程序无法启动，因为缺少 opencv_core2410d.dll

Question

我安装了 visual studio 2012。我有 windows 8.1.then 我提取 opencv 2.4.10在c分区。

创建了可视化 C++ 项目->win32 控制台应用程序。

因为我有 x64 机器

 build menu->Configuration manager->platform->x64

然后我在我的 vs 项目中设置以下配置。

project->properties->configuration->all configuration

VC++Directories->Library Directories->
  C:\opencv\build\x64\vc11\bin,C:\opencv\build\x64\vc11\lib

C/C++->Genaral->Additional Include Derectories->
    C:\opencv\build\include,C:\opencv\build\include\opencv2,C:\opencv\build\include\opencv

改变

          Configuration->Debug
          Select Linker->Input->Additional Dependencies

    opencv_core2410d.lib
    opencv_highgui2410d.lib
    opencv_imgproc2410d.lib
    opencv_calib3d2410d.lib
    opencv_contrib2410d.lib
    opencv_features2d2410d.lib
    opencv_flann2410d.lib
    opencv_gpu2410d.lib
    opencv_legacy2410d.lib
    opencv_ml2410d.lib
    opencv_nonfree2410d.lib
    opencv_objdetect2410d.lib
    opencv_photo2410d.lib
    opencv_stitching2410d.lib
    opencv_superres2410d.lib
    opencv_ts2410d.lib
    opencv_video2410d.lib

然后

   change Configuration->Release
   select Linker->Input->Additional Dependencies

    opencv_core2410.lib
    opencv_highgui2410.lib
    opencv_imgproc2410.lib
    opencv_calib3d2410.lib
    opencv_contrib2410.lib
    opencv_features2d2410.lib
    opencv_flann2410.lib
    opencv_gpu2410.lib
    opencv_legacy2410.lib
    opencv_ml2410.lib
    opencv_nonfree2410.lib
    opencv_objdetect2410.lib
    opencv_photo2410.lib
    opencv_stitching2410.lib
    opencv_superres2410.lib
    opencv_ts2410.lib
    opencv_video2410.lib
    opencv_videostab2410.lib

然后我创建了一个class并编写了代码

    #include "stdafx.h"
    #include "opencv2/highgui/highgui.hpp"
    #include "opencv2/core/core.hpp"

    int main(){
       //declare a new iplimage pointer
       IplImage*myimage;

       //load image
       myimage = cvLoadImage("D:\visual studio 2012\katussa.jpg",1);
       cvNamedWindow("Smile",1);
       cvShowImage("Smile",myimage);

       //wait for the key to close the window
       cvWaitKey(0);
       cvDestroyWindow("Smile");
       cvReleaseImage(&myimage);
       return 0;
    }

当我运行收到错误消息时 程序无法启动，因为缺少 opencv_core2410d.dll。

Answer 1

您需要将 OpenCV 添加到您的系统路径：

您需要将目录 C:\opencv\build\x86\vc10\bin 添加到您的系统 PATH 中。此目录包含运行您的代码所需的 OpenCV DLL。

打开控制面板→系统→高级系统设置→高级选项卡→环境变量...

在系统变量部分，select 路径 (1)，编辑 (2)，然后键入 C:\opencv\build\x86\vc10\bin； (3)、然后点击确定。

Answer 2

有时，即使您已将相关的 bin 文件（例如 \opencv-x.x.x\build\install\x64\vc15\bin）添加到系统路径环境变量中，您也可能会遇到此错误。

就我而言，它在我重新启动 PC 后就起作用了。或者可能只是重新启动 visual studio 并在重新启动系统之前查看它是否正常工作。
