c++ - ffmpeg armv7s 编译段错误

Question

我用 https://github.com/kewlbear/FFmpeg-iOS-build-script编译ffmpeg，
但是当我尝试编译时，对于 armv7s 架构我有下一个错误

所有其他拱门编译正常

clang: error: unable to execute command: Segmentation fault: 11 clang: error: clang frontend command failed due to signal (use -v to see invocation) Apple LLVM version 6.1.0 (clang-602.0.49) (based on LLVM 3.6.0svn) Target: arm-apple-darwin14.3.0 Thread model: posix clang: note: diagnostic msg: PLEASE submit a bug report to http://developer.apple.com/bugreporter/ and include the crash backtrace, preprocessed source, and associated run script. clang: note: diagnostic msg:

几个月前全部编译没有任何错误。
尝试了几个版本的 ffmpeg

这是 Clang -v

Apple LLVM version 6.1.0 (clang-602.0.49) (based on LLVM 3.6.0svn) Target: x86_64-apple-darwin14.3.0 Thread model: posix

和 xcode 版本是版本 6.3.1 (6D1002)

我想我找到了一个解决方案，正如您可以从这篇文章 http://www.cocoanetics.com/2014/10/xcode-6-drops-armv7s/ 中理解的那样xcode 目前不支持 armv7s，所以 armv7s 将使用 armv7 版本，并且不能降低性能。
