Apple LLVM 컴파일러 3.1 오류

Question

Xcode를 4.3으로 업데이트 했으므로 이제 앱을 빌드 할 수 없습니다. 이 오류가 나타납니다.

Command /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang failed with exit code 254 

다른 사람이이 문제가 있습니까? 아마도 컴파일 설정 일 뿐이지 만 어디서 볼 것인지 잘 모르겠습니다.

물론 오류에는 전체 스택 덤프가 포함되지만 간결함을 위해 포함되지 않았습니다. 누군가가 "exit code 254"가 무엇인지 알게되기를 바랍니다. 그것을 찾으려고했지만 아무 것도 찾을 수 없었습니다. 덤프가 특정 클래스 (SCheckBox.m) 코드의 특정 라인에 참조하는 그래서 내가 발견

UPDATE :

다음은 전체 출력입니다. 그것은 init 메소드에 있습니다. 나는 그 방법을 조사했지만 그걸로 아무 것도 찾을 수 없었다. 그러나 메서드 내 모든 것을 주석 처리하고 nil을 반환하면 코드가 컴파일됩니다. 나는 오류가 발생할 때까지 모든 라인의 주석을 제거하고 주석을 제거했다.

[super.inputField addSubview:_checked]; 

내가 대신 (내 부분에 오타했다) '슈퍼'의 '자기'를 사용하여 구성했다 : 문제의 원인이 오류는 이것이다. 하지만 super에는 실제로 inputField 속성이 있습니다. 하위 클래스에서는 재정의 또는 덮어 쓰지 않습니다. 그래서 'super.inputField'와 'self.inputField'에 액세스하는 것은 똑같은 일을해야합니다 (그리고 Xcode를 업그레이드하기 전에 했어야합니다). 좋습니다. '슈퍼'를 '자기'로 변경하면 문제가 해결됩니다.

내 질문은 지금입니다 : 왜?

Answer 1

컴파일러 버그를 발견했습니다. 컴파일러의 오류보고는 코드에서 바코드의 위치를 ​​정확하게 보여 주므로 최선의 방법은 해당 코드를 사용하여 더 쉽게 소화 할 수 있는지 확인하는 것입니다.

버그 보고서를 제출할 수도 있지만 문제가시기 적절하게 해결되지는 않습니다.

Answer 2

4.2에서 4.3으로 업그레이드 한 후에도 동일한 오류 메시지가 나타났습니다. 덤프를 검사하여 클래스 이름과 컴파일러가 토해내는 선을 찾을 수있었습니다.

나는 모두를위한 원인이 다르지만 여기에 내 수정 사항을 추가 할 것이라고 확신합니다.

[[super tabBarController] setSelectedIndex:0];

에

[super.tabBarController setSelectedIndex:0];

에서 변경 나를 위해 문제를 해결. 그래도 점 표기법은 대괄호로 번역된다고 생각했습니다. 누군가 Xcode 4.2에서 필요하지 않은이 수정을 설명 할 수 있다면 좋을 것입니다.

Answer 3

나는 동일한 문제가있었습니다. 이 코드에서 :

[super pxSeek:@"1"]; 
[super.SQL setString:[NSString stringWithFormat:@"%@ %@", @"SELECT COUNT(*) AS MYCOUNT FROM ", super.Name]]; 
[super executeSQL]; 

return [super getIntColumn:0]; 

난 그 방법을 호출하는,] [[슈퍼 SQL에 대한 [super.SQL] 변경해야합니다.

Answer 4

메신저로 xcode 4.3을 사용하고 있습니다. 오류가 발생했습니다.그것은 약간의 버그였습니다. 저는 컴퓨터를 재부팅하고 오류가 사라졌습니다.

Answer 5

무효를 반환하는 내부 작업 결과를 NSLog를 통해 출력하려고 시도하여 Xcode 4.3.2에서이 문제를 트리거 할 수있었습니다. 내 경우

은, 내가 뭘하려고했던 것은이었다 -

NSLog(@"result = %@", [array filterUsingPredicate:predicate]); 

filterUsingPredicate:가 void이 컴파일러 오류를 유발 한 것으로 보인다 반환에서 적절한 방법이라는 사실. Xcode의 as-you-type 오류 탐지가 문제가되지 않는다는 것이 흥미 롭습니다.

올바른 버전이 변경 : -

NSLog(@"result = %@", [array filteredArrayUsingPredicate:predicate]); 

잘 작동하고 문제를 해결!

@implementation DetailGetter 
... stuff here.. 
@end 

내가이 위의 인터페이스 선언을 복사 - 붙여 넣기 것보다 있지만 : 기한이 짧은 :)

하는 .m 파일의 경우

Answer 6

내가하는 복사 - 붙여 넣기 오류가 발생한 자주 만났다 다른 이름으로

@implementation FromOtherMFile() 
@end 

@implementation DetailGetter 
... stuff here.. 
@end 

물론, 어떤 컴파일러 오류가 없습니다 DetailGetter하는 FromOtherMFile을 변경하지만, 오류가 전체 페이지를 스크롤하는 데 필요한, 그리고 난을 강조하지 않는 경우 편집기.
