qrc resources are not available during debug build

Qt 5.0 windows

debug build of my program can't load png image from resources. Widget that supposed to show it stays empty. But when i switch to Release build the image appears just fine.
Also when I use direct path like "c://image.png" then it works too.

I did not modify any build parameters and got fresh installation of Qt 5.0.

do i need to add something to my project settings?

Please prepare a minimal compilable example reproducing the problem.

main.cpp

Code:

---

#include <QApplication>
#include <QGraphicsScene>
#include <QGraphicsView>
#include <QGraphicsPixmapItem>
 
int main(int argc, char *argv[])
{
 
        QApplication a(argc, argv);
        QGraphicsScene scene;
        QGraphicsView view(&scene);
        QGraphicsPixmapItem item(QPixmap(":/images/wearepros.png")); //doesn't load during debug build
        scene.addItem(&item);
        view.show();
        return a.exec();
}

---

res.qrc

Code:

---

<RCC>
    <qresource prefix="/images">
        <file>sample.jpg</file>
        <file>wearepros.png</file>
        <file>sample.bmp</file>
    </qresource>
</RCC>

What about the project file?

Code:

---

#-------------------------------------------------
#
# Project created by QtCreator 2012-12-23T13:46:35
#
#-------------------------------------------------
 
QT       += core gui
 
greaterThan(QT_MAJOR_VERSION, 4): QT += widgets
 
TARGET = test3
TEMPLATE = app
 
 
SOURCES += main.cpp\
        mainwindow.cpp
 
HEADERS  += mainwindow.h
 
FORMS    += mainwindow.ui
 
RESOURCES += \
    res.qrc

---

I created project via New Project->Qt gui project. Then replaced main.cpp with my code and left everything else as it was. then did Add new ->qt resource, added prefix and files.

Added after 7 minutes:

I uploaded my project's folder if you like
http://rghost.net/42458531

The code looks ok and it works fine for me both in release and debug (on Linux though, however this shouldn't matter).

Please check if the final size of your debug executable changes depending on whether RESOURCES += res.qrc exists in your project file or not.

Nope it does not change. it always stays 56kb

release one does change. it is 11kb without "RESOURCES +=" line in pro and 275kb with it.

Try cleaning the project completely, run qmake and make again. Do you get any warnings during compilation?

thank you wysota.

I re installed Qt completely and it's now working and showing resources.
