problem with modules

i have a question regarding the makefile posted by wgoosens. i've tried to compile a module with this makefile, but it seems to me that there is something missing in it, because when i try to run make, it says

<div class='quotetop'>quote

--- quote end ---

--- quote start ---

make -k all

make: nothing to be done for `all&#39;.

--- Quote End ---

Maybe it&#39;s very simple, but I don&#39;t know what to add. To my eyes, it seems that I should add the objects to be compiled, for example, but I don&#39;t exactly how to do it.

What am I missing?

Thank you

You should name your objects in the obj-m variable.

If your module is named module.c make sure you have

# If KERNELRELEASE is defined, we've been invoked from the#  kernel build system and can use its language.
ifneq ($(KERNELRELEASE),)
obj-m := module.o#  Otherwise we were called directly from the command#  line; invoke the kernel build system.
else
KERNELDIR = /usr/src/cross/linux-2.6.11
PWD := $(shell pwd)
default:
$(MAKE) -C $(KERNELDIR) M=$(PWD) modules
endif

Is see that in the Makefile I posted I listed hello.ko and it should be .o NOT .ko

Next execute make as you would when compiling the kernel:

ARCH=nios2nommu CROSS_COMPILE=nios2-linux-uclibc- make

I hope these two steps will help you!
