未实现 OpenCV SURF 功能的可能重复项
我的错误代码是：
错误 LNK2019：函数 _main 中引用的未解析外部符号“public：__thiscall cv::SURF::SURF(double,int,int,bool,bool)”(??0SURF@cv@@QAE@NHH_N0@Z)
我不知道如何解决它。
我的代码是：
#include <opencv\cv.h>
#include <opencv\highgui.h>
#include <iostream>
#include <conio.h>
#include <opencv2\nonfree\features2d.hpp>
#include <opencv2\legacy\legacy.hpp>
#include <opencv2\core\core.hpp>
#include <stdio.h>

cout << "could not open or find the image" << endl;
