can't include headers

can't include headers

[gndutm]

hi,
I need to write a device driver under linux. I am using slackware linux  kernel 2.4.18. 
I have problem to include headers, here is some of my code:

#define __KERNEL__
#include <linux/config.h>      (ok) 

#ifdef CONFIG_MODVERSIONS
#define MODVERSIONS
#include <linux/modversions.h> (ok)
#endif

#include <linux/module.h>      (ok)
#include <linux/stddef.h>      (ok) 
#include <linux/kernel.h>      (ok)               
#include <linux/mm.h>          <--- can't include this one
 
Any comments is greatly appreciated.
Thanks alot.

Ganda

No, this is not OK. Add a simple Makefile like the normal kernel ones 
and do something like 
	make -C /lib/modules/`uname -r`/build SUBDIRS=`pwd`

It's the only way to get the correct gcc options &c.
