Hi Miroslav, to make your classes known to CINT you don't have to add ClassDef/ClassImp. Just add them to the list of pragma's in a LinkDef.h file, run rootcint to make a dictionary and compile and link the dictionary with the classes. After loading the shared lib you can access these classes from the interpreter. The error in 2) might be due to not having all methods implemented. Did you forget to implement some virtual Pdf method? Cheers, Fons. Miroslav Helbich wrote: > > Hi all, > > I failed badly in adding a new class to root.
