Strange errors

[prykHetQuo]

OS: Ubuntu Linux 8.10 x64

QT version: 4.4.3

The code:

#include <QApplication>
#include <QHttp>
#include <QString>
 
#include <iostream>
 
class Test: public QObject
{
  Q_OBJECT
 
  QHttp objQHttp;
 
  public:
 
  Test(QObject *parent= 0): QObject(parent), objQHttp("ftp.otenet.gr")
 {
   connect(&objQHttp, SIGNAL(dataReadProgress(int, int)), this, SLOT(DisplayProgress(int, int)));
 
   objQHttp.get("/linux/ubuntu-releases/intrepid/ubuntu-8.10-desktop-amd64.iso");
 } 
 
 
  private slots:
  void DisplayProgress(int done, int total)
  {
     std::cout<< done<< " of "<< total<< " has been downloaded so far\n";
  }
};
 
 
int main(int argc, char *argv[])
{
      QApplication app(argc, argv);
 
      Test obj(0);
 
      app.exec();
 
      return 0;
}

#include <QApplication>
#include <QHttp>
#include <QString>

#include <iostream>

class Test: public QObject
{
  Q_OBJECT

  QHttp objQHttp;

  public:
  
  Test(QObject *parent= 0): QObject(parent), objQHttp("ftp.otenet.gr")
 {
   connect(&objQHttp, SIGNAL(dataReadProgress(int, int)), this, SLOT(DisplayProgress(int, int)));

   objQHttp.get("/linux/ubuntu-releases/intrepid/ubuntu-8.10-desktop-amd64.iso");
 } 


  private slots:
  void DisplayProgress(int done, int total)
  {
     std::cout<< done<< " of "<< total<< " has been downloaded so far\n";
  }
};
  

int main(int argc, char *argv[])
{
      QApplication app(argc, argv);

      Test obj(0);

      app.exec();

      return 0;
}

with QT+= network added in the .pro file, produces:

How can this be fixed?

[ComaWhite]

add this to it

#include "test.moc"

#include "test.moc"

To copy to clipboard, switch view to plain text mode 

Add it before the main() and after the Test class. You should seperate this.

...or better use separate files. One for the main function, one test.cpp and one text.h. This would I prefer.
