How to compile a .o file to a Linux kernel module (.ko) file?

Question

1. I write some code. Such as a test.c . I plan to compile it to a test.o file, and supply a head file.
2. Then, I supply this .o file to another programmer, he is writing a Linux kernel module, eg a driver.ko .

My question is: can he include my .o file in his .ko? How to write the make file? Is there any special requirement when I compile my .o file? Thank you very much.
