Step 1: 安裝MinGW

下載MinGW-w64

MinGW-w64

 

開始安裝

 

設定環境變數

 

測試

打開cmd，執行指令：g++ --version

 

Step 2: 編譯OpenCV

建立資料夾

 

開始編譯

勾選： 

BUILD_opencv_world 

WITH_OPENGL  

取消勾選： 

OPENCV_ENABLE_ALLOCATOR_STATS

打開cmd，執行指令：mingw32-make -j4

執行指令：mingw32-make install

 

設定環境變數

 

Step 3: VSCode環境設定

安裝C/C++ Extension

 

新增c_cpp_properties.json

 

按下Ctrl+Shift+P後，選擇Edit Configurations

{
    "configurations": [
        {
            "name": "Win32",
            "includePath": [
                "${workspaceFolder}/**",
                "C:\\opencv\\build\\x64\\MinGW\\install\\include",
                "C:\\opencv\\build\\x64\\MinGW\\install\\include\\opencv",
                "C:\\opencv\\build\\x64\\MinGW\\install\\include\\opencv2"
            ],
            "defines": [
                "_DEBUG",
                "UNICODE",

            "intelliSenseMode": "windows-gcc-x64"
        }
    ],
    "version": 4
}

 

新增launch.json

 

按下Ctrl+Shift+D後，選擇create a launch.json file

 

選擇C++(GDB/LLDB)

 

選擇g++.exe

 

忽略Error，編輯launch.json

            ],
            "preLaunchTask": "C/C++: g++.exe 建置使用中檔案"
        }
    ]
}

 

新增tasks.json

{
    "tasks": [
        {
            "type": "cppbuild",
            "label": "C/C++: g++.exe 建置使用中檔案",

            "args": [
                "-g",
                "${file}",
                "-o",
                "${fileDirname}\\${fileBasenameNoExtension}.exe",
                "-I", "C:\\opencv\\build\\x64\\MinGW\\install\\include",

                "isDefault": true
            },
            "detail": "偵錯工具產生的工作。"
        }
    ],
    "version": "2.0.0"
}

 

測試

#include <opencv2/imgcodecs.hpp>
#include <opencv2/imgproc.hpp>
#include <opencv2/highgui.hpp>
using namespace cv;
int main()
{
    Mat img = imread("flower.jpg");
    resize(img, img, Size(0, 0), 0.1, 0.1);
    imshow("test", img);
    waitKey();
    destroyAllWindows();
    system("PAUSE");
    return 0;
}

按下F5，開始Debug 

完成!!!
