ObjectiveChipmunk - undef symbol for ChipmunkObjectFlatten

Postby mikelaurence » Thu Sep 15, 2011 12:15 am

I just grabbed Chipmunk and have been wrapping my head around the demo Objective Chipmunk code (using the simulator .a build).

Everything was going smoothly and building until I added the ChipmunkObjectFlatten command to my object. Now I get a "Undefined symbol for architecture i386" error via the linker.

Is there an issue with the .a file, or did I miss a step somewhere?

Thanks very much for the help - can't wait to finish up my test and get to the real deep physicky stuff! :D

O_o That is bizarre that that is the only missing symbol.

My last guess, are you using Objective-C++? That C function prototype is not wrapped in an extern C block, which is the only thing I can think of that would cause the function to be the only thing not found.

There were some cpVect functions that were complaining when I wrapped my main ObjectiveChipmunk.h import with "extern C", so I moved the ChipmunkObjectFlatten definition into its own ChipmunkC.h file and wrapped that - now everything is compiling and physicking around.

Thanks for the support! I'm pumped to get started with some new, non-C++ physics :D
