[Boost-users] [boost::serialization] Cannot export any class [Re: Howto store derivedclasses through pointer to base ...]

BOOST_EXPORT must a) be invoked outside of any namespace b) not have characters like < >, :: etc in it c) refer to a complete type

That's not even the problem. I extended my example from the last thread by a simple class A - no template, no namespace - and it reproduces the problem. Please have a look at the attachment. Other question: My main problem is, that derived classes are not stored through (smart-) pointer to base. Will this problem be resolved when I'll be able to export, or what's the problem there and what's "BOOST_CLASS_EXPORT" for? Is it only for assigning a name? Then, do I really need it (because my serialiser does neither care about, nor stores meta information)? Thank you Regards Marc
