Not able to view objects in Chipmunk space

Hi,

I am new to cocos2dx, I created a project where I initialized chipmunk space the initialization I did was from the init() function of the cocos2d scene. But still could not see any objects that I created. Do we need to specifically do something to load chipmunk library. I just extended the project that I created in the Cocos2dSimpleGame sample.

thanks,
