[Xenomai-help] Symbols undefined [Scanned]

[Niklaus Burren]

Hello

Im trying to create a Xenomai kernel module for a ARM processor 
(PXA-270). In this module I register a interrupt handler with the 
function rt_inter_create(). When I compile the module I get the 
following warnings:

*** Warning: "rt_intr_delete" 
[/home/student/work/xenomai/latency-test/latency-test.ko] undefined!
*** Warning: "rt_intr_create" 
[/home/student/work/xenomai/latency-test/latency-test.ko] undefined!
*** Warning: "rt_intr_enable" 
[/home/student/work/xenomai/latency-test/latency-test.ko] undefined!

I don't know what is wrong. In my makefile I have defined the paths to 
the libraries and the include files of xenomai:

obj-m = latency-test.o

XENODIR = /opt/carme/rootfs/usr/xenomai
KDIR	= /opt/carme/linux-2.6.15-col2
PWD	= $(shell pwd)

EXTRA_CFLAGS = -I $(XENODIR)/include -L $(XENODIR)/lib

all:
	$(MAKE) -C $(KDIR) M=$(PWD) modules

clean:
	$(MAKE) -C $(KDIR) M=$(PWD) clean


Has someone an idea what is wrong?

Kind Regards

Have you enabled support for interrupts in the native skin? Check for 
CONFIG_XENO_OPT_NATIVE_INTR in your config file.
