Как решить проблему совместимости разрядности между 32-битной DLL и 64-битным Java-приложением на macOS

Delphi , Файловая система , DLL и PlugIns

Перед тем как перейти к решению проблемы, важно понять, что 32-битные и 64-битные приложения используют разные соглашения о вызовах и могут не совместимы друг с другом. В случае с macOS, операционная система использует специфические динамические библиотеки, которые не совместимы с Windows DLL.

Описание проблемы

Пользователь столкнулся с проблемой при попытке использования 32-битной DLL, созданной на Delphi, в 64-битном Java-приложении на macOS. При запуске проекта возникала ошибка java.lang.UnsatisfiedLinkError, указывающая на отсутствие библиотеки в пути java.library.path.

Решение проблемы

Подтвержденный ответ

Использование 32-битных Windows DLL в macOS невозможно, за исключением случаев, когда macOS запускает виртуальную машину Windows. Однако, это не является оптимальным решением.

Альтернативные решения

1. Перекомпиляция DLL под macOS

Для использования 32-битной DLL на macOS, необходимо перекомпилировать её с помощью компилятора, предназначенного для macOS, например, с использованием Delphi XE2 для macOS или FPC (Free Pascal Compiler), который поддерживает создание библиотек, совместимых с macOS.
