How do I make flycheck find required file in emacs lisp?

I have 2 files in the same directory, say a.el and a-test.el.

a.el 

;; some functions
(provide 'a)

a-test.el 

(require 'a)

flycheck put a warning on the require in a-test.el says

Cannot open load files: a

How do I make flycheck find the required file in the same directory ?

Solution

  • Flycheck does not use load-path when checking Emacs Lisp files. Instead, it uses flycheck-emacs-lisp-load-path, which is empty by default.

    To make Flycheck use the current load-path, add the following to your init.el:

    (setq-default flycheck-emacs-lisp-load-path 'inherit)

    However, I recommend to use Cask in your projects, and then install flycheck-cask, to automatically use the right load path and package directory in Emacs Lisp projects.
