The CI failure on macOS x86_64 seems to be related to the following warning:

warning: deployment target in MACOSX_DEPLOYMENT_TARGET was set to 10.10, but the minimum supported by `rustc` is 10.12

Note in the Qiskit documentation, it is stated that macOS 10.12 or higher is required on this architecture. This architecture has also been demoted to "Tier 2" support with the most recent Qiskit release.

Export the environment variable MACOSX_DEPLOYMENT_TARGET to 10.12 on macOS, that's fine: macOS 10.14 is the minimum version supported by julia anyway

I've been playing with this variable, but so far I haven't found a version that actually fixes the link error yet. So far I have tried up to MACOSX_DEPLOYMENT_TARGET=15.

That's probably not the issue then, aarch64-darwin uses the 11.0 SDK. But upgrading to the SDK 11.0 may help, the error is https://buildkite.com/julialang/yggdrasil/builds/26573#019bb42d-b578-48de-85b9-6d071cb36850/L1765

for how to upgrade the SDK to v11.0

Note that the function require_macos_sdk already sets the environment variable:

The key part of the CI failure appears to be

and they continue from there.

giordano · 2026-01-15T00:27:36Z

The key part of the CI failure appears to be

More specifically:

[16:44:30] error: failed to write /tmp/rustcN3Y7pA/lib.rmeta: No space left on device (os error 28)

We have a tiny /tmp partition. Whatever is being written there should be redirected somewhere else (for example ${WOKRSPACE}/srcdir/tmp).

Also, when I run the build now locally, I see many I/O errors

Ah, unfortunately that's expected if you're using Docker (e.g. on macOS)

giordano · 2026-01-15T00:31:22Z

The problem with the tmp partition is probably the same as #10590 (comment) and #10853. Edit: no, that's a different issue, that was about location of CARGO_HOME, which is under /opt (also tiny), the present issue is about something writing to /tmp.

giordano · 2026-01-15T00:39:41Z

For /tmp, something like

Yggdrasil/P/pixi/build_tarballs.jl

Lines 14 to 16 in 4e5303d

    
           # not enough space in /tmp 
        
           export TMPDIR=$WORKSPACE/tmp 
        
           mkdir $TMPDIR

may be sufficient.

giordano · 2026-01-15T17:42:18Z

New error, that's progress!

error: failed to unpack package `windows-sys v0.45.0`\n\nCaused by:\n  failed to unpack entry at `windows-sys-0.45.0/src/Windows/Win32/System/Environment/mod.rs`\n\nCaused by:\n  failed to unpack `/opt/x86_64-linux-musl/registry/src/index.crates.io-1949cf8c6b5b557f/windows-sys-0.45.0/src/Windows/Win32/System/Environment/mod.rs`\n\nCaused by:\n  failed to unpack `windows-sys-0.45.0/src/Windows/Win32/System/Environment/mod.rs` into `/opt/x86_64-linux-musl/registry/src/index.crates.io-1949cf8c6b5b557f/windows-sys-0.45.0/src/Windows/Win32/System/Environment/mod.rs`\n\nCaused by:\n  No space left on device (os error 28)

Ok, now that's #10590 (comment) and #10853! 😁

The x86_64 musl build succeeds, but the others fail.

[19:43:10] error: failed to run custom build command for `rayon-core v1.13.0`
[19:43:10] 
[19:43:10] Caused by:
[19:43:10]   could not execute process `/workspace/srcdir/qiskit/target/release/build/rayon-core-9598dc783be16b44/build-script-build` (never executed)
[19:43:10] 
[19:43:10] Caused by:
[19:43:10]   Exec format error (os error 8)

It seems that after setting CARGO_HOME, this is now built with the incorrect target on other platforms.

fingolfin · 2026-01-15T21:30:01Z

Just based on the message you posted, that sounds as if the build procedure builds n executable for the target OS (via cross compiler) and then tries to run it on the host, which won't work unless host and target match (i.e., musl x86_64).

If that executable really needs to be run on the build host, it needs to be built with the host compiler instead.

This reverts commit 4da7fc0.

Two reasons, really: 1. It's proving difficult to build 2. It's been demoted by the Qiskit developers to the status of a Tier 2 platform.

fingolfin · 2026-01-16T23:26:45Z

Seems to pass CI now, congrats (but is still marked as a draft)

garrison · 2026-01-17T03:14:01Z

Seems to pass CI now

I reverted 4da7fc0 and dropped support for macOS x86_64 in 31457cc. So yes, CI passes, but I haven't made real progress 🙂. Even so, this may be worth merging in its current form, especially since the relevant platform no longer has full (Tier 1) support upstream.
