Build a project in command prompt

arash19

Hi forum
I just starting self study on Qt
I am trying the first example in book " c++gui programming with qt 4-2nd edition By Jasmin Blanchette; Mark Summerfield"
#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();
}

My Qt is the latest version
can somebody tel me how to build this simple project in command line?
I tried and had this error
" project error: failed to parse default search path from compiler output"

Hi and welcome to the forums
Normally you would have a . pro file also ? ( a project file)

Why not just use QtCreator ( the Editor ) and make a default project from the New project menu
and then put your code in its main.cpp.
That way linking to the Qt libraries and and other stuff is already in order.

Hi and welcome to devnet,

To add to @mrjj :

1) qmake -project "QT += widgets"
2) qmake
3) make

The first one will create a project with the required Qt module for widgets.
The second will create the Makefile.
The third trigger the compilation.
