problems installing comedi

[Jesse Gohl]

Hi Arno,

Yep, I checked the installation of RTAI to /usr/realtime.  It does
indeed exist.  I've actually tried the 2.4.27 kernel awhile ago too
(although that was on an installation of Debian).  In that case I had
other problems that seemed to be related to the installation of RTAI
itself. I've tried many different combinations trying to find one that
all installs smoothly.  This combination of Centos with a 2.6.10 kernel
was the best so far (until I got to trying to install comedi of course,
which was why I was originally posting to the comedi list).  Hmmm... I'm
not exactly sure what to try next.  Maybe I'll try Slackware... Thanks a
bunch for your input.  I'll let you know if I ever succeed!  :)
