-iPhone: A native Objective-C API is included. The XCode project can build a static library with all the proper compiler settings. Alternatively, you can just run iphonestatic.command in the xcode/ directory.  It will build you a fat library compiled as release for the device and debug for the simulator. After running it, you can simply drop the Chipmunk-iOS directory into your iPhone project!

This should build a dynamic library, a static library, and the demo application. A number of people have had build errors on Ubuntu due to not having GLUT or libxmu installed.
