Regarding building Kernel object in Linux 2.6


Hi,

I need to build a kernel object.

If I try with this command :

make M=/usr/src/linux2.6../../..

It is creating only ".o" files. I need a ".ko" to load it into the kernel.

How can I build a ".ko"?

Please help.

Thanks in advance.

Regards,
Jayaraghavendran.K

A basic Makefile for building kernel 2.6 modules looks like this

Assuming the source is in a file named foo.c

Code:
obj-m += foo.o

all:
	make -C /lib/modules/$(shell uname -r)/build M=$(PWD) modules

clean:
	make -C /lib/modules/$(shell uname -r)/build M=$(PWD) clean
HTH

Mad.

Hi,

Thanks for your reply!!

I want to recompile one of the drivers by changing their code.

Do I need to compile the entire kernel for doing this?
Is there a specific command only for rebuilding that module?

Thanks in advance!!
