Hi Miguel, you can find what you seek in the documentation under Reference, Serializable Concept, Pointers, Pointers to Objects of Derived Classes. Two possibilities: * eiter call ar.register_class<A>() * or use the macro BOOST_CLASS_EXPORT(A) Have fun, Christian Pfligersdorffer Software Engineering EOS GmbH

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??? On 1/12/07, Robert Ramey <ramey@rrsd.com> wrote:
Use binary_object.
