How to set config_modversion on/off.

I am asking this question because I got the following
error when I tried to insert a modeule which I wrote.

deogiri:/users/pg05/ranjithk/Desktop/prg# gcc -c 3.c
deogiri:/users/pg05/ranjithk/Desktop/prg# insmod
./3.o
insmod: error inserting './3.o': -1 Invalid module
format

Can any one help me?
Thanks.

Is this for a 2.6 kernel?
If so, you need to build a 3.ko file, using the 2.6 kbuild
infrastructure. See Documentation/kbuild/* for doc & examples.

Your error messages isn't a modversions error, but you can
easily enable or disable modversions using make <your_favorite>config.
It's listed under the "Loadable module support" menu.
