makeing a loadable module

Greetings;

I found some code I can play with/hack/etc, in the form of a loadable
module and some testing driver programs, in 'dpci8255.tar.gz'.

Unforch its for a slightly different card than the one I have, and
once I've hacked the code to suit, I need to rebuild it.

So whats the gcc command line to make just a bare, loadable module for
say a 2.4.25 kernel? Obviously I'm missing something when it
complains and quits, claiming there is no 'main' defined, which I
don't think modules actually have one of those?

What I'm trying to do (hey, no big dummy jokes please :)

[root@coyote dist]# cc -o dpci8255.o dpci8255lib.c
/usr/lib/gcc-lib/i386-redhat-linux/3.3.3/../../../crt1.o(.text+0x18):
In function `_start':
: undefined reference to `main'
collect2: ld returned 1 exit status

The gcc manpage isn't that helpfull and I've now read thru it twice.
