Unable to run hello world program after building from cmake

[kraftpunk97-zz]

Hi. I built the library from the CMake script that is present in the main directory. I then went on to copy the hello world script from the C tutorial on this page. I got the following error...

Ld /Users/kartikeygupta/Workspace/C++/Chipmunk/ChipmunkTest/ChipmunkTest/build/Debug/ChipmunkTest normal x86_64 (in target: ChipmunkTest)

What am I doing wrong here?

Sorry, I've been sick for the last few days.

Hmm. So -lchipmunk is in there and there isn't an error about the library not being found. If you run nm on chipmunk.dylib is cpBodySetPos listed? Also, if you run lipo -i on it, does it providing x86_64 symbols?

Err, nevermind. I had my Mac handy, so I just tried it.

cpBodySetPos() is the old abbreviated name. At some point years ago I went through the API and got rid of most of the abbreviations. I think even the compatibility macros were removed a few years ago. Apparently I never updated that example. Derp. :(

Use cpBodySetPosition() instead.
