Hi All,

Thanks for the suggestions. I need more help to make it work.
I have installed the linux kernal 2.4.24 with RTAI 3.0r2 compiled
and installed on a pentium 3 machine. They are working well. (I intend
to move the software to a PC104 P3 900mhz machine with compactflash
disk later.)

Try 1: CVS current comedi
	1) edit autogen.sh, removal -1.4 from aclocal and -1.7 from automake
I am using automake 1.6.3. I know that suggested version is 1.7. Where to
get it?
	2) ./autogen.sh here is the output:

[everett_at_localhost comedi]$ ./autogen.sh
configure.ac: installing `./install-sh'
configure.ac: installing `./mkinstalldirs'

No configure is produced. What should I do here?

Try 2: released comedi 0.7.67
	1) ./configure
	runs fine
	2) make

Any idea how to preceed from here?

You must be using a more recent cvs checkout than the 0.7.67 release
though?  0.7.67 didn't have the --with-rtaidir configure option.
