Re: Error building 'Hello,World' kernel Module

[Shine Mohamed Jabbar <shinemohamed_j@naturesoft.net>]

Hi,

I tried ur program in my machine and
its working fine.

Apart from what u've done I did two more things
1) Copied the config file from the /boot to kernel
   source directory and done "make menuconfig"

2) Done a make in the kernel source till it compiles
   the first c file (CC      init/main.o). (I've done
   because to make a link of include/asm->include/asm-i386).

Regards,
Shine Mohamed Jabbar
