Question

我正在按照此tutorial在Windows pc上设置vs代码。

我通过从其他文件夹调用g ++来检查路径是否正确。

但是我仍然在与代码有关的错误：

Cannot find "C:\mingw-w64\i686-8.1.0-posix-dwarf-rt_v6-rev0\mingw64\bin\g++.exe".

试图从g++ helloworld.cpp所在的文件夹使用命令提示符运行helloworld.cpp不会给出错误或输出。

有人可以告诉我我错过了什么吗？

编辑：

该代码实际上已经被编译。它产生一个a.exe，并且运行良好。问题是我需要将其集成到vs代码中。我猜它类似于this，但我不确定。

Answer 1

您确定路径正确吗？通常，如果它说找不到文件，那是因为文件不存在。

当我安装MinGW-W64时，它转到C：（...）\ mingw-w64 \ i686-8.1.0-posix-dwarf-rt_v6-rev0 \ mingw32。因此，我认为您的路径是错误的（如消息所示）（除非您手动更改）：它不应位于mingw64 \ bin中，而应位于mingw32 \ bin中。

Answer 2

在tasks.json中，您拥有

"tasks": [
    {
        ...
        "command": "g++",
        ...
        "options": {
            "cwd": "C:/mingw-w64/i686-8.1.0-posix-dwarf-rt_v6-rev0/mingw64/bin/"
        },
        ...

但是您应该使用当前的工作目录

"cwd": "${workspaceFolder}"

有效吗？我认为您的task.json应该是：

    {
        // See https://go.microsoft.com/fwlink/?LinkId=733558 
        // for the documentation about the tasks.json format
        "version": "2.0.0",
        "tasks": [
            {
                "type": "shell",
                "label": "g++.exe build active file",
                "command": "g++",
                "args": [
                    "-g",
                    "helloworld.cpp",
                    "-o",
                    "helloworld"
                ],
                "options": {
                    "cwd": "${workspaceFolder}"
                },
                "problemMatcher": [
                    "$gcc"
                ],
                "group": {
                    "kind": "build",
                    "isDefault": true
                }
            }
        ]
    }

关键部分是添加正确的cwd选项。在此配置中，“ helloworld”应位于您的工作区文件夹下。如果不是这种情况，请相应地更新helloworld.cpp的路径。
