The install is quite simple, so that currently there is no automatic install.

#*#*#*#*#*#
#*#  1  #*#
extract the archive, what you apparently already did ;-)

#*#*#*#*#*#
#*#  2  #*#
you need the source of your current running kernel.
/lib/modules/`uname -r`/build/include needs to point at it. if you're not sure if it points
to the righ kernel just type: ls -la /lib/modules/`uname -r`/build if its the correct kernel
source all is ok. ;-)

#*#*#*#*#*#
#*#  3  #*#
make

Depending on your config of the gcc, you get non or many warnings, but even if you get
some, only one is in the cdemu module. e.g. on a Suse 8.2 with the suse standard kernel source
extracted to /usr/src/linux/ (/lib/modules/`uname -r`/build/ points to that) it looks this way.

************************************************************

if you get an error message (not a warning) like

cdemu.c: In function `ce_transfer':
cdemu.c:***: too few arguments to function `do_generic_file_read'

you most likely have a new redhat kernel.

you just need to change one line in the module source

search for this 2 lines
      do_generic_file_read(vc->vc_backing_file, &position,
                &desc, vc_read_actor);

and add a ",0" to the second line
                &desc, vc_read_actor, 0);
  

and as root

#*#*#*#*#*#
#*#  4  #*#
make install

#*#*#*#*#*#
#*#  5  #*#
now we can load the kernel modul just with typing

modprobe cdemu

no message should be given by this command

#*#*#*#*#*#
#*#  6  #*#
after the install you just need to call cdemu to get the help screen of the userspace program

if you're using devfs, then nodes will show up in /dev/cdemu/ automagically.  if you're using
udev, you might want to add this to /etc/udev/udev.rules:
KERNEL="cdemu[0-9]*", NAME="cdemu/%n"
otherwise you'll get a bunch of nodes showing up in /dev/ instead of /dev/cdemu/

ps: Any bug reports, comments, feature requests wished.
