Compiling on Intel MacOs

[konpatsourakis]

Hello,
have you managed to compile on a MacOS ? Also do I need a specific version of rust compiler ?
I can try and provide some errors but they are different depending on the version I am using

Thanks!

Hello, I have not tried compiling on OS X (mainly because I don’t have a mac)

I’m happy to take a look at your errors but it might be slow trying to fix it from my end unless I get my hands on mac!). I do want to fix a Mac release though.

Thank you,
when I am trying to compile with stable rustc 1.68.2
I am getting this:

$ synja % cargo nih-plug bundle synja --release

So I change to nightly 1.70.0

I run the commands again and I am getting this

$ cargo nih-plug bundle synja --release

If you need something else please let me know!
I have very limited experience with rust so it might be something obvious

A bit unsure what’s going on, maybe the feature has been renamed from once_cell to lazy_cell or something.

try adding

#![feature(lazy_cell)]

to the top of lib.rs and compile again
