我正在與其他人專業製作的項目合作，所以代碼應該沒有錯誤。我遇到的問題很可能與項目配置有關。WinPCap設置給出「無法解析的外部符號」鏈接器錯誤
我正在編譯的項目中，C和C++源文件保存在以下文件夾中，全部位於項目目錄中：硬件，頭文件，源文件，TCP/IP，uTasker和WinSim。當我嘗試編譯時，它返回以下生成日誌：

LPC17XX.c保存在Hardware/LPC17XX文件夾中。
WinSim.c和WinSimMain.cpp保存在WinSim文件夾中。
我不知道如何配置我的鏈接器來解決這些問題，任何幫助將不勝感激。
編輯：我正在使用Visual Studio 2010來構建項目。
您需要鏈接到WinPcap庫。在命令行中，您可以通過添加庫名稱（例如winpcap.lib）作爲「link」命令的一部分來完成此操作。在Visual Studio中，您將不得不圍繞項目配置對話框尋找鏈接器設置。 – simonc
