I tried to compile kdbus on opensuse 12.2 using kernel 3.4 and got the
following compile errors:

ralf at yyy:src/kdbus> make
make -C /lib/modules/3.4.67-1.gc5211a6-default/build M=/home/ralf/src/kdbus
make[1]: Entering directory

compilation terminated.

make[3]: *** [_module_/home/ralf/src/kdbus] Fehler 2

Is there a minimum kernel version requirement ?
