Deploying QT Embedded 4.4.3 on the board

From a few blogs ago I successfully compiled QT/E 4.4.3. It installed in my virtual machine at /usr/local/Trolltech/QtEmbedded-4.4.3-arm/.
On the board use the following commands:

$ mkdir -p /usr/local/Trolltech
$ chown -R eclipse:eclipse /usr/local/Trolltech

In Xbuntu:

$ cd /usr/local/Trolltech
$ scp -r QtEmbedded-4.4.3-arm/ eclipse@192.168.0.50:/usr/local/Trolltech

“libstdc++.so.5” is required on the board. I obtained this from the precompiled binaries of QT3 on ftp.embeddedarm.com. Place this file in /usr/local/lib

On the board:
$ export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/linux-arm/lib/:/usr/local/lib:/usr/local/Trolltech/QtEmbedded-4.4.3-arm/lib/
$ export QWS_MOUSE_PROTO = Tslib

It is best to put these in /root/.bashrc so they get automatically entered for each user session.

Since QT/E writes to frame buffer it will mess the output of IceWM. I done a sudo apt-get remove icewm and removed x11 similarly. You can do it temporary by doing a ps -A and checking the process id of IceWM and doing a kill <psnumber>
To run the program, it requires a server program but if it is the server itself you use the -qws option. For example:
$ cd /usr/local/Trolltech/QtEmbedded-4.4.3-arm/examples/widgets/analogclock
$ ./analogclock -qws

Now the problem with the output is the colours are all messed up. It seems no green and red can be displayed. This took days and days to sort and this is all explain in my next blog.
