problems installing comedi

[Stienen, A.H.A. (CTW)]

Hi Jesse,

(I moved the discussion to the RTAI mailinglist, instead of the Comedi 
one...)

I do have to say that I didn't use the CVS versions of Comedi and 
Comedilib, but versions 0.7.70 and 0.7.21 respectively, with RTAI 3.2. 
And I'm using a good old-fashioned 2.4.27 kernel, as I know this just 
works! :) I've build it on a Slackware 10.2 system, which comes with GCC 
3.3.6. Nevertheless, I didn't have to pass the 
--with-rtaidir=/usr/realtime for the configuration; without it, Comedi 
make just worked.

Perhaps somebody here knows why Comedi didn't build for you.

(You actually did check to see whether RTAI was installed to 
/usr/realtime before you compiled Comedi, right?)

Hope you succeed! But I will put the steps I used on a website sometime 
soon!

Kind regards,
Arno.
