Я уже некоторое время пытаюсь заставить OpenCV работать на Xamarin.iOS с arm64. Последняя версия, которую я могу найти на opencv.org, кажется, не построена для arm64. Мне не удалось создать самые последние библиотеки, но получил сборку для OpenCV 2.4.12 (https://github.com/Itseez/opencv/tree/2.4.12). Тем не менее, когда я добавить библиотеку к моему решению (с помощью связывания библиотеки), я получаю следующее сообщение об ошибке:Использование OpenCV в Xamarin.iOS (arm64)

Я прочитал на https://github.com/twelve17/openalpr-ios/issues/5, что мне нужно сделать ссылку на libjpeg. Я делаю это с помощью следующей команды mtouch: -gcc_flags "-L${ProjectDir} -ljpeg -force_load ${ProjectDir}/libjpeg.a" Теперь, однако, я получаю ошибку, которая дублирует доступны:

Я понятия не имею, как решить эту проблему, и где я собираюсь неправильно. Может кто-нибудь мне помочь?
Я не уверен, но если я помню, вам не нужен флаг '-ljpeg', а также' $ {ProjectDir}/libjpeg.a'. (Но я не уверен, это было время, так как я собрал opencv для ios.) –
Спасибо за ваш комментарий. Это дало мне ощущение, что я сделал что-то неправильно со встроенным и разрешил мне найти обходной путь. –
Рад видеть, что вы работали, и хорошая работа, отвечающая на ваш собственный вопрос, так что будущие пользователи могут извлечь выгоду! :) –
