在Windows 7 x64上安装OpenCV2.4.1 - Mingw＆amp;码块

您好，我按照本教程

Getting started with OpenCV 2.4 and MinGW on Windows 7

我配置相同，除了x86，我把x64。

这是示例

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

using namespace cv;
using namespace std;

int main(int argc, char** argv)
{
Mat im = imread(argc == 2 ? argv[1] : "lena.jpg", 1);
if (im.empty())
{
cout << "Cannot open image!" << endl;
return -1;
}

imshow("image", im);
waitKey(0);

return 0;
}

当我编译main.cpp

时

C：\ Users \ rgap \ Desktop＆gt; g ++ -I“C：\ opencv \ build \ include”-L“C：\ opencv \ build \ x64 \ mingw \ lib”main.cpp -lope ncv_core241 -lopencv_highgui241 -o main

我收到以下错误

C:\Users\rgap\AppData\Local\Temp\ccDgmPAT.o:main.cpp:(.text+0x62): undefined reference to `cv::imread(

collect2: ld devolvió el estado de salida 1

这是一个错误吗？：（

谢谢：）
