We need to use the G4PhotoNuclearProcess class but I did not found it in the documentaion. When we can expect to get it? Using G4PhotoNuclearCrossSection.cc our Geant4 application crashes (Segmentation fault) as said in problem report #390 but with the additinal lines given there it runs. I'm not sure if this corrections will solve the problem completely. We have compiled the Geant4.4.1 distribution with gcc 3.03 and glibc 2.2.2 and get a long list of warnings like: warning: ISO C++ does not support `long long` There is no reason for these messages as one can see from the Gnu gcc mailing list (http://gcc.gnu.org/ml/gcc/2000-06/msg00362.html). My proposal is to use the gcc warning option '-Wno-long-long' in Linux-g++.gmk . Harald Vogt
The G4PhotoNuclearCrossSection.cc issue should be fixed with the patch we just released. True, the G4PhotoNuclearProcess class is missing in he doc. I've added it now for the next documentation update. Many greetings, Hans-Peter.
