Error on debug : Qwt 6.0.1

Hi everybody,

when trying to compile my application with qwt, in debug mode, I get this error message on runtime :

Quote:

---

QWidget: Must construct a QApplication before a QPaintDevice

---

The bug doesn't come from my application since even when doing :

Quote:

---

QApplication app(argc, argv);
QDialog dialog;
dialog.show();
return app.exec();

---

I'm still getting this error message.

However, it works great on release mode.

That's because you are using a Qt library, that was built in release mode.
