I'm trying to compile (with VS 2005) a simple example of serialization
(boost 1.34) of a polymorphic class, but I get the following compile error:
basic_xml_oarchive.hpp(83) : error C2027: use of undefined type
'boost::STATIC_ASSERTION_FAILURE<x>'
1> with
1> [
1> x=false
1> ]
Can you help me? I've read the documentation and I didn't understand the
difference with the example that I found in there.
Here is the source:

//main.cpp
#include <iostream>
#include <fstream>
#include "boost/archive/xml_oarchive.hpp"
#include "boost/archive/xml_iarchive.hpp"

class base
{
public:
base(): _a(0)
{
}
base(double a): _a(a)
{
}
virtual double f() = 0;
protected:
double _a;
//Serialitation procedure.
friend class boost::serialization::access;
template<class Archive>
void serialize(Archive & ar, const unsigned int version)
{
ar & boost::serialization::make_nvp("a", _a);
}
};

{
public:
derived(): base(0), _b(0)
{
}
derived(double b): base(1), _b(b)
{
}
double f()
{
return _a + _b;
}
protected:
double _b;
//Serialitation procedure.
friend class boost::serialization::access;
template<class Archive>
void serialize(Archive & ar, const unsigned int version)
{
ar & boost::serialization::base_object<base>(*this);
ar & boost::serialization::make_nvp("b", _b);
}
};
int main()
{
derived dc(5);
{
std::ofstream ofile("test.xml");
boost::archive::xml_oarchive oa(ofile);
oa << boost::serialization::make_nvp("test", dc);
}
return 0;
}
