David, To call CLHEP classes from CINT, you must have the corresponding CINT dictionary. Some people have been courageous enough to build this dictionary. May be someone will respond to your request! Note that most functions/classes in CLHEP have an equivalent (if not better) functionality in ROOT itself. In this case, you do not have to worry generating a dictionary. You can see an example of convolution between a landau and a gaussian in the standard ROOT tutorial langaus.C. You can adapt it to your case.
