[odb-users] Issue getting relashonships off the ground

[Brian Bourke-Martin]

I have a very simple relationship setup which I cannot get the odb output
to compile and it's giving me the below compiler error.  I am using Qt
smart pointers to implement the relationship and I always seem to be
running into the same error no matter how many permutations I go through.

here is the the parent class

    #ifndef PART_H
    #define PART_H

    class Part;

    #pragma db object
    class Part{

Any help which could be given would be great!
