No problem, what about the issue of explicit instantiations with seperate template .ipp files vs. header only template files? The only reason I see for the explicit instantiations is that some template class function definitions are unexposed in headers.
looking at polymorphic_text_oarchive.hpp I only see a typedef. So I don't see any explicit instantiation of polymorphic_text_oarchive unless it's a side effect of BOOST_SERIALIZATION_REGISTER_ARCHIVE which isn't used in the demo.
I should have been more specific. I was referring to: ./libs/serialization/src/polymorphic_iarchive.cpp ./libs/serialization/src/polymorphic_oarchive.cpp I'll query the dev list on the pros/cons of explicit instantiations with seperate template .ipp files vs. header only template files, right now I'm leaning against the former. If there is a general consensus that explicit instantiations are not needed, then I'll open a trak item to do away with them in the serialization/archive libraries and add what researched results I've come up with. -Mostafa
