测试代码：

<pre class="cpp" name="code">#include <opencv2/core/core.hpp>
#include <opencv2/highgui/highgui.hpp>

int main() {
// read an image
cv::Mat image= cv::imread("img.jpg");
// create image window named "My Image"
cv::namedWindow("My Image");
// show the image on window
cv::imshow("My Image", image);
// wait key for 5000 ms
cv::waitKey(5000);

return 0;
}

出现错误：

error: undefined reference to `cv::imread(std::string const&, int)'
