WinPCap 设置导致"unresolved external symbol"链接器错误

WinPCap setup giving "unresolved external symbol" linker errors

本文关键字：symbol 链接 错误 external unresolved 设置 WinPCap      更新时间：2023-10-16

我正在与一个由别人专业制作的项目合作，所以代码应该是无bug的。我遇到的问题很可能与项目配置有关。

我试图编译的项目有C和c++源文件保存在以下文件夹中，所有在项目目录内:硬件，头文件，源文件，TCP/IP, uTasker和WinSim。当我尝试编译时，它返回以下构建日志:

LPC17XX.c保存在Hardware/LPC17XX文件夹中。

WinSim.c和WinSimMain.cpp存放在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:我使用Visual Studio 2010来构建项目。

关于WinPCap的文档与我所能找到的有点过时，但是有一些非常重要的设置说明，特别是应该定义的预处理器宏，以便为良好的链接正确设置。

我能找到的最新的安装文档在这里。我希望他们能帮助你。
