wormhole-william @1.0.6: //go:linkname must refer to declared function or variable

I'm not sure if this is a bug or an issue on my system.

I'm not sure how to debug this, if anyone could provide me with a hint or 2 I'd be most grateful.

Please remember to fill in the Port field and Cc the maintainer.

Sorry I missed that, thanks for the tidying up

The errors in the log start with:

:info:build # github.com/fatih/color/vendor/golang.org/x/sys/unix
:info:build ../../fatih/color/vendor/golang.org/x/sys/unix/syscall_darwin.1_13.go:25:3: //go:linkname must refer to declared function or variable

It's not just your system. We ​see it on a build machine too. I think something must have changed in the go ecosystem since wormhole-william was updated to 1.0.6 but there is no newer version of wormhole-william that we could update to yet. I guess the problem should be reported to the developer of wormhole-william so they can update whatever needs to be updated.

​This post suggests go 1.18 and later are what caused the problem; fatih/color's vendored x/sys dependency would need to be updated to a newer version that is compatible with go 1.18 and later.

This port uses fatih/color 1.10.0. The ​release notes for fatih/color 1.15.0 say x/sys was updated to 0.6.0 in that version so that may resolve the problem, however x/sys 0.9.0 is available today; I don't know in which version of x/sys the go 1.18 incompatibility was resolved. And I don't know if we can just update wormhole-william's fatih/color dependency without disturbing the rest of wormhole-william; I'm not familiar with how go works. Herby has done a lot of work on the go ports in MacPorts so I'm Cc'ing him for possible input.

wormhole-william does not list fatih/color in ​its dependencies so I guess it is an indirect dependency but I don't know of what.

I saw those errors as well and wondered if they might not be related, but the logs keep going after. I tried sudoing to macports and running go build myself, I put the log of how that went in the description. According to that attempt, I suspect a permissions error when attempting to create ~/Library/Caches. go build is being run as macports but tries to create a new directory in the user's homedir is my read on things.

For the record I ran go get github.com/psanford/wormhole-william and go install github.com/psanford/wormhole-william and it's running just fine on my system today
