Download & Build Instructions

Chipmunk

1. http://files.slembcke.net/chipmunk/release/ChipmunkLatest.tgz

Chipmunk, Python API & Examples

Box2d

1. svn co https://box2d.svn.sourceforge.net/svnroot/box2d box2d
2. Download and apply this patch: http://pippin.gimp.org/tmp/box2d-build-diff.txt
3. run 'make'

If it fails with a suggestion to use the -fPIC flag, add it to Source/Makefile, line 13. So it looks like this:

CXXFLAGS=   -g -O2 -fPIC
