Когда я использую llvm-gcc-4.2 в Xcode4.6.3 для компиляции источников «x265», он сообщил о странной ошибке: ./source/encoder/reference.h: 38: ошибка: вперед декларация «класса x265 :: MotionReference'.However, класс декларации x265 :: MotionReference завершена в reference.h:Сообщение об ошибке прямого объявления об ошибке, сообщенное llvm-gcc-4.2
