I am using fedora 16,and i have downloaded some code for keyboard driver from net, but while compiling them i got following error:

i8k.c:22:26: fatal error: linux/module.h: No such file or directory
compilation terminated.

Probably not a PATH issue.

? Did you do # yum install kernel kernel-devel
.... and reboot ?

i did this too..but still same problem.(though i already had dat kernel version which gets installed after this command.now i have two copies of same dir.)

some of the file which are included are:

#include <linux/interrupt.h>
#include <linux/module.h>
#include <linux/kernel.h>
#include <linux/types.h>
#include <linux/miscdevice.h>
#include <linux/major.h>
#include <linux/ioport.h>
#include <linux/fcntl.h>
#include <linux/init.h>
#include <linux/poll.h>

linux/interrupt.h: No such file or directory
compilation terminated.

OK, which driver is it about ? ?

A file name, and a download link, please.

( 'make' / Makefile will usually use the "build" link pointing to
/usr/src/kernels/`uname -r`/, i.e. /lib/modules/`uname -r`/build ,
and easily find linux/files.h in /usr/src/kernels/`uname -r`/include/.
So unless it's a poor Makefile, things should work OK.)

its from github.(i am newbie to device driver.)
pls download the code from below link.

Thanks

Fedora 16 :
Make sure that you are booting into the new kernel-3.4.7-1.
Can be checked with the command : uname -r

Keyboard_driver :
1) git clone https://github.com/ronaflx/keyboard_driver.git
2) cd keyboard_driver/
3) make : And the kernel module 'kbd_drv.ko' is created OK.

Thanks its its compiling now (after downloading the code againg though with few warnings ), but now when i am tryng to insert it by "insmod ./kbd_drv.ko" command it gives some error.

"insmod: error inserting 'kbd_drv.ko': -1 Device or resource busy"

i am no where near to understand the problem with it.
Thanks

Cool friend.....
"insmod: error inserting 'kbd_drv.ko': -1 Device or resource busy"

indicates that the driver is already running as a part of kernel. check out with 'lsmod' command. I hope you'll find it

jayeshsharma52 · 08-09-2012, 02:12 AM

If it should be with the same name as "kbd_drv" then its not there in lsmod.i searched it in dmesg also but dint found it.

Device .. busy : The keyboard is using another kernel module.
You will have to disable that module ( modprobe -r <module> )
before you can use a different one.

Additionally, the keyboard uses an xorg.x11 module :
/usr/lib/xorg/modules/input/kbd_drv.so
