    Hi
    If you get tired fighting cross compiling, there is also the option of using
    http://www.qtrpi.com/home
    its only Qt5.7 though so might not fit your use case.

      There's also the option to download Qt and QtCreator directly to the pi via the package manager.
      The framework is limited to Qt 5.7, but as a quick entry to Qt on Pi its fine and the Pi3 is beefy enough to manage compiling projects itself.

        Hello. I want to compile Qt on raspberry pi3. I use qt-everywhere-src-5.11.0 and gcc-linaro-4.9-2015.02-3-x86_64_arm-linux-gnueabihf for cross compile....

        my config command is :
        ./configure -release -opengl es2 -eglfs -optimized-qmake -no-pch -make libs -make tools -reduce-exports -sysroot $RPI_SYSROOT -device linux-rasp-pi3-g++ -device-option CROSS_COMPILE=$RPI_TOOLCHAIN -opensource -nomake examples -nomake tests -confirm-license -xcb -skip qtwayland

        my config log is:
        Note: Dropped compiler flags '-pthread' when detecting library 'glib'.

        Note: Disabling X11 Accessibility Bridge: D-Bus or AT-SPI is missing.

        Note: Dropped compiler flags '-pthread' when detecting library 'gstreamer'.

        Note: Dropped compiler flags '-pthread' when detecting library 'gstreamer_app'.

        Qt is now configured for building. Just run 'make'.
        Once everything is built, you must run 'make install'.

        after run make command i occur with these errors:

        /home/saman/qt-everywhere-src-5.11.0/qtbase/src/plugins/platforms/xcb/gl_integrations/xcb_egl/qxcbeglwindow.cpp: In member function 'virtual void QXcbEglWindow::create()':

                @Saman19 said in Qt on Raspberry pi3:

                tforms/eglfs/deviceintegration/eglfs_kms/qeglfskmsgbmmain.cpp -o .moc/qeglfskmsgbmmain.moc
                Makefile:2849: recipe for target '.obj/qeglfskmsgbmwindow.o' failed

                That's not the error message. Please look before it for the real cause of the compilation fail - and post it here.

                You may want to check out -device linux-rasp-pi3-g++-vc4, it uses the GPU from on RPi. Note however, that your RPi sysroot needs to be up to date for Qt to find dependencies there.

                  I'm also having issues cross compiling qt 5.11.0 for rpi3, has this been solved?

                    Well, compilation works for 5.10, 5.9 - they simply compile and work. With Qt 5.11.1, I've just tried and there seems to be a bug in QGeoMap.

                    If you want to try with 5.10:
                    You have to set up your toolchain and sysroot correctly, though. Follow the guide https://wiki.qt.io/RaspberryPi2EGLFS and you should be fine.

                    Remember to get all the dependencies and to run the symlink fix afterwards. You may throw in some extra libs just to be sure:

                    sudo apt build-dep qt5-default qt5-qmake
                    sudo apt install libiconv-hook-dev libinput-dev libts-dev bluez libbluetooth-dev libgstreamer1.0-dev libegl1-mesa
                    
                    # Optionally if it somehow still does not work:
                    sudo apt install "^libxcb.*" libx11-xcb-dev libglu1-mesa-dev libxrender-dev libatspi2.0-dev libdbus-1-dev
                    

                    And turn on OpenGL driver in raspi-config,

                    Here is my compilation script, if it helps:

                    export QTVER=5101

                      Thank you so much for the reply, I think i'm also seeing the issue with qgeomap when doing 'make install' for 5.11.0. I'm trying to build qgroundcontrol for the raspberry and apparently it needs 5.11.0.
                      Do you know a solution for the qgeomap bug?

                          Hi, I've compiled 5.10.1 for the pi and it works, but when I try to open the qt-project qt-creator complains about my compiler: Unsuported Linux toolchain, only GCC 32- or 64-bit is supported.
                          I'm using "gcc-linaro-5.5.0-2017.10-x86_64_arm-linux-gnueabihf"
                          Do you know what this could be?

                            Have you added the linaro compiler in Qt Creator's settings?

                              Yes,I've created a rpi kit, where I've added a gcc compiler for C and C++ which points to the linaro compiler I used when compiled the qt sources

                                Hm so it should work. Please check if the kit really points to your cross-compiled Qt. I've made a mistake of not checking that many times already :D And Qt Creator seems to auto-set the Qt version wrongly sometimes.

                                  @sierdzio I successfully compile Qt 5.10.1 on my raspberry pi 3 using the device "linux-rasp-pi3-vc4-g++", however, after activating the OPENGL driver on raspi-cofnig, when running the qopenglwidget example, it shows the error "Failed to create service, already in use?", I checked on the internet and everybody suggest to disable the vc4 drivers to get rid of the error, however, if I do that the eglfs will complain that it cannot find any GBM, and indeed, I compile it to use those drivers, any idea how can I fix that?

                                    Do you have X server running (Raspbian GUI) when you launch the example? If so, don't. Start the app directly from command line, without the X server. Not sure if it will help, but maybe.

                                    I have not encountered that error myself.

                                      @sierdzio I'm running it without X server, as I should

                                      Now, I'm curious about this, what libs are you using for glesv2 and egl?, I'm using the ones in /opt/vc/lib folder, and I also cross compiled the Qt with those

                                        @ronpetit said in Qt on Raspberry pi3:

                                        Oh I don't remember to be honest. I think I didn't change anything from stock settings. I also didn't specify the OpenGL libs manually anywhere when building Qt or apps.
