INVALID MODULE FORMAT

also is there any command to convert the *.C or *.h files into the *.o files ..

i think i got to get "this" *.o file by compiling …

Yes, you probably will have to Compile, but not just the module, the whole kernel. It is a long, involved, critical process. The first thing to do is find a site for your particular Linux distribution, since they all use slightly different tools to do this. Next, search out a few articles or a good how-to on recompiling the kernel with module support. Then double check everything, *BACK UP EVERYTHING IMPORTANT* and do the procedure step by step verbatim. Once you are familiar with it, you can relax a bit, but *NEVER WORK ON CRITICAL SYSTEM SOFTWARE* without *BACKING EVERYTHING UP!* I hope this helps you out, excuse the emphasis, but I don’t want the blame for not saying what may go wrong should it bomb out on you. If at first you don’t succeed, you’re about average. (Better than average, the kernel worked after the third time;)
