Installing Elixir on an Nvidia Jetson Nano development board

Questions / Help

I am attempting to install Elixir on an Nvidia Jetson Nano development board. This board runs ubuntu 18.04 LTS, on a 4-core ARMv8 rev 1 (v8l) processor. I’ve attempted to install using the distributions, then precompiled packages, and then compiling from source. Erlang/OTP 20 seems to install OK, following the instructions for the ubuntu distribution, but then continuing it installs elixir 1.3.3. iex works, but elixir --version terminates abnormally.
Any help appreciated!

Could you share any error message printed please? :slight_smile:

give asdf a try…

Elixir 1.3 is definitely not compatible with OTP 20. Weird that that’s the version that’s showing up. I’d consider using asdf as suggested by @outlog to a modern version of the language.

@lpil I’m just trying this now using the Raspberry Pi instructions from the elixir-lang.org site. I get the following when I try to get the elixir and iex versions:

$ elixir -v
Erlang/OTP 20 [erts-9.2] [source] [64-bit] [smp:4:4] [ds:4:4:10] [async-threads:10] [kernel-poll:false]

I was able to install Elixir using the Nerves installation instructions. I’m running Ubuntu 18.04.

@greghgradwell what version of elixir and OTP did you install (and on the Nvidia Jetson Nano, right?)

@holder66 Yes, this is on the Nano, with L4T 32.1.0 (I haven’t updated to 32.2 yet). I just used the same commands as the ones in the document, so I’m assuming it’s Erlang 22.0.7, and Elixir 1.9.1.

It definitely takes a while to install Erlang on the Nano. When it was building the source code I got a couple warnings about some Docs not being available, and then it appears to be unresponsive, but just let it keep running. Had all 4 CPUs maxed out for like 30 minutes (or at least it felt that long).
