Thread: Weird class problem!

I am having a class named EFX_Camera defined like this:

Code:

struct EFX_CameraSystem
{
    EFX_VECTOR3 position;
    EFX_VECTOR3 lookat;
};

class EFX_Camera
{
    public:
    void SetPosition(EFX_VECTOR3 Pos);
    void SetLookAt(EFX_VECTOR3 LookAt);

    private:
    EFX_CameraSystem   system;
};

The EFX_VECTOR3 is a class with a constructor EFX_VECTOR3(float x, float y, float z) that passes the parameters values in the class member variables f_x, f_y, f_z.

But I get the error EFX_Camera no approproate default constructor available. (VC++6)

I do not need a constructor for this, but even if I add one, I get this error: EFX_CameraSystem no appropriate constructor available.

Please help, I do not know how to fix this. It is weird.
