đã sao chép kiểm tra khả năng hiển thị từ quả táo, nhưng trình liên kết đưa ra lỗi

Question

tôi đã cố gắng sử dụng dự án khả năng hiển thị do táo phát hành để phát hiện khả năng hiển thị trong ví dụ của riêng mình. i sao chép khởi nhất, nhưng tôi nhận được thất bại này trong mối liên kết:

quên nó. Tôi chỉ không biết rằng tôi phải thêm khung định cấu hình hệ thống theo cách thủ công. Tôi nghĩ rằng nó sẽ được thêm vào khi nó được nhập khẩu.
