Hello directfb-dev
Sorry for asking here too. I tried directfb-users with little responce(1)
I am a newbie regarding directfb.
I am working on a project, where we are changing linux kernel from 2.4.3 to 2.4.25
I the 'old' system, we were using SVGAlib, and have been quite happy for that.
As we wanted to be able to add some more'fun' to bootscreen, we decided to go for
Framebuffer-device and DirectFB in the new project.
What I have managed so far is:
Patch our 2.4.25 - kernel with the linux-2.4.23-24-i810fb-lite.diff.bz2 to add
framebuffer-support for I810 to our kernel.
A few tweeks had to be done, but it seems to work.
A few line in syslinux.cfg was added:
video=i810fb:xres=1024:yres=768:bpp=16:hsync1=30:hsync2=55:vsync1=50:vsync2=85:accel:mtrr
Booting our system now brings a small Geek in the upper left corner.
Issuing these commands turn off cursor and disables screen-blanking:
setterm -term linux -blank 0 >/dev/tty0
setterm -term linux -cursor off >/dev/tty0
Issuing fbset -i gives following output:
sh-2.05a# fbset -i
mode "1024x768-69"
# D: 74.873 MHz, H: 55.053 kHz, V: 68.903 Hz

I have then managed to get DirectFB-0.9.20/0.9.21 to build static library and with
i810-gfxdriver-support.
I installed it to /usr/local and it now contains DirectFB-commands in /usr/local/bin
and the rest in /usr/local/lib (drivers etc...):
direct.pc directfb-internal.pc directfb.pc fusion.pc
sh-2.05a# ls -R /usr/local/lib/

sh-2.05a#
I have included /usr/local/bin in PATH.>
Copied fb.modes to /etc and created a small directfbrc in /etc too:
system = fbdev
fbdev = /dev/fb0
Running dfbinfo yields following output:
sh-2.05a# dfbinfo
(*) DirectFB/Config: Parsing config file '/etc/directfbrc'.

(!) DirectFB/core/system: No system found!
(#) DirectFBError [DirectFBCreate() failed]: No (suitable) implementation found!
sh-2.05a#
I get the same message, when I call
DirectFBInit(NULL,NULL) ;
in my application.
My application is 'static'-linked to libdirectfb.a(no errors)
We are using ElinOS 3.0 as target-Linux(2.4.25) and only need single-app.
What am I missing ?????
Can I expressly tell DirectFB to use the I810-gfxdriver ????
Is it o.k. to only use I810-lite ????
best regards
