Before submitting an issue, please be sure to

• Read the contributing instructions
• Update to the latest Gem version (run bundle update github-pages)

This issue affects

• The site generated by GitHub Pages
• Building sites locally

The GitHub Pages Gem is intended to help users replicate the GitHub Pages build environment locally. If your issue affects both the hosted version and the version previewed locally, you may be better suited reporting seeking support in other forums.

What did you do (e.g., steps to reproduce)

1. enable the jemoji plugin in _config.yml
2. make image_alpine
3. SITE=/path/to/site make server

What did you expect to happen?

a running local server

What happened instead?

build failed because the nokogiri gem couldn't access the shared library ld-linux-aarch64.so.1

Additional information

• Nokogiri depends on glibc

  • Linux aarch64-linux (req: glibc >= 2.29) including musl/Alpine
    - Nokogiri docs on supported platforms

• From the Nokogiri docs on musl having error loading shared library

  Musl-based systems like Alpine may not have a glibc-compatible library installed,
  leading to problems running the precompiled native gems.

• and also the solution

  Install the glibc compatibility layer:
  apk add gcompat

NB this does not affect the image built from Dockerfile.alpine@e9d9768.

However I feel it would be nice to include the required library in the image because

• emoji are used quite often while blogging today
• most users of the Docker images are likely to prefer the Alpine one for local development thanks to it's smaller size on disk
