Compiling Kernel Modules Individually

I'm learning to write a network device driver. For this I'm trying to compile code from /usr/src/linux/drivers/net.

My query is how to compile driver code individually.. for eg. if I want to compile ethertap.c (present in the same directory) by using the gcc command, rather than using make modules. I copy the file, ethertap.c to my home directory /root & run,

Code:

gcc -c ethertap.c

but get a lot of errors.

Any help is appreciated.

OK, this sounds corny but got the solution myself. I just had to use the switches -D__KERNEL__ & -DMODULE. So I use -

Code:

gcc -D__KERNEL__ -DMODULE -c ethertap.c

and it works fine!
