This means you have forgotten to compile and install all your
applications and libraries.
It means you are mixing 1.2 and 1.3 programs, this can work but is
discouraged, and gives you this error message.

Hi Niels
Thanks for your response.
I thought the default was system=fbdev.
Now I have the DFBARGS set to sytem=fbdev with DirectFB-1.3 and when I
run arm-dfbinfo (or any other test DFB application) I see this error.
(!) Fusion/Init: World ABI (44) doesn't match own (45)!
Any idea why? (I am runnning fusion module 8.1.1)
However I tried the DirectFB-1.2 and I brought up two different
applications and it runs just fine. So, I will just
stick to 1.2 version for now and revisit DirectFB 1.3 later.
