我试图在omnetpp的inetmanet框架中使用包含 的UDP模块编写应用程序。问题是我必须包含的文件不包含在链接阶段。在omnetpp中构建我自己的模块的问题
的错误是：

我真的不知道为什么他们得到包括在内，我的模块编译罚款，但在链接阶段我得到“未定义的参考”。
有什么想法？
除非在这里有一个omnetpp专家，这将需要一些来回。生成文件没有正确处理依赖关系，因此链接器不会链接UDP代码（或者至少不是“泛滥”需要的那部分代码）。您可以先找到包含例如'UDPControlInfo（）'，并确定它是否被编译到一个目标文件中，如果是，那么这个目标文件是否被链接到一个库中。 – Beta 2010-12-12 20:16:56
