QtScript works just great for me!</p> --- Comments --- We're aware of this issue (see http://www.pubbs.net/webkit/200909/85716). Recently some macros were added to wtf/Platform.h, including TARGETING_TIGER ( = your BUILDING_FOR_TIGER). I think the correct fix would be to use those defines in wtf/VMTags.h (replacing BUILDING_ON_TIGER). But it needs to be fixed upstream (http://bugs.webkit.org). 197987 1 vestbo 2010-03-10 04:55:34 -0800 *** This bug has been marked as a duplicate of bug 34888 ***
