Can't create virtual environment on ARMv7 Linux Musl

patrick-5546 commented 19 hours ago

This is what I get trying to create a virtual environment:

$ uv venv
  × Could not detect either glibc version nor musl libc version, at least one of which is required

Someone else also observed this issue here: https://github.com/astral-sh/uv/issues/1438, but it was not fixed by #1427

I used the installation script to install version 0.4.12

I wonder if we didn't port the fix when we added the code again?

My situation may be a bit of a unique case, as I am running Linux on an ARM processor on the DE1-SoC FPGA. Here is some more information about my system

Looks like there isn't a pre-built python binary that can run on my system, as the gnu versions require glibc >= 2.17, and there is no musl version

Update

As a workaround, I was able to compile Python 3.8.20 from source (albeit with some failing and skipped tests) and use that to create a virtual environment

uv venv --python /usr/local/bin/python3.8
