Re: Calling Comedi functions in RTLinux

Hi, again!

I checked my modules and it seems, that I have all required files inserted:

Module                  Size  Used by  
kcomedilib              4320   0  (unused)
fl512                   1408   0  (unused)
comedi                 25824   0  [kcomedilib fl512]
rtl_sched              50276   0 
rtl_fifo               10144   0 
rtl_posixio             7008   0  [rtl_fifo]
rtl_time               11144   0  [rtl_sched rtl_posixio]
rtl                    27392   0  [kcomedilib comedi rtl_sched rtl_fifo rtl_po
sixio rtl_time]
mbuff                   5228   0  (unused)

Then I took a look at the examples Dave mentioned. Those files have the 
follwoing includes:

<linux/comedi.h>
<linux/comedilib.h>

So I should be able to find these files in /usr/include/linux - but they are 
not there. Does that mean that something went wrong during installation? I 
searched my PC and found four files: comedi.h and comedilib.h in /usr/include 
(those most be the userspace files, correct?) and comedi.h and comedilib.h in 
/usr/src/comedi-0.7.66/include/linux. Those shold be the real-time files?

Anyway I included:

include "/usr/src/comedi-0.7.66/include/linux"

in my rtlinux module and changed the line 

include <linux/comedi.h> 

in /usr/src/comedi-0.7.66/include/linux/comedilib.h to

include "comedi.h"

I compiled again and it worked. But when I wanted to insert the module - i 
got a kernel panic.

Any further suggestions?

Thanks very much :)
