unresolved symbols due to missing iwlcore.ko

unresolved symbols due to missing iwlcore.ko

[Bringfried Stecklum]

I am having trouble installing iwlagn from the recent compat-wireless. My system 
is Ubuntu 8.10 running kernel 2.6.36-1. The reason is that iwlcore.ko does not 
get build and installed in the update modules folder which, of course, leads 
unresolved symbols. Here is a short log

So no iwlcore.ko at this stage.

This is after make install

stecklum@extragalactix:~/System/src/compat-wireless-2010-12-12$ find . -name 
iwlcore.ko -print
stecklum@extragalactix:~/System/src/compat-wireless-2010-12-12$

and consequently the module is not in the update module folder. Thus, upon 
modprobe iwlagn the original kernel module will be loaded which, of course, 
lacks the new symbols.

Turns out that the error is due to a fault of the configuration script. If I
_don't_ select the iwlwifi driver via driver_select and build all drivers
instead, iwlcore.ko will be build as well and properly installed.

It looks like there is a mismatch between usage CONFIG_IWLWIIFI and
CONFIG_COMPAT_IWLWIFI in select script and the Makefile. I'm not sure
what is the intention so of COMPAT so I cannot say were it should be
fixed.

Likely the grep'ing out is dropping one config option out of the
Makefile, fix that and you can fix the problem.
