Makefile with flags

[amitbern]

Hi,
Small question regarding makefiles:
I want to add a new target: release
that will compile my driver with additional flag
(EXTRA_CFLAGS += -Drelease_flag)

how can i do that on this example:


KERNELPATH := /home/kernel-2.6.24/

.PHONY: all clean
EXTRA_CFLAGS += -Werror
EXTRA_CFLAGS += -I$(src)/dir1
EXTRA_CFLAGS += -I$(src)/dir2

all: modules
obj-m := driver.o
driver-objs := file1.o
driver-objs += file2.o

modules:
make -C $(KERNELPATH) M=$(PWD) modules

clean:
make -C $(KERNELPATH) M=$(PWD) clean

thanks

Can't you do something like this:

release:
make -C $(KERNELPATH) M=$(PWD) -Drelease_flag modules

What error does it gives?
First of all make sure whether that "make" (after release) is valid.
You can put "echo" statements inside release, so that you can debug the make file..
