Hi,
	I have written a system call which is used to return the current default gateway address. What I did is the following.

1. add a new system call table entry for the new system call.
2. define a system call number for that call.
3. define a macro for user to link with
4. copy my program to /usr/src/linux/net directory and change
the Makefile of that directory in order to compile my program.
5. re-compile the kernel

But I found that there is an error message which is...

"arch/i386/kernel/kernel.o(.data+0x304): undefined reference to `sys_forwarding_agent" causes the failure.

Would anyone tell me what is going on??

Thanks for your kind attention.

bye g.
