Examples does not compile on windows

[skoky]

I wanted to try examples on Windows, but there is dependency on nix crate. Can this be extended to be multiplaform inclkuding Windows? Thanks.

[ivmarkov]

The dependency on nix is not that big - it is just for scanning what network interfaces are in there. Perhaps with a little bit of an effort you can make it work on Windows and contribute a PR?

[skoky]

I tried. I replaced the nix with network-interfaces crate. The new crate does not provide is_active() to find active interfaces, but anyway it might be probably used.

When I start it like this cargo run --bin bridge --features astro-dnssd, it is ending like this:

[2025-11-14T21:03:52Z ERROR astro_dnssd::os::windows::register] Failed to register: 87

Can you advice what could Failed to register: 87 this mean? Thanks

[skoky]

I have to implement NetifDiag properly and convert Windows intetrfaces into the NetifInfo.

[skoky]

With full backtrace it looks like this

Having more loggign about the error

[2025-11-15T07:21:12Z INFO  rs_matter::transport::network::mdns::astro] Registering mDNS service: `_matterc._udp,_L3840,_S15,_V65521P32769,_CM` on port 5540

it looks like astro does not like the subtype. It registers the service with _matterc._udp but not with subtype. Not sure why. My branch with changes for reference https://github.com/skoky/rs-matter/commit/e0b291f7196547da19fc42bc9c3ec5a82789d324
Anyway, pairing does not work.

[ivmarkov]

You can temporarily remove some of the subtypes until it starts to work.

BTW - zeroconf not working for you on windows?

[skoky]

I am removig subtypes one by one and it does not work on Windows. Once I remove all of them the bridge starts, but pairing with Apple or Amazon does not work.

For the zeroconf on Windows I need to install some legacy apps to support Apple Bonjour. Its too legacy. Without the installation it fails on (exit code: 0xc0000135, STATUS_DLL_NOT_FOUND)
