此程序运行时还有1.o: In function `main':
/root/capture/capture/1.c:55: undefined reference to `pcap_lookupdev'
/root/capture/capture/1.c:62: undefined reference to `pcap_lookupnet'
/root/capture/capture/1.c:73: undefined reference to `pcap_compile'
/root/capture/capture/1.c:85: undefined reference to `pcap_loop'
collect2: ld returned 1 exit status
的错误,不知怎么调试.

可是我在kdevelop下要运用libpcap,怎么连啊?也就是编译时出现"1.c:17:18: pcap.h: No such file or directory "的问题.请问怎么解决!

用Gtk+也行，在gnome下直接用C调用Gtk+2.0函数库

现成的Ethereal已经做得很好了,为什么要重复劳动呢?

东西总是人开发出来的，重要的是不要做比人已经做的很好、很完善的东西，做东西要有点创新性
