Do you have the source of your running kernel, itz required for building your module. __________________ --------------------------------- Registered Linux User #440311 Forget what the World thinks...

Then compile your module. __________________ --------------------------------- Registered Linux User #440311 Forget what the World thinks...

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

There are a lot of tutorials detailing how to write a simple module that prints "Hello world" in dmesg out there __________________ Put your hand in an oven for a minute and it will be like an hour, sit beside a beautiful woman for an hour and it will be like a minute, that is relativity. --Albert Einstein Linux User #425940 Don't PM me with questions, instead post in the forums

Try this.

Code:

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
