But it still does not step into the correct child. After some more reading, I guess, that I'd have to use BOOST_CLASS_EXPORT(B), but that does not compile, because B is a template class.
A, B, ... are in a namespace, let's say "abc". Now, I can write: BOOST_CLASS_EXPORT(::abc::B) But this must be outside of all namespaces. Then I get: -------------------------------------------------------------------------------- /usr/include/boost/archive/detail/iserializer.hpp:197: undefined reference to `boost::archive::detail::archive_pointer_iserializerimage::BinaryReader::~archive_pointer_iserializer()' bitsets-bitsets.o: In function `~pointer_oserializer': /usr/include/boost/archive/detail/oserializer.hpp:184: undefined reference to `boost::archive::detail::archive_pointer_oserializerimage::BinaryWriter::~archive_pointer_oserializer()' -------------------------------------------------------------------------------- What's wrong, what's missing, what do I have to do?
