Это то, что я действительно никогда не видел, но я загрузил исходный код примера синусоидальной волны в http://www.audiosynth.com/sinewavedemo.html.11415 ошибки компиляции FTW?

Он находится в старом проекте Project Builder Project, и я хочу скомпилировать его с помощью Xcode (GCC). Однако Xcode дает мне 11415 ошибок компиляции. Первые немногие из них (все в прекомпиляция из AppKit.h):

Может ли кто-нибудь помочь мне скомпилировать этот пример? Я бы это сделал. Спасибо

Прежде чем спросить, да, я могу скомпилировать любое приложение AppKit. – 2010-06-11 17:55:39

Не могли бы вы опубликовать несколько строк кода? – Beta

Моя первая догадка заключается в том, что ваш пользователь каким-то образом заканчивается, включая заголовки Objective-C при компиляции кода C. (NSObject.h должен быть включен только в файлы .m). Или установите ваши файлы .c, которые должны быть скомпилированы как Objective-C, или убедитесь, что ваш файл заголовка префикса не содержит заголовки объектов Objective-C.

Если это относительно старый пример кода, вам может быть лучше переключиться на gcc 4.0 и старый SDK (например, 10.4u).

2010-06-11 18:36:31

Тогда мне нужно скачать старый SDK. Где я могу его найти? – 2010-06-11 20:00:26

SDK - это дополнительные установки в установщике Xcode - просто запустите программу установки и обновите SDK 10.4u и 10.5, если вы не установили их в первый раз. –

OMG! Я установил SDK 10.4 и использовал его. Теперь это приводит к более чем 60000 ошибкам компиляции): компиляция sux – 2010-06-11 20:14:02

11415 ошибки компиляции FTW?
