这个是什么错误呀啊````
bits/stl_algobase.h这个文件是mingw自己自带的,为什么还出现编译错误呢?
#include <iostream>
using namespace std;

int main()
cout << "Hello world!!!" << endl; // prints !!!Hello World!!!
return 0;

源码就这个刚配置的环境Eclipse+mingw

表示你这个编译环境有问题，那段代码没什么大问题，环境没配置好 参考技术A 说的是第9行，你贴的这个一共7行，怎么知道什么问题？
大多数是类型信息不完整引起的，少数编译器配置有问题。
from ..\src\learn_1.cpp:9: 参考技术B 我是来打酱油的，表里我。。。

使用Windows 10和MINGW编译器在VS Code上使用gdb调试器调试时出错

我正在遵循https://code.visualstudio.com/docs/cpp/config-mingw上的文档以在VS代码上设置我的C ++开发环境。

我成功创建了构建任务并运行了构建任务，但是当我尝试设置调试器（GDB调试器）时，在终端上得到了以下输出。

C:UsersAyonc++helloworld> cmd /C "c:UsersAyon.vscodeextensionsms-vscode.cpptools-0.28.1debugAdaptersinWindowsDebugLauncher.exe --stdin=Microsoft-MIEngine-In-shlwrnf5.x12 --stdout=Microsoft-MIEngine-Out-vg12hskh.c52 --stderr=Microsoft-MIEngine-Error-nrcvh0zz.0u0 --pid=Microsoft-MIEngine-Pid-m1nmxyvs.qk2 --dbgExe=C:MinGWingdb.exe --interpreter=mi "
'cmd' is not recognized as an internal or external command,
operable program or batch file.

我对输出中的“ cmd /”如何产生感到好奇。请帮助我解决此错误。

提前感谢。

供参考，这是我的launch.json

答案

您是否将mingw64 / bin添加到系统路径？方法如下：

Control panel -> Edit path -> Environment variables -> Path -> New

您也可以在vscode官方网站。
