Firmware 3.9.2 compile warnings

Hi, everyone,

I'm attempting to compile firmware 3.9.2 using WSL on Windows 10.

My build environment:

  • OS: Windows 10 x64
  • WSL Version 2
  • WSL Distro: Ubuntu 20.04
  • Python 3.8
  • Ardunio IDE : 1.8.5
    Build env : 1.0.6
    Board : prusa_einsy_rambo
    Package name: PrusaResearch
    Board v. : 1.0.3
    Specific Lib: PrusaLibrary
  • git branch -a
    * MK3
    remotes/origin/HEAD -> origin/MK3

I've been following along with the instructions on the  GitHub page.

So far, I have:

  • Checked out the current branch (git checkout)
  • Renamed Firmware/variants/1_75mm_MK3S-EINSy10a-E3Dv6full.h to Configuration_prusa.h
  • Copied a copy of Configuration_prusa.h to the Firmware directory while also leaving a copy under Firmware/variants
  • Run PF-build.sh

Here is my output:

Start to build Prusa Firmware ...

Build done, please use Slic3rPE > 1.41.0 to upload the firmware

Does that exit code 1 mean that the build failed? Should I be worried about the invalid conversion and unused variable?

I'm hesitant to actually try out the firmware on the MK3S before understanding what this output means.

Thank you for any help you can provide!
