opencv - 简历.h : file not found opencv

Question

我正在运行这段代码:

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

using namespace cv; 
using namespace std;

int main( int argc, char** argv ) {
    if( argc != 2)
    {
     cout <<" Usage: display_image ImageToLoadAndDisplay" << endl;
     return -1;
    }

    Mat image;
    image = imread(argv[1], CV_LOAD_IMAGE_COLOR);   // Read the file

    if(! image.data )                              // Check for invalid input
    {
        cout <<  "Could not open or find the image" << std::endl ;
        return -1;
    }

    namedWindow( "Display window", CV_WINDOW_AUTOSIZE );// Create a window for display.
    imshow( "Display window", image );                   // Show our image inside it.

    waitKey(0);                                          // Wait for a keystroke in the window
    return 0; }

但它对我不起作用，因为当我编写 cmake 时它会在我的屏幕上显示此错误。在终端:

cv.h: file not found.

谁能帮帮我？它在一个月前工作。

你有链接问题，试试这个；

g++ `pkg-config --cflags --libs opencv` filename.cpp -o filename
