vscode c++开发环境问题整理

整体参考官网文章

https://code.visualstudio.com/docs/cpp/config-mingw

上述常见问题整理如下：

1. 在线的mingw-w64-install.exe安装失败，可以采用离线安装，离线安装包说明如下
   https://sourceforge.net/projects/mingw-w64/files/

• 选择一个离线包下载就可以，见下图
• 下载解压到磁盘中后，需要在path添加路径，见下图
  
  

2. 在一个文件夹中打开工程，这样后续生成的tasks.json和launch.json都是正确的，简单做法就是在对应工程-右键-vscode打开
   
3. tasks.json和launch.json的配置，可以参考如下设置

//tasks.json
{
    // See https://go.microsoft.com/fwlink/?LinkId=733558 
    // for the documentation about the tasks.json format

            "args": [
                "-g",
                "${file}",
                "-o",
                "${fileDirname}\\${fileBasenameNoExtension}.exe"
            ],
            "options": {
                "cwd": "C:\\mingw64\\bin"
            },

                "$gcc"

                "isDefault": true
            }
        }
    ]
}
//launch.json
