Most changes to Python require a NEWS entry. Add one using the blurb_it web app or the blurb command-line tool.

If this change has little impact on Python users, wait for a maintainer to apply the skip news label instead.

I was under the impression that gh-126465 fixed the JIT failures, and we're waiting on an upstream fix. Do we need this?

[brandtbucher]

This doesn't seem to fix the issue.

Oh! Awesome, so this probably boils down to a version/path problem...

As a sidenote, I also saw actions/runner-images#10917, which may fix this issue as it removes the newest version of xcode. However, it doesn't hurt to explicitly state SDKROOT anyway. What's interesting is that when I was building LLVM from source awhile ago, I also had to specify SDKROOT for newer LLVM to find headers.

Thanks so much!

Thanks! One suggestion:

[brandtbucher]

Since we're doing this on line 134 too, maybe just remove both and put export SDKROOT="$(xcrun --show-sdk-path)" before the ./configure step?

Thanks!
