sys_call_table

[ram]

I need to write a system call interception module for a machine
running redhat 8 using the 2.4.18-14 kernel.

when I compile my code I have no problem

but when I run insmod I get
unresolved symbol sys_call_table

I found sys_call_table in
/usr/src/kernel/ksyms.c:
declared as
extern void *sys_call_table;

doesnt this mean I should be able to use it?

I tried recompiling the kernel after adding the following to ksyms.c
EXPORT_SYMBOL(sys_call_table);
...but it does not work

Thanks
