undefined: stream - Issue with Mac OS M2

[LordMoMA]

On Linux Ubuntu, it does not have the below problem, but OS M2 has:

# github.com/rjeczalik/notify
../../../pkg/mod/github.com/rjeczalik/notify@v0.9.2/watcher_fsevents.go:49:11: undefined: stream
../../../pkg/mod/github.com/rjeczalik/notify@v0.9.2/watcher_fsevents.go:200:13: undefined: newStream

stream is defined at

notify/watcher_fsevents_cgo.go

Line 117 in 8c8ecfe

type stream struct {

Make sure you build with cgo and the other expected flags I guess

If I built with CGO_ENABLED=1, it generates other problems, and the pod could not be spun up

CGO_ENABLED=1 go build -ldflags "-s -w" ./cmd/crypto-tron

CGO_ENABLED=1 go build -ldflags "-s -w" ./cmd/crypto-tron

I think most of these warnings were fixed in #215 make sure you using the latest code
Anyway, I don't see why deprecation warnings failed the build , you sure that's the whole relevant output?

[LordMoMA]

problem solved by upgrading to the latest version and set CGO_ENABLED=0, why we don't need CGO here?

[ReallyLiri]

If you build without cgo you'd actually be using kqueue and not fsevents.
fsevents condition is //go:build darwin && !kqueue && cgo
kqueue condition is //go:build (darwin && kqueue) || (darwin && !cgo) || ...
kqueue might very well suit your needs, depending on your usage of this library.

thank you for the knowledge here ❤️
