Question

我正在使用Dev C ++ 4.9.9.2和OpenCV 2.4.8，我也在使用Windows 7 x86。这些都在我的编译器设置中，-L"D:\opencv\build\x86\vc12\bin" -lopencv_highgui248 -lopencv_core248 -lopencv_flann248 -lopencv_gpu248 -lopencv_imgproc248 -lopencv_legacy248 -lopencv_ml248 -lopencv_nonfree248 -lopencv_objdetect248 -lopencv_photo248 -lopencv_video248 -lopencv_ts248.每次编译我的简单项目时，都会显示以下错误：编译器：

编辑：有我的代码。

include <opencv2/opencv.hpp> 
#include <iostream>
#include <io.h>

using namespace cv;
using namespace std;

int main (int, char**) 
{
  cv::VideoCapture camera(1); 
  if(!camera.isOpened())
  {
    std::cerr << "ERROR: Could not open camera" << std::endl;
    return 1;
  }
  cv::namedWindow("Webcam", CV_WINDOW_AUTOSIZE);
  while(1)
  {
    cv::Mat frame;
    camera >> frame;
    cv::imshow("Webcam", frame);
    if (cv::waitKey(30) >= 0) 
    {
        imwrite("test.jpg", frame);
        break;
    }
  }
  return 0;
}

执行终止

你能帮我解决这个问题吗？请。感谢。
