Закрытие приложения после запуска

Наконец-то я получил код для компиляции, однако он закрывается каждый раз, когда я его запускаю. Может ли кто-нибудь посоветовать мне, что не так?

Ниже приведен манифест, логарифм и верхняя половина кода в действии.

это прикладной проект, сделанный одним кодером. он использует родную библиотеку. Я скомпилировал родную библиотеку с помощью cygwin. он может успешно скомпилироваться. для ошибки «не удалось загрузить необходимую библиотеку libiconv.so для libexif2.so» (load_library[1108]: библиотека libiconv.so не найдена) 01-20 14:08:19.791», я проверил, эти Создано 2 файла. есть ли еще место, куда мне нужно поместить файл библиотеки?
