I am trying to get completion to work with company-clang. In particular, I would like to get completion candidates that are from header files that I provide with


When I look at the buffer clang-output. I can see the correct completion candidates.

However, in the code itself I only get the message

no completion found

Any idea what I am doing wrong? I follow the standard advice for setting up company.

My setup in .emacs

(require 'company)
(add-hook 'after-init-hook 'global-company-mode)
(require 'cc-mode)
(define-key c-mode-map  (kbd "<tab>") 'company-complete)
(define-key c++-mode-map (kbd "<tab>") 'company-complete)

Using M-x company-diag I get

    post your company and clang setup/config. otherwise there is nothing to inspect for errors. Also provide a link to the setup guide that you followed. – A_P Feb 15 at 22:48
