Emacs中的C++程序智能提示是个不容易的活。我使用的是auto-completion插件。该插件依赖clang编译器进行代码分析，当然还依赖其他的emacs插件。下面是我的Emacs配置文件。

;;------------------------------------------------------------------------------;; auto complete;;------------------------------------------------------------------------------;;(load-file (expand-file-name "/opt/emacs_plugins/c++/auto-complete-1.3.1");;(add-to-list 'load-path "/opt");;(require 'auto-complete-config);;(add-to-list 'ac-dictionary-directories "/opt/ac-dict");;(ac-config-default)(add-to-list 'load-path "/opt/emacs_plugins/c++/auto-complete-1.3.1")(require 'auto-complete-config)(add-to-list 'ac-dictionary-directories "/opt/ac-dict");;------------------------------------------------------------------------------;; yasnippet;;------------------------------------------------------------------------------;;sudo apt-get install yasnippet(add-to-list 'load-path "/opt/emacs_plugins/c++")(add-to-list 'ac-dictionary-directories "/opt/emacs_plugins/c++")(require 'yasnippet-bundle);;------------------------------------------------------------------------------;; clang for c++;;------------------------------------------------------------------------------(load-file "/opt/emacs_plugins/c++/brianjcj-auto-complete-clang-9db79f4/auto-complete-clang.el")(require 'auto-complete-clang)(setq ac-auto-start nil)(setq ac-quick-help-delay 0.5)(define-key ac-mode-map  [(control tab)] 'auto-complete)(defun my-ac-config ()  (setq ac-clang-flags (split-string "-I/usr/local/gcc-4.6.1/include/c++/4.6.1 -I/usr/src/boost_1_47_0"))  (setq-default ac-sources '(ac-source-abbrev ac-source-dictionary ac-source-words-in-same-mode-buffers))  (add-hook 'emacs-lisp-mode-hook 'ac-emacs-lisp-mode-setup)  ;;(add-hook 'c-mode-common-hook 'ac-cc-mode-setup)  (add-hook 'ruby-mode-hook 'ac-ruby-mode-setup)  (add-hook 'css-mode-hook 'ac-css-mode-setup)  (add-hook 'auto-complete-mode-hook 'ac-common-setup)  (global-auto-complete-mode t))(defun my-ac-cc-mode-setup ()  (setq ac-sources (append '(ac-source-clang ac-source-yasnippet) ac-sources)))(add-hook 'c-mode-common-hook 'my-ac-cc-mode-setup);; ac-source-gtags(my-ac-config)

需要提示的时候，就按下Ctrl+Tab键。
