[SOLVED] debian - where is the build directory in /lib/modules?

Hi!

I just installed a debian box (running on qemu... don't have much installed as a matter of fact).

I'm trying to compile the sbull driver but I find there's no build directory inside /lib/mudules:

Code:

root@debian:~/sbull# make
make -C /lib/modules/3.2.0-4-686-pae/build M=/root/sbull modules
make: *** /lib/modules/3.2.0-4-686-pae/build: No such file or directory.  Stop.
make: *** [all] Error 2
root@debian:~/sbull# ls /lib/modules/3.2.0-4-686-pae/build
ls: cannot access /lib/modules/3.2.0-4-686-pae/build: No such file or directory

that makes sense... the directory is missing indeed so... where is it? I bet there's something I have to install (I already instaled linux-sources, just in case).

Thanks in advance.

perhaps the problem is my Makefile:

Code:

obj-m := sbull.o

PWD := $(shell pwd)
KDIR := /lib/modules/$(shell uname -r)/build

all:
        make -C $(KDIR) M=$(PWD) modules
clean:
        make -C $(KDIR) M=$(PWD) clean

Hi,

it should be in the linux-headers package that correponds to your kernel. Eg

Code:

apt-get install linux-headers-$(uname -r)

Dude, you are right... now I'm getting a ton of error messages from the compilation process. So glad. Thanks!
