You just want a trivial Makefile ?

See Documentation/kbuild/makefiles.txt for more info.

Here is a working trivial example:

#################### begin ###################3
# usage:
# make -C /path/to/kernel/source M=/path/to/source/TARGET/ [modules]

obj-m := TARGET.o

clean-files := *.o *.ko *.mod.c
############# end #######################

M= implies modules, so modules is optional.
I usually use M=$PWD (after cd to TARGET dir).

Hi,

The O_TARGET is no longer valid in kernel 2.4, what is the replacement of
following module object in kernel 2.6?

O_TARGET := NewSerial.o

obj-y   := new_s_driver.o queue.o
obj-m   := $(O_TARGET)

Thank you.

Jim

.ko is what modules are in 2.6, are you using some old version of the 
module utilities?

Thanks Randy, that works. But now it generated a NewSerial.ko instead of
NewSerial.o in kernel 2.6, this caused a problem when I called the insmod,
the insmod added another .o as follows:

insmod NewSerial.ko
insmod: NewSerial.ko.o: no module by that name found

Is it possible for me to get a NewSerial.o, not a NewSerail.ko?

Thank you.

Nope, loadable modules in 2.6.x are *.ko files.
That's what insmod and modprobe expect.

Are using module-init-tools instead of modutils?
You should be.
