Yep that's what It was, thanks for the help, I guess I should have looked further into the error messages. Since however I didn't want to modify the implementation of the class, I used the const_cast on the constant members which worked just fine. I do have a couple of more general questions: 1) What is the benefit/reason for using BOOST_SERIALIZATION_ASSUME_ABSTRACT as it is used in the tutorial demo.cpp for an abstract class (it obviously works without it)?
the "is_abstract" type trait doesn't work on all platforms. BOOST_SERIALIZATION_ASSUME_ABSTRACT is a no-op on those platforms where "is_abstract does work and a specialization on those platforms where it does ... or something like that. It permits your code (and test code) to be run on all compilers.
2) In the case where the base class has no serializable members (like it is the case for the my "base" class), I get a warning for unused parameter ar as expected, however is there any defacto way to bypass that ?
You can get around that by explicitly defining a void_cast specialization. I think one of the test does that to avoid bogus warning. But it doesn't really add anything except shutting down the warning. Robert Ramey
