Im making a game engine and i need to be able to make my engine object available to all the other classes in the other source files.
I have the engine declared as so:
Engine engine;
How would i make "engine" global so that i could use it within other classes in other source files?
Global Class Objects?
Thats not really telling me how to fix my problem thoi need to make it global
Have you really read the article? It does cover your problem.

No you don't.
If an object requires to know the engine, then simply pass the engine to the object (or the appropriate subsystem). For example, imagine a class that represents a mesh. The mesh requires access to the rendering system when it is to be rendered, but instead of using one global engine, simply pass the engine either at creation time or during rendering to the mesh.
I wouldn't mind you using globals however this kind of attitude has corrupted our codebase at work, so I took it upon myself to haunt anyone promoting the use of globals (there are VERY view cases in which globals are THE way to go).

I have a class like this:
//GameCore.h
class GameCore
{
public:
void someNormalFunction()
void daDaDa()
.....
static GameCore* Get(); //This returns a global object
}
//GameCore.cpp
GameCore *nastyGlobal;
GameCore::Get()
{
if(nastyGlobal == NULL)
nastyGlobal = new GameCore()
return nastyGlobal;
}
//otherFile.cpp
....
GameCore::Get()->PlayGame();
GameCore::Get()->Stop();
