LinuxQuestions.org - [SOLVED] Compiling Kernel Modules in Ubuntu 10.10

After Being Fully Enthusiastic and ready to make my own Kernel Modules I started the work to be done to get started into kernel programming...
I have managed to successfully compile my own kernel...But while compiling my modules
After trying continuously for about 4-5 hrs....... I am totally frustrated and Asking for your help!!!

System Information :-

Linux Version : Ubuntu 10.10 i386
Kernel Version : 2.6.32.26

The Problem :-

The main problem is the make part...
I have a hello-1.c code from http://www.faqs.org/docs/kernel/x204.html

Code:

/*  hello-1.c - The simplest kernel module.



 */



#include <linux/module.h>  /* Needed by all modules */



#include <linux/kernel.h>  /* Needed for KERN_ALERT */



int init_module(void)



{



  printk("<1>Hello world 1.\n");



        



  // A non 0 return means init_module failed; module can't be loaded.



  return 0;



}



void cleanup_module(void)



{



  printk(KERN_ALERT "Goodbye world 1.\n");



}

and a Makefile is from different source as the above source provides makefile for kernel 2.4

Code:

ifneq ($(KERNELRELEASE),)



# We were called by kbuild







obj-m += target.o







else  # We were called from command line







KDIR := /lib/modules/$(shell uname -r)/build



#KDIR := /home/cynove/src/kernel/linux-source-2.6.31



PWD  := $(shell pwd)







default:



        @echo '    Building target module 2.6 kernel.'



        @echo '    PLEASE IGNORE THE "Overriding SUBDIRS" WARNING'



        $(MAKE) -C $(KDIR) SUBDIRS=$(PWD) modules







install:



        ./do_install.sh *.ko







endif  # End kbuild check



######################### Version independent targets ##########################







clean:



        rm -f -r *.o *.ko .*cmd .tmp* core *.i

I am constantly getting the same errors :-

Code:

    Building target module 2.6 kernel.



    PLEASE IGNORE THE "Overriding SUBDIRS" WARNING



make -C /lib/modules/2.6.32.26+drm33.12-explict-hax0r/build SUBDIRS=/home/aneesh/semtex modules



make[1]: Entering directory `/home/aneesh/source/linux-source-2.6.32'



make[2]: *** No rule to make target `/home/aneesh/semtex/target.c', needed by `/home/aneesh/semtex/target.o'.  Stop.



make[1]: *** [_module_/home/aneesh/semtex] Error 2



make[1]: Leaving directory `/home/aneesh/source/linux-source-2.6.32'



make: *** [default] Error 2

I am totally discouraged and frustrated by not getting results after trying so hard...
I checked the Makefile and seems it all is right ….
Really I am unable to get a clue what's wrong...
I thing maybe something is missing... But what?Where?Why?

Thanks in Advance

Your's faithfully
