Hi,
I developed a small program that uses ecto + ecto_sqlite3 and as a nested dependency exqlite.
The program works fine when I execute it with mix run, but when I try to compile it to an escript fails to run.

It crashes right at the startup with the following warning + error messages:

13:22:19.172 [warn]  The on_load function for module Elixir.Exqlite.Sqlite3NIF returned:
{:function_clause,
 [
   {:filename, :join, [{:error, :bad_name}, 'sqlite3_nif'],
    [file: 'filename.erl', line: 454]},
   {Exqlite.Sqlite3NIF, :load_nifs, 0,
    [file: 'lib/exqlite/sqlite3_nif.ex', line: 14]},
   {:code_server, :"-handle_on_load/5-fun-0-", 1,
    [file: 'code_server.erl', ...]}
 ]}

It ‘may’ be relate to a warning that is logged during compilation of the exqlite dependency:

Has anyone ever encountered similar problems with exqlite?

Since it works fine when it’s executed with mix run, might it be related to some incompatibility related to WSL2? Or could it be another reason entirely?

Thanks in advance.
