Using OS scope before setting MAKEFILE_GENERATOR

[stephane]

Hello,

I have downloaded and installed Qt as I'm learning how to use it. So, I created a new project myfristqt (empty project). I then added a main.cpp file with this code:

#include <QApplication>

int main(int argc, char *argv[])
{
QApplication app(argc, argv);
return app.exec();
}

First thing I noticed #include <QApplication> line is hightlighted with a red line as if QApplication was an unknown identifier. So, I compiled it to see what happens and here's the error I got:

(internal):1: error : Using OS scope before setting MAKEFILE_GENERATOR

Any idea why this is happening ? I'm using Windows XP

hx for helping,

Stephane

How are you trying to build that project of yours?
