some compiling problem with the new release geant4-v11.0.2

[giovixo]

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

At the moment the solution I found is to downgrade my geant installation to geant4.10.07.p03

Try this:

#include "g4root_defs.hh"
#include "G4AnalysisManager.hh"

If G4AnalysisManager is being a pain to work with (it was for me), try

#include "G4RootAnalysisManager.hh"

For the Cerenkov light in tutorial 6, you need to set the energy array to a monotonically increasing order, so the smallest value first then lastly the largest. (just swap around the values the tutorial gives)

In addition to swapping to the updated header files as mentioned above...

In Geant4 v11 you need to add 'return true' after the G4cout command in detector.cc - make sure youre return is after the Fill Ntuple commands otherwise your .root file will be empty and gets deleted upon close.

I also recommend adding the following in run.cc after defining *man. This will allow you to see the open/write/close of your .root file in terminal output.

man->SetVerboseLevel(1);

Hi,

I recently started learning Geant4. I use version "GEANT4-11.0.0". When I try to compile and run the files in the repository, I get the following error, how to rectify this ?

Thanks in advance for your valuable suggestions.

In the detector.hh file make sure to have
#include "G4PhysicsOrderedFreeVector.hh"

@prb1509 I tried adding the header file you told in the detector.hh file, but I again get errors :

Hello @Gins2104,
The OP had the same issue as you can see. The easiest fix would be to use a different version of Geant4. 10.7 was the version the code was written for, so I would suggest you do the same.
If you have a strong reason to stick to v11, however, then we can work through it later.
