| |
Hi people,
I am new to kernel module writing and I base myself on the Linux Device Drivers book from O'reilly. I have written this simple module :
#include <linux/module.h>
int init_module(void) { printk("<1>Module inserted\n"); return 0; }
void cleanup_module(void) { printk("<1>Module removed\n"); }
-------------------------------------------- And this is the Makefile :
KERNELDIR = /usr/src/linux
include $(KERNELDIR)/.config
CFLAGS = -D__KERNEL__ -DMODULE -I$(KERNELDIR)/include \ -O -Wall
ifdef CONFIG_SMP CFLAGS += -D__SMP__ -DSMP endif
all : moduletest.o
clean : rm -f *.o *~ core
---------------------------------------------
And look at this :
bash-2.05b# make gcc -D__KERNEL__ -DMODULE -I/usr/src/linux/include -O -Wall -c -o moduletest.o moduletest.c bash-2.05b# insmod ./moduletest.o insmod: error inserting './moduletest.o': -1 Invalid module format
Anyone know what needs to be added or changed for kernel 2.6, or maybe its simply my own mistake?
(By the way, if you know of a kernel-beginner mailing list that would be better suited about this, tell me)
Thanks a lot in advance,
Best regards,
