Greg,
Here is the directory structure.
test-module
|
+-- test1
| |
| +--test1.c
| +--Makefile
|
+-- test2
| |
| +---test2.c
| +---Makefile
|
+-- system
|
+ Makefile
The toplevel makefile is "test-module/system/Makefile", and this will
try to invoke "test1/Makefile", and "test2/Makefile", and build a single
module.
#system/Makefile :
#------------------
KERNEL_SRC_DIR = /usr/src/linux-2.6
obj-m := ../test1/
obj-m += ../test2/
all :
make -C $(KERNEL_SRC_DIR) M='pwd' modules
#test1/Makefile :
#----------------
obj-m += test1.o
#test2/Makefile :
#-----------------
obj-m += test2.o
This could build test1.ko, and test2.ko separately, but not into a
single module. I tried the following in system/Makefile, and this works.
obj-m := complete.o
complete-objs := ../test1/test1.o ../test2/test2.o
Then complete.ko is built properly, and I could install it successfully.
But I want something like this.
----------------------------
#build a single module from .o files in the "obj" directory.
obj-m := complete.o
complete-objs := ../obj/test1.o ../obj/test2.o
#Build all needed object files recursively in to a single "obj"
directory
obj-m += ../test1/
obj-m += ../test2/
----------------------------
Thanks
Suren
