Подтвердить что ты не робот

По крайней мере, один модуль имеет неразрешенный импорт из-за отсутствия функции экспорта в неявно зависимом модуле

Когда я укажу на свою С++-dll из DependencyWalker, я вижу сообщение об ошибке "Как минимум один модуль имеет нерешенный импорт из-за отсутствия функции экспорта в неявно зависимом модуле"

Не могли бы вы предложить, что такое ошибка?

Ответ 1

Ваша dll (или DLL, которую он импортирует) имеет импорт из другой dll (bad.dll say). Когда DependencyWalker сканирует bad.dll, он обнаруживает, что он не экспортирует требуемую функцию. Этот недостающий экспорт будет помечен красным цветом (или немногочисленным) в списке импорта dll.
