Hi all
       I want to compile a kernel module.The source code file ,written by
native skin, prepared to compile is named "kernel-test.c".The comment of
makefile is described as follows=A3=BA
       ifneq ($(KERNELRELEASE),)
obj-m :=3Dkernel-test.o
else
KSRC ?=3D/usr/src/xenomai/linux-2.6.31.8
PWD     :=3D$(shell pwd)
default:
$(MAKE) -C  $(KSRC)    M=3D$(PWD)        modules
endif
        I tried to compile kernel module.Then I got:
make -I/usr/xenomai/include/  ARCH=3Darm CROSS_COMPILE=3Darm-linux-
make -C  /usr/src/xenomai/linux-2.6.31.8

It seems that my problem is caused by  Xenomai head file directory.How to
solve my proble?Thank you.
