You can:
- grep kallsyms_lookup from /proc/kallsyms (it is there on SL 5.5 and SL 6.0. You can edit your program and assign something like:
int (*my_kallsyms_lookup_name)(const char *name) = (void *) KALLSYMS;
where KALLSYMS is address found above, or your loading script can feed this address. if your kernel is compiled with kprobe, you can use it to get address too.
