i m using
qt-win-opensource-4.2.2-mingw.exe on win xp

i have done every installation and environ variable setting.

i ran this prgram:

Qt Code:

Switch view

#include <QApplication>
 #include <QLabel>
 int main(int argc, char *argv[])
 {
     QApplication app(argc, argv);
     QLabel *label = new QLabel("Hello Qt!");
     label->show();
     return app.exec();
 }

#include <QApplication>
 #include <QLabel>
 int main(int argc, char *argv[])
 {
     QApplication app(argc, argv);
     QLabel *label = new QLabel("Hello Qt!");
     label->show();
     return app.exec();
 }

To copy to clipboard, switch view to plain text mode

then performed following steps:
i saved it in this dir:
D:\qt ex\hello

then on command -prompt:

D:\qt ex\hello>qmake -project

D:\qt ex\hello>qmake hello.pro

D:\qt ex\hello>make
mingw32-make -f Makefile.Release
