Geant4 Modification List for VC7

 Jan 13, 2003

(Including Mods from Norman Graf's "modifications.txt" file)

• Build for Glast using a cmt requirements file
  • File used located here
  • Hand built, fragile if directory structure changes in newer versions
  • Have build both V4r1p0 and V5r0 with this file
     
• Warnings turned off due to excessive error messages:
  • 4267 which occurs due to some inconsistency between G4String and std::string
  • 4305 which occurs because of the definiton of data in G4LEnpData.hh and G4LEppData.hh in the processes\hadronic\models\coherent_elastic\include folder
     
• Errors encountered in building "vanilla" Geant4:
  • Problem encountered with CLHEP's redefinition of the abs function. This removes the system definition which defines abs for complex numbers. This results in the following errors:
    • Compiling G4VXTRenergyLoss.cc ...
      G4VXTRenergyLoss.cc
      c:\Program Files\Microsoft Visual Studio .NET\Vc7\include\xcomplex(512) : error C2782: 'T abs(const T &)' : template parameter 'T' is ambiguous could be 'float' or 'std::complex<_Ty>' with [ _Ty=float ]

    • Classes in the Parameterizations subfolder suffering this malady:
      • G4VXTRdEdx
      • G4VXrayTRadModel
      • G4VXrayTRModel
      • G4VIrregularXTRdEdx
      • G4IrregularXrayTRmodel
         
    • Classes in the Processes subfolder suffering this malady:
      • G4VXTRenergyLoss
         
    • "Ugly" fix which works:
      • Reorder includes in .hh and .cc files to make sure the definition of complex is included before the include for globals.hh which pulls in the CLHEP abs definition.
      • Don't forget to copy modified .hh files to the include folder!!
         
  • Problem encountered in compiling G4RadioactiveDecay, located in the processes\hadronic\models\radiative_decay subfolder of source:
    • Compiling G4RadioactiveDecay.cc ...
      G4RadioactiveDecay.cc
      include\G4ITDecayChannel.hh(45) : error C2146: syntax error : missing ')' before identifier 'G4Ions'
      include\G4ITDecayChannel.hh(45) : error C2275: 'G4Ions' : illegal use of this type as an expression
      ../../../../../source\particles\management\include\G4Ions.hh(49) : see declaration of 'G4Ions'
      include\G4ITDecayChannel.hh(45) : error C2059: syntax error : ')'
      src\G4RadioactiveDecay.cc(1701) : fatal error C1004: unexpected end of file found
       
    • Problem is the dynamic casting of a base class to its parent in the constructor method of G4ITDecayChannel.h (located in the same subfolder):
      
      G4ITDecayChannel (G4int Verbose, const G4ParticleDefinition *theParentNucleus, G4double theBR) : G4NuclearDecayChannel (IT, Verbose, theParentNucleus, theBR, 0.0, theParentNucleus->GetBaryonNumber(),  int(theParentNucleus->GetPDGCharge()/eplus),  ((const G4Ions*) theParentNucleus)->GetExcitationEnergy())
       
    • Solution is to modify this definition to the following:

      G4ITDecayChannel (G4int Verbose, const G4Ions *theParentNucleus, G4double theBR) :
      G4NuclearDecayChannel (IT, Verbose, theParentNucleus, theBR, 0.0, theParentNucleus->GetBaryonNumber(), int(theParentNucleus->GetPDGCharge()/eplus), theParentNucleus->GetExcitationEnergy())
       

  • Problem encountered in building G4xcitationHandler, located in the processes\hadronic\models\generator\de_excitation subfolder of source:
    • Compiling G4ExcitationHandler.cc ...

      G4ExcitationHandler.cc
      c:\Program Files\Microsoft Visual Studio .NET\Vc7\include\functional(324) : error C2440: 'initializing' : cannot convert from 'const int' to 'std::binary_function<_Arg1,_Arg2,_Result>::second_argument_type' with [ _Arg1=G4ReactionProduct *, _Arg2=G4ReactionProduct *, _Result=bool ]
      Conversion from integral type to pointer type requires reinterpret_cast, C-style cast or function-style cast src\G4ExcitationHandler.cc(348) : see reference to function template instantiation 'std::binder2nd<_Fn2> std::bind2nd(const _Fn2 &,const int &)' being compiled with [ _Fn2=std::equal_to<G4ReactionProduct *> ]

       

    • Modify G4ExcitationHandler.cc with following code:
      //cng
      G4ReactionProduct* tmp = 0;
      //cng
      theReactionProductVector->erase(G4std::remove_if(theReactionProductVector->begin(), theReactionProductVector->end(), G4std::bind2nd(G4std::equal_to<G4ReactionProduct*>(),
      //cng 0)),
      tmp)),
      theReactionProductVector->end());

      i.e. replaced 0, with G4ReactionProduct* tmp = 0;
