Sensitive Detectors

Getting Started
1

Hello,
I am trying to build my detectors as follows:

void DetectorConstruction::ConstructSDandField()
{
G4SDManager* SDman = G4SDManager::GetSDMpointer();
G4String SDname;

G4VSensitiveDetector* AISTHPGe = new DetectorSD(SDname="/AISTHPGe1");
SDman -> AddNewDetector(AISTHPGe);
Ge_Detector -> SetSensitiveDetector(AISTHPGe);

G4VSensitiveDetector* LaBrSDDetector = new DetectorSD(SDname="/LaBrSDDetector1");
SDman -> AddNewDetector(LaBrSDDetector);
LaBr_Detector -> SetSensitiveDetector(LaBrSDDetector);
}

But I always have this error:

Can you guide me to the mistake!
Thank you a lot in advance for any suggestions!

You’re missing #include "DetectorSD.hh" in your DetectorConstruction.cc file. If DetectorSD() is a function, rather than a class, then you don’t use “new.”

DetectorConstruction.cc (4.7 KB)

I get almost the same error.
Can you please check the attached file!!
