求大牛帮我编译下面这段代码。编译的时候老是报错。。无语，求高手编译好共享下文件感谢
/*============================================================================
Coder: Paris-ye
Released on: 1/9/2003
Test on: redhat 9.0
Our Team:Www.Bugkidz.Org
Information:
This is a arp spoof sniffer.
W <--- workstation
B <--- Server or GateWay
M <--- Man in the middle (agent),self IP address
Make:
first you must install "pcap" and "libnet"
gcc -I/usr/local/include -L/usr/local/lib -o sniffer sniffer.c -lpcap -lnet
Usage:
./sniffer -I [Interface] -M [Self IP] -W [Workstation IP] -S [Server IP] -P [port]
