I spoke too soon. It would appear that comeonin will compile with an older intel version of elixir (1.10.4-otp-23 in my case) Erlang (23.0.3 in my case), but fails on bcrypt when compiling on the latest elixir 1.11.2-otp-23 Erlang 23.2.1 for apple silicon.
Continuing investigation.
My particular issue was a VSCode architecture mismatch.
Posting the solution here in case anyone else experiences this side effect like I did.
Very smooth fully native M1 Arm installation now via latest Homebrew and asdf-vm; be sure to install the Erlang dependencies autoconf and wxmac before installing Erlang, as specified in the asdf-erlang instructions.
Of note: the scheduler sees all 8 cores, including the low-power ones:
Erlang/OTP 23 [erts-11.1.7] [source] [64-bit] [smp:8:8] [ds:8:8:10] [async-threads:1]
so it might be interesting to learn how that performs in practice.
Not sure if anyone’s seen this yet, but I’ve installed elixir 1.9 and erlang/otp 23 and almost all elixir compilation errors are swallowed and only a single stack-less “argument error” is spat out, ie:
== Compilation error in file test/support/factory.ex ==
** (ArgumentError) argument error
Even when I compile on the same machine in docker, the compilation errors are reported correctly, so it might actually be a Big Sur issue, but I have no idea as to the root cause.
Hopefully this is of use/interest to someone.
How I got Elixir/Phoenix working on an Apple M1
[MacBook Pro (M1 2020), chip Apple M1, MacOS Big Sur 11.3.1]
I installed the latest Elixir/OTP with Homebrew
$ brew install elixir
but found that my Phoenix projects wouldn’t run.
Eg. GitHub - pdxrod/article_editor · GitHub
failed with
** (EXIT) no process: the process is not alive or there's no process currently associated with the given name, possibly because its application isn't started
So I tried starting with a simpler project,
https://github.com/pdxrod/simple_mongo_app
This had a different issue, to do with Mongo and its Elixir driver
{:mongodb, "~> 0.5.1"}
The latest Elixir downloaded by Homebrew was 1.12.1, with Erlang/OTP 24. My project was created using Elixir 1.11.2, with Erlang/OTP 23.
The MongoDb driver 0.5.1 uses crypto.hmac/2, and OTP 24 wants crypto.hmac/3, so the project wouldn’t compile and run.
** (UndefinedFunctionError) function :crypto.hmac/3 is undefined or private
Attempts to upgrade plug_crypto, as recommended here, made no difference.
I couldn’t figure out how to downgrade Elixir and Erlang using Homebrew, asdf, kiex, kurl or exenv. So I deleted all copies of both, and switched to using Macports.
sudo port install erlang @23.1
sudo port install elixir @1.11.2
mix deps.get
mix phx.server
Bingo!
This tells you how to install a given version of something with Macports
I installed Macports by finding MacPorts-2.7.1-11-BigSur.pkg here
Release MacPorts 2.7.1 · macports/macports-base · GitHub downloading and double-clicking on it.
Downgrading to Elixir 1.11 isn’t a permanent solution, so I’m going to look into other Mongo drivers, so see if any of them work with 1.12.
The crypto error can be easily addressed too, in case you want to submit a pull request. Here is how it was handled in plug_crypto: Use crypto new API (#20) · elixir-plug/plug_crypto@cf901bd · GitHub
For anyone wanting to run Elixir 1.11 and OTP 23 this guide worked well for me on an M1 Max in Monterey.
I made sure to install the latest homebrew, then asdf and plugins. Its key to do this from native terminal and NOT a rosetta terminal.
Could you please clarify, is Elixir and Erlang runs natively on M1? So no rosetta involved? And it means that it uses full CPU potential?
Thanks!
It does, I’ve set up Erlang 24.1.3 and Elixir .1.12.3 on both the MacBook pro 13inch M1 and the 14inch M1Max with no issues using asdf-vm
