Dear Geant4-ers, I was given a code of a program written in Geant 4 to get into it. When I started to compile it I found some incompatibilities. For example the #include <vector> was not enough, and I had to include 'using namespace std;' to get it to work. Then I wonder how some classes, where 'cout' and 'endl' were used, could work without including the library <iostream.h>. OKAY. The program uses also the graphics from Root. Afterwards, when all the errors were managed, when running it the program crashes, saying: The Segmentation Violation. I found that this crashing comes at the line runManager->Initialize(); Another supicious thing. As I said the program uses the Root (I have Root 3.05). And in the errors list (when executing the program) I see some errors when the program should use some Root libraries. But it finds them, so I think the error is not there. I don't have a clue what should I do. Do some of you know where the problem is or any comments on this? Excuse me if my question was childish. I've never programmed in Geant before. But I like the case that it is in C++!!! Have a Nice Work! Kind Regards, Oleg.

This is standard C++ syntax. > Then I wonder how some classes, where 'cout' and 'endl' were used, > could work without including the library <iostream.h>. OKAY. To use standard C++ you need to include <iostream> for std::cout and std::endl. Again, standard C++ syntax. > The program uses also the graphics from Root.

It is not clear from this report what is problem ... If errors are originated from Root libraries, it is more likely there's a problem in Root, or in the way it has been interfaced to Geant4.
