@[刘洢含](/user/176843) 下载完还是让你选择环境

@[wzmzmhk](/user/250983) 你bdfs一下？

先下载mingw并添加到系统环境变量path
工作目录下创建.vscode文件夹
以下4个文件放到.vscode文件夹下：
##### launch.json
```
// https://code.visualstudio.com/docs/cpp/launch-json-reference
{
"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，对于C/C++可认为此处只能是cppdbg，由cpptools提供；不同编程语言不同
"request": "launch", // 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
"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": "${fileDirname}", // 调试程序时的工作目录，此为工作区文件夹；改成${fileDirname}可变为文件所在目录
"environment": [], // 环境变量
"externalConsole": true, // 使用单独的cmd窗口，与其它IDE一致；为false时使用内置终端
"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": "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" // 调试前执行的任务，一般为编译程序。与tasks.json的label相对应
}]
}
```
##### tasks.json
```
// https://code.visualstudio.com/docs/editor/tasks
{
"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gcc
"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
"-m64", // 不知为何有时会生成16位程序而无法运行，此条可强制生成64位的
"-Wall", // 开启额外警告
"-static-libgcc", // 静态链接libgcc，一般都会加上
"-fexec-charset=GBK", // 生成的程序使用GBK编码，不加这条会导致Win下输出中文乱码；繁体系统改成BIG5
"-D__USE_MINGW_ANSI_STDIO", // 用MinGW写C时留着，否则不需要，用于支持printf的%zd和%Lf等
], // 编译的命令，其实相当于VSC帮你在终端中输了这些东西
"type": "process", // process是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，即使设为never，手动点进去还是可以看到
"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" // 捕捉编译时终端里的报错信息到问题面板中，修改代码后需要重新编译才会再次触发
// 本来有Lint，再开problemMatcher就有双重报错，但MinGW的Lint效果实在太差了；用Clangd可以注释掉
}]
}
```

注意**c_cpp_properties.json**中"**compile path**"一项后改成自己编译器的绝对路径

@[Untitled0](/user/393767) 好的，来试试
by wzmzmhk @ 2021-09-21 20:00:38
@[wzmzmhk](/user/250983) 首先一定要安编译器啊，系统有环境才能运行
by Untitled0 @ 2021-09-21 20:25:49
@[Untitled0](/user/393767) 有的，现在还在下载，它上面显示还有50多分钟，但是一共就47个MB
by wzmzmhk @ 2021-09-21 20:34:56
@[Untitled0](/user/393767) 现在不保存在桌面上可以变异了，但是编译总显示：
还是按照原计划进行吗？
by wzmzmhk @ 2021-09-21 20:41:13
@[wzmzmhk](/user/250983) 你安装的是什么编译器？
