我开始在项目中使用VACaMobil。但是，我遇到了问题。 我不知道我是不是错了，但我明白TraCIScenarioManagerLaunchd （因此，蚂蚁，VACaMobil）动态地创建代表每个车辆的节点，即。即 汽车模块没有在网络文件中定义，但它在omnetpp.ini文件中声明， 参数＆＃34; .manager.moduleType＆＃34;和＆＃34; .manager.moduleName＆＃34;。就我而言，模块 type是基于inet / examples / VACaMobil / Cars的Car模块的自定义汽车模块 模块名称是＆＃34; coche＆＃34;。
这是omnetpp.ini文件：

问题是在omnetpp.ini中，OMNeT ++给出了以下警告 以＆＃34; .channelNumber＆＃34;，＆＃34; .wlan。＆＃34;，＆＃34; .coche＆＃34;和＆＃34开头的行; .routingProtocol＆＃34 ;: ＆＃34;警告：未使用的条目（与任何参数不匹配）与任何模块参数都不匹配。＆＃34; 显然，OMNeT ++抱怨因为模块TAdhocHost，其名称为＆＃34; coche＆＃34;， 在Cars.ned中没有定义，但是没有假设OMNeT ++自动识别出＆＃34; coche＆＃34; 是由VACaMobil创建的？我做错了什么？我将不胜感激任何帮助。
答案 0 :(得分：0)
在最简单的情况下（所有模块都是通过模拟文件中的相应语句创建的），IDE可以简单地解析所有.ned文件以了解存在哪些模块。
但是，Veins TraCIScenarioManager直接使用OMNeT ++ C ++ API在运行时创建其他模块。在运行模拟之前，OMNeT ++ IDE无法知道这种情况会发生。
如果不了解您的C ++代码的作用，它就无法知道.ini文件中的模块参数（不是在开始时，而是在模拟的后期）会引用一个将存在的模块。
可能有办法解决这个问题（在.ned文件中声明不应该自动创建模块，但可以假设它存在），但我不记得任何不是黑客攻击的文件。 / p>
