I have the following code and it gives a linker error on MS vc++ 6.0.

Can anyone help in this regard?
Implement the constructor.

Thanks everyone, and by the way i was just thinking of moving the
cons, copy cons and operator function to private section, wouldn't
that also server the purpose of singleton implementation?
Currently there's no real difference between having them protected and
private, you'd still have to implement the constructor. The only
difference would be if you inherit from Singleton, unless you plan to do
that you can have the private.
