由于缺少"libgcc_s_dw2-1.dll"，OpenCV程序无法运行.在Code :: Block中 [英] OpenCV program cannot run because of missing "libgcc_s_dw2-1.dll" in Code::Block

问题描述

我编写了一个简单的OpenCV程序，尝试在同一目录中打开图像"kindle-fire-hd.jpg". IDE是Code :: Block，版本OpenCV是2.4.2，编译器是MinGW，它是Code :: Block的组件.代码显示在这里:

I write a simple OpenCV program that tries to open an image "kindle-fire-hd.jpg" in the same directory. The IDE is Code::Block and the version OpenCV is 2.4.2 and the compiler is MinGW which is attached as the component of Code::Block. The code is shown here:

#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] : "kindle-fire-hd.jpg", 1);
  if (im.empty())
  {
    cout << "Cannot open image!" << endl;
    return -1;
  }

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

  return 0;
}

它可以正确地构建和编译(没有任何错误和警告消息)，并且我已经按照

It can be built and compiled correctly (without any error and warning messages) and I have configured the Code::Block as that said in Getting started with OpenCV 2.4 and MinGW on Windows 7 .

但是，当我运行"该程序时.它显示缺少libgcc_s_dw2-1.dll"消息.

However, when I "run" this program. it shows a "missing libgcc_s_dw2-1.dll" message.

然后，当我单击确定"按钮时，控制台窗口将显示以下消息:

And, when I click the "OK" button, the console window shows the following message:

我尝试搜索关于stackoverflow的相关问题，但是所有问题的解决方案都无法解决此问题.谢谢.

I tried to search the related Questions on stackoverflow but all their solutions cannot fix this problem. Thanks.

推荐答案

最后，我解决了这个问题！

Finally, I fix this problem!

导致此缺少dll"问题的原因是与Code :: Block相连的MinGW编译器不完整.因此，您需要将所需的DLL文件下载到目录"C:\ Program Files(x86)\ CodeBlocks \ MinGW \ libexec \ gcc \ mingw32 \ 4.4.1"，还需要将此目录的路径添加到系统PATH环境变量.

This reason that causes this "missing dll" problem is the MinGW compiler attached with the Code::Block is not complete. So, you need to download the required DLL files to the directory "C:\Program Files (x86)\CodeBlocks\MinGW\libexec\gcc\mingw32\4.4.1" which you also need to add the path of this directory to the system PATH environment variable.

在这种情况下，即使只有一个关于libgcc_s_dw2-1.dll的错误消息丢失，我也会下载两个DLL文件:libgcc_s_dw2-1.dll和libstdc ++-6.dll.如果您忘记第二个libstdc ++-6.dll，则在运行该程序时会收到另一条丢失的消息.

In this case, I download two DLL files: libgcc_s_dw2-1.dll and libstdc++-6.dll even if there is only one missing error message about libgcc_s_dw2-1.dll. If you forget the second one, libstdc++-6.dll, you will get another missing message when run the program.

第一个dll libgcc_s_dw2-1.dll可能会引起如下问题:

The first dll, libgcc_s_dw2-1.dll, can be fond at the question Where Can I Get libgcc_s_dw2-1.dll?, in which the download link is listed in the selected answer by the author rodrigo. Thanks the guy!

第二个dll libstdc ++-6.dll可以在

The second dll, libstdc++-6.dll, can be downloaded at http://sourceforge.net/projects/mingw/files/MinGW/Base/gcc/Version4/gcc-4.6.2-1/libstdc%2B%2B-4.6.2-1-mingw32-dll-6.tar.lzma/download
