Engine 1.10.0 linux-x86_64 prebuilt fails to load strategies on glibc older than 2.38 #730
Description
The engine 1.10.0 linux-x86_64 prebuilt requires glibc 2.38 or newer. On x86_64 systems with an older glibc, loading a strategy fails with an error such as undefined symbol: __isoc23_strtol.
This affects systems such as Debian 12, Ubuntu 22.04 and RHEL 9. The aarch64 prebuilt is unaffected. The 1.9.1 x86_64 prebuilt does not have this requirement.
A fix that lowers this glibc requirement again is planned for 1.11.0. No workaround has been verified for the affected 1.10.0 prebuilt.

Progress: the fix is now on
main(bd1fa2f, from #736). Linux release archives are now built with a digest-pinned Debian Bookworm toolchain, and before upload the release job unpacks the packed archive, then links and runs the native kernel host against its full shipped library.The corrected x86_64 archive ships with the next release (1.11.0). This issue stays open until that release is published and will be closed then. Until then, the 1.10.0 x86_64 prebuilt keeps the glibc 2.38 requirement described above; the
aarch64prebuilt and 1.9.1 are unaffected.luisleo526 commentedon Nov 8, 2026
Status update: a fix for the x86_64 prebuilt's glibc 2.38 requirement is in progress. It is planned for the 1.11.1 patch release, currently targeted for 2026-11-12, subject to review and CI. This issue will be closed with a link to the commit and pull request once the fix is on main.

Fixed in 1.12.0, the current release.
A clean-container check confirms it (run). It downloads the published x86_64 prebuilt archives, verifies them against their checksums, then builds and runs a sample strategy against each archive:
__isoc23_strtol/__isoc23_strtoll)A follow-up states the supported glibc floor for the prebuilt archives and makes the release check enforce it, so a later archive cannot require a newer glibc unnoticed. Closing this issue; if a 1.12.0 prebuilt fails to load on your system, please open a new issue with the distribution and the error.
