Hi, in these days i'm trying to port a newer QtWebKit to Haiku, QtWebKit 2.2.0. Using haikuporter i have installed all dependencies. Running /boot/develop/QtWebKit-2.2.0/Tools/Scripts/build-webkit --qt at the first time, after about half hour of work, i have found some errors which i have solved by applying these patches: https://bug-92264-attachments.webkit.org/attachment.cgi?id=154643 (here i have added Haiku) https://bug-41953-attachments.webkit.org/attachment.cgi?id=61034 All goes fine for about one hour, and now i'm stuck at this error which i don't know how to solve: ../../../../Source/JavaScriptCore/wtf/NullPtr.h:48:1: warning: identifier 'nullptr' will become a keyword in C++0x [-Wc++0x-compat] ../../../Source/WebCore/xml/XPathGrammar.y: In function 'int xpathyyparse(WebCore::XPath::Parser*)': ../../../Source/WebCore/xml/XPathGrammar.y:188:69: error: 'deletePredicateVector' was not declared in this scope make[1]: *** [obj/release/XPathGrammar.o] Error 1 make[1]: Leaving directory `/boot/develop/QtWebKit-2.2.0/WebKitBuild/Release/WebKit/qt' make: *** [sub-WebKit-qt-QtWebKit-pro-make_default-ordered] Error 2 /boot/develop/QtWebKit-2.2.0/Tools/Scripts> "'deletePredicateVector' was not declared in this scope" sounds to me like some missing dependencies, right? How can i get rid of this error? Complete output: http://pastebin.com/kcZw91UD Best regards. -- Giovanni.
