VS Code C++ 开发调试环境配置

VS Code 项目的配置文件位于.vscode文件夹下。本文将具体说明在vscode中如何操作生成.vscode 文件夹下的三个配置文件：

(1). tasks.json (compiler build settings) ，负责编译

(2). launch.json (debugger settings)，负责调试

(3). c_cpp_properties.json (compiler path and IntelliSense settings)，负责更改路径等设置

首先安装C++拓展。点击在vscode界面最左侧的Extensions图标（打开快捷键：ctrl+shift+X），搜索“C/C++”，点击进行安装。

1、创建 tasks.json

告诉 VS Code 如何构建（编译）程序

{
    "version": "2.0.0",
    "tasks": [
        {
            "type": "cppbuild",
            "label": "C/C++: g++ build active file",
            "command": "/usr/bin/g++",
            "args": [
                "-g",
                "${file}",
                "-o",
                "${fileDirname}/${fileBasenameNoExtension}"
            ],
            "options": {
                "cwd": "${fileDirname}"
            },
            "problemMatcher": [
                "$gcc"
            ],
            "group": {
                "kind": "build",
                "isDefault": true
            },
            "detail": "compiler: /usr/bin/g++"
        }
    ]
}

2、创建launch.json

配置调试器。

{
    // 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": "g++ - Build and debug active file",
            "type": "cppdbg",
            "request": "launch",
            "program": "${fileDirname}/${fileBasenameNoExtension}",
            "args": [],
            "stopAtEntry": false,
            "cwd": "${fileDirname}",
            "environment": [],
            "externalConsole": false,
            "MIMode": "gdb",
            "setupCommands": [
                {
                    "description": "Enable pretty-printing for gdb",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": true
                }
            ],
            "preLaunchTask": "C/C++: g++ build active file",
            "miDebuggerPath": "/usr/bin/gdb"
        }
    ]
}

3、创建c_cpp_properties.json

更多地控制 C/C++ 扩展，它允许你更改设置，例如编译器的路径、包含路径、C++ 标准（默认为 C++17）

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

4、settings.json
