“程序无法启动，因为您的计算机缺少 opencv_world300.dll"C++ 中的错误 [英] "The program can't start because opencv_world300.dll is missing from your computer" error in C++

问题描述

我想在 Visual Studio 2013 中编译一个 opencv Console C++ 程序.这是我的代码:

I want to compile an opencv Console C++ program in Visual Studio 2013. This is my code:

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

using namespace cv;
using namespace std;

int main(int argc, const char** argv)
{
    Mat img = imread("rgb_1.png", CV_LOAD_IMAGE_UNCHANGED); //read the image data in the file "MyPic.JPG" and store it in 'img'

    if (img.empty()) //check whether the image is loaded or not
    {
        cout << "Error : Image cannot be loaded..!!" << endl;
        //system("pause"); //wait for a key press
        return -1;
    }

    namedWindow("MyWindow", CV_WINDOW_AUTOSIZE); //create a window with the name "MyWindow"
    imshow("MyWindow", img); //display the image which is stored in the 'img' in the "MyWindow" window

    waitKey(0); //wait infinite time for a keypress

    destroyWindow("MyWindow"); //destroy the window with the name, "MyWindow"

    return 0;
}

虽然我已经在 Computer 和 Visual Studio 目录中的属性中定义了所有目录，但我收到以下错误:

Although I have defined all the directories in properties both in Computer and Visual Studio directories, I get the following error:

程序无法启动，因为您的计算机缺少 opencv_world300.dll."

"The program can't start because opencv_world300.dll is missing from your computer."

我该如何解决这个问题?

How can I fix this problem?

推荐答案

windows 下可以复制:

Under windows you can copy it from:

<your install directory>opencv30uildx64vc12in

并将其放入您的 Visual Studio 解决方案中(我假设您使用的是 x64/Release 配置):

And put it in your Visual Studio solution (I assume you are using a x64/Release configuration):

<your solution directory>x64Release

或者你可以将上面的 OpenCV 添加到你的 PATH 环境变量中

Or you you can add the above OpenCV to your PATH environment variable
