Trouble running application on ARM board

[evinay]

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-embedded-displaymanagement.html
Maybe you have to adjust that QWS_DISPLAY-var for your installation.
