When you report issues it's always helpful to include basic information version of boost (apparently 1.32?), platform (apparently some sort of uni*?), compiler version... Jeff

is MyClass abstract? That is, does it have a pure abstract function in it ( func() = 0;)? Check BOOST_IS_ABSTRACT in the documentation. Robert Ramey Damien * wrote:

MyClass is not abstract. it has virtual functions, but no pure virtual functions. if i use that macro however, the error goes away, but i then get this runtime assertion failure when it tries to serialize out. /usr/local/include/boost-1_32/boost/archive/detail/oserializer.hpp:432: static void boost::archive::detail::save_pointer_type<Archive, TPtr>::polymorphic<T>::save(Archive&, const T&, const boost::archive::detail::basic_pointer_oserializer*) [with T = MyClass, Archive = boost::archive::binary_oarchive, TPtr = MyClass*]: Assertion `__null != bpos_ptr' failed.
Hmm, are we serializing through a base class or a derived class? If through a base class has the derived class been "registered" via register(..) or via BOOST_CLASS_EXPORT? Robert Ramey Damien * wrote:

Robert Ramey
that appears to have done the trick. thanks a bunch. i dont understand why i had to use the BOOST_IS_ABSTRACT macro for a class that wasnt abstract though. oh well. thanks again.
