Nick,
Thanks for the reply.
I have about 7 bundles. Do I need to explicitly load all of my bundles
individually with CFBundle or NSBundle? Is there a way that I can
discover which ones I need to load? I have next to no documentation
with this SDK :(
Thanks,
Matt

Then it's not an application; it's a dynamic library.

They probably are if they're there. Perhaps the SDK launches these
executables.

You don't link against bundles; your code has to dynamically load them
using CFBundle or NSBundle. In order to get around the linker errors,
you need to tell the linker to ignore the undefined symbols.
You can do that by either using the -u linker flag for each undefined
symbol, which will also force you to tell the linker to flatten the
namespace, or you can use CFBundleGetFunctionPointerForName() as
described in the CoreFoundation documentation.

On PPC you should be able to load PEF bundles from Mach-O code using
CFBundle or NSBundle. I don't think that will work on Intel, though.
You just can't link Mach-O code to PEF/CFM code.

Intel binaries can't be linked against PPC binaries, so it'll have to
run under Rosetta.
