'Go 1.18 build error on Mac: "unix/syscall_darwin.1_13.go:25:3: //go:linkname must refer to declared function or variable"

I upgraded to Go 1.18 on Mac 12+.

'go build' fails with errors like:

Solution 1:[1]

This was caused by an old version of golang.org/x/sys (mentioned in this issue). Fix is to update with:

go get -u golang.org/x/sys

Solution 2:[2]

As documentation mentioned,

  1. The easiest way : run get -u golang.org/x/sys.
  2. Manual : git clone the repository to $GOPATH/src/golang.org/x/sys.

Solution 3:[3]

If go get -u golang.org/x/sys doesn't work, make sure to remove such line in your go.mod:

replace golang.org/x/sys => golang.org/x/sys v0.0.0-20200826173525-f9321e4c35a6
