Wheels are built as `manylinux_2_39_x86_64` and are incompatible with older ubuntu e.g. 20.04 and Google Colab (glibc too new)

[Vittorio-Caggiano]

Problem description

The current CI pipeline builds Linux wheels using GitHub’s ubuntu-latest runners (Ubuntu 24.04).
Since these runners ship with glibc 2.39, auditwheel automatically produces wheels tagged as manylinux_2_39_x86_64

However, Google Colab runs on Ubuntu 22.04 with glibc 2.35 and Ubuntu 20.04 with glibc 2.31
As a result, unbuntu 20.04 and 22.04 cannot install the published wheels due to incompatible glibc requirements.

Potential Cause

run: pixi run -e ${{ matrix.pixi-environment }} build_pypi_wheel
run: pixi run -e ${{ matrix.pixi-environment }} build_pypi_repair

Running auditwheel repair on Ubuntu 24.04 results in wheels tagged with the highest detected glibc: manylinux_2_39 instead of

• manylinux_2_28
• manylinux2014
  which have broader compatibility.

System information

Ubuntu 22.04 with glibc 2.35
Ubuntu 20.04 with glibc 2.31

CMake log

A quick follow up on this thread. I am running a GH CI with different architectures , OS versions, and package managers. It covers Ubuntu (x86_64 + ARM), macOS (Intel + ARM), and Windows, and install pymomentum-cpu via pip, uv, conda, and pixi where supported, using python 3.11. It looks like the library installs successfully with Pixi on the following platforms:

• x86_64 — Ubuntu 22.04
• x86_64 — Ubuntu 24.04
• arm64 — Ubuntu 24.04
• x86_64 — macOS 13
• arm64 — macOS 14

Not sure if this is helpful, but I wanted to share the additional context.
