[oe] Problems building a kernelmodule for OE

[Henk Geraads]

Hi,

I am not sure if i posted it in the correct mailing list!
But I am trying to make a kernel module for the OE distro angstrom 2007-12 for machine CM-X270.

when I try to make the module, following error message is produced!

My source for the module cfi-kernel is located in the
path: /home/henk/cm270/fifodrv

I create with "bitbake linux -c defshell -f" an enviroment with the
"correct" path's and env.var's.

Makefile:
	# Makefile for external CFI kernel module
	CFLAGS = -march=armv5t -Wall -D_GNU_SOURCE 

	ifneq ($(KERNELRELEASE),)
	# we are inside the kernel tree and called from kernel build system

	obj-m   := cfi-mod.o
	else
	# we are a separate module and start the kernel make and give it our directory
	KERNELDIR = /home/henk/oe/build/tmp/angstrom/work/cm-x270-angstrom-linux-gnueabi/linux-2.6.23-r8/linux-2.6.23

	#KERNELDIR = ../linux-26
	PWD       := $(shell pwd)

	default:
		$(MAKE) -C $(KERNELDIR) M=$(PWD) modules
	endif

	clean::
		$(RM) -rf *.o .depend .*.cmd *.ko *.mod.c .tmp_versions *~

	.PHONY: clean

	depend .depend dep:
		$(CC) $(CFLAGS) -M *.c > .depend

	ifeq (.depend,$(wildcard .depend))
	include .depend
	endif


start op the module sourcecode:

	#include <linux/module.h>
	#include <linux/kernel.h>
	#include <linux/ioport.h>
	#include <linux/fs.h>
	#include <asm/uaccess.h>
	#include <asm/io.h>

	MODULE_AUTHOR("Henk");  
	......


What is my mistake??

Thanks in advance for any reaction!
