(Compile) undefined symbol: InitializePreprocessor

["Jason Monroe" <monroe () arcsight com>]

Hi All,

I've tried to compile snort 2.6RC2 on Fedora Core 5 as well as RHEL 4 AS which are GCC 4.1.0 and 3.4.5-2 respectively. 
Both distros are producing the same result.

./configure --enable-dynamicplugin --prefix=/opt/snort/2.6  && make && make install 
Then with the paths modified in the snort.conf
[root@manager snort-2.6.0RC2]# grep '/opt/snort' /etc/snort/snort.conf
var RULE_PATH /opt/snort/rules
dynamicpreprocessor directory /opt/snort/2.6/lib/snort_dynamicengine/
dynamicengine /opt/snort/2.6/lib/snort_dynamicengine/libsf_engine.so


running snort with -c option
/opt/snort/2.6/bin/snort -c /etc/snort/snort.conf

I have RPMs pcre-4.5 and pcre-devel-4.5 installed on the system 

The only thing that I could find regarding symbol version was to make possibly make use of --disable-symvers which 
would be given to the configure script, however, I don't think that was the correct place. 

I have:
/opt/snort/2.6/lib/snort_dynamicpreprocessor
/opt/snort/2.6/lib/snort_dynamicengine
both in /etc/ld.so.conf and re-ran /sbin/ldconfig

Perhaps I'm missing something simple that one of you folks could be so kind as to point out.

Thanks in advance,

JC
