        Hi,

        I login via debian user0_1568102197808_server.png

        then enabled the root login /etc/ssh/sshd_config file0_1568102251280_root.png

        here is the running status0_1568102281150_running.png

        now I am able login as a root0_1568102312397_rootlogin (1).png

        So, I changed the directory /opt permissions here "chmod go+wx opt"

        after this all, restarted the system ,and open the qt and run the simple application, the result is0_1568102663828_result.png

        0_1568102687165_result1.png

        So now what is the problem...any idea about this...(Thankyou very much)...

          @asha You did not cross compile your app for your device.
          You can verify this by doing (in a terminal):

          file PATH_TO_YOUR_EXE
          

          and checking its output.

              @asha You open a terminal and type "file" followed by the path to the executable file you built and press enter...
              For more information see "man file".

                    @asha Why qmake?
                    It is about your app (beagle) which is created if you build your app.

                          @asha Your binary is for x86-64 as you can see. What is your device CPU? I guess ARM?

                              @asha Then you did NOT cross compiled your app.
                              Is your Kit for the device configured properly?
                              It has red exclamation mark.

                                  @asha You need cross compiled Qt. Qt you're currently using is compiled for x86 as error says. You can't use x86 binaries on ARM.

                                    It means I have to download the qt for arm,right..

                                    I have to uninstall this qt for x86.

                                    after installing arm qt ,have to configure everything once again..

                                    right.

                                      @asha I think you'll end up boring lots of people that can help you if you don't stop and try understanding what you need to do to have both the Qt libraries and any application built with Qt cross-compiled in a Linux host and deployed and running successfully on your Beagle board.

                                      I'd suggest kindly to read (again?) this guide as it shows step by step what you need to do, both in your Linux machine (referred as workstation) and in your BBB device.

                                      Please set aside some time to go through it, do the steps listed there and see if you can succeed... good luck!
