    @sneubert

    Hi yes I installed these on the Pi in addition to the packages listed in
    https://github.com/Kukkimonsuta/rpi-buildqt
    RPi Install ninja on Rpi & resync
    Rpi Install ruby on Rpi & resync
    Rpi Installed Libxss
    Rpi Installed Ninja-build
    RPI installed gperf

    when I build per aktay's recommendation I get an error in qmake step:

    using python: /usr/bin/python version: 2.7.12
    Using extra options found in /home/syoung/raspi/src/qtwebengine/src/core/qmake_extras.gypi

    Using extra options found in /home/syoung/raspi/src/qtwebengine/src/core/qtwebengine_extras.gypi
    Updating projects from gyp files...
    gyp: name 'arm_thumb' is not defined while evaluating condition 'arm_thumb==1' in /home/syoung/raspi/src/qtwebengine/src/core/resources/resources.gyp
    gyp: name 'arm_thumb' is not defined while evaluating condition 'arm_thumb==1' in /home/syoung/raspi/src/qtwebengine/src/core/core_generated.gyp
    Project ERROR: -- running gyp_qtwebengine failed --
    

    FYI: This is the config summary from the qmake step from aktay:

    //Configure summary:
    
    Qt WebEngine:
      Proprietary Codecs ..................... no
      Spellchecker ........................... yes
      ALSA ................................... yes
      PulseAudio ............................. yes
    
    Qt is now configured for building. Just run 'make'.
    Once everything is built, Qt is installed.
    You should NOT run 'make install'.
    Note that this build cannot be deployed to other machines or devices``
    
    Thanks to everyone.

    Can you share the error and the operation you are doing?

        @sly110 said in How to build Qt for Raspberry Pi3:

        sudo git clone http://code.qt.io/qt/qtwebengine -b 5.8

        Are you sure git is installed? Try this, please.

          1st of all - thank you so much for your help!

          git is definitely installed on host but was not installed on Pi. Installed & sync with 2_sync.sh.

            @aktay

            FYI: using https://github.com/Kukkimonsuta/rpi-buildqt
            I have previously built:
            3.1, 3.2, 3.3. 34. AND svg, virtualkeyboard, serialport

            tried doing connectivity but it apparently depends on NFC that I did not see in the qt repo.

                I believe this is finally solved although it was an arduous process.

                • Started with fresh Ubuntu16 LTS and fresh Jessie Lite

                • Followed Aktays instructions to manually build qtwebengine. Each time it failed, tried to determine missing dependencies. This is what is needed on the VM in addition to those listed in Kukkimonsuta/rpi-buildqt : gperf, bison, flex, gcc-mulitlib, g++ mulitlib, libx32gcc-4.8-dev.

                Thanks to everyone who helped!

                  What did you do that actually solved the "gyp: name 'arm_thumb' is not defined" error?

                  Is this actually linked to missing dependencies on the host or target?

                  I've been trying to cross-compile Qt 5.8 for my RPi3 many different ways now, including the steps mentioned here, but I always end up with this error when it tries to compile qtwebengine.

                    I am also trying to crosscompile qt in raspberry pi 2 for the past weeks following the

                    https://www.ics.com/blog/configuring-qt-creator-raspberry-pi

                    https://wiki.qt.io/RaspberryPi2EGLFS

                    . I configured it without any errors. When i am running a console application the output is getting displayed on the raspberry pi but when i am trying to debug a widget application i am getting this displayed in my qt creator.

                    Unable to find dynamic linker breakpoint function.
                    GDB will be unable to debug shared library initializers
                    and track explicitly loaded dynamic code.Could not load shared library symbols for 22 libraries, e.g. /usr/lib/arm-linux-gnueabihf/libarmmem.so.
                    Use the "info sharedlibrary" command to see the complete listing.
                    Do you need "set solib-search-path" or "set sysroot"?Unable to query physical screen size, defaulting to 100 dpi.
                    To override, set QT_QPA_EGLFS_PHYSICAL_WIDTH and QT_QPA_EGLFS_PHYSICAL_HEIGHT (in millimeters).

                    can anyone help me in this?
                    thanks in advance

                      Hi amruz,

                      the build of your qt libraries is not in you sysroot. You can either copy qt5pi directory to <your sysroot>/usr/local/ on your development host or tell gdb to load the libraries from your target (see https://forum.qt.io/topic/76928/raspberry-pi-3-debug-info-how-to-fix/38)

                        @sneubert i tried by writing these commands in additional startup commands in qt
                        set sysroot target:/
                        but the same warning is coming..
                        when i am running a console app it is getting displayed in the raspberry without any problems.
                        but for widget application

                        Unable to query physical screen size, defaulting to 100 dpi.

                          ok, my answer was to solve the problem not beeing abel to debug your application:

                          Unable to find dynamic linker breakpoint function.
                          GDB will be unable to debug shared library initializers
                          and track explicitly loaded dynamic code.Could not load shared library symbols for 22 libraries, e.g. /usr/lib/arm-linux-gnueabihf/libarmmem.so.
                          Use the "info sharedlibrary" command to see the complete listing.
                          Do you need "set solib-search-path" or "set sysroot"? 
                          

                          for the remaining message:

                          Unable to query physical screen size, defaulting to 100 dpi.
                          To override, set QT_QPA_EGLFS_PHYSICAL_WIDTH and QT_QPA_EGLFS_PHYSICAL_HEIGHT (in millimeters).
                          

                          take a look at previous posts in this forum, e.g.
                          https://forum.qt.io/topic/77387/eglfs-unable-to-query-physical-screen-size-defaulting-to-100-dpi

                            Work around for arm_thumb error is to be found here
                            https://github.com/Kukkimonsuta/rpi-buildqt/pull/7

                            Following
                            https://github.com/Kukkimonsuta/rpi-buildqt/issues/8
                            I succeeded even in compiling 5.9 (arm_thumb work around was not necessary any more)

                            Both qtwebengine 5.8 and 5.9 work nicely and fast BUT mouse interaction does not work (only keyboard). Anybody had this experience? Very frustrating after all the trouble...
