mini_racer not starting: `ZSt28__throw_bad_array_new_lengthv: symbol not found (LoadError)`

[morphine00]

Hi folks, I'm trying to use mini_racer in an environment in a Alpine LInux Docker container, with Ruby 2.7.2 and Rails 6.1.1. I understand this issue might be related to #63, but bear with me for a second.

When running bundle install, this is what I got:

Installing libv8-node 16.19.0.1 (x86_64-linux-musl)
Fetching mini_racer 0.6.4
Installing mini_racer 0.6.4 with native extensions
Updating files in vendor/cache
  * libv8-node-16.19.0.1-x86_64-linux-musl.gem
  * mini_racer-0.6.4.gem

The above messages led me to believe that there are in fact prebuilt libraries for this environment and everything would be okay, but when trying to start Rails afterwards... _ZSt28__throw_bad_array_new_lengthv: symbol not found (LoadError):

1: from /app/vendor/ruby/2.7.0/gems/mini_racer-0.6.4/lib/mini_racer.rb:14:in `<main>'
/app/vendor/ruby/2.7.0/gems/mini_racer-0.6.4/lib/mini_racer.rb:14:in `load': Error relocating /app/vendor/ruby/2.7.0/extensions/x86_64-linux-musl/2.7.0/mini_racer-0.6.4/mini_racer_extension.so: _ZSt28__throw_bad_array_new_lengthv: symbol not found (LoadError)

(I can provide the full stack trace if necessary).

Is this a case of mini_racer and/or libv8-node not working in Alpine, or should this setup be working and it's something else? Thanks.

[tisba]

First, Ruby 2.7 is EOL and not (actively) supported by mini_racer, see https://github.com/rubyjs/mini_racer#supported-ruby-versions--troubleshooting. mini_racer 0.6.4 is also not the latest version. Can you try bump one or both?

Also: Please make sure to run with the latest version of Rubygems (gem update --system) and bundler.

Alpine (musl libc) is unfortunately known for causing quite a few issues over the years 😞

Hey @niko-zvt 👋

I'm assuming you're using bundler? Providing Gemfile and Gemfile.lock might be helpful.

WARNING: The requested image's platform (linux/amd64) does not match the detected host platform (linux/arm64/v8) and no specific platform was requested

indicates that you haven't set linux/arm64 as a platform in your Gemfile (I'm guessing that arm64 is your platform). Please take a look at Supported Ruby Versions & Troubleshooting in the README.

@tisba
Yes, I use M2 Pro (arm64). This happens after the docker image has been successfully built, but at the time the container is launched.

Dockerfile —> Base image ruby:3-alpine (linux/amd64).

FROM jekyll/jekyll
RUN apk add --no-cache --virtual .build-deps \
        libxml2-dev \
        shadow \
        autoconf \
        g++ \
        make \
    && apk add --no-cache imagemagick-dev imagemagick
WORKDIR /srv/jekyll

ADD Gemfile /srv/jekyll/
RUN bundle lock --add-platform universal-darwin-8
RUN bundle install

I tried both with and without the --add-platform universal-darwin-8 flag.

Are you sure you run docker with --platform linux/amd64 to get Rosetta translation? You're on arm64, but jekyll/jekyll only provides linux/amd64 images.

Your example works on my M1 Pro (Sonoma 14.1) without any warning or errors.

[tisba]

Where do you get the Gemfile.lock from, @niko-zvt? Is that the lock file generated into the docker image?

When I use your Dockerfile 1:1 and diff it against the lockfile you've provided, I get the following diff. It is not surprising, as in the Dockerfile you added universal-darwin-8 as a platform. I build the image with: docker build --platform linux/amd64 ..

@tisba, Hello! Yes, I generate Gemfile.lock inside docker container.

1. In docker file FROM --platform=linux/amd64 jekyll/jekyll
2. I tried both with and without the --add-platform universal-darwin-8 flag.
3. I tried both with and without the --add-platform ruby flag.
4. I tried both with and without the --add-platform x86_64-linux flag.

Input:

docker run --rm -v "$PWD:/srv/jekyll/" -p "4000:4000" -it test-img bundler exec jekyll serve --watch --port=4000 —host=0.0.0.0

You also need to run the container with the correct platform docker run --platform linux/amd64 if you want to use Rosetta and x86 translation (I could have been more clear in #295 (comment)). This will remove the warning you're seeing.

But I'm getting the same error now, not sure why I missed that before, sorry.

It's not a general mini racer / alpine issue though. I used the following minimal example to check:

FROM ruby:3.2.2-alpine

RUN apk add musl-dev make g++

I can install and run mini_racer just fine with it (tested with a simple ruby -rmini_racer -e 'puts MiniRacer::Context.new.eval("41+1")'). bundle install from your Gemfile also works.

tl;dr

The jekyll image seems quite dated and is based on a 2 year old alpine 3.15. I'm not entirely sure what's going on, but since it's working with alpine 3.18 (what ruby:3.2.2-alpine is using), I suspect that this might be the cause.
