[raj0825]

Hi all... I am new to kernel module programming. When i am trying to compile a kernel module by the below command

gcc -D __KERNEL__ -D__SMP__ -DMODULE -DMODVERSIONS -I /usr/src/kernels/2.6.35 -45.fc14.i686/include/linux/ -Wall -O2 -o mod1.o -c mod1.c

when i typed this i am getting the follwing error:

fatal error:linux/module.h: no such file or directory
compilation terminated

But the aforemetioned directory is there and the header file module.h in that directiory.

I didnt understand what you are talking about sir. I am very much new to linux and i never posted anything of this sort before. I am extremely sorry if anything wrong with my posting. Please consider my request and help me.

Try this:

gcc -D __KERNEL__ -D__SMP__ -DMODULE -DMODVERSIONS -I /usr/src/kernels/2.6.35-45.fc14.i686/include -Wall -O2 -o mod1.o -c mod1.c

The above is your build command with the "/linux" removed from the -I
I did that because the code is trying to include "linux/module.h" so your I statement should not have also had "/linux" at the end.

I'm also a bit suspicious about there being a space between the "-I" and the "/" before "usr"

Usually you should have no space after the -I like this:

-I/usr/src/kernels/2.6.35-45.fc14.i686/include

Thankyou Marko.. I removed /linux and i tried Still getting the same error..

What does uname -r say?

My point is that the kernel you're actually booted to should be 2.6.35-45.fc14.i686

Did you also take the space out from after the -I
?

Thank you

What about my uname -r question, are you actually booted to the same kernel that the include directory is pointing to?

In his original post, there seems to also be a space in "2.6.35 -45.fc14.i686" there should be no space between the .35 and -45
