I have tried the DirectFB-1.2.0-rc1, and now the DirectFB can work
correctly.So I re-cross compiled the GTK-DirectFB and its dependencies,
and the GTK widget could display on my screen , but the fonts and the
colors of the widget was incorrect.The fonts looked strange and the
color of widget was always pink.
I think it is the problem of fonts and color settings(rgb settings error
?),how can I resolve this problem ?
Thanks for your help sincerely.
To Brian Rhodes:
Is the package davincifb_2.6.10.tar.bz2 ? I dowloaded it but there
was no document or readme file to explain how to use it.
