@kewlbear 问题已经解决了,看了看日志看到别人的回到解决了,答案给复制过来了

看下日志 ios/ffmpeg-armv7/config.log 中发现报错说 iphoneos 找不到
SDK "iphoneos" cannot be located

这句报错 是根源
在执行编译脚本中，遇到一句xcrun --sdk iphoneos --show-sdk-path报错

mac$ xcrun --sdk iphoneos --show-sdk-path
xcrun: error: SDK "iphoneos" cannot be located
查找原因：

mac$ xcode-select --print-path
/Library/Developer/CommandLineTools
发现是这个Xcode路径判断错误。

mac$ xcodebuild -showsdks
xcode-select: error: tool 'xcodebuild' requires Xcode, but active developer directory '/Library/Developer/CommandLineTools' is a command line tools instance
回想起最近安装了另外两个版本的Xcode，应该是这样导致了路径错误。

mac$ ls /Applications/Xcode
Xcode.app/ Xcode2.app/ Xcode3.app/
解决方法：给Xcode命令行工具指定路径

mac$ sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer/
再回头查看

复制代码
mac$ xcrun --sdk iphoneos --show-sdk-path

接着编译即可解决问题
这种因为Xcode 不同版本前后的位置变化 导致，编译的脚本未做更新
开源软件 哎 疼点就是 问的问题没人理睬 希望上面的对其他有帮助

Exactly same error as above, in config.log the message said:
SDK "iphoneos" cannot be located.

The problem solved by
sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer/

Thanks for @qiweiqiang10's solution.
