How run C programe in Kernel

[bostan]

Hi I am trying to create the socket in kernal space and for that I have written server.c file.
I am trying to comiple this programe in kernel space by following the procedure of creating the Makefile and than running the make. My files are as follows and I am getting folwwoiung error.
Can somebody will help me on this please ?
-Thanks

Makefile

obj-m += server.o
#KVERSION = $(shell uname -r)
all:
make -C /lib/modules/$(shell uname -r)/build M=$(PWD) modules
clean:
make -C /lib/modules/$(shell uname -r)/build M=$(PWD) clean

when I run make I get following error

% make
make: Nothing to be done for `all'.

Is there a tab before the make command after the target all: ? If it is empty, or just spaces, it won't work. It has to be a tab. Also, when posting code, including make files, use the CODE directive - start with square-bracket+code+close-bracket contents of code square-bracket+/code+close-bracket - to do so. Ie,

obj-m += server.o
#KVERSION = $(shell uname -r)
all:
make -C /lib/modules/$(shell uname -r)/build M=$(PWD) modules
clean:
make -C /lib/modules/$(shell uname -r)/build M=$(PWD) clean
