I'm having these errors with serialization with the cvs of today ..\..\..\..\boost\boost\archive\detail\oserializer.hpp(488) : error C2375: 'boost::archive::detail::instantiate_pointer_oserializer' : redefinition; different linkage ..\..\..\..\boost\boost\serialization\export.hpp(63) : see declaration of 'boost::archive::detail::instantiate_pointer_oserializer' ..\..\..\..\boost\boost\archive\detail\iserializer.hpp(503) : error C2375: 'boost::archive::detail::instantiate_pointer_iserializer' : redefinition; different linkage ..\..\..\..\boost\boost\serialization\export.hpp(58) : see declaration of 'boost::archive::detail::instantiate_pointer_iserializer' Was working correct with the cvs from two weeks ago. Is it correct to delete from the class definitions these MACROS: BOOST_IS_ABSTRACT(base_class); BOOST_CLASS_EXPORT(derived_class) ? -- Felipe Magno de Almeida Developer from synergy and Computer Science student from State University of Campinas(UNICAMP).
