Okay so I'm seeing the same error with qtscript-4.8.6-r1 and for the same reason. A bit of searching found this: https://qt.gitorious.org/qt/qtscript/commit/8b80ca515d50967086fdebb8df746c280fadf240#src/3rdparty/javascriptcore/JavaScriptCore/wtf/TypeTraits.h Which would suggest to me that qtscript playing nice with C++11 (or at least C++0X before it became C++11) is the intended behaviour. I'm also aware that most of the focus is now of the 5.x branch of qtscript but updates to KDE are still trying to pull this version in for now and probably will be for a while until all of the KDE applications have been ported to the new framework.
