std::vector::iterator iter;
needs to be changed to
std::vector[Observer*]::iterator iter;

(hoping that brackets won’t get corrupted here)

Hi, I just found out how to compile the code in MVC++ 2008/2010. The following changes must be made:

#include<iostream] //needed for the “couts”

//then from
std::vector observers;

//to
std::vector<Observer*] observers; //needs to be a pointer, coz you can’t instantiate an abstract class

//from
std::vector::iterator iter;

//to
std::vector”

Those were my two cents. Hope this helps someone else out there.

The world needs more people like you :) I'll do more research and hopefully get to compile that code under MVC++. Greetings from Costa Rica!

I have had very little experience with Microsoft Visual C++ nor do I have a windows machine so I cant be any help there. I would firstly confirm with an example how the generic template syntax works under Visual C++. I would also check the way to iterate over vectors as there seems to be an issue there as well. Sorry I can not be more help. Well I can confirm this compiles with gcc the GNU c++ compiler.
