I recompiled libpcap to use shared libraries and now have the following
in /usr/lib:
lrwxrwxrwx 1 root root 16 Jan 23 08:56 /usr/lib/libpcap-0.8.3.so ->
libpcap-0.9.3.so
-rwxr-xr-x 1 root root 375850 Jan 23 09:00 /usr/lib/libpcap-0.9.3.so
-rw-r--r-- 1 root root 483168 Jan 23 09:00 /usr/lib/libpcap.a
-rwxr-xr-x 1 root root 792 Jan 23 09:00 /usr/lib/libpcap.la
lrwxrwxrwx 1 root root 16 Jan 23 09:00 /usr/lib/libpcap.so ->
libpcap-0.9.3.so
lrwxrwxrwx 1 root root 16 Jan 23 09:02 /usr/lib/libpcap.so.0 ->
libpcap-0.9.3.so
lrwxrwxrwx 1 root root 16 Jan 23 09:03 /usr/lib/libpcap.so.0.8 ->
libpcap-0.9.3.so
lrwxrwxrwx 1 root root 16 Jan 23 09:03 /usr/lib/libpcap.so.0.8.3 ->
libpcap-0.9.3.so
I added the symlinks for libpcap 0.8.3 with hopes that it would help,
but it didn't.
I have run ldconfig since reinstalling libpcap.
Attempting to recompile snort and tcpdump both end with the result of:
checking for strerror... yes
checking for __FUNCTION__... yes
checking for floor in -lm... yes
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
This makes me think that I'm missing something accosiated with libpcap.
Any more ideas?
Thanks in advance.

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]

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.
