Fat binary on macOS M1

[tmspzz]

When compiling libsodium from source, is the a way to obtain a fat binary with x86_64 and arm64 archs?

Seems like in some cases JVMs for x84_64 only are asking the linker to get the x84_64 slice on M1 too.

The dist-build/apple-xcframework.sh script builds FAT libraries. You can even directly use the pre-compiled libraries from swift-sodium.

Thanks for acknowledging. I will take a look.

On the surface tho if those are .xcframeworks that won't solve the current issue we're facing with .dylib since arch/platforms are still separated and not a FAT binary.

It would be golden to have Mac support for Universal/fat libs added i.e. removing

libsodium/configure.ac

Line 682 in 25d2455

AC_MSG_ERROR([universal endianness is not supported - compile separately and use lipo(1)])

@peter-toft-greve Ignore what was written above. Files in the xcframework are fat libraries.

@jedisct1 OOh you have my attention - can I generate libsodium using xcframework for MacOS which supports x86_64 and arm64?
Do you have a pointers towards this?
