Dear all,
in a project, I have to make use of multiple modules that depend on
each other. Building works as far as dependencies are concerned for
run-time, it specifying 'modprobe module_one' makes the required
modules load.
However, there is "cosmetic" issue that annoys me: when I reference a
symbol of another external module, an 'undefined' warning message is
returned. Why?
module_1
- resides in its own directory structure
- EXPORT_SYMBOL_GPL(a_required_function)
- defines in module_1.h
extern unsigned a_required_function(struct sk_buff *skb);
module_2 resides in its own directory structure
- resides in its own directory structure
- requires "a_required_function"
- includes "module_1.h"
Compiling does not result in any error/warning.
Linking module_1 does not result in any error/warning.
Linking module_2 returns the warning:
MODPOST
*** Warning: "a_required_function" [path_to/module_2.ko] undefined!
Loading module_2 makes module_1 being loaded automatically in a
correct way, I do not like the Warning: message.
How can I avoid it?
Thanks for any help!
wbr,
Lukas
