File mode specification error: (void-function first)

[akappen]

I just added the latest flymake-ruby from MELPA and it isn't working. When I open a ruby file ruby-mode is active but flymake-ruby is not. I do get some error output, the details follow. Let me know if you need anything else.

emacs
24.1.1

flymake-ruby
Version: 20121104.1859

flymake-easy
Version: 20121107.1109

I added the hooks to my init.el file:
(require 'flymake-ruby)
(add-hook 'ruby-mode-hook 'flymake-ruby-load)

When I open any ruby file, this error is logged to Messages:
File mode specification error: (void-function first)

If I execute flymake-ruby-load manually in a ruby buffer I get this in Messages:
flymake-easy-load: Symbol's function definition is void: first

flymake-ruby-executable is set to "ruby"

Running 'which ruby' with M-! returns the expected path to the ruby executable.

Thanks for the report!

Hmm. It looks like flymake-easy failed to explicitly require cl, and your Emacs set-up probably doesn't include anything else which loads that library. I've fixed it here: purcell/flymake-easy@37b86f1

While you wait for a new Melpa package of flymake-easy to build, you can M-x load-library RET cl RET, or put (require 'cl) in your emacs start-up file.

P.S. You can make Emacs generate a full stacktrace when errors occur, using M-x toggle-debug-on-error. The stacktraces can often be helpful when diagnosing problems.
