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 module just with typing

modprobe cdemu

no message should be given by this command

for you Debian users (maybe others), you might have to run `update-modules` first

#*#*#*#*#*#
#*# 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/rules.d/99cdemu:
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.
