`elixir -v`

```elixir
Erlang/OTP 24 [erts-12.0.3] [source] [64-bit] [smp:8:8] [ds:8:8:10] [async-threads:1] [dtrace]

Elixir 1.8.2 (compiled with Erlang/OTP 24)

```

`~/.mix/rebar3 --version`

```elixir
rebar 3.13.3 on Erlang/OTP 24 Erts 12.0.3

```

Error I am getting while compiling lz4

Try upgrading your rebar with `mix local.rebar`, `erlang:get_stacktrace/0` was removed in OTP 24.

Additionally Elixir 1.8 only supports up to Erlang/OTP 22 so you should either upgrade Elixir (preferable) or downgrade Erlang/OTP.
