NOTE: I recommend that you use the flycheck. Because, you can run the checker more than one. Of course, including cppcheck.

flymake-cppcheck.el

Cppcheck for Emacs with flymake-mode.

To use Cppcheck with Emacs, you will need Cppcheck installed.

You should be able to run

$ cppcheck

and, you'll also need to install flymake-easy.

Usage

You'll need to add the directory containing flymake-cppcheck.el to your load-path.

If not, also add to your config

Add to your Emacs config

(require 'flymake-cppcheck)
(add-hook 'c-mode-hook 'flymake-cppcheck-load)
(add-hook 'c++-mode-hook 'flymake-cppcheck-load)
