The Comedi source code all looks VERY old -- nothing dated newer than 2005 there, which (unfortunately) is an eternity for Linux kernel code. It is simply too outdated to build on modern kernels.

If you were to try *last year's* version of Kubuntu, then it would probably build/run without problems on that (5.04 "Hoary", or possibly even 5.10 "Breezy").

But until they update their source code, it won't build on a modern kernel, regardless of the distribution you use. Note that Redhat generally uses very outdated kernels, so it might work there (but not on Fedora).

EDIT: Their CVS version has some timestamps from 2006, so perhaps try building that instead of the .deb version.

Cheers
