When compiling from source, global erlang version is used

[dylan-chong]

The local version of erlang should be used to compile elixir. This will prevent issues where you compile elixir after compiling erlang inside a repository with a different erlang version to the global, and encountering unexpected issues

@dylan-chong sorry for the late reply here. Can you provide the output of asdf info, any .tool-versions files you used, and the sequence of steps you performed that caused this issue?

asdf should already use the Erlang version you specified in your .tool-versions file if you've set it and the shims have been generate (asdf reshim).

Hi, this is specific to installing Elixir where the global erlang version differs from the local one inside a project. This I presume is because the cwd when installing erlang is outside the project, so the global version is used

You can also test this by unsetting the global erlang version in ~/.tool-versions
