Hi: I am writing some non-intrusive serialization code for other c++ classes. I am trying to serialize the wxString class from the wxWidgets library. I have the following code: namespace boost { namespace serialization {
template<class Archive> void serialize(Archive & ar, wxString & str, const unsigned int version) { ar & str.ToStdWstring(); } } } I noticed the following two typedefs in the wxWidgets code: typedef std::wstring wxStdWideString; typedef std::basic_string<wchar_t> wxStdWideString; only one of these is executed. I then wrote a second unintrusive serialization class: namespace boost { namespace serialization { template<class Archive> void serialize(Archive & ar, wxString & str, const unsigned int version) { ar & str; } } } I am getting the following error, using visual c++ 2010: 1>c:\program files (x86)\boost\boost\archive\basic_xml_oarchive.hpp(92): error C2664: 'boost::mpl::assertion_failed' : cannot convert parameter 1 from 'boost::mpl::failed ************boost::serialization::is_wrapper<T>::* ***********' to 'boost::mpl::assert<false>::type' with [ T=const wxStdWideString ] Given that I have written code to serialize the wxStdWideString typedef, does anyone know what is happening? Are typedefs ignored with boost serialization. Currently using 1.47. Cheers Sean.
seems to me that all you should really need to do is to #include <boost/serialization/string.hpp> this includes serialization implemenations for std::wstring and std::string. The typedefs you've included above only create some aliases with weird upper/lower case names. This shouldn't affect anything. Robert Ramey
