I don't see any difference.

I'm sorry if it came across as some sort of test, that was not my intention. Here:


/System/Library/Frameworks/Accelerate.framework/Headers/Accelerate.h
/System/Library/Frameworks/vecLib.framework/Headers/vBasicOps.h (and others)


In both cases the headers you include exists as "top level" headers in the framework bundle. If you check the path to the version of the vecLib framework that you've added to Xcode you'll probably (?) find that you've referenced the one in /System/Library/Frameworks (and not the one inside the Accelerate framework), and that's why the short-hand notation for the include statement works like you wrote it. At least that's my layman explanation - someone please correct me if I'm off track...

In any case, as the Accelerate header includes the other two, you probably only need that one.

Btw. Isn't it weird that Apple have two separate copies of the vecLib framework installed?
