运行时错误：也许未链接其代码，或者未在Register_Class/ Define_Module/ Define_Channel中注册该类？

如何解决运行时错误：也许未链接其代码，或者未在Register_Class/ Define_Module/ Define_Channel中注册该类？

我已经声明了Define_Module（veins :: TraCIDatedissemination），并通过了各种建议，但再次收到此错误。任何建议都欢迎。请帮忙。

How to register a new class (new application) in Omnet++ Error in module during network setup: Class "simpleModule" not found in omnetpp https://doc.omnetpp.org/omnetpp/manual/

在手册中，我检查了-

7.12.3 Class Registration
You should also use the Register_Class() macro to register the new class. It is used by the createOne() factory function,which can create any object given the class name as a string. createOne() is used by the Envir library to implement omnetpp.ini options such as rng-class="..." or scheduler-class="...". (see Chapter [17])

但无法理解。请帮助。

A runtime error occurred:

Class "TraCIDatadissemination" not found -- perhaps its code was not linked in,or the class wasn't registered with Register_Class(),or in the case of modules and channels,with Define_Module()/Define_Channel() -- in module (omnetpp::cModule) RSUExampleScenario.node[0] (id=13),at t=1s,event #2

Launch a debugger with the following command?
