Omnet and Inet linking error : undefined reference to typinfo

Question

我需要在 Omnet 上实施自定义协议，我需要从给定设备 D 了解所有邻居 。我认为 D 可能是来自 Inet 的 AodvRouter，因为它已经有一个路由表。我扩展了 AodvRouter（见下面的代码），但我一直有 undefined reference to 'typeinfo for inet::IIpv4RoutingTable'（如 here）
参考资料，我在Windows10，Omnet5.5.1，Inet4.1.1.

我试过：使用其他答案中提到的不同编译器，但没有用。如果有任何警告有帮助，我最近的结果是：

我想要一个解决方案来完成这项工作，或者任何其他获取邻居列表的建议。

我必须不同意重复标签引用：问题不在于错误类型（当然是链接），而是如何使其在 omnet 环境下工作。

Answer 1

这是 Windows 上的 CLANG 问题。要么：

使用最新版本的master
使用 v3.x 分支
通过将 configure.user 更改为 CC=gcc 和 PREFER_CLANG=no
