Erlang/OTP 21.1.4 is missing but only for arm 64

Could we please get otp 21.1.4 for arm 64 as well? It’s available for Arm32 arm and intel.

many thanks

boing…
some advice here would be great

I am not familiar with both erlang and elixir

Your .travis.yml and the CI result page show the language: elixir.

language: elixir

https://travis-ci.com/volvo-cars/signalbroker-server/jobs/266689054
“Elixir: 1.7.4 OTP Release: 21.1.4”

Do you want to use Erlang? or Elixir?

Can you put the tag “Multi CPU Architecture” to this thread as it is ?
https://travis-ci.community/c/environments/multi-cpu-arch/96

It’s available for Arm32 arm and intel.

How did you know it was available on Arm32 and Intel?

I am seeing your arch: arm32 case.

https://travis-ci.com/volvo-cars/signalbroker-server/jobs/266689053

And the result is 64-bit.

$ elixir --version
Erlang/OTP 21 [erts-10.1.3] [source] [64-bit] [smp:2:2] [ds:2:2:10] [async-threads:1] [hipe]

And now I a little understand that elixir is a language on Erlang.

In the meantime, is elixir installed in language: generic environment?

Or how about just using available version of Erlang/otp version, seeing the document if there is elixir? https://docs.travis-ci.com/user/languages/elixir/

matrix:
  include:
    - arch: amd64
      elixir: '1.7.4'
      otp_release: '21.1.4'
    - arch: arm64
      elixir: '1.7.4'
      otp_release: 'X.Y.Z'

And it’s weird. And I am not sure that arch: arm32 is available.
There is no arm32 in the document.

This thread’s category “Languages Erlang” is a little wrong isn’t it?
There is a category “Languages Elixir” here.

well looking through my simple .travis.xml i actually use docker for building. So the dependency issue is gone by removing elixir and otp.

results here https://travis-ci.com/volvo-cars/signalbroker-server/builds/141906662
using this travis file
https://github.com/volvo-cars/signalbroker-server/blob/f741be7ba7cdc0f058b8fd2558ead9ffabe4aba4/.travis.yml

Guess the reported problem does exist but it’s not really an issue for me. - somewhat embarrassing :slight_smile:

the arm32 (raspian or simiar) was a surprise to me; but given your observation it likely doesn’t work. Guess this should be added to some wish list. And in the multiarch topic.

for reference: arm32: https://travis-ci.com/volvo-cars/signalbroker-server/builds/141907715

many thanks.

I am happy to see the issue is gone by using docker container.
Yes, I think using the docker container is a good approach.

There is a way to run arm32 on arch: arm64 in Travis like this using dpkg --add-architecture and setarch command.

sudo dpkg --add-architecture armhf
sudo apt-get -yq install libc6:armhf

I remember I shared the way to a multiarch topic category’s thread in the past.

Here is the example.

I suppose Travis is already adding arch: arm32 feature to their wish list, as for example Drone CI already has it.
If you want to run your container on arm32 environment relatively easier, I would recommend to take a look at Drone CI.

Here is the example.

I’ll definitely dive in to those great advices. Many thanks!

sharing my findings, to build arm32/arm64 and amd64, i used dockerx which is well described in this blogpost

however i had to add an intermediate step to make it work like:

install: 
  - # Install QEMU
  - docker run --rm --privileged multiarch/qemu-user-static --reset -p yes

Build time is quite long, but i’m consider this multiarch feature as quite nice!

Erlang versions available for install are listed in https://docs.travis-ci.com/user/languages/erlang/#otprelease-versions.

21.1.4 is not in that list for arch64 but 21.2.3 is.
