I couldn't get anywhere because the build kept failing. Now, over a year later and upgrading to Sonoma on my M1 MacBook Air, the build still fails at some point. If this is the right group (I've forgotten), I'll post the stdout from my last try, but after the first fail (so it still fails, but the output isn't as large).

From the suggestions at the right to the post input, I posted about my previous failures to the sub-group too.

This is an appropriate place to post, though as John notes in your previous thread it seems you were able to get the compiler building, you were just encountering some test failures.

But so many changes have happened (on both sides) since then. It looks like it's currently a compiler issue:

Is this with a fresh clone of all the repos? If not, have you run utils/update-checkout (and/or re-cloned everything) to make sure things are all up-to-date from a year ago?

5

I kept all the old files and ran utils/update-checkout on top of them. Should I just trash it all then re-start/download?

I'm using just-installed Sonoma and Xcode 15. Am I supposed to use an older compiler?

6

As far as I know that shouldn’t be necessary if update-checkout succeeded for all repos, but it can’t hurt to start from a clean slate. I’ve successfully built on Sonoma with Xcode 15 from top-of-tree just today.

7

Took over 2 years to notice that the optional "--xctest " build argument is Linux-only. Compiled just fine with the default Sonoma/Xcode-15 setup. Still have to try proper tests and the Xcode project version.

Now running the tests, they ended with:

I would recommend you to update to the latest main branch of the swift compiler, run the update-checkout, and then run build-script. These instructions can be found on GettingStarted.md

cd swift
git checkout main
git pull origin main
utils/update-checkout --clone ...
utils/build-script ...

Let us know where you fail and we would be able to help you

Surprisingly, I built the compiler in release mode and it failed 1 test: python_lint.swift

swift/utils/build-script -R -t

Tests on main don't always pass in all configurations, as the main branch reflects current work in progress, and PR testing runs on PR branches but not on the main branch itself.

Even when with a given PR 100% of all tests pass, by the time it's merged a different combination of merges may lead to a test regression, and by that time the combination of commits from all projects participating in a build and test run (compiler, LLVM, core libraries, the driver, the syntax library etc) has changed. Besides, to merge a PR on main you only need smoke tests to pass, not the whole test suite. Integration tests usually run only for full toolchain builds.

If you want a higher chance of all of the tests passing, I recommend trying the release/* branches, which move more slowly, especially the already released 5.8 branch. There's still ongoing work on 5.9 patch releases though.

Overall, if you're looking to contribute there's no need to make 100% of all the tests pass locally on your machine. Just make sure that tests don't regress after making your changes, and you'll most likely get much better test coverage on CI when you submit a PR.
