OGRE Runtime Failure

I just started with Ogre, I can compile and run all of the samples, and started working on the tutorials. The code will compile and run with the following line: Code:

         mSceneMgr->setAmbientLight( ColourValue( 1, 1, 1 ) );

The code compiles fine, but while the following lines are in the code it fails on execution: Code:

         Entity *ent1 = mSceneMgr->createEntity( "Robot", "robot.mesh" );
         SceneNode *node1 = mSceneMgr->getRootSceneNode()->createChildSceneNode( "RobotNode" );
         node1->attachObject( ent1 );

The tutorial link is: http://www.ogre3d.org/wiki/index.php/Basic_Tutorial_1 It doesn't generate a log unless I remove the last three added lines of code, recompile, and run it. I'm using codeblocks and minGW by the way I can also get at the error report data if I need to look for something. I did notice some references to exceptions.
