Hi, I will greatly appreciate help on the following "Fatal error":

maluba@maluba-Satellite-C850-F32Z:~$ cd Geant4.10/B1-build/ maluba@maluba-Satellite-C850-F32Z:~/Geant4.10/B1-build$ ls CMakeCache.txt exampleB1 init.mac run1.mac CMakeFiles exampleB1.in init_vis.mac run2.mac cmake_install.cmake exampleB1.out Makefile vis.mac maluba@maluba-Satellite-C850-F32Z:~/Geant4.10/B1-build$ ./exampleB1

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.

I have successfully installed and reinstalled Geant4.9 (also Geant4.10 now) several times, but this problem have not gone away. The only time I have successfully run an example (B1 to be specific) is after reinstalling Ubuntu on my laptop (which I have done thrice in a period of 6months).

It's complaining about data files, which I have ensured are present in maluba@maluba-Satellite-C850-F32Z:~/Geant4.10/geant4.10.00-install/share/Geant4-10.0.0/data$.

I am a newbie with Geant4, and have seen (have even posted on this forum before) a lot of people complaining about problem similar to this one on the forums, but solutions seems to be computer/OS/and Installation specific.

Your help will be much appreciated. If it's necessary, I am running Geant4 in Ubuntu 12.04.3, and also use the cmake-curseses-gui (ccmake).

Thank you.
