我正在与其他人专业制作的项目合作，所以代码应该没有错误。我遇到的问题很可能与项目配置有关。WinPCap设置给出“无法解析的外部符号”链接器错误
我正在编译的项目中，C和C++源文件保存在以下文件夹中，全部位于项目目录中：硬件，头文件，源文件，TCP/IP，uTasker和WinSim。当我尝试编译时，它返回以下生成日志：

LPC17XX.c保存在Hardware/LPC17XX文件夹中。
WinSim.c和WinSimMain.cpp保存在WinSim文件夹中。
我不知道如何配置我的链接器来解决这些问题，任何帮助将不胜感激。
编辑：我正在使用Visual Studio 2010来构建项目。
您需要链接到WinPcap库。在命令行中，您可以通过添加库名称（例如winpcap.lib）作为“link”命令的一部分来完成此操作。在Visual Studio中，您将不得不围绕项目配置对话框寻找链接器设置。 – simonc
