org-babel-execute:go crashes on Mac

org-babel-execute:go crashes on Mac

Morning,

recently I tried to use ob-go and ran immediately into:

org-babel-execute:go: Invalid function: (results (org-babel-eval (format "%s run %s \"%s\" %s" org-babel-go-command (mapconcat (quote identity) (org-babel-go-as-list flags) " ") (org-babel-process-file-name tmp-src-file) (mapconcat (function (lambda (a) (format "%S" (if (symbolp a) (let* (... ...) (if ... ... out)) a)))) (org-babel-go-as-list args) " ")) ""))

The strange thing is, that this only happens on my Mac. On my CentOS machine it works like a charm. Both machines run on Emacs 26.1b1 and org mode 9.1.9-65-g5e454. All packages are from Melpa and the machines share the same .emacs.

I have no idea how to get to the bottom of this phenomenon. Any hint or help would be appreciated very much.

Thank you
Mario

If you haven't already, I suggest checking that there isn't a difference in your Go setup, by working out the "go run ..." command that is being run below, and running that manually yourself.

Thank you for your answer.

My first assumption was - to be honest, still is - that the "go run …” is not executed at all because the call to “go run …”  is within an illegal elisp function. Am I wrong with my assumption?

Kind regards
Mario

P.S. Would have no idea how to work out what the outcome of the function is ;)

Perhaps I misunderstood the error message, but I thought perhaps it was
about code trying to represent the _result_ of the execution as an elisp
function.  But it is very difficult to tell!

I guess if I had this on my system (which I can't because I don't run on
a Mac), I'd use 'edebug-defun' on some of the functions involved in the
error message, in order to start understanding whether they are actually
being executed.

Best wishes,
