a. You need to use more than 'gcc -c module.c' to build a module
for Linux 2.6.x. See current linux/Documentation/kbuild/*.txt .
b. You load a module file named "mymodule.ko" for Linux 2.6.x,
not "mymodule.o".
c. Make sure that you are using current module-init-tools package.

Hi,
I'm new to Linux module dev, I copied a very simple module from a book
(http://lwn.net/Kernel/LDD2/ch02.lwn) and I can't insert it into the
kernel.
I found hundreds of bug reports about it on google without any solution.
I must be doing something wrong...
/*----------mymodule.c-----------*/
#define MODULE
#include <linux/module.h>
int init_module(void)
{ printk("<1>Hello, world\n"); return 0; }
void cleanup_module(void)
{ printk("<1>Goodbye cruel world\n"); }
/*----------EOF-----------*/
# gcc -c mymodule.c
# insmod mymodule.o
insmod: error inserting 'mymodule.o': -1 Invalid module format
Thanks a lot

Looks like 3.1.

I should have also said:
I don't think that's your current problem.

Just an FYI, but that book relates to the 2.4 version of the kernel.
The next version deals with 2.6, and I think the author hinted it would
be available around February.
