Question

我想从Oment ++中inet的UdpBasicApp派生一个类。确实，我想编写自己的应用程序。我编写了以下代码，但是在编译项目时出现错误。要正确编译该项目，该怎么办？

Creating executable: out/clang-release//Manet_1.1.exe
out/clang-release//MyApp.o:(.rdata[_ZTIN4inet11UdpBasicAppE]+0x10): undefined reference to `typeinfo for inet::ApplicationBase'
out/clang-release//MyApp.o:(.rdata[_ZTV5MyApp]+0x640): undefined reference to `non-virtual thunk to inet::OperationalBase::handleOperationStage(inet::LifecycleOperation*, int, inet::IDoneCallback*)'
clang++.exe: error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [Makefile:101: out/clang-release//Manet_1.1.exe] Error 1

MyApp.h

#include "../../inet/src/inet/applications/udpapp/UdpBasicApp.h"

using namespace inet;

class  MyApp : public UdpBasicApp
{
public:
};

MyApp.c

#include "MyApp.h"

Define_Module(MyApp);

MyApp.net

import inet.applications.udpapp.UdpBasicApp;

simple MyApp extends UdpBasicApp
{
    @class(MyApp);
}

很显然，您正在自己的项目中工作，该项目无法正确地与INET模型链接。您必须在自己的项目的项目属性对话框中选择INET作为项目引用。这样会将INET的include文件夹添加到include路径，因此您只需要（正确地）只写

#include "inet/applications/udpapp/UdpBasicApp.h"

代替

#include "../../inet/src/inet/applications/udpapp/UdpBasicApp.h"

并且还将修改链接器命令行以正确地与INET共享库链接。

如何在Omnet ++（inet）中编写从UdpBasicApp派生的自己的应用程序？
