Hi,

I'm trying to compile 2 external kernel-modules and want to use, in my second module, some symbols exported by the first module. Unfortunately, it doesn't work, but I can't figure out why ?
Here is what I'm doing in details and the error (a little bit long but simple ):

For module mod1.ko, , composed by one c-file mod1.c, I use such Makefile:

This module exports two symbols:
=> this module compiles and works fine.

Now I want to build my second module in another directory, which use foo() and bar().
I'm using a Makefile, similar to the previous one, except that it is composed by several c-file Thus, I use:All files compile fine, but modpost claims that:
And of course, when I 'insmod mod2.ko', it does work and claim that:
even if mod1 is inserted.

But if I 'grep foo /proc/kallsyms', I see my symbol:
What am I missing ? How do I tell my driver, that these symbols have to be searched in module mod1 ?
(Note: I'm using kernel 2.6.27)

And the answer is in the Documention directory of the kernel source tree (I missed this one), in file .../Documentation/kbuild/modules.txt , section 7.2-7.3.
