I recommend using the latest development version of Lime 8 (which we’ll be releasing soon) if you want to target HashLink. We recently merged a pull request that includes the latest HashLink 1.12 and cleans up some of the messy parts of using HashLink with previous versions of Lime. I can confirm it works really well on my M1 Mac.
The easiest way to test a nightly build is to grab a lime-haxelib.zip file from one of the newest successful builds here:
Run the following command to install the downloaded file:
haxelib install lime-haxelib.zip
