c++ - Visual Studio 2012 错误 : The application was unable to start correctly (0xc0000007b)

Question

我正在尝试运行一个 opencv 程序。我已经相应地配置了 opencv，但我收到 Visual Studio 2012 错误“应用程序无法正确启动 (0xc0000007b)。”

以下是我要运行的代码。

#include "opencv2/highgui/highgui.hpp"
#include <iostream>

using namespace cv;
using namespace std;

int main(int argc, char* argv[])
{
    VideoCapture cap(0); // open the video camera no. 0

    if (!cap.isOpened())  // if not success, exit program
    {
        cout << "Cannot open the video file" << endl;
        return -1;
    }

    //get the width of frames of the video
    double dWidth = cap.get(CV_CAP_PROP_FRAME_WIDTH); 

    //get the height of frames of the video
    double dHeight = cap.get(CV_CAP_PROP_FRAME_HEIGHT); 

    cout << "Frame size : " << dWidth << " x " << dHeight << endl;

    namedWindow("MyVideo",CV_WINDOW_AUTOSIZE); //create a window called "MyVideo"

    while (1)
    {
        Mat frame;

        bool bSuccess = cap.read(frame); // read a new frame from video

        if (!bSuccess) //if not success, break loop
        {
            cout << "Cannot read a frame from video file" << endl;
            break;
        }

        imshow("MyVideo", frame); //show the frame in "MyVideo" window

        //wait for 'esc' key press for 30ms. If 'esc' key is pressed, break loop
        if (waitKey(30) == 27) 
        {
            cout << "esc key is pressed by user" << endl;
            break; 
        }
    }
    return 0;
}

您可能没有正确包含所有库。使用 Dependency Walker检查你是否遗漏了什么。
