@wisenight I met the same problem.
In iOS devices, armv7 means iPhone 4 or iPad 1 and so on, armv7s meas iPhone 5 and so on, all it's 32 bit device. And Apple has required all apps should run on 64 bit.
So I just compiled arm64 and armv7s. The iPhone 4 or iPhone 5 is too old for our apps or Foundation/UIKit API.

If there's any mistake or any better solution, please tell me.

@Shvier
I do same thing like you.
I remove the armv7 in compile-ffmpeg.sh
FF_ALL_ARCHS_IOS8_SDK="arm64 i386 x86_64"

Thanks for your reply.

[HatsuneMikuV]

I can confirm that you upgraded the system today and upgraded xcode, so that's the problem.

[even3yu]

I has the same error,as I upgraded the system and xcode

[quanhaifeng]

I met the same problem

[emsihyo]

1. download xcode 9.1
2. sudo xcode-select -s pathToXcode9.1/Contents/Developer
3. ./compile-ffmpeg.sh clean
4. ./compile-ffmpeg.sh all
   best wishes.

上面的老哥说的对,完美.

@wisenight Does not compiling the armv7 will not be a problem?

莫非真要删除掉armv7?

Hi Zeaa, after these modifies , you also need rebuild openssl module.
try this step. it works for me . MacOS 1015.4, XCode 11.3 (11C29)

./init-ios-openssl.sh
./compile-openssl.sh clean
./compile-ffmpeg.sh clean
./compile-openssl.sh all
./compile-ffmpeg.sh all
