Thank you! I'll give it a try tomorrow and comment if it worked.

fatal error: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/lipo: can't open input file: build/libLinkAPI.dylib (No such file or directory)

I managed to compile an arm version of the dylib:

build_osx64/libmod_MumbleLink.dylib: Mach-O 64-bit dynamically linked shared library arm64

I think I can make an x86 and amr64 dylib .. maybe it's time to drop 32bit and support a new version of universal binary (x86/arm)?

I'm not familiar with gradlew or all the java stuff so I can't compile the mod, but I'm willing to be the mac build and test environment to get this mod working on M1 Macs.

Hey! That sounds great. You do not need to compile the mod. All you should need to do is use some zip tool and replace the dylib inside the mod's jar file within it's darwin folder.

I am sorry. We still might have a problem ... I had not updated the natives folder in this repo see #8. It might be that you compiled for JNI and not JNA?

[jason-green-io]

I did compile the natives in the repo, the JNI ones. Honestly, I'm trying to use the fabric mod. I'm only here in a desperate attempt to try and get M1 Mac + mumble link + Mumble all natively without Rosetta in some form.

Seems like the fabric version doesn't require natives.

Edit: I can still try and make an x86/arm version for you though.

It does. It just does it a bit differently: https://github.com/magneticflux-/jvm-shared-memory
