使用emacs-clang-complete-async时出现问题

Question

我一直试图设置emacs-clang-complete-async。我已经编译了clang-complete二进制文件，并且没有在emacs中收到任何错误，但自动完成功能似乎无法正常工作。

这就是我在.emacs中所拥有的：

(add-to-list 'load-path "~/.emacs.d/")
(require 'auto-complete-clang-async)

(defun ac-cc-mode-setup ()
  (setq ac-clang-complete-executable "~/.emacs.d/clang-complete")
  (setq ac-sources '(ac-source-clang-async))
  (ac-clang-launch-completion-process)
)
(defun ac-common-setup ()
  ())
(defun my-ac-config ()
  (add-hook 'c-mode-common-hook 'ac-cc-mode-setup)
  (add-hook 'auto-complete-mode-hook 'ac-common-setup)
  (global-auto-complete-mode t))

(my-ac-config)
