使用Vscode 开发调试 C/C++ 项目

需要安装的扩展 C/C++

如果是远程 Linux上开发还需要安装 Remote Development

创建工作目录后,代码远程克隆... 省略..
创建项目配置文件,主要的作用是代码智能提示,错误分析等等...
按F1,输入 C/C++ 选择编辑配置UI或者json 这个操作会生成 .vscode/c_cpp_properties.json 配置文件

修改相关的参数,如头文件路径,预定义参数,编译器等

{
    "configurations": [
        {
            "name": "Linux",
            "includePath": [
                "${workspaceFolder}/**" // 包含了当前工作下所有头文件,如果没有在该目录下需要引入
            ],
            "defines": [ // 这里是项目中需要的预定义 LINUX环境通常需要加LINUX
                "LINUX",
                "ACI_TEST"
            ],
            "compilerPath": "/usr/bin/g++", // 编译器程序
            "cStandard": "gnu99",
            "cppStandard": "gnu++14",
            "intelliSenseMode": "linux-gcc-x64"
        }
    ],
    "version": 4
}

(注意) 这个配置文件与编译和执行没有任何关系,它仅仅用于代码提示和错误提示

代码编译和调试配置
选中打开一个.c 或者 .cpp 文件,按F5 选择环境和编译器

生成了2个文件

.vscode/launch.json

{
    // 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

    "configurations": [
        {

            "request": "launch",
            "program": "${fileDirname}/${fileBasenameNoExtension}", // 需要调试的程序路径,如 ${workspaceFolder}/test
            "args": [], // 调试程序需要接收的参数,如 test -c =>  "args": ["-c"]
            "stopAtEntry": false,
            "cwd": "${workspaceFolder}",
            "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", // 在调试之前需要做什么, 就是当你按下f5, 首先会去不如编译程序... make 或者 gcc ,g++ 编译上面路径的程序,
                                                             // "C/C++: g++ build active file" 只是一个名称,它会去 tasks.json 中找这个名称, 执行 这个任务之后开始调试
            "miDebuggerPath": "/usr/bin/gdb", // 调试的gdb ,要确保环境已经安装了gdb, sudo apt install gdb
            "envFile": "${workspaceFolder}/.env" // 配置环境变量的文件路径,下面会继续说明用处.
        }
    ]
}

.vscode/tasks.json

{
    "tasks": [
        {
            "type": "cppbuild", // shell 类型...
            "label": "C/C++: g++ build active file", // preLaunchTask 的名称
            "command": "/usr/bin/g++", // 编译器
            "args": [
                "-g",
                "${file}",
                "-o",
                "${fileDirname}/${fileBasenameNoExtension}"
            ],
            "options": {
                "cwd": "${workspaceFolder}"
            },
            "problemMatcher": [
                "$gcc"
            ],
            "group": {
                "kind": "build",
                "isDefault": true
            },
            "detail": "Task generated by Debugger."
        }
    ],
    "version": "2.0.0"
}

这个文件就是怎么去编译你的程序,没什么可说 , make 或者 gcc g++ 编译
贴一个我的项目 tasks 用make 编译

{
    "tasks": [
        {
            "type": "shell",
            "label": "make_1",
            "command":"make -j6 -f makefile_local.mk 2>build_error.log",
            "options": {
                "cwd": "${workspaceFolder}/UnitTesting/"
            },
            "problemMatcher": []
        },
        {
            "type": "shell",
            "label": "make_2",
            "command":"make -j6 -f makefile_local.mk 2>build_error.log",
            "options": {
                "cwd": "${workspaceFolder}/"
            },
            "problemMatcher": []
        },
        {
            "type": "shell",
            "label": "build",
            "dependsOrder": "sequence",
            "dependsOn": [
                "make_2",
                "make_1"
            ],
            "options": {
                "cwd": "${workspaceFolder}"
            },
            "problemMatcher": []
        }
    ],
    "version": "2.0.0"
}
