Error(s) that match a know pattern in addition to what has been reported in the summary:

Is it still a thing on latest 2.5.0-r1? I see that musl does delivery this header in stage3. Is it reproducible?

Confirmed in v2.5.2

How can I help to fix this?

[Comment 6 Piotr Karbowski (RETIRED) 2023-07-08 17:30:39 UTC]

The PrusaSlicer depends on opencascade that does not build on musl and therefore is masked on all of those profiles, I do not think anyone will spend effort on it anytime soon given how difficult the entire codebase that dates back to slic3r project is.

tinderbox_musl has reproduced this issue with version 2.7.1 - Updating summary.
