Can't get snort to compile with snmp.

[Matthew Schumacher <matt.s () aptalaska net>]

All,

I am trying to compile snort using:

./configure --with-snmp


It compiles for a while and then dies with the following output:

gcc  -g -O2 -Wall -L/usr/local/lib  -L/usr/local/ssl/lib -o snort

I noticed that it is not playing nice with openssl so I compiled again 
with the command:

./configure --with-snmp --without-openssl

and I get:

I really would like to make this work for a project I am working on, so 
any help would be greatly appreciated.

BTW, here are the software versions I am running:

snort-1.8.1-RELEASE
ucd-snmp-4.2.1
openssl-engine-0.9.6b
linux-2.4.9
RedHat 7.1
Glibc-2.2.2

Thanks,

schu
