Hi,
I'm almost finished with the beta of a new driver, but the final part is
giving me a headache.
I created my own Makefile, and as long as I compile with that Makefile,
everything goes fine (except insmodding, but perhaps this goes better when I
build the module together with the rest of the v4l-tree).
First, my system specs:
It's an AMD Athlon XP 2500+ with Ubuntu 7.10 and standard kernel of Ubuntu
(version 2.6.22-14).
The makefile I created looks something like this:
obj-m += dvb-driver.o
dvb-driver-objs := driver.o otherfile.o another.o
EXTRA_CFLAGS := -I/usr/src/linux-source-2.6.22/drivers/ieee1394
EXTRA_CFLAGS += -I/usr/src/linux-source-2.6.22/drivers/media/dvb/dvb-core
EXTRA_CFLAGS += -I/usr/src/linux-headers-$(shell uname -r)
EXTRA_CFLAGS += -I/usr/src/linux-headers-$(shell uname -r)/include
all:
make -C /lib/modules/$(shell uname -r)/build M=$(PWD)
modules
clean:
make -C /lib/modules/$(shell uname -r)/build M=$(PWD) clean
Compilation using this file goes fine.
So, I modified this file as is stated in README.patches and created
something like this:
obj-$(CONFIG_DVB_DRIVER) := dvb-driver.o
dvb-driver-objs := driver.o otherfile.o another.o
EXTRA_CFLAGS := -I/usr/src/linux-source-2.6.22/drivers/ieee1394
EXTRA_CFLAGS += -Idrivers/media/dvb/dvb-core
driver.c: driver.h otherfile.h another.h
otherfile.c: otherfile.h driver.h
another.c: another.h otherfile.h
I added all the source-files to the directory dvb-driver in the folder
linux/drivers/media/dvb off the v4l-dvb-tree.
Then, I modified linux/drivers/media/dvb/Makefile so it contains the folder
of my driver. Finally, I added "source
"drivers/media/dvb/dvb-driver/Kconfig" to linux/drvers/media/dvb/Kconfig.
Now, when I try to build the complete library, there's no dvb-driver.o (or
any other off the .o-files) created. Some source-files are copied to the
v4l-directory, but no object is created.
Can anyone help me out with this? Because I'm rather stuck for the moment L
Greetings,
Ben
