Hi Frank,
In your selector.h you have teh definition of the prototypes:
Bool_t ProcessCut(Int_t entry);
void ProcessFill(Int_t entry);
but you do not have the corresponding implementation in selector.C.
Simply comment the two lines above in selector.h and you should be able to run.
ProcessCut and ProcessFill are not necessary anymore as of version 3.10/01.
