You can force weak linking for that particular framework using -weak_framework AVKit instead of just using the normal “-framework”. Note that you will need to make sure that the functions and classes you’re going to use actually exist if you rely on weak linking. See https://developer.apple.com/library/mac/documentation/MacOSX/Conceptual/BPFrameworks/Concepts/WeakLinking.html Kind regards, Alastair. -- http://alastairs-place.net ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
