Has anyone had any luck using geant4 with the current fairbase (10/10/12)?? If so, can you please reply. I am unable to run fairroot with geant4 and I need to know if the problem is because of a bug or because of my personal error.
I tried running the rutherford example,
cd fairbase/examples/rutherford/macros
root run_rutherford.C
And it seemed to run without a hitch.
However, run_rutherford as it is in the repository uses Geant3. I want to use Geant4, so I replace run->SetName("TGeant3"); with run->SetName("TGeant4");
After I try to run_rutherford.C again, I get a segmentation fault. The error is described in geant4SeFault.txt.
I naively copied g4libs.C from sep12/transport/geant4_vmc into my sep12-build/share/root/macros and into my gconfig folder in my fairbase. Note: the g4libs.C was not found at all in my sep12 build folder, which might suggest that sep12 is faulty in this aspect. After copying g4libs.C into said folders, I ran rutherford again and obtained the error described in geant4now.txt. I don't know what else to try, so any help is greatly appreciated.
Thank you in advance

Hi Florian,
I tried to updated my local copy
svn update
cd build
cmake ..
make
I then went to my rutherford directory and tried to run the rutherford example.
root run_rutherford.C
but I get the same segmentation fault. I pretty much get all the same errors outlined in my original post whether or not I copy g4libs.C into the directories fairroot thinks I should have them in.
I also tried changing the parameters of FairIonGenerator to be Z,A,Q = 3,6,3 and it still gave me the same segmentation fault. I even commented out both FairBoxGenerator and FairIonGenerator.
The macro works just fine with TGeant3.
Based on what I just told you, I am very convinced that fairroot doesn't know what Geant4 is. Did it work with your fairroot? If it worked on your fairroot and not mine, maybe it suggests that my fairroot is a little broken.
I'm going to try a couple more things out later today, but it looks like geant4 is, as of now, not working at all with fairroot, or at least mine.
Thank you for your help and reply. I really appreciate it.
-Raphael

Hi Raphael,
now I see that you have a different error then I had. Could you please send me the output produced when running the run_rutherford.C macro.
Also please send me the file config.sh from your build directory.
For me it looks like some of the environment variables are not set properly.
After my changes the run_rutherford.C macro works as expected using only FairRoot.
Ciao
Florian

Hi Raphael,
please do the following steps to reinstall only the geant4vmc package.
1. Delete libgeant4vmc.so in the lib subdir of your installation directory. In your case the file is probably in /home/raphael/Documents/sep12-build/
2. Delete the following directory in the main source directory of the external packages: "transport/geant4_vmc"
3. Do a "svn update" in the main source directory of the external packages.
4. Rerun the configure.sh script. This should reinstall geant4_vmc
5. Remove the build directory of your FairRoot installation.
6. Rebuild FairRoot
After this I hope you will have a correct config.sh script and a running version of FairRoot.
Ciao
Florian
