I've been through several more rounds with this problem now.  For
reasons I don't understand, I couldn't install a later version of flex.
At this point, I decided that I needed to try a different version of
Linux.  Having already failed in using Debian, I installed Fedora Core
5.  This version (along with CentOS when updated) failed because of a
change in library contents.  At that point I installed Fedora Core 4,
and found virtually the same problems cited in the earlier e-mail.  At
this point I felt I had nothing to lose by going back to CentOS again,
hence I'm pretty much back to the same point.

It appears that I can do the install directly up to the point of the
installation of the CVS version of comedilib.  With the earlier failure
in this step, I pulled down the tarball version of comedilib and
attempted that installation.  The subsequent "make" step is attached
below:

At this point it appears I could proceed further provided I had the
contents of the missing "asm-generic/errno.h" file.  I queried google,
but could not find precisely what I needed.  Could someone there provide
me with this file?
