Мне нужно собрать OpenBLAS библиотеку iOS. Я решил построить 0.3.6 версию этого. Я считаю, что это самая последняя стабильная версия библиотеки.
Вы можете найти выпуски этой библиотеки здесь - https://github.com/xianyi/OpenBLAS/releases
Я столкнулся со следующей проблемой - похоже, компилятор ассемблера предоставлен clang, который можно найти в XCode, кажется, не понимает определенный синтаксис в .S файлах, предоставляемых библиотекой.
У меня есть два файла (nrm2.S и znrm2.S), которые вызывают все мои проблемы,Вот nrm2.S. Я не буду предоставлять другой файл, потому что ошибки там точно так же. Но если вы захотите взглянуть и на него, я опубликую его, просто дайте мне знать:

KERNEL_F1
Пока я искал объяснение проблемы, я нашел эту ссылку - https://www.avrfreaks.net/forum/labels-inside-macros. Это дало мне понимание того, что проблемный символ \@ является своего рода счетчиком меток, который решает проблему уникальных имен меток внутри макроса GAS.
К сожалению, я почти ничего не знаю о Ассемблере и не могу дать исправленияна это самостоятельно. Поэтому я подумал, что, может быть, здесь есть ассистенты-гуру, которые готовы провести меня через этот «темный лес».
Есть ли шанс, что \@ является относительно новым символом, и компилятор Apple не знает об этомвсе же? Что я должен сделать, чтобы решить эту проблему?
Заранее спасибо!
