don't run the example

this it the log
somebody can tell me why when run the example1.

when go to the following code , it is wrong.
how to solove the promble.


//Load the terrain
sceneMgr->setWorldGeometry("terrain.cfg");


void SceneManager::setWorldGeometry(const String& filename)
{
// This default implementation cannot handle world geometry
OGRE_EXCEPT(Exception::ERR_INVALIDPARAMS,
"World geometry is not supported by the generic SceneManager.",
"SceneManager::setWorldGeometry");
}

That's because the examples use the Old Terrain system which has been deleted in Ogre 1.8
