I hope this helps.

Anyone???
In the boost code I found this comment:
// note:if this exception is thrown, be sure that derived pointer
   // is either regsitered or exported.
How can I register a class????????

Just make the test without a pointer ant it works just fine.
I've looked at the documentation and it only refers to this problem on
derivated classes! But I'm not deriving any class. I'm just including
the ponter of a class :(

Ok!!!
Now I'm getting unregistered_class exceptions when trying to seryalize
a class that has another class. Like:
class C : public Serializer
{
        typedef Serializer Parent;
public:
        std::string text;
        A* m_owner;
        int32 dasse;
        C():m_owner(0)
        {
                text = "Ola sua puta rabeta!";
                dasse = 69;
        }
void Serialize(IArchive& ar, const unsigned int version)
        {
                ar.Serialize(dasse);
                ar.Serialize(text);
                //ar.Serialize(m_owner);
        }
};
class A : public Serializer
{
        typedef Serializer Parent;
public:
void Serialize(IArchive& ar, const unsigned int version)
        {
                ar.Serialize(dumbi);
                ar.Serialize(vectorTest);
                ar.Serialize(matrix);
                ar.Serialize(testing);
                ar.Serialize((void*)test_void, sizeof(Vector3f));
        }
int dumbi;
        float dumbf;
        Vector2f vectorTest;
        Matrix33 matrix;
        C* testing;
        Vector3f* test_void;
A():dumbi(12), dumbf(69.69f)
        {
                testing = new C();
                testing->m_owner = this;
                matrix.SetIdentity();
                test_void = new Vector3f(1,2,3);
        }
A(int dumb1, float dumb2) : dumbi(dumb1), dumbf(dumb2)
        {
                testing = new C();
                testing->m_owner = this;
                matrix.SetIdentity();
                test_void = new Vector3f(1,2,3);
        }
};
If I comment the line that serializes C object from A
(ar.Serialize(testing);) everything works fine.
I can serialize Object A. And I can serialiaze the Object C to. But
when I have apoibter to C on object A It throws the unregistered_class
exception?
Why?
How can I avoid this???

Use binary_object.
