      @rtvideo said in Cross Compile qt to IMX6: I am trying to run a Qt program made in a Linux 64 bit Ubuntu desktop (18.04) on a IMX6 SabreLite that has Ubuntu 18.04 installed as well Have you set up a cross-compile environment? Is there instructions or even an SDK for such device in order to cross-compile Qt apps for it? I'm not expert on IMX6-based devices, so not sure if you have same device or not, but have you checked this Qt guide regarding IMX6 support? I know that there is a package called "libimxvpuapi" that if I could get into my .pro file and compile it, it may work on my imx6 by running the binary file. Again, not expert on those IMX6 devices, but from this official Freescale page, the libimxvpuapi library provides an API for using hardware video codecs on i.MX platforms so it doesn't look like it will help you run your Qt app built for a Linux 64 bit Ubuntu desktop (18.04) work on my imx6 by running the binary file.

      Hmm good catch! Although it turns out that I can't flick the list, because the items require some custom mouse move handling ... which reduces it to a non-interactive PathView. So, solved I guess! Thanks for pointing out the Tumbler though, and I hope my examples prove to be useful to others.

      Hi May I ask how you got this to build? I am trying to compile Qt with the following configuration (for Raspberry Pi): ./configure --prefix=/usr -release -opensource -confirm-license -c++11 -no-largefile -no-qml-debug -system-zlib \ -no-journald -system-libpng -system-freetype -system-libjpeg -system-sqlite -openssl -no-pulseaudio -alsa \ -no-sql-db2 -no-sql-ibase -no-sql-mysql -no-sql-oci -no-sql-odbc -no-sql-psql -no-sql-sqlite2 -no-sql-tds -nomake examples -reduce-exports \ -no-directfb -no-linuxfb -eglfs -no-xcb -device linux-rasp-pi-g++ -device-option CROSS_COMPILE=/usr/bin/ -sysroot / Here is my patch: diff --git a/qtwebengine/tools/qmake/mkspecs/features/functions.prf b/qtwebengine/tools/qmake/mkspecs/features/functions.prf index ef0320d..5abaecc 100644 --- a/qtwebengine/tools/qmake/mkspecs/features/functions.prf +++ b/qtwebengine/tools/qmake/mkspecs/features/functions.prf @@ -12,13 +12,9 @@ defineTest(isPlatformSupported) { return(false) } - linux-g++*:!isGCCVersionSupported(): return(false) - !isPythonVersionSupported(): return(false) - linux-g++*|win32-msvc2013|macx-clang: return(true) boot2qt: return(true) - skipBuild("Qt WebEngine can currently only be built for Linux (GCC), Windows (MSVC 2013), OS X (XCode 5.1+) or Qt for Device Creation.") - return(false) + return(true) } defineTest(isPythonVersionSupported) { -- 2.1.0 And it succeeds, but I don't get a message about WebEngine being an unsupported platform. It simply does not build that module. I tried to follow this reference here, but had no luck either: https://forum.qt.io/topic/48223/webengine-raspberry-pi/2 I am building native, not cross, on Debian Jessie. Thanks in advance, Sam

      The static build is failing inside of Yocto. All I have done to get this to fail is to change -shared to -static inside of qtbase.bb and then $ bitbake meta-toolchain-qt5. Building Qt dynamically will successfully create the SDK, but not statically. I have found someone with the exact same problem here. The plugin lib directory path is incorrect and has the cross compile prefix omitted causing problems finding the necessary libraries. I've posted my build environment and error output here.

      Hi @atessadri, I would like to know how to understand when the animation embedded in the transition is really finished. Is there any signal to catch ? Yes there is. Transition has running property so you can use the onRunningChanged signal handler inside it. Eg: Transition { ... onRunningChanged: if(!running) console.log("Stopped") } Sorry I don't have answers to your other questions.

      This maybe due to the fact that our IMX6 board does not have the plugins/mediaservice particularly the libgstmediaplayer.so. Does anyone know how to create this library? And which directory in the IMX6 do I put this if I have successfully cross compiled it?

      It depends if it's a Qt Quick application or not. If you are using widgets or doing your own custom OpenGL rendering then there will be no problem. The issue with Qt Quick is that it has its own animation system which gets driven by the default 16.66 ms on platforms where it fails to query the real refresh rate from the system. Run with QSG_INFO=1 to verify the actual value that is in use. (NB Qt 5.5 has some improvements in this area - https://bugreports.qt.io/browse/QTBUG-44971 - so it is now able to retrive the correct refresh rate on embedded platforms too)
