It's an IPC API. See http://www.directfb.org/documentation/fusion.pdf > Can I get along without it (make all > the fusion functions NOOPs)? No. You definitely need fusion to do something. Currently two fusion implementations are provided: proper fusion using the linux kernel module and fake fusion using pthread. The latter supports running only one DirectFB app at a time. > Second, my target system has a very simple video interface that supports > only plain EGA/VGA.

They only work with the linux fbdev system. Currently two systems are provided: fbdev and sdl. The software accel driver works with both systems. What you need is a system that works on your OS. -- Ville Syrj�l� [EMAIL PROTECTED] http://www.sci.fi/~syrjala/ -- Info: To unsubscribe send a mail to [EMAIL PROTECTED] with "unsubscribe directfb-users" as subject.
