I'm using Ubuntu 10.10 and the installed kernel for driver programming. In rubini's book it is mentioned to create a .o file from a .c file, but I'm not getting it. it uses obj-m := eg_drv1.o, but when I try and build the .c file I get this:

error: make: *** No targets. Stop.

I'm completely confused. First question I have is how do I convert a .c file to .o file and then to .ko file to use the module?

Here is a nice article about 'Compile Linux kernel modules' http://www.cyberciti.biz/tips/compiling-linux-kernel-module.html

Just go through it. It contains an example just give it a try.

Hope this helps

UPDATE: I have just tried and found that copy and paste is not working. I have to manually enter the contents of Makefile to work it out. Anyway it works fine. Just try and let us know the result.

The issue with copy/paste and Makefiles is that makefile rules lines must start with \t (tabs), when you use copy/paste from the web those tabs are pasted as spaces breaking the syntax. –  João Pinto Dec 1 '10 at 15:36
    
@João Pinto: Yes you are absolutely right. –  aneeshep Dec 2 '10 at 4:48
