Don't support the latest flymake

[xuchunyang]

I encounter an error when I type M-x helm-flymake, here is the backtrace

Debugger entered--Lisp error: (void-variable flymake-err-info)

I built my Emacs from git repo recently. The variable flymake-err-info was removed a few months ago in emacs-mirror/emacs@94a88c1. I think I can fix this issue when I have time and get familiar with flymake.

Any update on this? :)

[xuchunyang]

Nope.

But I just tried helm-flymake again using Emacs 27.1, and it fails because of another issue:

helm-M-x-execute-command: Symbol's value as variable is void: flymake-err-info

I also got some byte compiler warnings during M-x package-install

In toplevel form:
helm-flymake.el:85:30:Warning: Package cl is deprecated

In helm-flymake-get-err-list:
helm-flymake.el:92:25:Warning: reference to free variable ‘flymake-err-info’

In helm-flymake-get-candidate:
helm-flymake.el:106:6:Warning: ‘mapcar’ called for effect; use ‘mapc’ or
‘dolist’ instead

In end of data:
helm-flymake.el:187:1:Warning: the following functions are not known to be
defined: flymake-ler-line, flymake-ler-type, flymake-ler-text

I am not sure if helm-flymake works with latest flymake.

[manuel-uberti]

Yes, there is no flymake-err-info any more, the API has changed quite a lot.

Hi guys, it works with the latest flymake now. Enjoy it.
