Abstract base class problems with CINT

Hi, I have an abstract base class and an associated
derived class which I'd like to use in ROOT CINT. I have
no compile-time errors/warnings. However, I cannot
load the shared library into ROOT because the __vtbl
for the abstract base class is undefined. When I look
in the shared library with nm, I see that not only is
the __vtbl undefined, but so are the Class, Dictionary,
ImplFileLine, and ImplFileName member functions.
Both the base and derived classes have the ClassDef
statements (with input number=0), and the derived
class implementation file has its ClassImp.
If anyone has suggestions for something I can look at
or I've left out, please let me know. Thanks,
-Gene Van Buren
