Due to a bug in Go (golang/go#51778), cmd/go doesn't warn about your Go version being older than the go.mod's declared Go version in that case that package loading fails before the build starts, such as when you use packages that are only in the current version of Go, like our use of net/netip. This change works around that Go bug by adding build tags and a pre-Go1.18-only file that will cause Go 1.17 and earlier to fail like: $ ~/sdk/go1.17/bin/go install ./cmd/tailscaled # tailscale.com/cmd/tailscaled ./required_version.go:11:2: undefined: you_need_Go_1_18_to_compile_Tailscale note: module requires Go 1.18 Change-Id: I39f5820de646703e19dde448dd86a7022252f75c Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>
