vscode中配置C/C++调试环境(launch.json和tasks.json)
作者:互联网
launch.json和tasks.json
launch.json
launch.json中存放运行或者调试可执行文件时的配置:
{
// 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++.exe build and debug active file",
"type": "cppdbg",
"request": "launch",
"program": "${fileDirname}\\${fileBasenameNoExtension}",
"args": [],
"stopAtEntry": false,
"cwd": "${workspaceFolder}",
"environment": [],
"externalConsole": false,
"MIMode": "gdb",
"miDebuggerPath": "/usr/bin/gdb",
"setupCommands": [
{
"description": "为 gdb 启用整齐打印",
"text": "-enable-pretty-printing",
"ignoreFailures": true
}
],
"preLaunchTask": "g++.exe build active file"
}
]
}
首先使用cmake和make生成可调试的可执行文件,在launch.json中的program字段设置可执行文件所在位置,如设置program为:
"program": "${workspaceFolder}/build/my_cmake_exe"
// ${workspaceFolder}/build/my_cmake_exe代表在当前目录下的build文件夹中的可执行文件my_cmake_exe,是一个绝对路径。
配置好launch.json文件,我们就可以通过vscode的调试菜单对可执行文件进行调试了。
tasks.json
tasks.json中存放生成可执行文件的命令:
{
"version": "2.0.0",
"options": {
"cwd": "${workspaceFolder}/build" // 进入本项目目录下的build文件夹下
},
"tasks": [
{
"type": "shell",
"label": "cmake", // 名字
"command": "cmake", // 执行cmake命令,参数为..
"args": [
".."
]
},
{
"label": "make",
"group": { // 不知道有什么用?
"kind": "build",
"isDefault": true
},
"command": "make",
"args": [
]
},
{
"label": "Build",
"dependsOrder": "sequence", // 按列出的顺序执行任务依赖项
"dependsOn":[
"cmake",
"make"
]
}
]
}
在tasks.json中建立了三个任务,分别为Build、cmake和make,其中Build依赖cmake和make。Build任务的含义为:使用cmake和make生成可执行文件。
我们可以将launch.json中的preLaunchTask设置为"preLaunchTask": "Build",那么在使用launch.json进行调试前,会先执行Build的任务。
launch.json和tasks.json的其他字段??
