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.
