I have created a sample hello world!! program for 2.6 kernel and named the file as hello.c. i compiled it with Gcc as $gcc -c hello.c to get hello.o then i tried isnerting the module as $insmod hello.o it gives me some error messages saying that the module created is of invalid type. can i just do a normal compilation or do i need to create a makefile and add some additional information into it.
