Would it be possible to add to the Geant4 package a type definition of HepBoost as G4Boost? A G4Boost.hh file would look like this: #ifndef G4Boost_hh #define G4Boost_hh #include "globals.hh" #include <CLHEP/Vector/Boost.h> typedef HepBoost G4Boost; #endif // G4Boost_hh
Geant4 typedefs to CLHEP types are added only for CLHEP types which are effectively in use in the Geant4 kernel.
