Ensure that the serialization code is in one DLL by having some function like: MyClass * deserializeMyClass(std::istream & is); And call that from either dll. Then all the serialization magic is hidden (and instantiated) in one dll and you don't need to worry about cross-dll template/static/ARGH!

I can serialize fine by calling one function, but when I call the second it triggers an assertion in extended_type_info.cpp: // make sure that attempt at registration is done only once assert(lookup(eti) == m_self->m_map.end()); Apparently the class is registered twice, but how do I avoid that? -- Anders _______________________________________________ Boost-users mailing list Boost-users@lists.boost.org http://lists.boost.org/mailman/listinfo.cgi/boost-users
