What steps will reproduce the problem? 1. svn checkout http://chipmunk-physics.googlecode.com/svn/trunk/ chipmunk-physics-read- only

2. compiling RUBY BUNDLE: ruby extconf.rb

What is the expected output? What do you see instead?

I got this message: cp: ../src/constraints is a directory (not copied).

I resolve with:

-system 'cp ../src/* ./' +system 'cp -pR ../src/* ./'

But now when I run make:

gcc -I. -I/usr/local/lib/ruby/1.8/i686-darwin9.5.0 -I/usr/local/lib/ruby/1.8/i686-darwin9.5.0 -I. -D_XOPEN_SOURCE -D_DARWIN_C_SOURCE -fno-common -D_XOPEN_SOURCE=1 -fno- common -pipe -fno-common -std=gnu99 -ffast-math -c chipmunk.c In file included from chipmunk.h:75, from chipmunk.c:24: constraints/cpConstraint.h:56:35: error: cpBreakableConstraint.h: No such file or directory make: * [chipmunk.o] Error 1

What version of the product are you using? On what operating system?

MAC OSX 10.5.5, ruby 1.8.7 installed in /usr/local/bin

Best regards

Please note that is only in the svn checkout (the 4.1.0 work well)

all the best

Sorry for the blast from the bast. I've been unintentionally avoiding the issue tracker, but I figured I should give these issues some closure.

The Ruby extension in 5.2 and trunk should compile on Linux/OS X by using CMake. Alternatively, there is a more actively maintained FFI based version. http://github.com/erisdiscord/chipmunk-ffi
