Win10 VS Code 项目开发opencv C++ 初学踩坑

VS Code环境中的C/C++ && OpenCV开发

背景：
用VS打开《计算机视觉算法 -基于OpenCV的计算机应用开发》附带C/C++源文件时，会对头文件进行内容提示：大意是无法找到头文件：includePath。
#include // 标准C++头文件
#include <opencv2/opencv.hpp> //OpenCV头文件

安装VScode搭配c/c++环境出现“#include errors detected. Please update your includePath…”问题的解决

解决上述问题方法：

1. 安装C/C++工具包，配置VS Code；可以参考网页：添加链接描述
   这里面有很多需要添加的扩展，对于编辑十分方便。其主要目的是可以在工程目录中建立“.vscode/c_cpp_properties.json”然后对相关内容进行补充。
   特别说明，不需要在C/C++ intelligence (大概名字吧)的配置采用WinGW作为编译器，联网后VS自动扫描VS studio。
2. 创建并建立相关文件，参考添加链接描述
   task.json, launch.json, c_cpp_properties.json，这三个文件都需要存在。
3. 实例

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

using namespace std;
using namespace cv;

int main()
{
    cout << cv::getBuildInformation();
    return 0;
}

4. task.json文件

{
    "version": "2.0.0",
 
    "presentation": {
        "reveal": "always",
        "panel": "new",
        "echo": true
    },
 
    "options": {
        "env": {
            "LINUX_SRC_HOME": "/home/user/system/packages/services/Car/evs",
            "LOCAL_SRC_HOME": "${workspaceRoot}"
        }
    },
    "type": "shell",
    "problemMatcher": {
        "owner": "cpp",
        "fileLocation": [
            "relative",
            "${workspaceRoot}"
        ],
        "pattern": {
            "regexp": ".*(app/.*|project/.*):(\\d+):(\\d+):\\s+(warning|error):\\s+(.*)$",
            "file": 1,
            "line": 2,
            "column": 3,
            "severity": 4,
            "message": 5
        }
    },
 
    "tasks": [
        {
            "label": "g++",
            "type":  "shell",
            "command": "g++",
            "args": ["-g",  "${file}",  "-o",  "${file}.o",
                "-I","D:/opencv/build/include",
                "-I","D:/opencv/build/include/opencv2",
                "-L", "D:/opencv/build/x64/v15/lib",
                "-l", "opencv_world411d"
            ],
            "identifier": "CodeSync",
            "taskClassify": "同步代码"
        }
    ]
}

6. launch.json 文件

{
    // Use IntelliSense to learn about possible attributes.
    // Hover to view descriptions of existing attributes.
    // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
    "version": "0.2.0",
    "configurations": [
        {
            "name": "(Windows) 启动",
            "type": "cppvsdbg",
            "request": "launch",
            "program": "输入程序名称，例如 ${workspaceFolder}/a.exe",
            "args": [],
            "stopAtEntry": false,
            "cwd": "${workspaceFolder}",
            "environment": [],
            "externalConsole": true
        }
    ]
}

8. c_cpp_properties.json文件

{
    "configurations": [
        {
            "name": "Win32",
            "includePath": [
                "${workspaceFolder}/**",
                "D:/opencv/build/include",
                "D:/opencv/build/include/opencv2",
                "D:/opencv/build/x64/vc15/lib"       // 采用WinPack 安装OpenCV 4.1 在D:盘目录下
            ],
            "defines": [
                "_DEBUG",
                "UNICODE",
                "_UNICODE"
            ],
            "intelliSenseMode": "${default}"
        }
    ],
    "version": 4
}

希望以上内容对初学者有所帮助。交流意见
