Please help, or point me where should i read about it. What is this versioning and why my code was compiled with boost 1.39 will get compilation errors in 1.43?
Code:
#include <list>
#include
#include
#include
#include
#include
#include
#include
...
typedef boost::variant <__int32, unsigned __int32, std::string, std::wstring > param_t; // note: I've tried to use boost::int32_t and others, result is the same
typedef std::list< param_t > params_list_t;
...
class instruction
{
public:
...
private:
friend class boost::serialization::access; /**< Make accessible private members for boost serialization */
void save (boost::archive::xml_oarchive& ar, unsigned int version) const;
void load (boost::archive::xml_iarchive& ar, unsigned int version);
BOOST_SERIALIZATION_SPLIT_MEMBER()
private:
...
params_list_t m_params; /**< List of parameters */
};
BOOST_CLASS_IMPLEMENTATION(instruction, boost::serialization::object_serializable);
BOOST_CLASS_TRACKING(instruction, boost::serialization::track_never)
BOOST_CLASS_IMPLEMENTATION(nvp<instruction>, boost::serialization::object_serializable)

BOOST_CLASS_VERSION(param_t, 1)
BOOST_CLASS_VERSION(params_list_t, 1)
BOOST_CLASS_IMPLEMENTATION(nvp, boost::serialization::object_serializable)
BOOST_CLASS_TRACKING(nvp, boost::serialization::track_never)

CPP file:
void instruction::save (boost::archive::xml_oarchive& ar, unsigned int version) const
{
// ...

// ...
}

This is a first error message place:
template<class T>
inline void check_object_versioning(){
typedef
BOOST_DEDUCED_TYPENAME mpl::or_<
BOOST_DEDUCED_TYPENAME mpl::greater<
serialization::implementation_level<T>,
mpl::int_serialization::object_serializable
>,
BOOST_DEDUCED_TYPENAME mpl::equal_to<
serialization::version<T>,
mpl::int_<0>
>
> typex;
// trap attempts to serialize with objects that don't
// save class information in the archive with versioning.
BOOST_STATIC_ASSERT(typex::value);
}
I have understanding about what is BOOST_STATIC_ASSERT, but I haven't any ideas about what I'm doing wrong.
Changelog reading between 1.39 and 1.43 hasn't clarified anything.
