=Known Issues – Qt 5.4.0=


==All platforms==
* Check that your system meets [http://doc-snapshot.qt.io/qt5-5.4/gettingstarted.html#platform-requirements Qt’s requirements] ''[doc-snapshot.qt.io]''
* All open issues can be found from Jira: https://bugreports.qt.io
* Installation over the existing installation not supported
** <span class="caps">QTIFW</span>-278: <span class="caps">SDK</span> 5.1.0 rc1 : installation over existing installation fails
* Examples in Qt Creator Welcome mode is empty
** Workaround: Start Qt Creator with clean settings (e.g. for temporary testing: ‘-settingspath /some/temp/dir’
* Qt Creator shows %{Qt:Version} in kit name / Qt version name
** You still use Qt Creator 3.2.2 (because you are using the online installer). Qt Creator 3.3 (that knows the placeholder) will be released together with Qt 5.4.0.
* qtmultimedia may not compile when building from source with -no-opengl. If this happens, apply the patch from https://codereview.qt.io/#/c/101817
==Linux==
* <span class="caps">QTBUG</span>-39897: Packaged libQtWebKit fails to load: conflict between (system) libxml2 and shipped libicu
** This can show up e.g. in crashes when trying to open Qt Creator’s Help, Widget Designer, or Qt Assistant.
* <span class="caps">QTBUG</span>-43205: The build on Linux is broken if you don’t have dbus header files installed or Qt cannot find them (it needs pkg-config).
==Windows==
* if you want to install a Qt for Visual Studio be sure you have the related Visual Studio installed
* Qt Creator does not support Windows XP.
** Workaround: Disable ‘Welcome’, ‘QmlProfiler’, QmlDesigner’ plugins
* Qt Creator does require a working DirectX/DirectDraw backend
** Enable Accelerated 3D support if you run Windows in e.g. VirtualBox, <span class="caps">VMW</span>are
* <span class="caps">QTBUG</span>-32864: <span class="caps">WMF</span> plugin fails to load on Windows Vista (no service found for – “org.qt-project.qt.mediaplayer”)
** Workaround: If you target Windows Vista, rebuild the plugin (qtmultimedia/src/plugins/wmf) using the Windows Vista <span class="caps">SDK</span>.
* The Just-in-time compiler is disabled in QtQml – this will be fixed in Qt 5.4.1.
==WinRT / Windows Phone==
* Please install Visual Studio 2013 Express Update 3 (or 4) for '''Windows''' (Professional/Ultimate versions are also supported, as long as the Windows Store App components are installed)
* Note that not all mobile related modules are supported (e.g. bluetooth, etc)
* <span class="caps">QTBUG</span>-41753: When deploying to Windows Phone in release mode, VS fails to find the Qt plugins. Two workarounds (one permanent and one per-project) are detailed on the bug report.
==Mac OS X==
* Qt binary packages: qmake may stop with an error claiming the macosx10.8 <span class="caps">SDK</span> can’t be found.
** Workaround: Edit clang_64/mkspecs/qdevice.pri, comment out the <span class="caps">QMAKE</span>_MAC_SDK line.
* <span class="caps">QTBUG</span>-31724: can’t debug into qt libs on Mac (it hasn’t worked since 5.0.0)
** Workaround: Compile Qt on your own (configure -developer-build provides both release and debug libs)
* <span class="caps">QTBUG</span>-35211: Apps using Qt WebKit 2.0 are not deployable on Mac OS X (QtWebProcess fails to deploy/start)
* <span class="caps">QTBUG</span>-35317: Qt Quick1 apps that use Qt WebKit 1.0 fail to deploy on Mac OS X
* <span class="caps">QTBUG</span>-35506: Qt Quick Controls applications launched using qmlscene might not display the menubar until they lose and regain focus
==Android==
See “[[Qt for Android known issues]]“
==iOS==
See “[[Qt for iOS known issues]]“
==BlackBerry 10==
See “[[Qt5 Status on BlackBerry10|Qt5 Status on BlackBerry 10]]“
==<span class="caps">QNX</span>==
See “[[Qt Status on QNX|Qt Status on <span class="caps">QNX</span>]]“
==QtWebEngine==
* <span class="caps">QTBUG</span>-41611: macdeployqt on <span class="caps">OSX</span> must be run with a non-empty -executable= command line switch to force @loader_path install names in the bundle instead of @executable_path.
* Building on <span class="caps">OSX</span> currently requires at least XCode version 5.1. '''This will remain a requirement for Qt WebEngine. Changing it would require significant changes to the Chromium code base that are going against the direction Chromium is being developed.'''
* Building on Windows currently requires Visual Studio 2013 or Visual Studio 2013 Express Edition '''This will most likely remain a requirement for Qt WebEngine. Changing it would require significant changes to the Chromium code base that are going against the direction Chromium is being developed.'''
* On Windows, you need to add the gnuwin32/bin directory from your Qt checkout to your <span class="caps">PATH</span> when doing shadow builds.
* <span class="caps">QTBUG</span>-43264: You should not run more than one instance of any given QtWebEngine using application. Each instance expects to the be sole user of its disk-based persistent data, and may cause corruption when two are using it at the same time. Running two different applications using QtWebEngine is not a problem as they use different data paths.
