Re: Qt Running Error

You are using beagle board without a network.  The error is a Qt library trying to find a socket.  I suppose you can 
start io-pkt-v4 without a driver, and the library will be happy.  You'll have to try it.

Re: Qt Running Error

Qt 4.8.2 does not default the plugin path as expected. Edit /bin/qTstat on the SD card and add the following as the 
first line so plugin for .jpg images can be used:

export QT_PLUGIN_PATH=/usr/lib/qt4/plugins

Re: Qt Running Error

Just export the variable  .. fo get qTstat

# export QT_PLUGIN_PATH=/usr/lib/qt4/plugins

before you run your program... or put it in a startup script.

Re: Qt Running Error

Hi Dennis,

You said this code export QT_PLUGIN_PATH=/usr/lib/qt4/plugins but I think this command only QT_PLUGIN_PATH=/usr/lib/qt4/
plugins not export QT_PLUGIN_PATH=/usr/lib/qt4/plugins for variable

You can look youtube link

Re: Qt Running Error

So why didn't you use the command I gave you - before running ./helloapp -qws

export QT_PLUGIN_PATH=/usr/lib/qt4/plugins
./helloapp -qws

Did you put the plugins in /usr/lib/qt4/plugins ?

Re: Qt Running Error

So did you include the font files?  There are about 80 of them in the 4.8 release.  My beagle image has them at /usr/
local/Trolltech/QtEmbedded-4.8.0-arm/lib/fonts.
