У меня 4 предупреждения, которые компилятор не идентифицирует: ссылка
Когда я вхожу в библиотеку Arm-Math, появляются все эти ошибки: ссылка 2
Почему компилятор их не распознает? И главный вопрос, как я могу исправить эти ошибки? Arm-Math - официальная библиотека, она не должна создавать проблем ... Это мой код:
