GTK+ on the QBoxHD

The latest updates of the QBoxHD filesystem contain the GTK+ libraries compiled for DirectFB.
In order to test them, there are 3 games (gtktetris, sliders and calcoo) that you can run following these instructions:

$ killall -9 launcher enigma2
$ gtk-games <game>

where <game> is one of the dirs in /usr/local/games

For launching again enigma2:

$ /etc/init.d/launcher

Note that the libraries provided in the QBoxHD filesystem are not sufficient for compiling another GTK+ application, nor for recompiling GTK+ itself.
For cross-compiling GTK+ over DirectFB you can follow the official site: GTK on DirectFB for Embedded Systems that is not updated, or a newer but experimental site.
