我一直试图找到问题几个小时而没有结果。 我已经更新到Xcode 6并在ioS8.0和i上都出现了这个错误。 7.1从那以后:
Undefined symbols for architecture armv7:
"___gnu_f2h_ieee", referenced from:
_playbackCallback in Audio.o
ld: symbol(s) not found for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)
感谢您的帮助。

我也遇到了一个非常类似的问题并发现了这一点。它解决了这个问题,非常有帮助。 http://helpdesk.metaio.com/questions/35905/undefined-symbols-for-architecture-i386-xcode-6-ios-8-beta-6/36538
创建.c文件(名称不是问题,在我的情况下,我制作了i386Symbols.c)并将其添加到项目中。然后粘贴它。

我无法解决问题,但我有部分解决方法
似乎许多浮点函数没有armv7
切片。我假设它们将被包含在Xcode 6的后续版本中(或最终版本中)。
存在armv7s
切片:因为我在使用后一个指令集的iPhone5上进行调试,所以我只需要从构建设置中删除该体系结构。
$(ARCHS_STANDARD)
并将其替换为armv7s
。Active Architecture Only
选项从YES
切换为NO
。这将允许构建和运行。不幸的是,我没有要测试的arm64
设备,但也可能包含此切片。
