    Default Trouble running application on ARM board

    Hi all,

    I am trying to port Qt-embedded-4.5.0 on to arm board.

    I have cross compiled Qt successfully without any errors.

    I copied libQtCore.so.4.5.0, libQtGui.so.4.5.0 , libQtNetwork.so.4.5.0 and the fonts on to the board maintaining the same directory structure as on host machine. I have renamed the libraries to:
    libQtCore.so.4, libQtGui.so.4, and libQtNetwork.so.4 respectively.

    When i run a sample "Hello world" application, the screen becomes blanks and no error is displayed on the console. It is the same with Qt examples.

    Please help.

    Thanks
    Vinay

    Hi All,

    I tested the framebuffer example from QT. It is able to draw 3 squares properly on the board.
    This confirms that the linux framebuffer is working.

    How do i test if QT is talking to linux framebuffer properly?
    Or do i need any libraries in between.



    Thanks
    Vinay

    See http://qt.nokia.com/doc/4.5/qt-embed...anagement.html
    Maybe you have to adjust that QWS_DISPLAY-var for your installation.
    It's nice to be important but it's more important to be nice.
