Thanks for your reply, all is ok now. But i need some explanation about understanding static_warning. The warnings are : ------------------------------ ../boost/mpl/print.hpp: In instantiation of ?boost::mpl::print<boost::serialization::STATIC_WARNING_LINE<98> >?: ../boost/serialization/static_warning.hpp:92: instantiated from ?boost::serialization::static_warning_test<false, 98>? ../boost/archive/detail/check.hpp:98: instantiated from ?void boost::archive::detail::check_object_tracking() [with ... ../boost/archive/detail/oserializer.hpp:295: instantiated from ?static void boost::archive::detail::save_non_pointer_type<Archive>::invoke(Archive&, T&) [with T =... ../boost/archive/detail/oserializer.hpp:507: instantiated from ?void boost::archive::save(Archive&, T&) [with Archive = boost::archive::text_oarchive, T = ... ../boost/archive/detail/common_oarchive.hpp:62: instantiated from ?void boost::archive::detail::common_oarchive<Archive>::save_override(T&, int) [with T = .. ../boost/archive/basic_text_oarchive.hpp:75: instantiated from ?void boost::archive::basic_text_oarchive<Archive>::save_override(T&, int) [with T = ... ../boost/archive/detail/interface_oarchive.hpp:64: instantiated from ?Archive& boost::archive::detail::interface_oarchive<Archive>::operator<<(T&) [with T = ... ../testEXE/test.cpp:118: instantiated from here ../boost/mpl/print.hpp:55: warning: comparison between signed and unsigned integer expressions ------------------------------ In fact, i think that this warnings are the consequences of non const object serialization. But i'm not sure... Best regards, Damien. Robert Ramey <ramey@rrsd.com> a écrit :

Hi all,
First problem: -------------- i have this warning. "...... boost/mpl/print.hpp:55: warning: comparison between signed and unsigned integer expressions"
the serialization library used this to indicate usage of the library which is permited though probably not a good idea. Check the compile error listing to find what calls this. This should show some place where BOOST_SERIALIZATION_STATIC_WARNING is invoked. There you should find an explanation of why such a warning was emitted.
Second problem: --------------- I want to serialize a template derivate class like this:
//////////////////////////// class Base { private: friend class boost::serialization::access;
template<class Archive> void serialize(Archive &, const unsigned int ) { } };
template<typenmame T> class Child: public Base { private: friend class boost::serialization::access;
template<class Archive> void serialize(Archive &ar, const unsigned int ) { ar & BOOST_SERIALIZATION_BASE_OBJECT_NVP(Base); } };
BOOST_CLASS_EXPORT_GUID(Child<int>, "Child")//don't work ///////////////////////////
The macro "BOOST_CLASS_EXPORT_GUID" don't work with template class. Is there a way to do this ?
I would guess that the <> characters are some sort of problem. Try typedef Child<int> Child_int
BOOST_CLASS_EXPORT_GUID(Child_int, "ChildInt) // remember the name has to be unique!!
Also there is a track item with a suggestion on how to implement the equivalent of:
BOOST_CLASS_EXPORT(Child<int>)

Thank you, Regards, Damien.
