Got the same issue as @edgar
Keep in mind that in order to get that error I had to point to XCode 15 using: sudo xcode-select --switch /Applications/Xcode-beta.app
I also tried compiling from the source:
$ git clone https://github.com/elixir-lang/elixir.git
$ cd elixir
$ make clean test
rm -rf ebin
rm -rf lib/*/ebin
rm -rf lib/elixir/src/elixir_parser.erl
rm -rf lib/*/_build/
rm -rf lib/*/tmp/
rm -rf lib/elixir/test/ebin/
rm -rf lib/mix/test/fixtures/deps_on_git_repo/
rm -rf lib/mix/test/fixtures/git_rebar/
rm -rf lib/mix/test/fixtures/git_repo/
rm -rf lib/mix/test/fixtures/git_sparse_repo/
rm -rf lib/mix/test/fixtures/archive/ebin/
rm -f erl_crash.dump
rm -f man/elixir.1
rm -f man/elixir.1.bak
rm -f man/iex.1
rm -f man/iex.1.bak
make: *** [lib/elixir/src/elixir_parser.erl] Bus error: 10
Also found a Github issue that reference this issue: Elixir broken on MacOS Sonoma · Issue #12684 · elixir-lang/elixir · GitHub
Which confirmed this was an erlang issue:
❯ erl
zsh: bus error erl
Then I tried the asdf approach: GitHub - asdf-vm/asdf-erlang: Erlang plugin for asdf version manager · GitHub
asdf plugin add erlang https://github.com/asdf-vm/asdf-erlang.git
asdf install erlang 26.0.1
asdf global erlang 26.0.1
You might need to asdf reshim YMMV.
After that erl still results in bus error, not sure why, but I was able to compile, and run a repl with Elixir now:
❯ iex -S mix
Erlang/OTP 26 [erts-14.0.1] [source] [64-bit] [smp:10:10] [ds:10:10:10] [async-threads:1] [jit]
Interactive Elixir (1.15.0) - press Ctrl+C to exit (type h() ENTER for help)
iex(1)>
