Versions

dso, version 0.13.2

The future is here ?

[grst]

only if it works 🙈
But I have the feeling this could be a suitable task for the bots.

[DSchreyer]

I see how this is going :D

[grst]

Ok, summary:

• copilot was not able to fix that specific error even in multiple iterations
• the error is not the only issue. Different things would need to be fixed to make DSO work on Windows

I don't want to invest the time for that at the moment as we don't have a use-case for it internally.
So basically I'd lean to say "Windows is not supported" and recommend Windows users to work with WSL instead.

[DSchreyer]

understandable! I will see if it is worth to look into
