QT Creator exits with code 0 when running program

I am trying to run a simple OpenCV program in QT Creator 2.3, QT 4.7.4. I know the syntax is correct, but my program does not get run. When I run it, I simply get the qtcreator_process_stub.exe window with "Press <RETURN> to close this window...".

Why is this? My .pro file looks as such:

QT       += core
QT       -= gui

TARGET = myQtConsoleProject
CONFIG   += console
CONFIG   -= app_bundle

TEMPLATE = app
SOURCES += main.cpp

INCLUDEPATH += C:\\opencv\\release\\include

LIBS += -LC:\\opencv\\release\\lib \
-lopencv_core231.dll \
-lopencv_highgui231.dll \
-lopencv_imgproc231.dll \
-lopencv_features2d231.dll \
-lopencv_calib3d231.dll

The application output is

Starting C:\Users\chris\QT\myQtConsoleProject-build-desktop-Qt_4_7_4_for_Desktop_-_MinGW_4_4__Qt_SDK__Release\release\myQtConsoleProject.exe...
C:\Users\chris\QT\myQtConsoleProject-build-desktop-Qt_4_7_4_for_Desktop_-_MinGW_4_4__Qt_SDK__Release

\release\myQtConsoleProject.exe exited with code 0

The contents of my source code is as follows:

#include <stdio.h>
#include <opencv2/core/core.hpp>
#include <opencv2/highgui/highgui.hpp>
int main() {
        printf("not outputting...\n");
        cv::Mat image= cv::imread("C:/temp/i开发者_运维知识库mg.jpg");
        cv::namedWindow("My Image");
        cv::imshow("My Image", image);
        cv::waitKey(50000);
        return 1;
}

I've added C:\opencv\release\bin to my path.

The fact that your console window does not show any lines except the "Press to close" line means that your application does not output anything to the console.

I see you have a console project configured, meaning it has no GUI. But due to the fact that your program compiles fine this might not be a problem.

Can you post the code of your main() function? The behavior you describe seems to be related to your code, not the project configuration.
