Yeah, this is what I was afraid of. And the sentiment I've run into generally is that CGO is evil and bad and should be avoided at all costs 😕

Looking at the diff, I wonder if the conditional is needed at all. I think you can simply set CGO_ENABLED=1 in podman-remote-darwin since that target will never ever be used for anything but darwin. In other words, I question if CGO_ENABLED=whatever has any impact based on if we're cross-compiling or not.

In case it helps you cycle faster: You can temporarily trick CI into only running certain tasks by making them skip: $CI == $CI. You'll need to fight with the YAML anchors/aliases a bit. But this will let you (for example) only run the "OSX Cross" and "Alt Arch. Cross" tasks instead of waiting for everything else.

Maybe it doesn't help, but there is a native mDNS package available: https://pkg.go.dev/github.com/hashicorp/mdns

S'pose a call to it would need to be grafted in every single damn place a name-lookup is made 😕

But then at least CGO isn't needed 😁

@ashley-cui Can we get a new brew build done of podman for MAC?

[zeha]
