not set, but it's worth double checking.
