[Solved] Virtual inheritance and default constructor

by


With virtual inheritance, the most derived class should call virtual base constructor, so:

struct D : C<B>     // D: ThermostatedRotorJobQueueFactoryStub
{
    D(const X& x, const Y& y) : A(this), C(this, x, y) { cout << "D constructor" << endl; }
};

But that is also true for C<B>:

template <>
struct C<B> : B
{
    template <typename... Args>
    C(Args&&... args) : A(this), B(std::forward<Args>(args)...) {
        cout << "C constructor" << endl;
    }
};
