Compilation error with OTP-28

[GRoguelon]

Hi,

I have tried to upgrade my project to OTP 28.0.1 and Elixir 1.18.4-otp-28.

I got this error which prevents me to complete compilation:

Generating MyProject.Cldr for 2 locales named [:en, :und] with a default locale named :en

== Compilation error in file lib/my_project/cldr.ex ==

I have this module:

defmodule MyProject.Cldr do
  use Cldr, locales: [:en], default_locale: :en, providers: [Cldr.Number, Cldr.Calendar, Cldr.DateTime, Cldr.List]
end

I had a similar issue with my file endpoint.ex where I had a Regex in a module attribute, I tried to review the file lib/cldr/cldr.ex but I couldn't identify any of the deprecated changes of OTP-28.

Elixir 1.18 is not compatible with OTP 28. I'd suggest waiting for official support – likely with otp 28.1 for exactly that issue.

Edit: Seems like 1.18.4. is marked as compatible, but I'd still suggest waiting for OTP 28.1, which will fix the root cause of the issue in OTP.

FYI, with Elixir 1.19.0-rc.0-otp-28:

** (ArgumentError) ~r/[\:：﹕︓∶]/u contains a reference (#Reference<0.1558792702.3750625282.110130>) and therefore it cannot be escaped (it must be defined within a function instead).

That's still using OTP 28.0 though. The fixes will likely be in OTP 28.1: erlang/otp#9976

Thank you for sharing the OTP issue. I will wait for 28.1

All the ex_cldr libraries are expected to work on Erlang 28.0 and Elixir 1.18.4. So. your compilation error means I've missed something. I'm working on that now.

Can you share the library versions you are using? I've run a number of tests now on OTP 28.0.1 and Elixit 1.18.4-otp-27 without compilation error. Hence why I suspect you may not have updated your dependencies.

Sure thing, mix deps.tree | grep cldr:

Also: mix hex.outdated:

ex_cldr                        2.40.4   2.42.0  Update not possible
ex_cldr_dates_times            2.21.0   2.22.0  Update not possible

You'll need to relax your dependency configuration for ex_cldr. Typically you would have {:ex_cldr, "~> 2.42"} in order to support OTP 28 and the upcoming Elixir 1.19.

Basically, you need to be on the latest release of the all the ex_cldr libs to have OTP 28 support.

Just did it and ran our CI and everything looks good with Cldr 💪

Sorry for the false alert, thank you for the assistance.

Can I close this issue?

Glad you're back on track!
