I'm trying to install php-mode, but I keep encountering this error when I run M-x php-mode:

Symbol's function definition is void: cl-macroexpand-all

The error persists whether I install php-mode via MELPA or manually.

Environment: Emacs 24.3.94.1 (x86_64-apple-darwin13.4.0, NS apple-appkit-1265.21) of 2014-10-04 on builder10-9.porkrind.org

Why won't php-mode run? Note: I'm relatively new to Emacs, and inexperienced.

  • Same problem and same solution for cuda-mode in MELPA (version cuda-mode-20140704.1357). When trying to enable cuda-mode using M-x cuda-mode the error comes, but after using M-x load-library <RET> cl the command M-x cuda-mode runs without problems. – boclodoa Dec 19 '14 at 21:43
  • cuda-mode is on GitHub; consider opening an issue using its issue tracker. – Constantine Dec 19 '14 at 22:06
  • Here is the issue, thank you :) – boclodoa Dec 19 '14 at 22:33

The function cl-macroexpand-all has been obsoleted in Emacs 24.3; you are now supposed to use macroexpand-all instead, which is part of core Emacs, not the CL library.

The CL library defines cl-macroexpand-all as an alias for macroexpand-all, so in principle you could do

(require 'cl)

in your init file to fix the problem. However, the cl library itself is being deprecated, and using it is not recommended.

I think you should contact the authors of php-mode and tell them to use macroexpand-all.

It's bug #18845 in Emacs-24.4. To work around it, you need to add (require 'cl) somewhere before you load php-mode.
