arm-none-eabi-gcc的任务配置

Question

我正在寻找帮助，以正确配置task.json文件，以构建C/C++项目与arm-none-eabi-gcc编译器。

我可以从命令行将C项目编译为arm-none-eabi-gcc -specs=nosys.specs hello_c.c -o hello_c.out .

但是在vscode下使用vscode进行配置

"version": "2.0.0",
    "tasks": [
        {
            "type": "cppbuild",
            "label": "arm-none-eabi-gcc build active file",
            "command": "c:\\Program Files (x86)\\GNU Arm Embedded Toolchain\\9 2020-q2-update\\bin\\arm-none-eabi-gcc.exe",
            "args": [
                "-specs=nosys.specs",
                "${file}",
                "-o",
                "${fileDirname}\\${fileBasenameNoExtension}.bin"
            ],
            "options": {
                "cwd": "c:\\Program Files (x86)\\GNU Arm Embedded Toolchain\\9 2020-q2-update\\bin"
            },
            "problemMatcher": [
                "$gcc"
            ],
            "group": {
                "kind": "build",
                "isDefault": true
            },
            "detail": "compiler: c:\\Program Files (x86)\\GNU Arm Embedded Toolchain\\9 2020-q2-update\\bin\\arm-none-eabi-gcc.exe"
        }
    ]
}

it输出

在我的例子中，我已经将"type“更改为"shell”，它起了作用。就像这里的示例任务一样：https://code.visualstudio.com/docs/cpp/config-clang-mac。它看起来像"cppbuild“类型目前已经损坏，或者我们不知道如何正确地使用它。
