You need to build against the kernel headers not the C library headers.
For FC1 see the kernel-source package and for 2.6 see /lib/modules/...
which now contains the right header set and is a more standardised way
of doing it

hi,
i am working in Fedora .
Kernel =2.4.22-1.2115.nptl #1 Wed Oct 29 15:42:51 EST
2003 i686 i686 i386 GNU/Linux

my kernel module program is
#include<linux/kernel.h>
#include<linux/module.h>
#include<linux/mm.h>
                                                      
                        extern *current;
int init_module(void){
return 0;
}
void cleanup_module(void){
}
                                                      
                        
~
when i give 
# gcc -c -DMODULE -D__KERNEL__ currenttask.c
the following error is shown.
what should i do?.
how to compile the kernel module with some kernel
header files ?.

Use a kbuld makefile:
obj-m := myfile.o

and compile using:
make -C path/to/kernel/src SUBDIRS=`pwd` modules

Hello All,

I upgraded the Linux kernel version from 2.6.20 to 2.6.23 on eval
board mpc8313erdb. Then I wrote a simple hello_world kernel module for
testing but when I do make it gives following compilation error.
Whereas I did not had this problem with kernel 2.6.20 !!!

It says; 'include/asm/current.h:35: error: invalid register name for =91cur=
rent=92'

Following is complete error log

################################

Could anyone please let me know the way to proceed or a way to think
to resolve this issue ? ? ?

Kindly please acknowledge ... thank you.

Kind Regards,
Vijay Nikam

Your linux-stable is build right? If not try to build it first then compile your module.

This is your running /installed kernel not the one you are building it against.

Based on the error messages, I'd say you're trying to compile in 64-bit mode
with a compiler build to support only 32-bit, or similar.

Hi,

     I get the following error while compiling my very basic kernel 
Module (a hello world module)

*
//--------------------------------------------------------------------------------------------------------------*
make -C /home/arun/Dev/linux-stable M=/home/arun/Dev/practice/Kmodules

what could be the possible cause of this error?

on my system

*$uname -a*
