I tried to compile a small external module for my amd_64 2.6.11 kernel.
The module code is:
--------------------------ZIP
#include <linux/init.h>
#include <linux/kernel.h>
#include <linux/module.h>
#include <linux/vermagic.h>
#include <linux/compiler.h>
MODULE_INFO(vermagic,VERMAGIC_STRING);
MODULE_AUTHOR("Sko");
MODULE_DESCRIPTION("NoP");
static int __init demo_init(void) {
printk("initializing..\n");
return 0;
}
static void __exit demo_exit(void) {
printk("goodbye!\n");
}
module_init(demo_init);
module_exit(demo_exit);
MODULE_LICENSE("GPL");
---------------------------------
and the Makefile I used:
obj-m := ex0.o
#ex0-y :=
KDIR := /lib/modules/$(shell uname -r)/build
PWD := $(shell pwd)
default:
$(MAKE) -C $(KDIR) SUBDIRS=$(PWD) modules
-----------------------------
I module compiles succesfully but when I try to insmod it I get the following
message at the console:
#insmod -f ./ex0.o
insmod: error inserting 'ex0.o': -1 Invalid module format
and at /var/log/messages the following:
kernel: No module found in object
I use module-init-tools 3.2.2
#modprobe -V
module-init-tools version 3.2.2
Could anyone tell me what am I doing wrong..
Thanks in advance! :)

The kernel module should be compiled using the build files of the running kernel...compiling with anything else (i mean the kernel) will cause to this kind of error. system.map should match with the running kernel...AFAIK
for e.g if you are using Fedora Core 4 then the build directory will be /lib/modules/2.6.XXXXX/build/
then the output file of module will be file.ko in 2.6 kernel...
insmod file.ko should work
try it ...bye.
