Failed to compile on Windows

[andylizi]

I tried this command on Windows:

cargo install josh-cli --locked --git https://github.com/josh-project/josh.git --tag r26.06.11

and got this error:

The previous version r26.05.08 compiles fine.

This seems to be introduced in d2d19dc. Would it be possible to gate josh compose for unix only, since the podman stuff probably won't work on Windows anyway.

Hi @andylizi thanks for reporting this.
We where so far not aware anyone is using Josh on Windows so we have no infrastructure setup to test on this platform.
I personally don't have any windows machine to test this on at all.
However, i think it does make sense to support "josh compose" on windows and also potentially podman, for remote building. So instead of gating we should actually fix this on windows.
We have quite a few topics we are working on right now though and very limited bandwidth. So I'm not sure in what timeframe we will be able to address this.
