hello
I want to make kernel module dummy.ko using multiple
.c and .h files. In short i am telling .c and .h files
with directory structure
1> dummy.ko should made be using module1.ko and
module2.o (i.e
module2.o uses module1.ko to make dummy.ko)
2> module1.ko made using a1/a1.c & a2/a2.c and both
.c file
use /home/include/a.h
3> module2.o should made using b/b1.c which use
use /home/module2/include/b.h
Suggest me tht should make i make module2.o or
module2.ko and then combine it with module1.o to make
dummy.ko
/home/------
|_ include _
| |
| a.h
|
|___module1_
| |__ a1 ____
| | |
| | a1.c
| |
|__ a2 ____

Looking forward for ur reply
thanks in advance

You cannot make a module with a module as input.
It does not make sense.
Either you create a module or you don't.
So you will create following modules:
module1.ko + module2.ko
Alternatively you create one module but using the individual .o files as
input which is more likely what you want - correct?
Then your Kbuild file would look like this:
Kbuild:
obj-m := dummy.o
dummy-y := module1/a1/a1.o
dummy-y += module1/a2/a2.o
dummy-y += module2/b1/b1.o
# Tell where to find .h files
EXTRA_CFLAGS := -I$(src)/include
And to compile your module:
make -C $PATH_TO_KERNEL_SRC M=`pwd`
I assume you already read Documentation/kbuild/modules.txt - otherwise
please do so too.
Please include the source or provide an URL to the src if you need more
help.

hi,
Anil just put the names of your .c files where I have mentioned. Hope
this will work

MDIR = drivers/misc

PWD = $(shell pwd)
DEST = /lib/modules/$(CURRENT)/kernel/$(MDIR)
obj-m := $(TARGET).o
$(TARGET)-objs := [Names of your .c files with .o extension] [for
example file1.o file2.o ETC]

Your Makefile try to stay compatible with 2.4 + 2.6.
And this includes a lot of extra stuff that can be removed for 2.6.
So only if the users wants to be compatible with both 2.4 AND 2.6 this
template is usefull.

Hi Sam
Thanks fop your help ..but my problem is not solved it
...i putting my real problem here below.
1>my fist need is to make module1.ko made using
a1/a1.c , a1/a11.c & a2/a2.c a2/a22.c and all .c file
use /home/include/a.h
2>Now my 2nd need is to make module2.ko using
module1.ko and b/b1.c & b/b11.c (these both .c files
use /home/include/a.h and /home/module2/include/b.h)
In short my directory structure is as:
/home/------
|_ include _
| |
| a.h
|
|___module1_
| |__ a1 ____________
| | | |
| | a1.c a11.c
| |
|__ a2 ___________
| | | |
| | a2.c a22.c
|
|___ moudule2_
| |
| |__include _
| | |
| | b.h
| |___b1________
| | |
| b1.c b11.c
Looking forward for ur reply
thanks in advance

This was covered in my first response.

This does not make sense. You cannot link in one module
into anohter. And you would not be able to use module1
with module2 loaded due to name clash.
But you can certainly call one module from another module.
You just have to make sure module1 is loaded before module2.
Last time I requested an URL to the source IIRC?
