Problems running the demos

Hello,

I just managed to install comedi, comedilib. Now I can load comedi and 
kcomedilib, my device driver daqboard2000 and after a while I even managed 
to comedi_config my device.
With 'cat /proc/comedi' I get

comedi version 0.7.66
format string: "%2d: %-20s %-20s %4d",i,driver_name,board_name,n_subdevices
 0: daqboard2000         ids2                    3
daqboard2000:
 daqboard2000
8255:
 8255

So I thought everything is okay, but sadly none of the demos are running, 
I always get a 'segmentation fault' when I try to start one. It's the same 
when I do 
- make clean
- make 

In the config file I activated the FPGA stuff for the card.
The (probably) interesting kernel output in the case of the segmentation 
fault is

Versions of my software:
gcc: 2.95.3
linux kernel: 2.4.20 
rtlinux: 3.2-pre2
comedi: 0.7.66
comedilib: 0.7.20

With the actual release there is again a bug with the fpga, as in release 
0.7.56, if I try to do comedi_config I get the error message 'driver not 
found' and a kernelmessage

kernel: comedi0: daqboard2000: ids2no FPGA initialization code, aborting
kernel: comedi0: daqboard2000: remove

I think I got the same problem in april 2001, the thread was 'problems 
with comedi_config and comedilib'. The bug was removed in release 57. May 
be this can help to remove bugs from the test release 67.


I would be very grateful if anyone has an idea how to solve this problem.

Bye, Sacha.
