Xcode Apple LLVM编译器3.1错误
刚刚将Xcode更新为4.3，现在我无法构建我的应用程序。我得到了这个错误：Xcode Apple LLVM编译器3.1错误,xcode,clang,exit-code,Xcode,Clang,Exit Code,刚刚将Xcode更新为4.3，现在我无法构建我的应用程序。我得到了这个错误： Command /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang failed with exit code 254 还有谁有这个问题吗？这可能只是一个编译设置，但我不确定该在哪里查找 当然，这个错误包括整个堆栈转储，但为了简洁起见，我没有包括它。我希望有人知道什么是“退出代码254

我现在的问题是：为什么？您发现了一个编译器错误。看起来编译器的错误报告可以精确地指出代码中的错误，所以最好的办法是修改代码，看看是否可以使其更易于消化
您也可以提交错误报告，但这并不能及时解决问题。从4.2升级到4.3后，我遇到了相同的错误消息。通过检查转储，我能够找到导致编译器呕吐的类名和行 我相信每个人的原因都不一样，只是在这里添加了我的修正 从
[super.tabBarController setSelectedIndex:0]
到
[[super tabBarController]设置所选索引：0]
为我解决了这个问题。我认为点符号可以翻译成括号。如果有人能解释这个在XCode 4.2中不需要的修复，那就太好了。我也有同样的问题。在此代码中：
[super pxSeek:@"1"];
[super.SQL setString:[NSString stringWithFormat:@"%@ %@", @"SELECT COUNT(*) AS MYCOUNT FROM ", super.Name]];
[super executeSQL];
return [super getIntColumn:0];
我需要更改[[super SQL]的[super.SQL]，即调用该方法。我使用的是xcode 4.3，出现了与您类似的错误。这是一些错误，我刚刚重新启动计算机，错误就消失了。我试图通过NSLog输出就地操作的结果（返回void），从而在xcode 4.3.2上触发了这个问题
就我而言，我想做的是：-
NSLog(@"result = %@", [array filterUsingPredicate:predicate]);
FilterSingPredicate:
是一个返回void
的就地方法，这一事实似乎触发了此编译器错误。有趣的是，Xcode的输入错误检测并没有检测到它
将此更改为正确的版本：-
NSLog(@"result = %@", [array filteredArrayUsingPredicate:predicate]);
工作正常，解决了问题！我有一个复制粘贴错误，经常在截止日期较短时遇到：）
在.m文件中：
@implementation DetailGetter
... stuff here..
@end
我在上面复制粘贴了一个接口声明，但使用了其他名称
@implementation FromOtherMFile()
@end
@implementation DetailGetter
... stuff here..
@end
当然，如果将FromOtherMFile更改为DetailGetter，则不会出现编译器错误，但需要滚动整个页面，其中有错误，并且在编辑器中不会突出显示。从菜单栏中选择“查看”>“导航器”>“显示日志导航器”。单击最新的生成日志。找到失败命令的行。单击该行。单击E按钮在线路的右端显示命令和它的输出。粘贴命令并输出到你的问题。嗯，整个输出是长的。但是我将添加它。我也遇到了bug，虽然它不是在目标C代码中。当我尝试在C++中使用lambda表达式时，我得到了它。因此，似乎问题并不是孤立于D。Objective C方法中的ot语法。哦，还有一件事……我不明白错误的第一行为什么说正在使用clang版本1.0。有人知道为什么会这样吗？@Mattia我建议向苹果提交一个单独的错误，因为我为这个问题向他们提交的错误只涉及Objective-C。我不确定为什么它会说clang版本1.0在1.0上。我会仔细检查您的项目设置，确保您的编译器是“Apple LLVM Compiler 3.1”（或旧Xcode上的3.0）。如果是，那么我相信您应该没事。是的，刚刚添加了一个错误报告。
