linux-x64 prebuilt release for openab-0.8.3-beta.6 requires GLIBC_2.39 and fails on Debian 12

[jacklau1993]

Summary

The official openab-0.8.3-beta.6-linux-x64.tar.gz prebuilt binary fails to start on Debian 12 because it requires GLIBC_2.39.

Why this looks like a release packaging / compatibility bug

• The docs position native binaries as available for temporary local development and debugging (docs/local-dev.md), but I could not find a documented minimum glibc requirement.
• On the same host, building openab from source at tag openab-0.8.3-beta.6 works fine and the resulting binary runs normally.
• That suggests the runtime incompatibility comes from how the official Linux x64 release artifact is built, not from the code itself.

Environment

• Host: Debian 12
• ldd --version: Debian GLIBC 2.36-9+deb12u13
• Architecture: x86_64
• Release artifact: openab-0.8.3-beta.6-linux-x64.tar.gz

Repro

curl -fsSL https://github.com/openabdev/openab/releases/download/openab-0.8.3-beta.6/openab-0.8.3-beta.6-linux-x64.tar.gz -o /tmp/openab-0.8.3-beta.6-linux-x64.tar.gz
tar -xzf /tmp/openab-0.8.3-beta.6-linux-x64.tar.gz -C /tmp
/tmp/openab --help

Actual result

/tmp/openab: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.39` not found (required by /tmp/openab)

Expected result

The official Linux x64 release binary should either:

1. run on a reasonably common glibc baseline such as Debian 12 / glibc 2.36, or
2. document the required minimum glibc version clearly in the release / docs.

Additional data

Building from source on the same machine at tag openab-0.8.3-beta.6 succeeds, and the built binary runs normally.

Possible fix directions

• build Linux x64 release artifacts on an older glibc baseline
• publish a musl-linked Linux artifact
• or clearly document the minimum glibc requirement for official native binaries

Hi @jacklau1993,

Confirmed — the Linux x64 release artifact is built on ubuntu-latest (currently Ubuntu 24.04, glibc 2.39) in .github/workflows/build-binaries.yml:19. Any host with glibc < 2.39 (including Debian 12 with glibc 2.36) will fail with the error you reported. Building from source on the same host works because it links against the local glibc.

• No existing issues or PRs addressing this.

Fix directions: pin the Linux build runner to an older Ubuntu (e.g. ubuntu-22.04, glibc 2.35) or add a musl-linked (x86_64-unknown-linux-musl) artifact. A PR to fix this is welcome — feel free to open one if you are interested.
