feat: Glibc version on OT2

[Neil-YL]

Overview

We’re trying to run Prefect natively on the OT-2 for workflow orchestration. However, we ran into compatibility issues because the robot’s glibc version is 2.25, while Prefect‘s dependencies require 2.28+.

Implementation details

For more details I have opened an issue on package request.

Design

Would it be possible to include a more recent version of glibc in future releases? Alternatively, is there a safe way for us to upgrade it on our side?

Acceptance criteria

No response

There's not really a safe way for you to upgrade the glibc version for the robot as a whole. What you could do is get an appropriately compiled glibc version, drop it in locally, and then run prefect with an LD_PRELOAD that points to it.

Compiling it appropriately will be a bit of a pain but you might be able to get it from a recent raspbian release that supports the rpi3b; glibc is nice and stable and so you could put it on a pi and copy it from /lib (or just flash it to an sd card and browse the sd card from a linux machine).
