OpenCV - DLL丢失，但它不是？ [英] OpenCV - DLL missing, but it's not?

问题描述

我正在尝试只有一个基本的程序与OpenCV与以下代码：

  #includecv.h
 #includehighgui.h
 
 int main（）
 {
 IplImage * newImg; 
 newImg = cvLoadImage（〜/ apple.bmp，1）; 
 cvNamedWindow（Window，1）; 
 cvShowImage（Window，newImg）; 
 cvWaitKey（0）; 
 cvDestroyWindow（Window）; 
 cvReleaseImage（& newImg）; 
 return 0; 
} 
  

当我运行这个，我得到

程序无法启动，因为
libcxcore200.dll从
计算机中丢失。请尝试重新安装
程序以解决此问题。

但是，我可以看到这个DLL。它存在。我已经加入以下为我的链接

C时输入的依赖关系：\OpenCV2.0\lib\libcv200.dll。 a
C：\OpenCV2.0 \lib\libcvaux200.dll.a
C：\OpenCV2.0\lib\libcxcore200.dll.a
C：\\ \\ OpenCV2.0 \lib\libhighgui200.dll.a

有什么好处？我使用visual studio 2008。

当我链接.dll文件而不是.dll.a文件时，我得到

致命错误LNK1107：无效或损坏
文件：无法读取0x3F8
libcv200.dll

解决方案

我按照 http：/ /opencv.willowgarage.com/wiki/VisualC%2B%2B_VS2010 ，但仍然坚持完全相同的问题，所以这里是我如何解决它。

1. 获取MSVC 2010 express版本。




2. Win 32 OpenCV 2.2二进制文件并安装在默认位置。




3. 已创建新项目。




4. 项目设置

   
   
   

   项目 - > OpenCV_Helloworld属性...配置属性 - > VC ++目录

   
   
   

   包含目录。 .. add： C：\OpenCV2.2 \include\;

   
   
   

   add： C：\OpenCV2.2\lib; C：\OpenCV2.2\bin;

   
   
   

   源目录...添加：

     C：\OpenCV2.2 \modules\calib3d\src; C：\OpenCV2.2\modules\contrib\src; C：\OpenCV2.2\modules\core\src; C：\OpenCV2.2\modules\features2d\src ; C：\OpenCV2.2\modules\flann\src; C：\OpenCV2.2\modules\gpu\src; C：\OpenCV2.2\modules\gpu\ SRC; C：\OpenCV2.2\modules\highgui\src; C：\OpenCV2.2\modules\imgproc\src; C：\OpenCV2.2\modules\legacy\\ \\src; C：\OpenCV2.2\modules\ml\src; C：\OpenCV2.2\modules\objdetect\src; C：\OpenCV2.2\modules\video \src; 
    

   链接器 - >输入 - >其他依赖关系...

   
   
   

   建立调试......添加：

     opencv_calib3d220d.lib; opencv_contrib220d.lib; opencv_core220d.lib; opencv_features2d220d .LIB; opencv_ffmpeg220d.lib; opencv_flann220d.lib; opencv_gpu220d.lib; opencv_highgui220d.lib; opencv_imgproc220d.lib; opencv_legacy220d.lib; opencv_ml220d.lib; opencv_objdetect220d.lib; opencv_video220d.lib; 
     






此时我以为我已经完成了，但遇到了您在调试模式下运行exe时描述的问题。最后一步很明显，一旦你看到它，选择：

Linker - > General ...将使用库依赖性输入设置为 b
$ b

希望这有帮助。

I am trying just a basic program with OpenCV with the following code:

#include "cv.h"
#include "highgui.h"

int main()
{
    IplImage* newImg;
    newImg = cvLoadImage("~/apple.bmp", 1);
    cvNamedWindow("Window", 1);
    cvShowImage("Window", newImg);
    cvWaitKey(0);
    cvDestroyWindow("Window");
    cvReleaseImage(&newImg);
    return 0;
}

When I run this, I get

The program can't start because libcxcore200.dll is missing from your computer. Try reinstalling the program to fix this problem.

However, I can see this DLL. It exists. I have added the following to the input dependencies for my linker

C:\OpenCV2.0\lib\libcv200.dll.a C:\OpenCV2.0\lib\libcvaux200.dll.a C:\OpenCV2.0\lib\libcxcore200.dll.a C:\OpenCV2.0\lib\libhighgui200.dll.a

What gives? I'm using visual studio 2008.

When I link the .dll files instead of .dll.a files, I get

fatal error LNK1107:invalid or corrupt file: cannot read at 0x3F8 libcv200.dll

解决方案

I followed instructions on http://opencv.willowgarage.com/wiki/VisualC%2B%2B_VS2010 but was still stuck on exactly the same problem, so here's how I resolved it.

1. Fetched MSVC 2010 express edition.

2. Fetched Win 32 OpenCV 2.2 binaries and installed in default location.

3. Created new project.

4. Project setup

   Project -> OpenCV_Helloworld Properties...Configuration Properties -> VC++ Directories

   Include Directories... add: C:\OpenCV2.2\include\;

   Library Directories... add: C:\OpenCV2.2\lib;C:\OpenCV2.2\bin;

   Source Directories... add:

   C:\OpenCV2.2\modules\calib3d\src;C:\OpenCV2.2\modules\contrib\src;C:\OpenCV2.2\modules\core\src;C:\OpenCV2.2\modules\features2d\src;C:\OpenCV2.2\modules\flann\src;C:\OpenCV2.2\modules\gpu\src;C:\OpenCV2.2\modules\gpu\src;C:\OpenCV2.2\modules\highgui\src;C:\OpenCV2.2\modules\imgproc\src;C:\OpenCV2.2\modules\legacy\src;C:\OpenCV2.2\modules\ml\src;C:\OpenCV2.2\modules\objdetect\src;C:\OpenCV2.2\modules\video\src;
   

   Linker -> Input -> Additional Dependencies...

   For Debug Builds... add:

   opencv_calib3d220d.lib;opencv_contrib220d.lib;opencv_core220d.lib;opencv_features2d220d.lib;opencv_ffmpeg220d.lib;opencv_flann220d.lib;opencv_gpu220d.lib;opencv_highgui220d.lib;opencv_imgproc220d.lib;opencv_legacy220d.lib;opencv_ml220d.lib;opencv_objdetect220d.lib;opencv_video220d.lib;
   

At this point I thought I was done, but ran into the problem you described when running the exe in debug mode. The final step is obvious once you see it, select:

Linker -> General ... Set 'Use Library Dependency Inputs' to 'Yes'

Hope this helps.
