newbie's advanture for Installing comedi-0.7.68

Hi All,

I have been trying to install comedi-0.7.68 to RTAI-3.0r2 and linux 2.4.24
I am not sure I did it correctly. But I managered to compile and install
the comedi package on my P3 450Mhz machine.

1) compile and install linux 2.4.24 with legacy patch
That went fine.

2) compile RTAI-3.0r2
in the make menuconfig, I turned on comedi switch. That went fine with the
new kernel.
latancy test seems to be fine:
min -838, max 6973, average 350

3)Install comedi-0.7.68,
This one gave me most trouble:
I untar the comedi-0.7.68

./configure
....

checking RTAI directory /usr/src/rtai... ./configure: line 3741: -d: command
not found
configure: error: incorrect RTAI directory?

I changed the configure file on line 5541:
	from
         if -d ${RTAI_DIR}/rtai-core/include  ; then
      to
	  if [ -d ${RTAI_DIR}/rtai-core/include ] ; then

The .configure ran through fine

make failed, complaining no rtai_config.h
fix:
cd rtai-3.0r2/rtai-core/include
ln -s ../../rtai_config.h .

make then ran fine. :-D, with some warns about VERSION, PACKAGE_NAME etc
been redefined.

make install failed, due to no depmod,
edit Makefile and replace depmod by /sbin/depmod
then make install ran fine

Is this the right thing to do? How to test if my comedi is install
successfully? I did a /sbin/modprobe dt2801. Here is the output:
[root_at_localhost comedi]# /sbin/modprobe dt2801

/lib/modules/2.4.24-rthal5/comedi/comedi.o: insmod

I don't have the dt2801 hardware installed on my machine yet. Shall I put
the card in and try the same thing?

Any suggestions?
