Re: Snort 2.9.0.1 & OpenBSD 4.8 build problems

If you are having problems installing the DAQ on *BSD systems, please give
this patch a try.  It fixes some automake foo and removes an unsupported
automake sort.

To apply:

cd daq-0.4/
patch -p0 < daq-bsd.diff
make distclean
autoreconf

Then configure, make, make install as usual.  You should not need to
--disable-ipfw-module or --disable-static.

Let me know how it goes.

Thanks
Russ

FYI - Ross, your email address was bouncing yesterday (ross () riverstyx net).

Actually, that should have said try configuring with
--enable-dynamicplugin.

Also, can you send your DAQ config.log and output of make when you
don't disable ipfw?


Hi Russ,

I've tried adding --enable-dynamicplugin to my configure with the same
result.  Here's my current configure:

./configure \
--sysconfdir=/etc/snort \
--with-daq-includes=/usr/local/include \
--with-daq-libraries=/usr/local/lib \
--with-libpcap-includes=/usr/local/include \
--with-libpcap-libraries=/usr/local/lib \
--with-dnet-includes=/usr/local/include \
--with-dnet-libraries=/usr/local/lib \
--enable-perfprofiling \
--enable-ppm \
--enable-zlib \
--enable-dynamicplugin

I've attched the config.logs for both Snort and DAQ (without the
--disable-ipfw-module), and the make output for both.

Ross.

                How frustrating and embarrassing; I know that I tried
                this several times
                over the last few days as I'd seen it mentioned in one
                of the few
                threads I'd found with similar issues -- and I'd had
                no results from it.

                Anyway, this time (with --disable-ipfw-module used for
                DAQ 0.3) Snort
                was able to configure and build.

                That said, I'm now encountering this issue when trying
                to start Snort:

                FATAL ERROR: parser.c(5235) Could not stat dynamic
                module path
                "/usr/local/lib/snort_dynamicengine/libsf_engine.so":
                No such file or
                directory.


                Sure enough, that file doesn't exist (no so files are
                in either
                snort_dynamicengine or snort_dynamicprocessor) and I
                noticed this (or
                similar) several times during the make:

                ...
                /bin/sh ../../../libtool --tag=CC    --mode=link gcc
