Question

我想将opencv249与Qt 5.5集成。我的.pro文件是这样的：

INCLUDEPATH += C:/OpenCV249/opencv/build/include
INCLUDEPATH += C:/OpenCV249/opencv/build/include/opencv
INCLUDEPATH += C:/OpenCV249/opencv/build/include/opencv2

LIBS += -LC:/OpenCV249/opencv/build/x86/vc12/lib

LIBS += -lopencv_core249 -lopencv_highgui249 -lopencv_imgproc249 -lopencv_features2d249 -lopencv_calib3d249

我的代码是这样的：

#include "opencv2/highgui/highgui.hpp"
#include "opencv2/imgproc/imgproc.hpp"
#include "opencv2/core/core.hpp"

using namespace cv;

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

    Mat im=imread("1.jpg");
    imshow("kubi",im);  

    return a.exec();
}

它给出了这些错误：

    main.obj:-1: error: LNK2019: unresolved external symbol "void __cdecl cv::fastFree(void *)" (?fastFree@cv@@YAXPEAX@Z) referenced in function "public: __cdecl cv::Mat::~Mat(void)" (??1Mat@cv@@QEAA@XZ)

    debug\Sercan.exe:-1: error: LNK1120: 6 unresolved externals

我不知道如何修复它。

你的lib路径是否正确？

你应该改变吗？

LIBS += -LC:/opencv/build/x86/vc12/lib

与

LIBS += -LC:/OpenCV249/opencv/build/x86/vc12/lib

这只是一个疯狂的猜测，其他一切看起来都不错......

无法将Opencv与Qt集成
