Argon2 just doesn’t seem to want to compile.
Whenever I try to use Argon2, this happens:
iex(1)> Argon2.Base.init()

I’ve already tried cleaning all dependencies, reinstalling them. I checked and yes I do have a C compiler. I’m starting to worry that this won’t work on Apple Silicon.
The error suggests that it’s not finding the artifact it expects, but if that failed to compile it should show up in the output of mix deps.compile --force. Weird.
I don’t have an M1 to test with, but one way I imagine this could happen is if the dependency compilation and the iex were mismatched - one on Rosetta and the other not.
Did some digging around, found something interesting.
Firstly, I cloned the argon2_elixir GitHub onto my M1 Pro machine.
Fetched the dependencies, and ran make.

You need to have gcc and make installed. Try running the
commands "gcc --version" and / or "make --version". If these programs
are not installed, you will be prompted to install them.

I’m not a C developer by any means, so I’m just relying on Stack Overflow, but it seems like some file is missing for some reason.
Okay, so I took the dependency straight out of the /deps folder and use that instead. Got the same results as you.
So, I dug a little deeper and went looking around to see where the error was being thrown. Turns out it came down to this function:
defp load_nif do
path = :filename.join(:code.priv_dir(:argon2_elixir), 'argon2_nif')
:erlang.load_nif(path, 0)
end
So, I ran this code directly in the IEX shell, and this happened:
iex(2)> :erlang.load_nif(:filename.join(:code.priv_dir(:argon2_elixir), 'argon2_nif'), 0)
{:error,
{:bad_lib,
'load_nif/2 must be explicitly called from the NIF module. It cannot be called through apply/3.'}}
Looks like Erlang isn’t happy. Any good Erlang/C people that can parse this message?
That message basically means what it says: you can’t call :erlang.load_nif/2 from anywhere except within a nif module. So unfortunately we’re no further forward at this point.
I finally found out what it was. As someone suggested earlier in the thread, x86_64 binaries where being compiled instead of arm64 ones. Not sure why, but I found the fix.
Run gcc --version, and copy the target (in my case, arm64-apple-darwin21.2.0)
$ gcc --version

Open /deps/argon2_elixir/Makefile and add this line: CFLAGS += -target (your target)
Open mix.exs and change {:argon2_elixir: "~> 2.0"} to {:argon2_elixir, path: "deps/argon2_elixir"}
Ahhh. Ok, don’t have Rosetta installed here… found this running down related posts about M1 and argon2 failed compile issues. (None of which followed up w/ solutions…)
However… finally figured out what broke it. There’s a space in my project pathname. While that shouldn’t be a problem looks like it is – moved my project dir so no space, and getting a good compile.
