MCU / Printerboard : STM32F103C8T6 blue pill

I’m trying to compile klipper for an STM32F103C8T6 (I know it’s old so I’m probably having problems compiling it)

I’ll leave it here in the meantime I’ll continue investigating

Sorry but I don’t know how to replace what it says in the forum…

The issue is caused by newer versions of GCC and newlibc that certain distributions started shipping, e.g. Ubuntu 24.04.

Either you switch back to an older / working Linux version, e.g. Debian Bookworm, or you wait some days until this is merged.

You can also pick this PR branch, but this requires some git understanding:

git fetch origin pull/6615/head:pr-6615
git checkout pr-6615

to pull these modification. And then to revert back at a later stage:

git checkout master
git branch -D pr-6615
