OgreNewt tutorial- stuck

right I'm at this point here:

Now there's one more thing we want to add to the Application class while we're here: a frame listener. in most demos, they have you create a FrameListener class inherited from ExampleFrameListener. We'll do the same in this demo, but also add a special FrameListener just for updating and debugging the Newton world. First, setup the standard ExampleFrameListener class, in your createFrameListener() function like so:

OgreNewtApplication.cpp

void OgreNewtApplication::createFrameListener()
{
mFrameListener = new ExampleFrameListener( mWindow, mCamera );
mRoot->addFrameListener( mFrameListener );
}




however I keep getting the error

'mFrameListener' : undeclared identifier


and I have no idea how to declare it

mFrameListener is declared in ExampleApplication.h
You might forget to include this file.

mFrameListener is declared in ExampleApplication.h
You might forget to include this file.

that's just it- I did include ExampleApplication.h in all my header files and also in the actual cpp files at the top but it didn't help

never mind figured it out - my problem was that I had to change

class ogreNewttest2App : public BaseApplication


to

class ogreNewttest2App : public ExampleApplication

for it to work :
