First of all, thank you for the tutorial

I got some problems compiling the code with the new geant4-v11.0.2 release

the header "g4root.hh" is not found
After a Google search it seems to me that the new header should be:
#include "G4AnalysisManager.hh" Is it true?

I got the error:
detector.cc:26:12: error: no member named 'SetSpline' in 'G4PhysicsFreeVector'

Finally, I do not see the Cherenkov light in example number 6 (but the program is compiled correctly)

Thanks a lot for any help
