Have you got kernel include files????

/usr/src/linux-2.6.22.14/include
or
/usr/src/linux/include

You first need to install kernel headers matching the current running kernel to use for compiling. Then if you get more errors, post them again.

how to install that header file?please tell me i am new to linux

I don't know!
I know how to do it on my distributions, but there are tons of Linux distributions and many differ from one another. And I haven't got the time to sit here and tell you how to do it in every one of them.

In other words, tell us which distro you're using ;)

http://www.linuxquestions.org/linux/...Ask_a_Question
http://linuxsilo.net/docs/smart-questions_en.html
Please always tell, which "Linux" is used !
( Ubuntu, Fedora etc. etc. ) And version, please.

Missing package : 'linux-headers' or 'kernel-headers'
different names in different Linux's.
....

i am using UBUNTU 7.10 version....now currently i am running the kernel version number 2.6.22.14

Try "sudo apt-get install linux-source". Found after a very brief Google search, on the Ubuntu forums. And out of curiosity, why are you needing to compile the usbcore stuff again? Should already be part of your install....

sorry i am using version 2.6.20...No i removed that modules in make menuconfig...This is for the college project....

After changing the version...Now i am getting different errors and warnings...

No errors at all, just warnings,
almost normal.

With perfect code and a perfect compiler,
there might be no warnings.
....

but i didnt get .ko file.....nothing happened...i didnt get any module file after make this....

Generally about module build
http://www.captain.at/programming/kernel-2.6/
Makefile
And
http://www.linuxquestions.org/questi...5/#post3237765
see # 5, Compiling a module separately without
compiling entire kernel.

Suggest : put some of your text in code tags ... like the
above Makefile, makes it more readable, easier for you to get
