【问题描述】:
我正在开发一个 iPhone 应用程序,在对我的代码进行了一些小的更改后,当我尝试构建时,当 XCode 尝试创建预编译头文件时,我突然收到以下构建错误:
i686-apple-darwin10-gcc-4.2.1: n: No such file or directory
Command /Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/gcc-4.2 failed with exit code 1
从构建日志中,我可以看到崩溃行如下:

由于某种原因,命令中间突然出现了术语“n” (... /DerivedSources n -c ...) ,据我所知,它确实不属于那里。
我尝试清空 XCode 缓存、清理项目、依赖项和预编译的头文件,但是在重建时我得到了同样的错误。
我还尝试恢复我在之前成功编译后所做的所有我能想到的更改,但没有运气。我还尝试重新安装 XCode (3.2.3),但没有成功。不过,其他项目似乎仍然可以正常编译。
这个“n”怎么可能突然出现在命令中,我有什么办法可以修改该行以使事情再次正常运行?
提前致谢!
【问题讨论】:
-
我设法解决这个问题的唯一方法是创建一个全新的项目,并将之前项目中的所有源文件添加到其中。现在程序编译得很好,所以至少代码文件不会弄乱XCode。我仍然很好奇是什么导致了这整个问题,以及如果我将来遇到它应该如何解决它。
