Whatz the error that you get?

Do you have the source of your running kernel, itz required for building your module.

[winifred_mit]

I don think i have the source....wer do i find themm.....

[cyberinstru]

You can get it from www.kernel.org

Configure, compile, and have a running kernel.

Then compile your module.

You can get it from www.kernel.org

Configure, compile, and have a running kernel.

Then compile your module.

Don't forget backup you're running kernel first....
Or don't override the running kernel.... while compiling the new kernel

[winifred_mit]

But how do i take a back up... and then re-compile a new kernel !!!!
Gimme the steps yaar....
Thanx for helping...

You will need to do some research yourself, Google is your friend.
There are a lot of tutorials detailing how to write a simple module that prints "Hello world" in dmesg out there

hi winifred,
I am at the same situation where ur standing, when ur including the driver what is the makefile u wrote for it.
look at my make:
************************************************** ***************************
obj-m += hello.ko

all:
make -C /lib/modules/2.6.x.x/build M=$(PWD) modules
************************************************** ***************************
it has to look into /usr/src for that source 2.6kernel that is not happening for me it is saying no rule in makefile
pls give me ur makefile
****cyberinstructer please help buddy***

[cyberinstru]

Try this.

MYKERNEL=`uname -r`

ifneq ($(KERNELRELEASE),)
# call from kernel build system

obj-m   := hello.o

else
 
KERNELDIR ?= /lib/modules/$(MYKERNEL)/build
PWD       := $(shell pwd)

default:
        $(MAKE) -C $(KERNELDIR) M=$(PWD) modules

endif

clean:
        rm -rf *.o *~ core .depend .*.cmd *.ko *.mod.c .tmp_versions

depend .depend dep:
        $(CC) $(CFLAGS) -M *.c > .depend


ifeq (.depend,$(wildcard .depend))
include .depend
endif

i am using ur makefile only cyberinstructer but one more pbm

build link in my /lib/modules is looking for this source ,( it is a broken link)
usr/src/kernels/2.6.15-1.2054_FC5-i686
i included a wrong source i guess it is showing error as ...(kernel-2.6.15-1.2054_FC5.src is what i included)
[root@localhost hello]# make -f Makefile.txt
make -C /lib/modules/`uname -r`/build M=/home/rajasekhar/hello modules
make: *** /lib/modules/2.6.15-1.2054_FC5/build: No such file or directory. Stop.
make: *** [default] Error 2

if so please send me the correct i686 source ,i search on kernel.org but i think i am a bad searcher
