Hi Ross,
Could you disable ipfw in daq please?
If not work, please resend (snort) config.log.
Regards

Hi,

JJC: that worked however it looks like Snort's not
building /usr/local/lib/snort_dynamicengine/libsf_engine.so for some
reason now.

Nov  4 15:48:19 snort[17745]: FATAL ERROR: parser.c(5235) Could not stat
dynamic module path
"/usr/local/lib/snort_dynamicengine/libsf_engine.so": No such file or
directory.


Russ: You're right, the output looks much like you anticipated:

nm /usr/local/lib/libdaq_static.a | grep daq_load_modules
000008c0 T daq_load_modules

I've attached two config.log files, one generated when I try to include
the static daq libraries, and the other when I configure without them.

Definitely appreciate the help, I haven't had any problems in the past
and this one just has me banging my head against the wall.

 
OK, now try this:
 
sudo ldconfig -p | grep daq
 
Edit /etc/ld.so.conf and add a line with /usr/local/lib.  Then:
 
sudo ldconfig -v | grep daq


ldconfig's not quite the same on OpenBSD, but I can confirm that the directory containing daq (/usr/local/lib) is 
already in the hints for ldconfig:

ldconfig -rv | grep daq 
        search directories: 
/usr/lib:/usr/X11R6/lib:/usr/local/lib:/usr/local/lib/daq:/usr/local/lib/snort_dynamicengine:/usr/local/lib/snort_dynamicpreprocessor
        112:-ldaq.0.1 => /usr/local/lib/libdaq.so.0.1

Ross.
