Символы не найдены ошибка при связывании приложения iPhone в XCode

/ 05 октября 2009

Всякий раз, когда я пытаюсь скомпилировать приложение для iPhone, которое я портирую, я получаю ошибки связывания. В приложении используется язык сценариев, называемый Squirrel (для чтения файлов уровней, что хорошо для SDK, пользовательский ввод отсутствует). Я связал все библиотеки, включая libsquirrel.a. Что я делаю неправильно? (Приложение - SuperTux, исходный код на supertux.lethargik.org для компьютерной версии).

Что-то странное может происходить с libstdc ++ - static.a. Даже не уверен, что это такое.

C ++ Filt - ваш друг, он разобьет эти имена, чтобы показать вам, чего не хватает: 

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

Кажется, что первая строка сверху указывает на то, что не удается найти определение метода create_squirrel_instace из класса Scripting.

Таким образом, порядок представления библиотек в g ++ (это компилятор, используемый на Mac) очень важен. Итак, взгляните на результаты сборки и посмотрите, сможете ли вы найти строку, где связаны библиотеки:

Это должно выглядеть так: 

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

Я переформатировал вывод abovre, чтобы он был читабельным: В тексте я заменяю

/Users/Thomas/Documents/iPhone Dev Projects./SuperTux с <DIR> для удобства чтения:

Целая куча библиотек не используется, потому что они имеют неправильную архитектуру:
