          @Asha We know from the beginning that the OS is Linux. Linux is an operating system supporting different technologies for graphics, like: X11, directfb, eglfs, ...
          These technologies is what is called "backends" in Qt.

            @jsulm Hi ,Thank you for you guide...

            I found which plugin is running on my board,
            That is eglfs only,

            with this link https://doc.qt.io/qt-5/embedded-linux.html

            for beagleboneboard my build directory is Qt5,

            I got the information in the folder below

            cd /home/beagle/Qt5/mkspecs/devices/linux-beagleboard-g++/qmake.conf

            in qmake.conf file

            QT_QPA_DEFAULT_PLATFORM = eglfs

            so now,how to proceed next?

            can i change the QT_QPA_DEFAULT_PLATFORM in that file ?

            or need to configure with eglfs only?

                      @jsulm

                      I have extracted qt source code,that can be mmoved in QT5 directory,

                      in QT5/qtbase/mkspecs/devices/linux-beagleboard-g++/qmake.conf file,

                      the line presene QT_QPA_DEFAULT_PLATFORM= eglfs...

                      so now i need to configure,

                      I need to mentioned eglfs in my configure line,so

                      ./configure -platform linux-g++ -release -device linux-beagleboard-g++ -sysroot /home/beagle/BB/sysroot -prefix /home/debian/Qt5ForBBB -hostprefix ~/Qt5ForBBB -device-option CROSS_COMPILE="path" -egl -eglfs -nomake tests -nomake examples -skip qtconnectivitty -recheck-all -v

                      this is correct?

                          Check the configure log to see what was missing (I'm quite sure that I already suggested that before).

                              Hi,

                              Do you have any of these libraries available on your sysroot ?
                              If not then install the corresponding development package for your target.

                                        I dont have the libegl packages,how to install those packages?

                                        As any other packages...
                                        On my Ubuntu machine it is:

                                        apt install libegl1-mesa-dev
                                        

                                        Please learn to search for needed packages by yourself:

                                        apt search libegl

                                          libegl.png

                                          sysroot also have those libraries ,here is the attachement

                                          libegl2.png
                                          so now what is problem? why it is not enabling....(may be the problem in specifying the path for those libraries in qmake.conf file?)...
