OpenCV with Qt：程序意外完成 [英] OpenCV with Qt: The program has unexpectedly finished

问题描述

我试图在Windows 8 64bit配置OpenCV与Qt Creator 2.7.0（Qt 5.0.2）。
在执行程序时，出现以下错误：

I am trying to configure OpenCV with Qt Creator 2.7.0 (Qt 5.0.2) on windows 8 64bit. While executing my program, I get the following error:

程序意外完成。

The program has unexpectedly finished.

这是我的main.cpp

This is my main.cpp

#include "mainwindow.h"
#include <QApplication>
#include <opencv2/core/core.hpp>
#include <opencv2/highgui/highgui.hpp>

using namespace cv;
int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    MainWindow w;
    w.show();
    IplImage *image = cvLoadImage("E:\\lena.jpg"); //If this is removed, the program runs OK
    return a.exec();
}

我的.pro文件是

QT       += core gui

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

TARGET = untitled1
TEMPLATE = app


SOURCES += main.cpp\
        mainwindow.cpp

HEADERS  += mainwindow.h

FORMS    += mainwindow.ui

unix:!mac {
    message("* Using settings for Unix/Linux.")
    INCLUDEPATH += /usr/local/include/opencv

    LIBS += -L/usr/local/lib/ \
        -lopencv_core \
        -lopencv_highgui \
        -lopencv_imgproc
}

## OpenCV settings for Mac OS X
macx {
    message("* Using settings for Mac OS X.")
    INCLUDEPATH += /usr/local/include/opencv

    LIBS += -L/usr/local/lib/ \
        -lopencv_core \
        -lopencv_highgui \
        -lopencv_imgproc
}

## OpenCV settings for Windows and OpenCV
win32 {
    message("* Using settings for Windows.")
    INCLUDEPATH += "C:\\OpenCV\\opencv\\build\\include" \
                   "C:\\OpenCV\\opencv\\build\\include\\opencv" \
                   "C:\\OpenCV\\opencv\\build\\include\\opencv2"

    LIBS += -L"C:\\OpenCV\\opencv\\build\\x64\\mingw\\lib" \
        -lopencv_core244 \
        -lopencv_highgui244 \
        -lopencv_imgproc244
}

环境变量包括：

OPENCV_DIR：C：\OpenCV\opencv\build\x64\ b G：\5.0.2\Tools\MinGW\bin; G：\Qt\5.0.2\mingw47_32\bin

OPENCV_DIR:C:\OpenCV\opencv\build\x64\mingw Path: G:\5.0.2\Tools\MinGW\bin;G:\Qt\5.0.2\mingw47_32\bin

这可能是什么问题？

推荐答案

您可能需要更改

-lopencv_core244 \
-lopencv_highgui244 \
-lopencv_imgproc244

到

-lopencv_core244d \
-lopencv_highgui244d \
-lopencv_imgproc244d

• （如果您要在调试中构建）
