emacs无法自动补齐?

[chp845]

我安装自动提示的插件：（配置为）
;;cedet
(add-to-list 'load-path
"/usr/share/emacs/cedet-1.1/common")
(load-file "/usr/share/emacs/cedet-1.1/common/cedet.el")
;(global-ede-mode 1) ; Enable the Project management system
;(semantic-load-enable-code-helpers) ; Enable prototype help and smart completion
;(global-srecode-minor-mode 1) ; Enable template insertion menu
;;设置检索范围
;(setq semanticdb-project-roots
;(list
;(expand-file-name "/")));;可以设置为项目的顶级目录
;;绑定按键,ctr+tab,以下三种,任意选择一个,我喜欢第二个
;;(global-set-key [(control tab)] 'senator-complete-symbol);
;;(global-set-key [(control tab)] ' senator-completion-menu-popup)
(global-set-key [(control tab)] 'semantic-ia-complete-symbol-menu)

操作：
打开emacs后，file->openfile 打开一个c++ cpp文件，但是我输入的时候按Control tab 没有自动补齐,出现下面记录！

配置一下auto-complete,不过emacs自动补全很废品，建议c++用qtcreator
