omnet++ - 我还需要做什么才能在 Omnet++ 中运行 lwIP 模拟？

问题描述

我仍在尝试在 Omnet 5.6.1（使用 INET 4.2.5）inet/examples/inet/nclients/omnetpp.ini 上运行以下模拟。当我在“项目功能”窗口中选中没有 TCP (lwIP) 复选框的情况下构建 INET 时，我得到了一个干净的构建。如果我选中复选框，我会收到以下 26 个错误：

When I try to run the simulation I get the following error:

我尝试重新安装 OMNET++ 并使用其他 INET 版本。我也尝试使用 OMNET 4.2.2，但没有成功。

有人可以建议我应该怎么做吗？

亲切的问候本杰明

解决方案

TCP_LWIP 功能仅适用于 Linux。在 Windows 上，某些函数与 windows winsock2 库发生冲突。（这就是默认禁用该功能的原因）
