Building kernel with framebuffer support (was: Re: GCC for kernel compilation)
I know I'm getting off topic but I don't know a better place to ask and
this subject might be interesting of other developers as well.

I get lots of warning (i.e. variable fb isn't used in aty182 driver). I
don't get these warnings when I use CC=gcc-2.95. It's a little bit
difficult to trace warnings and errors during a kernel compilation. I'd
be good if warnings and error where duplicated into a log file.
I'm trying to build a kernel with framebuffer support for the Matrox
G400 card but I always get "open /dev/fb0: No such device" when I use
fbset. A week ago I added a new 123GB harddisk to my system, installed a
new Debian 3.0r1 and upgraded to the current Sarge. But since then I
can't use framebuffer anymore while with the old system I used it for
about 2 years. For building I use the same settings (make menuconfig) as
before, so it should work unless there are any hidden settings in
2.4.21.
The command:
ls -la /dev/fb0
crw--w---- 1 root video 29,0 Mar 14 2002 /dev/fb0
seems to be correct as much as I know. I've tried to config each setting
new, I also installed the kernel-image-2.4.21-3-k6 but nothing helps.
What can I do to fix this situation?
