vscode debugging c program failed

问题:

执行调试时,出现问题:

无法在".vscode"文件夹(Cannot read property 'name' of undefined) 内创建"launch.json"文件 

解决方法:

一、创建文件夹

点击下图中红框处,创建文件夹,命名为“.vscode"

vscode debugging c program failed

二、创建launch.json

在.vscode文件夹中,创建launch.json文件,并将下面的代码复制进去,其中,miDubuggerPath后的路径为C++编辑器的安装路径

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "(gdb) Launch", // 配置名称,将会在启动配置的下拉菜单中显示
            "type": "cppdbg", // 配置类型,cppdbg对应cpptools提供的调试功能;可以认为此处只能是cppdbg
            "request": "launch", // 请求配置类型,可以为launch(启动)或attach(附加)
            "program": "${fileDirname}/${fileBasenameNoExtension}.exe", // 将要进行调试的程序的路径
            "args": [], // 程序调试时传递给程序的命令行参数,一般设为空即可
            "stopAtEntry": false, // 设为true时程序将暂停在程序入口处,相当于在main上打断点
            "cwd": "${workspaceFolder}", // 调试程序时的工作目录,此为工作区文件夹;改成${fileDirname}可变为文件所在目录
            "environment": [], // 环境变量
            "externalConsole": false, // 为true时使用单独的cmd窗口,与其它IDE一致;18年10月后设为false可调用VSC内置终端
            "internalConsoleOptions": "neverOpen", // 如果不设为neverOpen,调试时会跳到“调试控制台”选项卡,你应该不需要对gdb手动输命令吧?
            "MIMode": "gdb", // 指定连接的调试器,可以为gdb或lldb。但我没试过lldb
            "miDebuggerPath": "D:\\mingw64\\bin\\gdb.exe", // 调试器路径,Windows下后缀不能省略,Linux下则不要
            "setupCommands": [
                { // 模板自带,好像可以更好地显示STL容器的内容,具体作用自行Google
                    "description": "Enable pretty-printing for gdb",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": false
                }
            ],
            "preLaunchTask": "Compile" // 调试会话开始前执行的任务,一般为编译程序。与tasks.json的label相对应
        }
    ]
}
Copy after login

三、创建tasks.json

在.vscode文件中,新建tasks.json文件,编辑代码

{
    "version": "2.0.0",
    "tasks": [
        {
            "label": "Compile", // 任务名称,与launch.json的preLaunchTask相对应
            "command": "g++", // 要使用的编译器,C++用clang++;如果编译失败,改成gcc或g++试试,还有问题那就是你自己的代码有错误
            "args": [
                "${file}",
                "-o", // 指定输出文件名,不加该参数则默认输出a.exe,Linux下默认a.out
                "${fileDirname}/${fileBasenameNoExtension}.exe",
                "-g", // 生成和调试有关的信息
                "-Wall", // 开启额外警告
                "-static-libgcc", // 静态链接libgcc,一般都会加上
                "-std=c++11", // C++最新标准为c++17,或根据自己的需要进行修改
            ], // 编译命令参数
            "type": "process", // process是vsc把预定义变量和转义解析后直接全部传给command;shell相当于先打开shell再输入命令,所以args还会经过shell再解析一遍
            "group": {
                "kind": "build",
                "isDefault": true // 不为true时ctrl shift B就要手动选择了
            },
            "presentation": {
                "echo": true,
                "reveal": "always", // 执行任务时是否跳转到终端面板,可以为always,silent,never。具体参见VSC的文档
                "focus": false, // 设为true后可以使执行task时焦点聚集在终端,但对编译C/C++来说,设为true没有意义
                "panel": "shared" // 不同的文件的编译信息共享一个终端面板
            },
            // "problemMatcher":"$gcc" // 此选项可以捕捉编译时终端里的报错信息;本文用的是clang,开了可能会出现双重报错信息;只用cpptools可以考虑启用
        }
    ]
}
Copy after login

四、此时点击调试按钮,可以看到出现可以进行调试的选项
