C++ 如何添加g++；从MinGW到PATH

我在Windows 10上使用Visual Studio代码，并尝试使用MinGW的g++构建一个程序（从源文件Bus.cpp名为Bus）。我使用从以前的线程中读取的各种方法修改了tasks.json文件。我提供了tasks.json文件的屏幕截图以及构建后的结果（ctrl+shift+b）。我也在下面提供我的问题

问题1）我希望能够使用方法1构建和创建一个名为“总线”的程序。然而，我必须用MinGW的g++编译器的目录路径替换“g++”（如方法2所示）。我要怎么做才能把“g++”放在MinGW的g++.exe的路径上

问题2）它看起来像是使用方法2和4编译的，这两种方法为MinGW的g++编译器提供了目录路径，但我没有看到名为“bus”的编译程序，即使我在命令中使用了“-o bus”。为什么我看不到呢

编辑以显示代码：

第一个方法tasks.json文件：

{
    // See https://go.microsoft.com/fwlink/?LinkId=733558
    // for the documentation about the tasks.json format
    "version": "2.0.0",
    "tasks": [
        {
            "label": "build",
            "type": "shell",
            "command": "g++ -g bus.cpp -o bus",
            "group": {
                "kind": "build",
                "isDefault": true
            }
        }
    ]
}

{
    // See https://go.microsoft.com/fwlink/?LinkId=733558
    // for the documentation about the tasks.json format
    "version": "2.0.0",
    "tasks": [
        {
            "label": "build",
            "type": "shell",
            "command": "C:/MinGW/bin/g++.exe -g bus.cpp -o bus",
            "group": {
                "kind": "build",
                "isDefault": true
            }
        }
    ]
}

{
    // See https://go.microsoft.com/fwlink/?LinkId=733558
    // for the documentation about the tasks.json format
    "version": "2.0.0",
    "tasks": [
        {
            "label": "build",
            "type": "shell",
            "command": "C:/MinGW/bin/g++",
            "args": [
                "-g", "bus.cpp", "-o", "bus"
            ],
            "group": {
                "kind": "build",
                "isDefault": true
            }
        }
    ]
}

总而言之，您需要将

mingW gcc

添加到您的路径中

最简单的方法：

开始菜单->计算机->右键单击->属性->高级系统设置（左侧）->环境变量

---

在末尾添加分号后，将目录添加到

路径

变量。
