Hi,

I have a problem writing my first module for linux. I use ubuntu 6.10. The module code starts with:

#define MODULE
#include <linux/module.h>

unfortunately in /usr/include/linux there is no such file...

Ok I say, still i have /usr/src/linux-headers-2.6.17-11/include/linux which holds all headers that are in /usr/include/linux/ and more (including module.h)

So I linked /usr/src/linux-headers-2.6.17-11/include/linux directory to /user/local/incude/linux (ln -s).

but...

Whan I compile I get about 100 errors being in these hearers... seems I'm doing something totally wrong way.

Thanks for feedback

Ok, I figured it out myself.
The thing is, on from kernel 2.6 (if i'm right?) compiling with kernel headres linked directlty does not work (some problems with dependecies/pathes ?)

shat you should do is create Makefile similiar to :

obj-m := modtest.o
KDIR := /lib/modules/2.6.17-11-generic/build -> this is where headers are
PWD := $(shell pwd) -> or just directory where the make file is
default:
$(MAKE) -C $(KDIR) SUBDIRS=$(PWD) modules

hope it helps anyone
