arm-none-eabi-gcc/g++ ツールチェーンを使用して ARM Cortex_M7 用のベアメタル C++ を x コンパイルしていますが、正常に動作し、ボード上で適切なファームウェアがフラッシュされます。
現在、「古き良き」C++ ファイルにインクルードしたい場合は、コンパイル エラーのウォーターフォールが発生します (これらは関係ないことがわかっ<mutex>, <queue>, <iostream>...ているので、ここに貼り付けることはしません..)
これらは単に利用できないため、これは予想されることであり、私が今行っているように、人間として行動し、独自のキュー、ミューテックス、... クラスを自分で作成する必要があります (車輪の再発明のように聞こえますが)、それとも私ですか? 「sysroot」がありませんか？しかし...世界中のすべてのARM-Cortex_Mxアーキテクチャにそのようなものはありますか?
私はおそらくこれを読んで、sysroot、std、linuxの間で混乱しており、特定の「sysroot」を含む適切なtoochain（arm-none-linux-gnueabi-g ++？）をダウンロードする必要があるかもしれません（私のすべてのインクルードとライブラリを含む）ターゲット)は、ターゲットが Linux (ベアメタル) で実行されないにもかかわらず、Linux 環境内でコンパイルしているためですか?
残念ながら、適切な件名をググることができません (または、ググを間違えましたか?)
説明ありがとうございます！

したがって、ATMEL/Microchip のライブラリ/ドライバからの "printf()" 予約名 ovlerloading の感覚は、標準インクルードの使用を害しています。
