Я х-компилирую голый C ++ для ARM Cortex_M7 с помощью набора инструментов arm-none-eabi-gcc / g ++, и он отлично работает, высвечивая красивую прошивку на моей плате.
Теперь, когда / если яхочу включить в "старые добрые" файлы C ++ <mutex>, <queue>, <iostream>..., я получаю водопад ошибок компиляции (я не буду беспокоиться о вставке здесь, поскольку я знаю , они не имеют отношения ..)
Ожидается ли это, потому что они просто не доступны, и я должен действовать как человек и сам написать свою очередь, мьютекс, ... классы, как я делаю прямо сейчас (звучит немного как изобретение колесахотя) или мне не хватает "sysroot"? Но ... Есть ли такая вещь для каждой отдельной архитектуры ARM-Cortex_Mx в мире?
Я, вероятно, запутался, читая this , между sysroot, std, linux и, возможно, мне нужнозагрузить соответствующую цепочку ссылок (arm-none-linux-gnueabi-g ++?), содержащую определенный 'sysroot' (со всеми включениями и библиотеками для моей цели), потому что я компилирую в среде Linux, хотямоя цель не работает на Linux (голый металл)?
Боюсь, я не могу найти нужную тему в Google (или неправильно погуглил?)
Спасибо за разъяснения!

Так что чувство зарезервированного имени printf (), загружаемого из библиотек / драйверов ATMEL / Microchip, отравляет использование std.
