Символы не обнаружены при подключении приложения iPhone в Xcode

Question

Всякий раз, когда я пытаюсь скомпилировать приложение для iPhone, которое я портирую, я получаю ошибки связывания. Приложение использует скриптовый язык Squirrel (для чтения файлов уровня, отлично с помощью SDK, без ввода пользователем). Я связал все библиотеки, включая libsquirrel.a. Что я делаю не так? (приложение SuperTux, исходный код на supertux.lethargik.org для компьютерной версии).

Что-то странное может быть происходит с libstdC++ - static.a. Даже не уверен, что это такое.

Answer 1

C++ ФИЛТР ваш друг будет unmangle эти имена, чтобы показать вам, что отсутствует:

> c++filt __ZN9Scripting24create_squirrel_instanceEP4SQVMPNS_12AmbientSoundEb 
Scripting::create_squirrel_instance(SQVM*, Scripting::AmbientSound*, bool) 

Первая строка сверху, кажется, указывает, что он не может найти определение метода create_squirrel_instace из класса Scripting.

Значит, порядок, который библиотеки представляют g ++ (который является компилятором, используемым на Mac), важен. Так что посмотрим на выходе сборки и посмотреть, если вы можете найти строку, в которой связаны библиотеки:

Он должен выглядеть следующим образом:

g++ <STUFF> -l<lib1> -l<lib2> etc. 

Я reformated выход abovre так читаем: в тексте я заменить

/Users/Thomas/Documents/iPhone Dev Projects./SuperTux с <DIR>, чтобы помочь читаемости:

целая куча библиотек не используются becuase они неправильно архитектура:
