Description Zahira Ammarguellat 2021-12-15 21:42:23 CET 
Compilation with clang on Windows using VS2019 generator, is generating this error:
 error LNK2005: "public: virtual void __cdecl TG4MoleculeShoot<class G4Track>::Shoot(class G4MoleculeGun *)" (?Shoot@?$TG4MoleculeShoot@VG4Track@@@@UEAAXPEAVG4MoleculeGun@@@Z) already defined in G4MoleculeGun.obj 

The pure virtual function Shoot is instantiated twice. The first one is in 
G4shared_ptr<G4MoleculeShoot> output(new TG4MoleculeShoot<TYPE>);
and the second one is in the explicit specialization 
template<>
void TG4MoleculeShoot<G4Track>::Shoot(G4MoleculeGun* gun).
