如何在可执行文件中嵌入openCV Dll。

How to embedd openCV Dll's in Executable

本文关键字:openCV Dll 可执行文件      更新时间:2023-10-16

我使用openCV编写了一个图像匹配工具(控制台应用程序,没有gui或windows)。我想将我的EXE文件移植到另一台计算机,但它要求opencv dll (opencv_core220.dll, opencv_highgui220.dll,…)

我的问题是怎么做。我觉得有两种方法都很好:
    将opencv重新编译为静态库。Lib而不是.dll)。那没有用。我得到了关于cap_vfw.obj的10个链接错误
  1. 如果可能,如何合并/嵌入DLL到exe文件

我试图使用ILMerge,但它不起作用(错误:无法从a.exe文件加载程序集),因为它是专为。net设计的

注:-我使用visual studio 2005,在windows上,c++编译器,openCV 2.2

我找到了答案。您必须打开原始的openCV项目,并在静态库模式下重新编译所有相关部分。

  • 对每个项目从libjasper开始按字母顺序执行直到opencv_videozlib项目
  • 也做同样的事情
  • 对于每个项目,进入project propertiesconfiguration propertiesgeneralconfiguration type并将其设置为静态库
  • 现在重新编译这些项目。它们将创建许多大的库文件(最多10MB)。这些文件主要位于opencv的modules目录下。你必须找到他们,并复制到目录,当你保存你的常规库文件时,编译dll的。现在是一个棘手的部分
  • 你必须在你的代码中包含更多的库,而不是当你编译dll的
  • 下面是一个例子,你的代码应该是这样的。对不起,它的格式不太好。可能是本页的html错误:
#include "cv.h"
#include "highgui.h"
    using namespace std;
    using namespace cv;
    // Directives to linker to include openCV lib files.
    #ifndef STATIC_LIBRARY_LINK

    }

您要查找的术语是静态链接。"DLL"代表"动态链接库",与静态相反。不能静态链接动态链接的库。你需要一个"普通"的库。

转到您正在构建的项目的属性(在解决方案资源管理器中右键单击项目并选择属性)。现在展开Configuration properties->Linker选项,并在General下设置静态链接库的路径(即,扩展名为.lib)。现在选择Configuration properties->Linker->Input选项,并键入您希望静态链接到的所有库的名称。现在重新构建项目,它们应该被链接到可执行文件中。如果文件的路径不正确,它会警告你。
