comedi and rtai 3.1

I'm surprised that it works for you and apparently also for other people.
I have kernel 2.4.26, use RTAI-3.1, and tried comedi and comedilib
with adeos support from cvs in order to get comedi_lxrt to work.
Everything compiled well, I have the comedi drivers for my card and all
the modules you mentioned. The problem is: the module rtai_comedi_lxrt
does not load. Modprobe (and also 'depmod -a') complain about unresolved

I know, I should check this in more detail, e.g. the origin of the
unresolved symbols, etc. However, for the present I gave it up when it
became clear that my DAQ application will not need LXRT. And I am now busy
writing a GUI frontend for my comedi application, which must be ready for use
within a few days. Maybe, I'll try to clarify the comedi_lxrt issue later.

best regards
