Exporting symbols between modules

Exporting symbols between modules

[Sergio Paracuellos]

Hi all,

I'm new in this list and I have some problems exporting symbols in a
module to see them in other module.

In the module I want to export the symbol I do:

tList list;
EXPORT_SYMBOL(list);

I compile it and install without any problem.

And in the module I want to use them I declare list with "extern"
prototype:

extern tList list;

When I compile the module It says me that list is undefined, and I don't
know what I am doing wrong.

Does anybody know what is happening? 

Maybe a makefile example would be appreciated... 

Thanks in advance.

Regards,

        Sergio

1. the kernel-mentors list [1] is a better place for such questions
2. please post an URL to the full source of your driver, without it
   debugging your problem is not possible
