5.3.1 ABI change #12

Closed mieko closed 13 years ago

mieko commented 13 years ago

There's an unfortunate arbitrary ABI change in Chipmunk r495 that appears to have made it into 5.3.1+

http://code.google.com/p/chipmunk-physics/source/diff?spec=svn495&r=495&format=side&path=/trunk/include/chipmunk/cpBody.h&old_path=/trunk/include/chipmunk/cpBody.h&old=494

As you can imagine, this was pretty weird to track down. Started getting NaNs after setting v_limit.

BTW, I originally wrote a patch that split CP::VERSION into components, but I was trying to be non-invasive. At your discretion how far a simple string compare will hold against Chipmunk's versioning scheme.

Thanks, -M

applied, spoke with Scott (author of chipmunk, waiting to see how he handles the fact that he broke the API) Thanks for the contribution to chipmunk-ffi; what are you using it for?
