Hi,
I'm trying to get directfb and gtk going on an Atmel AT91SAM9263
buildroot and directfb-1.4.11/13. Some dfb examples work fine (df_neo,
df_palette), although the colours are off. Other examples (like
df_fire and df_particle) SIGSEG or SIGILL.
The demos start up fine with:
~~~~~~~~~~~~~~~~~~~~~~~~~~| DirectFB 1.4.13 |~~~~~~~~~~~~~~~~~~~~~~~~~~

then they fail for some reason.

The common denominator here seems to me to be the Cop_to_Aop_*

further?
Thanks
