I just changed template<class Archive, class T> inline void save(Archive& ar, derived<T>& obj, const unsigned int version) { to template<class Archive, class T> inline void save(Archive& ar, const nderived<T>& obj, const unsigned int version) { at line # 91, and I removed the l // from line #85 compiled and ran with VC 7.1 Seemed to work find. the output was: ------ Build started: Project: test_zexp, Configuration: Debug runtime-dynamic text_archive Win32 ------ Linking...

The code compilation fails with "boost::STATIC_ASSERTION_FAILURE<x>" at the "save_override" function in "basic_xml_oarchive.hpp". I tried "BOOST_SERIALIZATION_BASE_OBJECT_NVP(obj)" and "boost::serialization::base_object< <base<T> >(obj)" and I am not able to compile the source code. Base object serialization macros are not able to deduce the template argument list.

I am trying to serialize a derived template class. template<class T> class base {}; tempate<class T> class derived : public base<T> {}; I am trying to serialize 'derived' and have tried many different things. I am unable to serialize the inherited template classes. For some reason the code calls (1) 'derived::Serialize' (2) 'base::Save' and never executes 'derived:: Save' and doesnot serialize the 'derived' object properly. I am attaching the source code (SerializeTemplates.cpp) and the output(output.txt) of the program. I am using MSVC7.1, debug mode, Boost 1.33, Spirit 1.8 It will be great, if somebody could point out what I am doing wrong.
