Error: "Could not load the stdlib module"

[chankalun]

Hello I am running xCode 7.1 with OSX 10.11.1 and there is an error on in #include <gst/gst.h> on ofGstUtils.h :

Couldn't Generate Swift Representation
Error (from SourceKit):
"Could not load the stdlib module"

May I ask if there is any suggestions to fix this please?

Cheers,
Karen
