Hi all,
I have a source tree from which I want to build a module.
Obviously, in only one of these files I have the
module_init(...)/module_exit(...) stuff, along with the
MODULE_LICENCE("GPL"); macro.
This is a code excerpt:
#include <linux/kernel.h> /* We're doing kernel work */
#include <linux/init.h>
#include <linux/version.h> /* For KERNEL_VERSION macro */
#include <linux/module.h> /* Specifically, a module */
....
MODULE_LICENSE("GPL");
....
/*
* Initialize the module - Register the character device
*/
static int qres_init_module(void)
{
...
}
/*
* Cleanup - unregister the appropriate file from /proc
*/
static void qres_cleanup_module(void)
{
...
}
module_init(qres_init_module);
module_exit(qres_cleanup_module);
The make process goes well: the module will finally be created. The
problem arises when I try a modinfo on the module. This is the output:
filename: qres_mod.ko
vermagic: 2.6.15-gensched 386 gcc-3.3
depends:
srcversion: C25502BA9363CC7DA452088
Why is there no module licence specification?
Any help will be greatly appreciated. Thanks all!
Bye
Try testing if the qres_mod.ko module have in this .modinfo section the
license entry:
objdump -j .modinfo -s qres_mod.ko
On 2.6 kernel MODULE_LICENCE expands to __MODULE_INFO.. that is a null
macro if MODULE is undefine
Are you sure you have compiled the module correctly?
