Subject: Dependant modules question
Date: Fri, 02 Jul 2004 16:36:53 +0400	[thread overview]
Message-ID: <40E556E5.90708@vlnb.net> (raw)

Hello,

I need some assistance with the kernel build system. It looks like this 
topic is not covered anywhere, at least I didn't find anything.

I have two modules, A and B, where B is dependant from A, i.e. uses some 
exported from it symbols. Both modules are built outside of the kernel 
tree.

With A everything is fine, it's compiled and installed with other kernel 
modules in /lib/modules/2.6.7/extra.

Then module B is built. Here I have a problem. Module A is not listed as 
the module from which B depends in .mod.c file, therefore there are 
"Undefined symbols" warnings and it is impossible to load B, even though 
A is loaded.

So, the question is: what should I do to make A be seen as exporting 
some symbols by the kernel and its build system?

The kernel is 2.4.7, EXPORT_SYMBOL() used in A as required.

Thanks,
Vlad
