Darryl -

Tried with no luck.  Still get the same error.

./configure --with-libpcap-library=/usr/local/lib

Thanks for the assistance.

Sorry bout that. Needed a little more sleep. It should be
- --with-libpcap-library=[your path]

Try ./configure --with-libpcap=/usr/local when compiling snort. If it
still fails then the library was probably compiled statically. If that
is the case, post back and I will tell you how to make it a shared
object. I think I had this problem a few years ago.

Subject: [Snort-users] Phil Wood Libpcap Installation Problems

I'm trying to get Phil Wood's modified libpcap working on my Snort 
2.6.1 sensor, but have run into some difficulties and hoping that 
someone out there can help.

I've downloaded and extracted libpcap-0.9.20060417.tar.gz.  I then
run:

   ./configure
   make
   make install

I then downloaded and extracted snort-2.6.1.1.tar.gz.  I then run:

   ./configure
   make

That's where it blows up.  Here is the error:

<snip>

checking for pcap_datalink in -lpcap... no

   ERROR!  Libpcap library/headers not found, go get it from
   http://www.tcpdump.org
   or use the --with-libpcap-* options, if you have it installed
   in unusual place

</snip>

Any ideas why the headers would be missing?  Header files are 
identified with the .h extension correct?  Where are these supposed to

reside on the system?

I'm running CentOS 4 with 2.6.9-42.0.3.EL kernel.

Thanks in advance.
