无法使用opencv库运行C ++程序(Can't run a C++ program with opencv library)

我为opencv编写了一个简单的测试程序,看看它是否在我在Visual Studio 2010专业版中编译我的OpenCV 2.4之后才能正常工作。

该计划如下:

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

using namespace cv;
using namespace std;

int main()
{
    Mat im = imread("c:/full/path/to/lena.jpg");
    if (im.empty()) 
    {
        cout << "Cannot load image!" << endl;
        return -1;
    }
    imshow("Image", im);
    waitKey(0);
}

问题是程序编译没有问题(我已经设置了所有的lib路径并在visual studio中包含路径),但是当我尝试运行它时,它给了我以下错误信息winow:“程序无法启动因为您的计算机缺少opencv_core240d.dll。请尝试重新安装该程序以解决此问题“

现在,我已经读过这可以通过执行cmd命令将windows PATH变量设置为实际.dll文件所在的目录来解决:

SET PATH="C:\Program Files (x86)\OpenCV\opencv\build\bin\Debug"

指定的路径确实是.dll文件所在的路径,但是,我仍然得到错误。

真的很感激,因为我花了太多时间在这周围徘徊......


I wrote a simple test program for opencv to see if it's working after I compiled my OpenCV 2.4 in visual studio 2010 pro.

The program goes like this:

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

using namespace cv;
using namespace std;

int main()
{
    Mat im = imread("c:/full/path/to/lena.jpg");
    if (im.empty()) 
    {
        cout << "Cannot load image!" << endl;
        return -1;
    }
    imshow("Image", im);
    waitKey(0);
}

The thing is that the program compiles without problems ( I've set all the lib paths and include paths in visual studio), but when I try to run it, it gives me the following error message winow: "The program can't start because opencv_core240d.dll is missing from your computer. Try reinstalling the program to fix this problem"

Now, I've read that this could be solved by setting the windows PATH variable to the directory where the actual .dll file is located by doing a cmd command:

SET PATH="C:\Program Files (x86)\OpenCV\opencv\build\bin\Debug"

The path specified is indeed the path where the .dll file is located however, I still get the error.

Help would really be appreciated since I've spent far too much time cocking around this...

您需要一个<form>元素才能触发onsubmit事件。 将<input>元素包装在表单中,它将起作用。

<form>
<!-- Start Search -->
<div class="top-search">
<div class="container">
    <div class="input-group">
        <span class="input-group-addon"><i class="fa fa-search"></i></span>
        <input id="search" type="text" class="form-control" placeholder="Search">
        <span class="input-group-addon close-search"><i class="fa fa-times"></i></span>
    </div>
</div>
</div>
<!-- End Search -->
</form>

You need a <form> element in order for the onsubmit event to be triggered. Wrap the <input> element in a form and it will work.

<form>
<!-- Start Search -->
<div class="top-search">
<div class="container">
    <div class="input-group">
        <span class="input-group-addon"><i class="fa fa-search"></i></span>
        <input id="search" type="text" class="form-control" placeholder="Search">
        <span class="input-group-addon close-search"><i class="fa fa-times"></i></span>
    </div>
</div>
</div>
<!-- End Search -->
</form>
