But the Makefile is so simple and Not use "cc".
#
obj-m := task_01.o
CFLAGS_task_01.o := -DDEBUG
KDIR:=/lib/modules/`uname -r`/build
PWD:=$(shell pwd)
default:
echo $KDIR
$(MAKE) -C $(KDIR) M=$(PWD) modul
thank you.
But the Makefile is so simple and Not use "cc".
#
obj-m := task_01.o
KDIR:=/lib/modules/`uname -r`/build
PWD:=$(shell pwd)
default:
echo $KDIR
$(MAKE) -C $(KDIR) M=$(PWD) modules
#
So, how to add "CFLAGS"?

hi all:
I'm confused with pr_debug. My codes is:
###
#include
#include
static int __init init_page_dir(void)
{
pr_debug("Hello world\n");
return 0;
}
static void __exit exit_page_dir(void)
{
pr_debug("\nGoodbye now...\n\n");
}
