Hi, I downloaded but have been unable to build the iPhone Box2D Testbed project - from the errors (e.g. 'const struct b2Manifold' has no member named 'm_pointCount') it seems it's an older version of the Testbed project with a newer, incompatible version of Box2D. If so, that's strange, as the Testbed comes with the Box2D download. A previous download on another machine months ago worked fine. Does anyone know where I can get a working download of the Testbed & Box2D - or instructions on how to updated the Testbed to work with the latest Box2D? Any help appreciated!
