I don't understand Perl nor what is going on here, but it looks bad: [622/1038] Generating ../../DerivedSou...ces/webkitdom/WebKitDOMCharacterData.h Use of uninitialized value $type in pattern match (m//) at /home/mcatanzaro/WebKit/Source/WebCore/bindings/scripts/IDLParser.pm line 302.

I could only find two changes to IDLParser.pm near July 2015: https://github.com/WebKit/WebKit/commit/05fa8411002fefbd0a66859046f0ac4a78e3bb2f https://github.com/WebKit/WebKit/commit/1d068a4b1cc7149de5fc6fc443950fb085d004ed First one seems to be more about fixing these type of warnings. Just wanted to share what I could fine and I could be completely but just wanted to update. Thanks!
