    Thank you for the advice. I have followed this document MANY times and only once did I get 5.7 to compile for RPi2. But it does not have webView or virtual keyboard which I need. My goal is to follow the document using RPi3 and Qt5.8 everywhere BUT to date regardless of what I try it ALWAYS fails. Usually for different reasons. The latest is wont build webEngine. I have followed MANY other docs as well in which people were successful and my builds still fail.
    I will keep trying. Thank you.

    Did you follow the instructions below? I tried and it works for Qt 5.8.

      webView

      The problem with the web components is that compiling it takes a lot of memory that the Pi just don't have.

        Thank you! This is an amazing link.

        I still have problem building webView (as it needs web engine) which will not build

          You can try to recompile the module.

          sudo git clone http://code.qt.io/qt/qtwebengine -b 5.8
          cd qtwebengine
          sudo ~/raspi/build/qt5.8-host/bin/qmake -r // If I'm not mistaken, it is correct path.check it please.
          sudo make -r
          sudo make install -r
          

          Good luck.

            did you install gperf? It´s needed to build WebEngine.

              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

              Note that this build cannot be deployed to other machines or devices``
              
              Thanks to everyone.

                    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.
                    
                    Prior to reconfiguration, make sure you remove any leftovers from
                    the previous build.

                      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.

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

                        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.

                          sudo git submodule update --init

                            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

                                . 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.

                                Use the "info sharedlibrary" command to see the complete listing.

                                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.

                                    is coming.
                                    :(

                                      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...
