32 bit macOS builds in 0.14.53 and forward

As of the latest Xcode/SDK it’s no longer possible to link 32 bit binaries;

jb@kvin:~/g/s/g/s/syncthing $ CGO_ENABLED=1 go run build.go -goarch 386 build
runtime/cgo

... lots more symbols here

I’ve changed the build server to not use CGO. As a result, at least, file system watching no longer works. DNS and HTTPS appears to work, but I wouldn’t be surprised if there’s hidden wonkyness (the resolver and CA bundle are things that have historically required CGO).

So if the next release doesn’t work well, y’all know why.

Well, all twelve of you on darwin-386, that is.

Yeah… Of course the users with usage reporting on is a fraction of the total, we’ve estimated ~ 25% before. And I don’t know the cause for those downloads, but the total number of downloads is off by about a magnitude compared to any relevant measure of the number of active users.

Hi,

Will 32 bit Windows be supported any more? One of my critical machines in my syncthing network still runs Windows XP

Thanks,

There is no change for Windows. Windows XP is not, specifically, supported. If it works for you anyway that’s good.
