Compile error on Mac M1

[onehundredfeet]

I'm getting a compile error on the latest development branch. I'm on a Mac m1. I've been able to compile many times before, except now recently.

File "src/macro/eval/evalLuv.ml", line 97, characters 3-11: 97 | | `ENODATA -> 80

dune build --workspace dune-workspace.dev src/haxe.exe
File "src/macro/eval/evalLuv.ml", line 97, characters 3-11:
97 |    | `ENODATA -> 80
          ^^^^^^^^
Error: This pattern matches values of type [? `ENODATA ]
       but a pattern was expected which matches values of type Luv.Error.t
       The second variant type does not allow tag(s) `ENODATA

Sounds like the sequel to #10679.

Should I be upgrading generally? I'm always afraid to upgrade because I'm assuming you're using specific versions

[onehundredfeet]

I always run:

opam update

# install the haxe package dependencies (as listed in the `opam` file)
opam install haxe --deps-only

But I guess that's not enough.

[Simn]

I have yet to solve this locally myself, but opam upgrade luv is likely a good idea.

I'm wiping the opam cache and starting from scratch

I'm wiping the opam cache and starting from scratch

Yeah that sounds a lot of my typical opam upgrading experience...

[onehundredfeet]

Well, full wipe FTW. Thanks Simon.

[onehundredfeet]

5.0.0-alpha.1 is latest correct?

It's possible that you had ctypes pinned to an old version, our ci had issues until we unpinned it: #11765
