小编Kel*_*rim的帖子

好吧，我需要开始使用 OpenCV，并且由于我习惯了使用 QtCreator，我正在努力让它们一起工作。我下载了最新的OpenCV版本，并用MinGW编译它。然后，我创建了这个小控制台项目来尝试一下。以下是.pro文件：

QT       += core
QT       -= gui
TARGET = OpenCV_test4
CONFIG   += console
CONFIG   -= app_bundle
TEMPLATE = app
SOURCES += main.cpp
INCLUDEPATH += C:\\Librerias\\opencv2.3.1\\release\\include
LIBS += -LC:\\Librerias\\opencv2.3.1\\release\\lib \
    -lopencv_core231.dll \
    -lopencv_highgui231.dll \
    -lopencv_imgproc231.dll \
    -lopencv_features2d231.dll \
    -lopencv_calib3d231.dll

这是main.cpp文件：

#include <QtCore/QCoreApplication>
#include <opencv2/core/core.hpp>
#include <opencv2/highgui/highgui.hpp>

int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);

    // read an image
    cv::Mat image= cv::imread("img.jpg");
    // create image window named "My Image"
    cv::namedWindow("OpenCV Window");
    // show the image …
