I figured it out. For the sake of others who may find the following error message confusing: Error: abstract class object 'Foo Bar' declared FILE:foo.C LINE:x This error occurs when you try to create an object called Bar which is of type Foo, where Foo is a derived class which inherits from a base class somewhere. If there is a function in the base class that calls a function in the derived class, and if that function is not present in the derived class for any reason, Cint chokes when you try to create an object of type <derived class>, rather than when you actually call the function in the base class that calls the missing function in the derived class.
