Can anyone help me with this Apple Mach-O Linker Error?

Question

I know this is not a programming question, and I need help with setting up Chipmunk. I have already wasted half a day on this and tried solutions from other similar postings...

But can anyone help me with the following errors ?

Answer 1

You're not linking against the library that contains cpSpaceStep , cpInitChipmunk or cpSpaceNew . It looks like that is cocos2d. Make sure you've got the cocos2d library added to your project and that it is part of the "Link binary with libraries" build phase.

Answer 2

Delete the library and add once again. I have faced this issues couple of times. Hope this helps.

Answer 3

I got the issue resolved with just initializing a project under chipmunk. I had write/copy all the methods from my previous class, and it took some time to do that... but it was worth it in the end !
