Re: [Boost-users] Vector of Polymorphic Pointers

Thank you so much!! I moved the register calls just after the archive is created and it worked! Thanks again!! You have literally saved me hours of work!! Thanks for the prompt responses! On 5/1/06, Robert Ramey wrote:

I use the vector "children" to hold pointers to both base and derived objects. I have tried registering the derived classes at the top of the serialize function call, with the use of ar.register(static_cast(NULL)).

That is probably the wrong place to put it. should be in a place that guarentees that it will be called. Try it just after the archive is created. If that does it, you can experiment with moving it around.

I have also tried using the BOOST_CLASS_EXPORT_GUID macro to register the classes in main. Yet, I still get a unregistered class exception. Any guidance would be greatly appreciated.

Note that its not enough to include BOOST_CLASS_EXPORT. It has to be included after the *archive.hpp classes that you're using. Double check that this is the case.
