2. cd blog_phoenix
3. mix phoenix.server

The only other thing that I can think that could have caused this is me running the following:

~/D/E/website » mix local.hex

After locking the version of gettext back to 0.11.0 and running mix deps.get things seem to work as expected.

  defp deps do
    [{:phoenix, "~> 1.2.1"},
     {:phoenix_pubsub, "~> 1.0"},
     {:phoenix_ecto, "~> 3.0"},
     {:postgrex, ">= 0.0.0"},
     {:phoenix_html, "~> 2.6"},
     {:phoenix_live_reload, "~> 1.0", only: :dev},
     {:gettext, "0.11.0"},
     {:cowboy, "~> 1.0"}]
  end

Gettext v0.12.1 is out with a fix for this bug, this can be closed 👍

[steakunderscore]

Perfect, thanks @whatyouhide

[josevalim]

My bad! Glad @whatyouhide quickly caught it. :)

[xadhoom]

I'm having the same issue after upgrading my project deps.
On an existing project, my mix.lock reported gettext 0.11.0 and was working on.
Then after update it upgraded to 0.12.1 and I have the same error as the reporter.

My web/gettext.ex is basically empty:

defmodule DtWeb.Gettext do
  @moduledoc """
  A module providing Internationalization with a gettext-based API.

  By using [Gettext](http://hexdocs.pm/gettext),
  your module gains a set of macros for translations, for example:

      import DtWeb.Gettext

      # Simple translation
      gettext "Here is the string to translate"

      # Plural translation
      ngettext "Here is the string to translate",
               "Here are the strings to translate",
               3

      # Domain-based translation
      dgettext "errors", "Here is the error message to translate"

  See the [Gettext Docs](http://hexdocs.pm/gettext) for detailed usage.
  """
  use Gettext, otp_app: :dt_web
end

any hint?

locking to 0.11.0 makes it work again.

[josevalim]

@xadhoom what happens if you update and remove _build? Does it work or does it still breaks?

[xadhoom]

Same.

the error is:

== Compilation error on file web/gettext.ex ==
** (exit) exited in: GenServer.call(Gettext.ExtractorAgent, {:get, #Function<4.87779196/1 in Gettext.ExtractorAgent.extracting?/0>}, 5000)

Tried also fetching again deps (by cleaning deps and _build), but no change.

My mix.lock is: https://gist.github.com/xadhoom/e733395074ae750524afb47491d0f7d5

Using elixir 1.3.2

[josevalim]

Oh, it seems you are using an umbrella project. I wonder if that is the root cause. I will investigate.

[xadhoom]

yes, using an umbrella, sorry for not mentioning it .

[josevalim]

@xadhoom i cannot reproduce it. which command are you running that triggers the failure and on which directory?

[xadhoom]

just a simple: mix do deps.get, deps.compile, compile after the removal of the deps and _build dir

[josevalim]

From the umbrella root? or from the application? Do you have an application that depends on the foo_web application or the opposite?

[josevalim]

Furthermore, do you have another application that lists gettext as a dependency and changed the list of compilers to compilers: [:gettext] ++ Mix.compilers?

[xadhoom]

from the umbrella root. and yes, one of the app depends on the other two.

I've pushed all the repo (with mix updates) to here https://github.com/xadhoom/detectino-core/tree/updates

no other project requires gettext.
mmmh about compilers I have compilers: [:phoenix] ++ Mix.compilers, it must be updated ?

[josevalim]

mmmh about compilers I have compilers: [:phoenix] ++ Mix.compilers, it must be updated ?

Yes! Try doing [:phoenix, :gettext] ++ Mix.compilers. If that works, I will make sure to provide a decent error message. :)

[xadhoom]

EDIT: got it, it works :)

Adding both fixed it.

[xadhoom]

thanks!

[josevalim]

@xadhoom have you listed both :gettext and :phoenix in there?

[josevalim]

And make sure the :phoenix one comes first (it shouldn't matter though).

[xadhoom]

yes, I missed "both", now works perfectly. thanks!

[josevalim]

Beautiful!
