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

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 !
