Cannot compile ssl_verify_fun in Windows 11

Fl4m3Ph03n1x

Background

I have a phoenix application in Windows 11. Unfortunately for me, I cannot compile the application because of a dependency error in Windows.

What I tried

First I tried the downloading Erlang from the official website (Downloads - Erlang/OTP), and Elixir
1.15.4 for OTP 26 (Installing Elixir - The Elixir programming language)

Unfortunately for me, I was greeted with an error when running mix phx.server.

$ mix deps.compile ssl_verify_fun
==> ssl_verify_fun
Compiling 7 files (.erl)
src/ssl_verify_hostname.erl:16: can't find include lib "public_key/include/public_key.hrl"

So, this lead me into this Elixir thread where the same issue happens for Ubuntu:

The solution found was for the user to install a special erlang package for Ubuntu, erlang-dev. However, since I am on Windows, I don’t really have that option.

So I removed both Erlang and Elixir and installed them using scoop, hoping the older versions of both Elixir and Erlang available there would be free of this issue.

With scoop I am now using:

elixir 1.15.4   main   2023-07-27 10:27:04
erlang 25.3.2.4 main   2023-07-27 10:10:31

Error

However, this still does not fix the issue, as I am greeted with a barrage of errors:

At this point, given my setup is on Windows, I don’t know what else to try.

Question

How can I fix this issue?

Hate to be that guy but have you considered using WSL2 and install whatever Linux you want inside of it?

After some more digging I found out this issue:

https://github.com/elixir-lang/elixir/issues/12653

Which represents my problem. Basically Elixir does not check the correct paths for the missing file:

https://github.com/elixir-lang/elixir/issues/12681

Now, there is a possible workaround for this issue. By forcing your application to use a more updated version of the dependency in question (ssl_verify_fun), you can add this to your mix.exs file:

 {:ssl_verify_fun, "~> 1.1.7", manager: :rebar3, override: true}

However, I don’t really like this. If tomorrow the same thing happens, you have to overwrite again. And when overwrites start conflicting with each other, then you really have a problem.

In my case, I found which application was using the old version of ssl_verify_fun by looking at mix.lock. It was hackney.

I still don’t fully understand if updating hackney will fix this issue without the need to use override.

I develop in Windows because my application is for Windows users. I literally have no other choice if I want to use Elixir.

Besides, given my investigation, I have reason to believe this is not a Windows specific issue, even though I admit I have found my fair share of them thus far …

Instead of going through every dependency and trying to fix it, I took the more nuclear approach. I deleted my mix.lock and then run mix deps.update --all.

This forced some older dependencies to update. After that a simple mix deps.get fixed the issue and mix phx.server worked.

can confirm that i got this error on Ubuntu after upgrading to 1.15. updating to :ssl_verify_fun, "~> 1.1.7" fixed it (I didn’t override). i did also do the nuclear option, not sure if it was needed, but worked out.

Note that this error can also happen with the combination of :ssl_verify_fun version < 1.1.7 and Elixir version >= 1.15. You’ll need to either upgrade :ssl_verify_fun or use an older version of Elixir.
