test failure due to "uninitialized constant Concurrent::CAtomicReference"

The error you see is either because the C extension was not compiled or could not be loaded.

rake ci is task :ci => [:compile, 'spec:ci'].
So it should be compiled, and you should have a lib/concurrent-ruby/concurrent/concurrent_ruby_ext.so.

You can debug using RUBYOPT=-d or printing manually the error in try_load_c_extension.

[eregon]

As you can see the CI here doesn't have this problem, so it must be something specific to your environment.

[eregon]

Also this is expected if on purpose you don't use concurrent-ruby-ext: https://github.com/ruby-concurrency/concurrent-ruby#c-extensions-for-mri

But if you run bundle exec rake ci it should compile it for you anyway.

I confirm the test suite passes when the C extensions are installed. I often do not use bundle because it has a tendency to inflate the dependencies needed to build the package and run the test suite or sometimes outright fail in the containerized environment for some reason.

[eregon]

rake without bundle exec is pretty risky, it's likely it picks the wrong version of something and e.g. doesn't add the correct gems on $LOAD_PATH.

The test suite expects the C extension to be built and on $LOAD_PATH (via bundle exec, or in installed gems). That's good to ensure the C ext classes are used if the C ext is there.

GNU Guix builds things in a clean environment; it exposes only the dependencies specified for the package it builds in a Linux networkless namespace (container); so not using bundle in this context is not much risk.

[eregon]

so not using bundle in this context is not much risk.

Right, but it indeed misses some $LOAD_PATH entries for this case:
