Building modules: missing scripts/basic/Makefile

Building modules: missing scripts/basic/Makefile

[Steven Laabs]

Hi,

I'm trying to build my first kernel module but when running the makefile, make tries to use a file at /usr/src/linux-headers-3.16.0-4-common/scripts/basic/Makefile which gives me the "No such file or directory" error. I've looked into the folder it is referencing and it  does not have any Makefile, the only file in that location is the fixdep executable. The scripts folder itself is linked to ../../lib/linux-kbuild-3.16/scripts.

The Makefile I am using (located in a folder in my home directory):

obj-m = hello.o
KDIR ?= /lib/modules/$(shell uname -r)/build

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

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

I'm not quite sure where to look for this Makefile as I believe I have all of the proper headers installed, and I am running everything with the proper permission level.

Any ideas on what I may be missing here?

Thanks,
Steven

You should use "+=" and not "="
-- obj-m = hello.o
++ obj-m += hello.o

Thanks for pointing that out, I've made that correction. Still missing the Makefile as previously mentioned unfortunately so I am unable to build.

Hi Steven, please verify the headers are correctly installed by running:
dpkg -s linux-headers-$(uname -r) .

If they are not properly installed please run:
apt-get install kernel-headers-$(uname -r)

You should be able to build :)

Good luck - Aruna

Hi Aruna,

I ran dpkg -s linux-headers-$(uname -r) and the status indicated it was all installed ok. Just to be sure I reinstalled it as well as the dependencies (linux-headers-3.16.0-4-common and linux-kbuild-3.16). Reinstalling them seems to have not made any difference as my Makefile is still looking for a Makefile that does not seem to exist (which ultimately should be located in /usr/src/linux-kbuild-3.16/scripts/basic/).

Hi Steven,
Could you please post the output of make when you run it please ? And
what does ls -alh /lib/modules show you ? And what does ls -alh
/usr/src show you ?
