QCoreApplication problem

[probine]

I just want to use the variables given in the command line. This is the code:

#include <QCoreApplication>
#include <iostream>
 
#include "server.h"
using namespace std;
 
Server::Server(){
  cout << "InfoSpeed server beta 0.9\n";
  QString listenIp = QCoreApplication::arguments().at(1);
}
 
Server::~Server(){
 
}

#include <QCoreApplication>
#include <iostream>
 
#include "server.h"
using namespace std;

Server::Server(){
  cout << "InfoSpeed server beta 0.9\n";
  QString listenIp = QCoreApplication::arguments().at(1);
}

Server::~Server(){

}

To copy to clipboard, switch view to plain text mode 

This simple code gives me this error:

server.cpp: In constructor `Server::Server()':
server.cpp:18: error: invalid use of undefined type `struct QStringList'
E:/qt/include/QtCore/../../src/corelib/tools/qstring.h:64: error: forward declaration of `struct QStringList'

What is wrong ?

Add #include <QStringList>.
