Unable to make it work

[c02y]

I followed your instruction:

  (eval-after-load 'flycheck
	'(add-hook 'flycheck-mode-hook #'flycheck-checkpatch-setup))

But flycheck-checkpatch doesn't work at all.

And M-x flycheck-verify-checker checkpatch or M-x flycheck-select-checker checkpatch tells me this:

Syntax checker in buffer test.c in c-mode:

  checkpatch
    - major mode: `c-mode' supported
    - may enable: yes
    - predicate:  nil
    - executable: Found at /home/user/.local/bin/checkpatch.pl

Flycheck cannot use this syntax checker for this buffer.

Flycheck Mode is enabled. Use C-u C-c ! x to enable disabled checkers.
