    <p>I use emacs 23.1.1 on X86_64-pc-gnu-linux (ubuntu 10.04) and follow the famous link <a href="http://alexott.net/en/writings/emacs-devenv/EmacsCedet.html" rel="nofollow">http://alexott.net/en/writings/emacs-devenv/EmacsCedet.html</a> to add all config to .emacs. But it can NOT do even basic job. There must be sth wrong with my setup or configue.</p> <p>If I try to let it display the member function, it NOT be able to find. [ auto complete use clang as parser. So what the parser semantic uses? ]</p> <pre><code>;; Load CEDET (load-file "~/backup/cedet-trunk/common/cedet.el") (global-ede-mode 1) ;(semantic-load-enable-code-helpers) (semantic-load-enable-excessive-code-helpers) ;(semantic-load-enable-semantic-debugging-helpers) (global-srecode-minor-mode 1) (global-semantic-tag-folding-mode 1) (require 'semantic-tag-folding) (global-semantic-idle-scheduler-mode 1) (global-semantic-idle-completions-mode 1) (global-semantic-idle-summary-mode 1) (global-semantic-idle-completions-mode) (require 'semantic-ia) (require 'eassist) (require 'semantic-gcc) (require 'semanticdb-global) (semanticdb-enable-gnu-global-databases 'c-mode) (semanticdb-enable-gnu-global-databases 'c++-mode) (setq qt4-base-dir "/usr/include/qt4") (setq qt4-gui-dir (concat qt4-base-dir "/QtGui")) (setq qt4-core-dir (concat qt4-base-dir "/QtCore")) (semantic-add-system-include qt4-base-dir 'c++-mode) (semantic-add-system-include qt4-gui-dir 'c++-mode) (semantic-add-system-include qt4-core-dir 'c++-mode) (add-to-list 'auto-mode-alist (cons qt4-base-dir 'c++-mode)) (add-to-list 'semantic-lex-c-preprocessor-symbol-file (concat qt4-base-dir "/Qt/qconfig.h")) (add-to-list 'semantic-lex-c-preprocessor-symbol-file (concat qt4-base-dir "/Qt/qconfig-large.h")) (add-to-list 'semantic-lex-c-preprocessor-symbol-file (concat qt4-base-dir "/Qt/qglobal.h")) (defun my-cedet-hook () (local-set-key [(control return)] 'semantic-ia-complete-symbol-menu) (local-set-key "\C-c?"

    1. COGiven that they don't have a cedet-users mailing list, I would suggest trying [cedet-devel](http://sourceforge.net/mailarchive/forum.php?forum_name=cedet-devel) as well. (I am trying to get started on CEDET as well, it's been rough going thus far)

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
