No output to console

I'm having problem getting output of this simple program in the console in w2k. In Linux, no problem, I get the expected lines. Can anyone find a problem with this? Why isn't there any output?

Add "CONFIG += console" to your .pro file.

No need to create a QApplication or QCoreApplication?

No. The console is independent of Qt.

Thank you all! Your patience with all my problems is incredible.:)

I have a similar program(see below), and I do add "config += console" for qmake. but I can only get the first output but not the second output. Does anyone can help me?

Mingw 3.4.5 + Windows Vista Home

Code:

---

#include <QProcess>
#include <QString>
#include <QByteArray>
#include <QTextStream>
#include <QDebug>
 
int main(int argc, char** argv){
  QTextStream out(stdout);
  out<<"[result]"<<endl<<flush;
  qDebug()<<"debug output"<<endl;
 
  QProcess* p;
  p=new QProcess();
  p->start("dir");
  if (!p->waitForFinished())
    return -1;
  QByteArray b;
  b=p->readAll();
  out<<QString(b)<<endl;
  qDebug()<<QString(b);
  out<<"[end]"<<endl;
  qDebug()<<"debug end";
  return 0;
}

Probably QProcess::waitForFinished() fails and the execution flow doesn't reach the second part of main(). Create QCoreApplication (or QApplication) instance at the beginning of main().
