I'm not sure it would be acceptable, because updated QtWebKit requires full C++11 support in the compiler (gcc >= 4.9, 4.8 possible with disabling some features, or with code changes, which were not done yet). Also, there are differences in supported platforms and system requirements. macOS: One user reported that QtWebKit TP5 built for OS X 10.9 target is working fine on OS X 10.7, however the oldest officially supported version is 10.10 (as in upstream). I'm pretty sure that WK2 IPC with Mach ports will break when compiling for older targets, though it should be possible to switch to unix sockets just for 5.6. Windows: Windows XP support seems to be feasible, if needed, without new MediaFoundation-based player. Will require backporting Conan-related patches in qt5.git to 5.6 branch. Linux: GStreamer 0.10 is not supported, so official builds with video will have to use QtMultimedia MediaPlayer implementation. I'm not sure about QNX support in QtWebKit 5.6, it is skipped in CI now because of missing ICU. However, I guess it will be possible to reintroduce QNX support if there are interested folks here, at least Widgets API. All platforms will need to have cmake >= 2.8.12, this might reduce testing coverage for older cmake versions in 5.6 > > Thanks for your efforts on this! > > Regards, > -- > Sérgio Martins | sergio.mart...@kdab.com | Senior Software Engineer > Klarälvdalens Datakonsult AB, a KDAB Group company > Tel: Sweden (HQ) +46-563-540090, USA +1-866-777-KDAB(5322) > KDAB - The Qt, C++ and OpenGL Experts -- Regards, Konstantin _______________________________________________ Development mailing list Development@qt-project.org http://lists.qt-project.org/mailman/listinfo/development
