Compiler cannot link to libpcap.so.1

Hi, all,

I just start using BeagleBone Black with TI linux sdk(linux-am335x-evm-03.01.00.06). I've installed sdk on Ubuntu 14.04 and added Wilink8 patch to it(followed instructions from TI, built and examined). libpcap.so.1 and libpcap.so.1.7.4 are in the sdk.

Now I want to develop on it with CCS. However I met some problem when I tried to use pcap in my code. I include an header "pcap.h" in my code but gcc cannot find it. I've tried some methods I could do with it, i.e.link libpcap(checked in /home/beagle/ti-processor-sdk-linux-am335x-evm-03.01.00.06/sdk3-wilink-filesystem-e14/usr/lib/libpcap.so.1) to compiler(absolute/relative path) in Makefile,   build project under environment_setup. I use "ldconfig -p" to check packages I have, another older version libpcap is in cache.  

Code is pretty simple. I'm sure this is the problem.

#include <pcap.h>
