G4SiPM Visualization GUI window

Hey @ cherifchergui

The code uses macros G4VIS_USE.

In Geant4, the macros G4VIS_USE was traditionally used to conditionally compile visualization and user interface components. However, starting from Geant4 version 10.6, this macro has been deprecated and are no longer defined by default.

See: G4UI_USE and G4VIS_USE retired in 4.10.06?

Please take a look at examples/documentation on how to properly define the GUI.
