[Boost-users] Strange compile error with Boost.Serialization

18 Apr 2005

      Hello all,

when I compile the code below (with MSVC 7.1), I get an error telling me that
"'serialize' : is not a member of 'std::vector<_Ty>'". I will post the
exact error message below the code.

The strange thing about this is that when I change the #define TEST
line to #define TEST 1 (or 2 or 3), it compiles ok [1 means that only
the iarchive is used, 2 that the oarchive is used, and 3 that a 'B'
object is serialized instead of an 'A' object].

Is there anything wrong with the code?

Thanks and best regards,

Klaus

	}
};

	B			m_;

	template <class Archive>
	void serialize(Archive& ar, size_t i)
	{
		ar & BOOST_SERIALIZATION_NVP(this->m_);
	}
};

void save()
{
#if TEST != 3
	A object;
#else
	B object;
#endif

	std::stringstream	str;
	boost::archive::binary_oarchive	ar(str);
#if TEST != 1
	ar << BOOST_SERIALIZATION_NVP(object);
#endif
}

void load()
{
#if TEST != 3
	A object;
#else
	B object;
#endif

	std::stringstream	str;
	boost::archive::binary_iarchive	ar(str);
#if TEST != 2
	ar >> BOOST_SERIALIZATION_NVP(object);
#endif
}

int main(int, char**)

	return 0;
