linux下vscode环境配置

编译器，调试器安装

sudo apt update

#通过以下命令安装编译器和调试器

sudo apt install build-essential gdb

#安装成功确认

gcc --version

g++ --version

gdb --version

Cmake安装

#安装

sudo apt install cmake

#查看

cmake --version

vscode中插件安装

c/c++

CMake

CMake Tools

vscode文件配置

launch.json

在配置这个文件夹的时候只需要关注两个地方，一个是配置可执行文件的绝对路径，另一个是指定在执行launch.json前, 需要执行的编译指令。如下：

run(F5)-> c++(GDB/LLDB)->g+±生成和调试活动文件，按次序点击后会生成launch.json文件

program:可执行文件的绝对路径，如：“program”:"${workspaceFolder}/build/${fileBasenameNoExtension}"

prelauchTask: 在执行调试前，需要执行tasks.json中label为Build的指令编译可执行文件 如：“preLaunchTask”: “Build”

修改后的launch.json,如下：

{

// 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

//program:可执行文件的绝对路径

//prelauchTask:在执行调试前，需要执行task.json中label为Build的指令编译可执行文件

"version": "0.2.0",

"configurations": [

{

"name": "g++ - 生成和调试活动文件",

"type": "cppdbg",

"request": "launch",

"program": "${workspaceFolder}/build/${fileBasenameNoExtension}",

"args": [],

"stopAtEntry": false,

"cwd": "${workspaceFolder}",

"environment": [],

"externalConsole": false,

"MIMode": "gdb",

"setupCommands": [

{

"description": "为 gdb 启用整齐打印",

"text": "-enable-pretty-printing",

"ignoreFailures": true

}

],

"preLaunchTask": "Build",

"miDebuggerPath": "/usr/bin/gdb"

}

]

}

tasks.json

这个文件的任务主要是告诉vscode如何去编译程序，在按下F5的时候先执行这个文件以生成可执行文件，并提供给launch.json调试。那如何在配合cmake的情况下配置编译指令呢？

Terminal->Configure Default Build Task…->c/c++:g++ build active file, 按次序点击后会自动生成tasks.json

指定编译生成文件的存放路径"${workspaceFolder}/build" 。注意：在配置cmake指令时需要提供CMakeLists.txt文件的绝对路径。

"options": {

"cwd": "${workspaceFolder}/build"

},

配置cmake …(这里CMakeLists.txt在build的上层目录)

{

"type": "shell",

"label": "cmake",

"command": "cmake",

"args": [".."]

},

配置 make 命令 。

{

"label": "make",

"group": {

"kind": "build",

"isDefault": true

},

"command": "make",

"args": []

},

在一个便签中汇总配置好的命令，并依次执行

{

"label": "Build",

"dependsOrder": "sequence", // 按照列出的顺序执行任务依赖项

"dependsOn": [

"cmake",

"make"

]

}

整合后得到的tasks.json，如下：

{

"version": "2.0.0",

"options": {

"cwd": "${workspaceFolder}/build"

},

"tasks": [

{

"type": "shell",

"label": "cmake",

"command": "cmake",

"args": [

".."

]

},

{

"label": "make",

"group": {

"kind": "build",

"isDefault": true

},

"command": "make",

"args": []

},

{

"label": "Build",

"dependsOrder": "sequence", // 按照列出的顺序执行任务依赖项

"dependsOn": [

"cmake",

"make"

]

}

]

}
