Compilation failure in ruby 3.3.5

[CKolkey]

Hi! My team updated to ruby 3.3.5 recently and I encountered this issue when adding vernier to the Gemfile:

Installing vernier 1.2.1 with native extensions
Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

I uninstalled the ruby and reinstalled it, which produces a slightly different failure:

An error occurred while installing vernier (1.2.1), and Bundler cannot continue.

Platform is Macos 15.0, on an ARM processor (m2). Ruby is installed via mise. Ruby version is 3.3.5 Vernier version is 1.2.1 (latest at the time of this post).

Let me know if I can provide any other details to help figure out whats going on :)

Thanks!

Could you share the content of gem_make.out? That's where the actual error might be located.

[CKolkey]

Sadly not - I didn't include that originally because it's the same as whats printed above:

Uh, weird.

And if you clone the repo and try to compile from there? Still no explicit error?

Interestingly, when trying that with ruby 3.3.4, it produces the iostream error:

However, I was using vernier just fine on this computer a few days ago with 3.3.4. That was with the previous macos, but vernier failed to compile for 3.3.5 with that OS as well.

I don't think this is related to Ruby 3.3.5, seems more likely this is related to either Sequoia or the xcode command line tools.
