Hi Mitja:
 
I think your problem is that you haven't used the standard Linux kernel
configuration tools to configure TIPC as a module.
 
If you look in tipc_dbg.c you'll see that the definition for TIPC_LOG is
prefaced by the following:
 
#if defined(CONFIG_TIPC_CONFIG_SERVICE) \
    || defined(CONFIG_TIPC_SYSTEM_MSGS) \
    || defined(CONFIG_TIPC_DEBUG)
 
These CONFIG_xxx symbols should be part of your Linux kernel
configuration file.  If you haven't used "make menuconfig" (or something
similar) to configure your kernel, then these symbols won't be defined
when you try building TIPC and you'll get the "undefined symbol" error
you reported.
 
So I suggest you try the following:
 
1) cd /usr/src/linux-header-2.6.20-16-generic/
2) make menuconfig
    - follow Networking -> Networking options -> The TIPC Protocol
    - hit "M" to configure TIPC as a module
    - save your kernel configuration
3) make net/tipc/tipc.ko
4) insmod net/tipc/tipc/ko
 
Note: I'm not familiar with building in the Ubuntu environment, so your
mileage may vary ...
 
Regards,
Al

kernelmodule
        Importance: High
        
        

        Hi Guys,

         

        I have a problem to run TIPC loadable kernel module. I'm using
Ubuntu Linux, kernel 2.6.20-16-Generic.

        My steps when trying to make TIPC working are next:

         

        -          Copy all files to
/usr/src/linux-header-2.6.20-16-generic/

        -          Go to
/usr/src/linux-header-2.6.20-16-generic/net/tipc/

        -          Execute: make -C
/usr/src/linux-header-2.6.20-16-generic/ M=`pwd`

        -          output of command above: make:
