    Hi,

    opt directory has the permissions

    drwxr_xr_x,

    I changed the permissions through the command

    "chmod go+w opt"

    after this the permission of opt is
    drwxrwxrwx

    So,now again I build the application and getting the same problem.

    Any suggestions.

    @asha You changed the permissions on your target device?
    Also, this is a bad solution.
    Better give the user write access.

                @asha "how to install qt creator on ubuntu 18.04" - either install one delivered with Ubuntu using apt-get, or download QtCreator from official website.
                "which version qt is required" - you should know that. Which version do you want to use, or which version is supported by your SDK?
                "which version cross-compiler is required" - the one provided by the SDK for your device.
                "how to install that one" - should be part of the SDK.
                "how to install debugger also" - should be part of the SDK.

                    @asha said in cannot run: no command:

                    trying to login ssh root@192.168.7.2 there also same error permission denied..

                    So, you actually can't login using SSH?
                    Then you first need to solve this problem.
                    Looks like root is not allowed to login via SSH on this device.
                    Do you have other users there?
                    Also, see https://www.cyberciti.biz/faq/howto-limit-what-users-can-log-onto-system-via-ssh/

                        @asha Then either use that user or enable root login via SSH

                          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.
