Did you install the kernel source or at least the kernel headers?

 Hi Gustavo

I tried your suggestions.

The first line didn't work because I seem to not have a build directory
there.
And the second one did exactly the same as mine did.

 Maybe you should replace the KERNEL_DIR definition in MAKEFILE. My
suggestions:

 KERNEL_DIR:=/usr/src/linux-headers-$(shell uname -r)/build
 or
KERNEL_DIR:=/lib/modules/$(shell uname -r)/build
