Re: HELP: Error at exploit.so: undefined symbol: __guard

[Rachmat Hidayat Al-Anshar <rachmat_hidayat_02 () yahoo com>]

Hi Matt !!

It's working, I'm trying to..

1. modification the make file
# vi +14 /etc/snort/so_rules/Makefile
    add the "-fno-stack-protector" (to the CFLAGS argument)

2. re-make the so_rules, 
3. testing it

there is no error message occurred!!!
hope this can make it functionally working (^^!) ...

Thanks a million
Cheers 
~Mat(^^)~

Not sure if this will fix it, but it's something to try.

In the make file that builds exploit.so try adding -fno-stack-protector
to the CFLAGS line.
