Hello Roger, The '#progma link C++ function' statements does not request function return type because return type does not contribute identifying overloaded functions. You simply need to specify scope, name and argument types of the function. So, it goes as follows. #pragma link C++ function operator<(UnaryFunction<PhysicsObject*>&,double); Please refer to cint/doc/ref.txt and look for '#pragma link' section. I'll attach a small example code.
