    Hi,

    You don't give enough information. What version of Qt are you running on your board ? Which distribution is loaded ? etc.



  • I use Qt Creator 2.8.0 and Angstrom Distribution.., sir Sam,


  • Lifetime Qt Champion

    What message are you getting on the console when running your application ?



  • This is the error message from my executable file that I ran in terminal...

    root@beaglebone:/home/sqs/Documents# ./Keypad
    QWSSocket::connectToLocalFile could not connect:: No such file or directory
    QWSSocket::connectToLocalFile could not connect:: No such file or directory
    QWSSocket::connectToLocalFile could not connect:: No such file or directory

    QWSSocket::connectToLocalFile could not connect:: No such file or directory
    QWSSocket::connectToLocalFile could not connect:: No such file or directory
    No Qt for Embedded Linux server appears to be running.
    If you want to run this program as a server, add the "-qws" command-line option.
    root@beaglebone:/home/sqs/Documents#

    after that I ran it again with "-qws" but no output appeared.

    No error message with -qws ?



  • Yes, but no output.. sir..



  • There's an instance to run the application alone..


  • Lifetime Qt Champion

    I don't understand that last phrase



  • ah.. I mean, the executable file can run in the beaglebone without using X11VNC viewer..

    What plugin are you using ?
