I am a newer and my makefile is :

ifneq ($(KERNELRELEASE),)
obj-m:=hello.o

else
KDIR:=/lib/modules/$(shell uname -r)
PWD:=$(shell pwd)

default:
$(MAKE) -C $(KDIR) SUBDIRS=$(PWD) hello
endif

When I type 'make' on the command line, it says:
make[1]: Entering directory `/lib/modules/2.6.12-10-386'
make[1]: *** No rule to make target `hello'. Stop.
make[1]: Leaving directory `/lib/modules/2.6.12-10-386'
make: *** [default] Error 2

"2.6.12-10-386" is my kernel version.I don't know why and any answer is appreciated.
