Why when running .exe file has 2 windows pop up

[Christian Ehrlicher]

Looks like you have CONFIG += console in your pro file

Dear Sir,

This is my .pro file, absolutely no CONFIG += console

Thanks !

QZXing.pri

Maybe in there.

You can remove a config option with

CONFIG -= debug

Add this just before your SOURCES +=

@Christian-Ehrlicher

Thank Sir !

I don't speak English well, am I doing this right, it still doesn't work

QT += core gui
QT += testlib
QT += multimedia multimediawidgets
QT += printsupport

CONFIG += staticlib
CONFIG += qzxing_qml
CONFIG += qzxing_multimedia
CONFIG -= debug
include(QZxing-master/src/QZXing.pri)

[Christian Ehrlicher]

@DQUY05 As I already said maybe CONFG += console is added in QZXing.pri, so removing it before including the pri-file will not help at all...

@Christian-Ehrlicher

Dear Sir,

Even if I don't use QZXing, the error is still the same
Could it be due to another reason?

Thanks !

#CONFIG += staticlib
#CONFIG += qzxing_qml
#CONFIG += qzxing_multimedia
#include(QZxing-master/src/QZXing.pri)

Hi, if you build it for Release (not Debug) do you still get 2 windows?

[DQUY05]

@hskoglund

Yes Sir,


[Bonnie]

That's probably because that QT += testlib
Qt test should only be used in unit testing, not in real application.

[DQUY05]

@Bonnie
Thank Sir,

indeed it was caused by QT += testlib, I'm glad the problem is solved
