[xsd-users] Linking errors (not Xerces, I believe) with date_time types in VS2010

[James & Veri Martin]

Hello,
I am setting up xsd usage on a project for the first time.  I followed the Visual Studio 2010 configuration steps and have added the Xerces library to my link path and libs.  However, when I build my project it appears that any schema element typed as xsd:dateTime the generated code for those elements produces this error message:
error LNK2001: unresolved external symbol "public: __thiscall xsd::cxx::tree::date_time<wchar_t,class xsd::cxx::tree::simple_type<class xsd::cxx::tree::_type> >::date_time<wchar_t,class xsd::cxx::tree::simple_type<class xsd::cxx::tree::_type> >(class std::basic_string<wchar_t,struct std::char_traits<wchar_t>,class std::allocator<wchar_t> > const &,class xercesc_3_1::DOMElement const *,class xsd::cxx::tree::flags,class xsd::cxx::tree::_type *)" (??0?$date_time at _WV?$simple_type at V_type@tree at cxx@xsd@@@tree at cxx@xsd@@@tree at cxx@xsd@@QAE at ABV?$basic_string at _WU?$char_traits at _W@std@@V?$allocator at _W@2@@std@@PBVDOMElement at xercesc_3_1@@Vflags at 123@PAV_type at 123@@Z)

...what am I doing wrong?
Thanks,James
