如何使用OpenCV 2.4.3与Code :: Blocks编译程序？ [英] How to compile a program using OpenCV 2.4.3 with Code::Blocks?

问题描述

我安装了代码:: Blocks with MinGW 和OpenCV 2.4.3。我想编译这个简单的程序：

  #include< opencv2 / highgui / highgui.hpp> 
 #include< iostream> 
 
 using namespace cv; 
 using namespace std; 
 
 int main（）
 {
 Mat im = imread（c：/path/to/lena.jpg）; 
 if（im.empty（））{
 cout<< 无法打开图像！ << endl; 
 return 1; 
} 
 imshow（Image，im）; 
 waitKey（0）; 
} 
  

如何正确设置CodeBlocks以编译上述代码？

我已在 c：\opencv 中安装OpenCV。

<要使用OpenCV与CodeBlocks，你需要告诉CodeBlocks：

1. 包含OpenCV头文件的目录→ c：\opencv\build\include


2. 链接&rarr所需的OpenCV库列表; c：\opencv\build\x86\mingw\libs\libopencv _ *。dll.a

---

1。添加OpenCV头文件目录

打开设置→ 编译器和调试程序... → 搜索目录标签→ 编译器标签

点击添加按钮添加新条目。在弹出对话框中，输入 c：\opencv\build\include ，

并点击确定。

---

2。添加链接所需的OpenCV库

打开设置 编译器和调试程序 ...→ 链接器设置标签。

点击添加添加新条目并打开弹出对话框。

点击...按钮打开文件打开对话框。转到 c：\opencv\build\x86 \mingw\lib 目录，然后按Ctrl-A选择所有文件。

>

点击打开添加文件，

点击确定以保存所有设置。 p>

现在你已经设置了include目录和链接库，你可以编译
并运行你的项目按F9键。

I've installed Code::Blocks with MinGW and OpenCV 2.4.3. I want to compile this simple program:

#include <opencv2/highgui/highgui.hpp>
#include <iostream>

using namespace cv;
using namespace std;

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

How to properly setup CodeBlocks for compiling the code above?

I have installed OpenCV in c:\opencv.

解决方案

To use OpenCV with CodeBlocks, you need to tell CodeBlocks:

1. The directory which contains the OpenCV header files → c:\opencv\build\include
2. List of OpenCV libraries needed for linking → c:\opencv\build\x86\mingw\libs\libopencv_*.dll.a

---

1. Add the OpenCV header files directory

Open Settings → Compiler and debugger... → Search directories tab → Compiler tab

Click add button for adding a new entry. In the popup dialog, type c:\opencv\build\include,

and click Ok.

---

2. Add the OpenCV libraries needed for linking

Open Settings → Compiler and debugger... → Linker settings tab.

Click add for adding new entries and open a popup dialog.

Click the "..." button to open the File Open Dialog. Go to c:\opencv\build\x86\mingw\lib directory and select all files by pressing Ctrl-A.

Click Open to add the files,

Click Ok to save all settings.

---

Now that you've set the include directory and the libraries for linking, you can compile and run your project by pressing F9 key.
