Kbuild problem when trying to build module with make: cannot find Kbuild.include

Hi,

I am trying to build a simply helloworld module into the kernel.

I have a file called helloworldk.c with init and exit functions to be invoked with insmod and rmmod.

My kernel source tree is in /usr/src/linux-3.12.7

I created a Makefile with the line

Code:

obj-m :=helloworldk.o

and am executing the command

Code:

make -C /usr/src/linux-3.12.7 M='pwd' modules

However, I get the following output

Code:

make: Entering directory `/usr/src/linux-3.12.7'
Makefile:323: /usr/src/linux-3.12.7/scripts/Kbuild.include: No such file or directory
Makefile:579: /usr/src/linux-3.12.7/arch/x86/Makefile: No such file or directory
/bin/bash: /usr/src/linux-3.12.7/scripts/gcc-goto.sh: No such file or directory
make: *** No rule to make target `/usr/src/linux-3.12.7/arch/x86/Makefile'.  Stop.
make: Leaving directory `/usr/src/linux-3.12.7'

What am I doing wrong?

What are you exactly trying to compile? Did you put your code in the kernel source or is it separate? Is your kernel source configured (have you run make menuconfig or a similar command inside)?

I was trying to build it as an external module. I had to point the make -C command/argument to /lib/modules/kernel-name/build and I was just pointing it to the download location where I had downloaded the code. I finally did get it to work. I used fakeroot and make-kpkg to build the kernel and later inserted the module.
