-Woverloaded-virtual - warnings

The warning means that: When you are not using dynamic dispatch then your derived class object can only call,

void exception()
and it will hide all same named methods of the Base class intermediate.

In order that your derived class object can call all the same named methods in base class intermediate, You need to add the following line to your derived class.

using intermediate::exception; Ofcourse, You are in best position to decide if this is a problem or not.

slows down the eclipse build process and debugging the own code becomes annoying after a while...

Warnings are not bugs by definition.

Workaround : Remove -Wall from the compiler options on macs. (This is not part of wall on Linux).

[Samir Menon]

This is a fairly involved issue. Primarily affects classes where the subclass actually extends the superclass, and the superclass' functions just "don't" work for the subclass.

Ie. The subclass functions must be overloaded.

There are two possible fixes:

• Make sure the overloadable functions are not virtual (probably the way to go)
• Make the overloadable functions private/protected in the subclasses

Need some more investigation to see which method will work best.

[Samir Menon]

This needs some attention.

It's a stale bug and we're not looking to support macs for now.
