If you think configure made a mistake, make sure you are using the latest
version from Git. If the latest version fails, report the problem to the
[email protected] mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "ffbuild/config.log" produced by configure as this will help
solve the problem.

我在执行./compile-ffmpeg.sh all时候出的错,xcode版本是9.3,有知道的吗?怎么解决那,git是最新版本的

[linuxliu]

查看一下 ffbuild/config.log

[xiaozhima]

降低xcode版本到9.0及以下

已经解决了,看的这个回答里面一个人的回答,我给复制过来了,不知道这个怎么能链接到他的回答上,就给复制了,

上面的方法不行的话 可能是 安转 anaconda 的时候把环境变破坏了 卸载掉试试
