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. e-mail: eg_ckmac@stu.ust.hk |
