libpcap needs to be declared as dependency

[tve]

After a successful ./configure:

# make
g++ -c -Wall -g -O2 -std=c++11 -DFUZZER_VERSION=0.1 -Iinclude main.cpp -o main.o
In file included from /usr/include/tins/tins.h:49:0,
                 from main.cpp:25:

 #include <pcap.h>
                  ^
compilation terminated.
make: *** [main.o] Error 1

After installing libpcap, the linking is failing due to missing -lpcap:

root@oc1:~/dot11decrypt# make
g++ main.o -lpthread -ltins  -o dot11decrypt
/usr/bin/ld: main.o: undefined reference to symbol 'pcap_breakloop'
//usr/lib/arm-linux-gnueabihf/libpcap.so.0.8: error adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit status
make: *** [dot11decrypt] Error 1
root@oc1:~/dot11decrypt# g++ main.o -lpthread -ltins -lpcap -o dot11decrypt

Which version of libtins are you using? That pcap_breakloop reference was removed a lot of time ago.

I updated and installed today on an ARM Ubuntu 14.04 system:

BTW, the program worked great for me, I'm just trying to provide feedback to make it easier to install for the next person. Basically on my Ubuntu 14.04 system I had to do:

apt-get install libtins-dev libtins1 libpcap-dev libpcap0.8
./configure
make
g++ main.o -lpthread -ltins -lpcap -o dot11decrypt

Okay, cool. That libtins version is really old, the current version is 3.2. You might want to install it, as there were several bug fixes in between.
