First, install vscode

I use the anaconda installation, you can refer vscode home page, there is mounting.

Second, install the C / C ++ plug-ins

Press Ctrl + shift + X, search for C / C ++ and install it. It will install the line.

Third, configure the debug and compile files

3.1 tasks.json file ---- generated out files

In order to facilitate compiling C ++ code VScode, we can similarly g ++ -g main.cpp etc. g ++ command to write VScode mission system.

Press ctrl + shift + p to open the command line, enter Tasks: Run task, Enter! ! ! Will appear the following prompt:

    No task to run found. configure tasks...

Then Enter,

    Create tasks.json file from template

Then select:

   Others Example to run an arbitrary external command.

Create default tasks.json file as follows:

{
    // See https://go.microsoft.com/fwlink/?LinkId=733558
    // for the documentation about the tasks.json format
    "version": "2.0.0",
    "tasks": [
        {
            "label": "build",
            "type": "shell",
            "command": "g++",
            "args": ["-g", "${file}", "-o", "${fileBasenameNoExtension}.out"]
        }
    ]
}

Here's label name for the task, we will "label" = "echo" was changed to "label" = "build".
Since our instruction is g ++, where the "command" = "echo Hello" was changed to "command" = "g ++" .
Then add g ++ arguments args. If our g ++ instructions: g ++ -g main.cpp, where you can set the parameter as follows:

3.2 launch.json file ---- executed out files

Select the folder / cpp file, press Ctrl + shift + D, click on the left side of the Debug button, select Add Configuration (Add configuration), and then choose C ++ (GDB / LLDB) Enter! ! Launch.json automatically generated file, modifications are as follows:

            "program": "enter program name, for example ${workspaceFolder}/a.out",

Changed

            "program": "${workspaceFolder}/${fileBasenameNoExtension}.out",

{

    "version": "0.2.0",
    "configurations": [
        {
            "name": "(gdb) Launch",
            "type": "cppdbg",
            "request": "launch",
            "program": "${workspaceFolder}/${fileBasenameNoExtension}.out",
            "args": [],
            "stopAtEntry": false,
            "cwd": "${workspaceFolder}",
            "environment": [],
            "externalConsole": true,
            "MIMode": "gdb",
            "preLaunchTask":"build",   
            "setupCommands": [
                {
                    "description": "Enable pretty-printing for gdb",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": true
                }
            ]
        }
    ]
}

"PreLaunchTask": "build", this parameter must be, otherwise it will error, when debug, saying lauch: file.out file does not exist.

Five OPENCV build environment

5.1 configuration opencv

Go here https://github.com/opencv/opencv/releases download, tar.tg file. Pressure.

cd opencv/cmake 
cmake ..
suido make
sudo make install

5.2 Configuration vscode environment

5.2.1 c_cpp_properties.json

Press ctrl + shift + p, input edit, select the C / C ++: edit configuration ( json), will pop c_cpp_properties.json. He is the configuration of the external environment.

{
    "configurations": [
        {
            "name": "Linux",
            "includePath": [
                "${workspaceFolder}/**"
            ],
            "defines": [],
            "compilerPath": "/usr/bin/gcc",
            "cStandard": "c11",
            "cppStandard": "c++17",
            "intelliSenseMode": "clang-x64"
        }
    ],
    "version": 4
}

修改它
"includePath": [
                "${workspaceFolder}/**",
                "/usr/local/include", //请确保你的opencv opencv2头文件夹安装在这个目录

5.2.2 task.josn

tasks.json里面修改的是参数问题，我还没试试那个好使

"args": [
                "-g",
                "${workspaceRoot}/test.cpp",
                "-L", "/usr/local/opencv3.4/lib/lib*",
                "-o",
                "run"
                
            ],

"args": [
        "-g", "-std=c++11", "${file}", "-o", "${fileBasenameNoExtension}.o",// 设置动态链接库
        "-I", "/usr/local/include",
        "-I", "/usr/local/include/opencv",
        "-I", "/usr/local/include/opencv2",
        "-L", "/usr/local/lib",
        "-l", "opencv_core",
        "-l", "opencv_imgproc",
        "-l", "opencv_imgcodecs",
        "-l", "opencv_video",
        "-l", "opencv_ml",

        "-l", "opencv_imgcodecs",
        "-l", "opencv_photo",
        "-l", "opencv_videoio"
    ],// 编译命令参数

5.2.3  libjasper.so.1

Lack libjasper.so.1 , so what way, installation chant.
Command is as follows:

sudo add-apt-repository "deb http://security.ubuntu.com/ubuntu xenial-security main"
sudo apt update
sudo apt install libjasper1 libjasper-dev
