Chỉ cập nhật Xcode thành 4.3 và giờ tôi không thể xây dựng ứng dụng của mình. Tôi gặp phải lỗi này:Lỗi trình biên dịch LLVM của Apple 3.1 lỗi
Command /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang failed with exit code 254
Bất kỳ ai khác có vấn đề này? Nó có lẽ chỉ là một thiết lập biên dịch nhưng tôi không chắc chắn nơi để tìm.
Tất nhiên, lỗi này bao gồm toàn bộ bãi chứa ngăn xếp, nhưng tôi chưa bao gồm điều đó vì lợi ích ngắn gọn. Tôi hy vọng rằng ai đó sẽ biết "exit code 254" là gì. Đã cố gắng tìm kiếm nó nhưng không thể tìm thấy bất cứ điều gì.
Dưới đây là toàn bộ sản lượng:

CẬP NHẬT Vì vậy, tôi nhận thấy rằng các bãi đề cập đến dòng cụ thể về mã trong một lớp học cụ thể (SCheckBox.m). Đó là phương pháp init. Tôi đã kiểm tra phương pháp nhưng không thể tìm thấy bất cứ điều gì sai trái với nó. Tuy nhiên, nếu tôi nhận xét mọi thứ bên trong phương thức và trả về nil, thì mã sẽ biên dịch. Tôi đã đi qua và uncommented mỗi dòng cho đến khi tôi nhận được lỗi. Lỗi gây ra sự cố là:
[super.inputField addSubview:_checked];
Tôi đã dự định sử dụng 'tự' thay vì 'siêu' (lỗi chính tả). Nhưng siêu trong thực tế có một thuộc tính inputField. Nó không được định nghĩa lại hoặc ghi đè trong lớp con. Vì vậy, truy cập 'super.inputField' vs 'self.inputField' nên truy cập chính xác điều tương tự (và đã làm trước khi nâng cấp Xcode). OK, vì vậy việc thay đổi 'super' thành 'self' sẽ khắc phục được sự cố.
Câu hỏi của tôi bây giờ là: Tại sao?
Từ thanh trình đơn, chọn Xem> Trình điều hướng> Hiển thị nhật ký điều hướng. Nhấp vào nhật ký xây dựng mới nhất. Tìm dòng lệnh không thành công. Nhấp vào dòng. Nhấp vào nút ở đầu bên phải của dòng để hiển thị lệnh và đầu ra của lệnh. Dán lệnh và đầu ra vào câu hỏi của bạn. –
Vâng, toàn bộ đầu ra dài. Nhưng tôi sẽ thêm nó. –
Tôi cũng gặp lỗi mặc dù nó không nằm trong mã C Mục tiêu. Tôi nhận được nó khi tôi cố gắng sử dụng biểu thức lambda trong C + +. Vì vậy, có vẻ như vấn đề không bị cô lập với cú pháp dấu chấm trong các phương pháp C Mục tiêu. – Mattia
