I apologize for my lack of C programming / build chain knowledge, but
I'm unable to successfully use the built libpcap.so.1.6.2 library,
included in the pf_ring source, after commit:
d31def0bd55e125799ce294fb9cfd720d87cb37d
In case it matters, my use case for pf_ring is having it load balance
network traffic, across many snort instances. I'm running fully
updated RHEL 6.7, using an Intel 82599ES network card, and attempting
to configure pf_ring in zc mode. This setup has been working for the
last several months.
Here is the relevant snippet of the script I'm using to build pf_ring
and it's components.
cd $BUILD_ROOT_DIR/pf_ring
cd kernel
echo -e "\n\nStarting Build of pf_ring kernerl \n\n" >>$BUILD_LOG
make clean >>$BUILD_LOG
make >>$BUILD_LOG
sudo make install >>$BUILD_LOG
cd ../userland/lib
echo -e "\n\nStarting Build of pf_ring userland/lib \n\n">>$BUILD_LOG
./configure >>$BUILD_LOG
make clean >>$BUILD_LOG
make >>$BUILD_LOG
sudo make install >>$BUILD_LOG
cd ../libpcap
echo -e "\n\nStarting Build of pf_ring userland/libpcap \n\n">>$BUILD_LOG
./configure >>$BUILD_LOG
make clean >>$BUILD_LOG
make >>$BUILD_LOG
sudo make install >>$BUILD_LOG
The rest of the script builds the ixgbe zero copy driver, the snort
daq, the pf_ring daq zero copy module, and finally snort itself.

snort: snort: error while loading shared libraries:

Can anyone offer any help? I can provide build logs or additional
information if needed.
