Error ctor is not defined?

No, they don't mean the same. The latter creates a temporary, anonymous Poco::URI::URI object inside the URI constructor.

Declares a function inside the constructor" - it calls a function (maybe a ctor of another class), not "declares" – kol Dec 7 at 15:01 @kol: oops, thinko! Corrected the answer. – larsmans Dec 7 at 15:03.

I may be wrong, but my guess would be that this: URI(): Poco::URI::URI(); is like trying to pass an initialization list to a constructor with no implementation. On the other hand URI(){ Poco::URI::URI(); } this is clearly a constructor definition and implementation. The first one gives an error because you're "using" a constructor for initialization purpose while it doesn't properly exist.

The right way to do the following: URI() : Poco::URI(){} I was including a namespace URI that did not exist. Also: Poco::URI::URI(){} // works when using gcc compiler but not on a windows compiler.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
