PdLinkSample Xcode compilation issues

[Audionomy]

Hi,
I haven't been able to build and run the PdLinkSample project in XCode. I keep getting "undefined symbols" compilation errors (see below). I have carefully checked my library and header search paths. I have tried various C++ compiler options in XCode. No luck so far. Has anyone had the same issues? Sounds like I am missing a particular setting somewhere, but which one?

@Audionomy You need to request access to the LinkKit SDK for iOS http://ableton.github.io/linkkit/ and then include in PdLinkSample

ok thanks

[headkit]

does not work anymore. I get the errors

"Implicit declaration of function 'ABLLinkCaptureAppTimeline' is invalid in C99"

and

".....pd-for-ios/pd-for-ios/PdLinkSample/PdLinkSample/ViewController.m:41:5: Use of undeclared identifier 'ABLLinkTimelineRef'; did you mean 'ABLLinkTimeAtBeat'?"

for the line
ABLLinkTimelineRef timeline = ABLLinkCaptureAppTimeline(linkRef);
in ViewController.m
