load arduino-mode error

[stardiviner]

When I load arduino-mode with use-package (use-package arduino-mode). I got this error:

+BEGIN_EXAMPLE

(invalid-function (append '("HIGH" "LOW" "INPUT" "OUTPUT" "INPUT_PULLUP" "LED_BUILTIN" "true" "false") (c-get-lang-constant 'c-constant-kwds '(cc-langs))))
signal(invalid-function ((append '("HIGH" "LOW" "INPUT" "OUTPUT" "INPUT_PULLUP" "LED_BUILTIN" "true" "false") (c-get-lang-constant 'c-constant-kwds '(cc-langs)))))

ad-Advice-require(# arduino-mode nil noerror)
apply(ad-Advice-require # (arduino-mode nil noerror))
require(arduino-mode nil noerror)
(not (require 'arduino-mode nil 'noerror))

+END_EXAMPLE

When I use (require 'arduino-mode), got this error:

+BEGIN_EXAMPLE

c-get-lang-constant: ‘c-matchers-2’ got no (prior) value in arduino-mode (might be a cyclic reference)

+END_EXAMPLE

My Emacs version: 25.1.50.5

Thanks report this. There's probably some changes in cc-mode in Emacs 25 that I need to account for. I'll try to look into it in the next couple of days.

@bookest Thanks.

Just as a conflicting data point, I am not able to reproduce this error with the latest arduino-mode from melpa, arduino 1.8, arduino-mk 1.5-2 from ubuntu packages, and emacs 25.1. Everything seems to work fine for me.

• latest arduino-mode
• Emacs version: 25.1.1
  Still get error in buffer *Messages*:

emacs-php/php-mode#243 looks related to that problem.

Seems solved after updated and in new version Emacs.
