Error building

[jtomasrl]

Im getting an error while building with a change in platformio.ini.

Specifically related to this line: extra_scripts = pre:resources/progname.py

https://github.com/djphazer/O_C-BenisphereSuite/blob/dd7a55a7416e91f8b511d21dfce671240630320f/software/o_c_REV/platformio.ini#L41C1-L41C42

By removing that line, Im able to build without any problems

Oof! Well that's not critical - it's a helper script that sets up the version string and filename. I've customized it to work for me on Windows... I'd still like to make sure it works in all cases.

What platform are you on? Can you provide the relevant error text?

sure, Im running Windows 11, PlatformIO Core, version 6.1.7, Python 3.9.7 and got this error

Ok, looks like the standard "tail" command is absent on a default Windows install. My solution will be to reimplement that in Python... should be an easy fix. Could be an easy Pull Request ;)

Finding myself stumped with Python at the moment, I'd recommend installing Git Bash or similar unix-tools package for Windows to cover this missing dependency. Besides, they're incredibly useful developer tools ;)
