PHP 8.3.29 on x86_64 target with glibc

[arthurpro]

I am trying to build PHP 8.3.29 using glibc for x86_64-linux-gnu target but it keeps failing in the same spot.
I was able to build 8.1, 8.2, 8.4, 8.5 without any problems but not 8.3...
I used the same config parameters for each build and a fresh container. I've spent over a day already trying to figure this out without any luck.

Can someone help with the following errors?

Would be good if you could send us your craft.yml or the build command with your environment variables dumped.

You can also try to check out this branch: #1006

[henderkes]

What's weird is that this shouldn't happen because we explicitly pass ac_php...avx512=no. It would make more sense if it came from a library.

[arthurpro]

@henderkes thanks for getting back to me. I can try that branch.

my craft.yml is identical for 8.2, 8.3 and 8.4, but it only fails on 8.3

I have a few environment vars set

BUILD_ROOT_PATH=/php/build
PKG_ROOT_PATH=/php/pkg
SPC_TARGET=x86_64-linux-gnu

do you need system vars as well?

[henderkes]

No, but if you could upload the log folder that would help. I can't reproduce the issue, it's working for me locally and in CI:

https://github.com/static-php/packages/actions/runs/21015398249/job/60419449066

(Ignore the arm64 failure, libsodium is still on a broken release)

[arthurpro]

It builds fine for me if I use SPC_TARGET=native-native-gnu, but with SPC_TARGET=x86_64-linux-gnu it fails.

It's important for me to build using generic x86_64-linux-gnu target, otherwise php binaries are not usable on some of my instances with older x86_64 CPU.

I've attached the log:

01-15-2026-11-19-42_files_list.zip

[henderkes]

Sorry, I had pinged the wrong workflow run: https://github.com/static-php/packages/actions/runs/21015398916/job/60419456414

It's running with x86_64-linux-gnu

[henderkes]

I see you're using prebuilt libraries, could you set that to false under download options? Your configure command correctly shows the avx512 vars as disabled.

(And delete your buildroot folder once, to force a rebuild)

[arthurpro]

got it! I will try that. thanks!
