Trying to compile the FFMPEG-3.4 with Android-NDK-16.1.
Compiling the source on Mac.
Getting below Warnings/Errors:

Please help to fix these errors. Due to these errors/warnings compilation is getting terminated.
Note: Android directory is getting created even after these errors. But I think library is not compiled properly due to above errors.
Let me know if anything else needed. Please help.
回答1:
Your build script is out of date and not compatible with modern NDKs (it doesn't follow https://android.googlesource.com/platform/ndk/+/master/docs/UnifiedHeaders.md#supporting-unified-headers-in-your-build-system).
I'd recommend saving yourself some trouble and using a standalone toolchain to handle the organizational bits for you.
