Re: compilation issues on Py3.5, os x 10.10.5

Ok, I tried to locate the setup.py, but for the through pip download acquired pyobjc-core-3.1.1 (which I presume is the right one?), I don’t find the necessary code part.

I find similar ones, and could try patching these, but maybe it would be better if you told me what exactly you used, so I can recreate that environment more faithfully. 

Cheers,

Diez

Because of this it tries to reference a symbol that isn’t present in the SDK that is used.   The “-isysroot /“ flag in the output below explains the behavior, setup.py cannot deduce the SDK used from the sysroot parameter and therefore assumes the SDK version matches the OSX version.
