    Hi,
    yes i am using the same ones.

    The configure command looks as follows:

    ./configure -release -opensource -confirm-license -arch arm -xplatform linux-arm-gnueabi-g++ -no-icu -no-pch -prefix /usr/local/Trolltech/qt5 -skip qtwebkit-examples -skip qtwebkit

    I have adapted the qmake.conf of the linux-arm-gnueabi-g++ to fit my cross compile toolchain.

    Do you see any issue?

          How did you install Qt on your board ?

            I normally just move over the files of the given configure path /usr/local/Trolltech/qt5 to the target board into the same directory.

            I found out if I use dbus-uuidgen -ensure before calling the app it starts up without the DBUS warning but the icon warning is still there.

            Also I cannot configure qt to work with webkit (see different post).

            Regards

              Did you use your device root filesystem to cross-compile build Qt 5 ? If not, you have probably used a different set of library than the one that's being used on your board

                How can I use it?

                I have just used the above written configure command.

                  Add -sysroot /path/to/your/mounted/device/filesytem to your configure options

                    But if I now do a make -j 4 I get an ICU warning, but ICU is needed for webkit, which I also need.

                    EDIT:
                    I have updated the icu using the following Cross Tutorial
                    http://thebugfreeblog.blogspot.de/2013/05/cross-building-icu-for-applications-on.html

                    now I added the following to the configure :
                    -icu -I /opt/icuCrossFinal/include -L /opt/icuCrossFinal/lib

                    Now I got a bit further, I also needed a new linux-atomic version.

                    I keep you updated on webkit configure,

                      Now I got the qtbase and webkit compiled, but If i want to start the app via

                      ./app -qpa linuxfb:/dev/fb0 it says:

                      This application failed to start because it could not find or load the Qt platform plugin "xcb".

                      I checked the dependencies on my Ubuntu 11.04 and I found that Ubuntu is unalbe to locate :
                      Unable to locate package libxcb-icccm4
                      Unable to locate package libxcb-icccm4-dev

                      I then run the configure with -no-xcb and all worked well so far.

                      But now if I start the application :

                      ./app -qpa linuxfb:fb=/dev/fb0

                      The screen is not using the full framebuffer (no fullscreen) it seems it is only using 2/3 of it an the rest is cut off.
                      With qt4 all works as expected.

                      Any idea why this happens?

                      Is xcb required for a webkit usage on linuxfb?

                        The plugin might have problem to detect the screen size

                          Also it seems qt5 is a bit slower then qt4, but I thought it should be faster.

                            Did you try to give the screen size to the plugin ?

                              yep, but no influence it changes only to smaller sizes but not to the larger screen size like it should.
