semantic database

[kiani45]

Hi, all

I have a problem about semantic
I wanna use name completion for all information including STL
for example :

vector<int> v1 ;
v1.

then semantic will show me some accessable member and member functions in a
pop-up window
It works for my user defined type but I can't get information of STL
Can any one tell me what should I do??

I've checked this page
http://xtalk.msk.su/~ott/en/writings/emacs-devenv/EmacsCedet.html
try several ways, but it still doesn't work
Can any one help me ??

Thanks

here's my portion of .emacs file:

(require 'semantic-ia)  
(require 'semantic-gcc) 
(semantic-add-system-include "/usr/include/C++/4.2" 'c++-mode)
(semantic-add-system-include "~/MyProjects/C++/C++-3/HW2/header" 'c++-mode) 
(require 'semanticdb)
(global-semanticdb-minor-mode 1)
(require 'semanticdb-global)

If you type "M-x semantic-analyze-debug-assist" where it should show
the member functions, it will list the include files that it's parsed
for type definitions and the directories where it's searched for them.
 My guess is that <vector> is not loaded.

If it isn't, make sure the directories where it looks are all valid,
and it's in one of those.

In particular, I'm suspicious about the capital "C" in your
"/usr/include/C++/4.2"; in *nix the case matters, and I think it's
/usr/include/c++/<version> on most linux machines (it is on mine).

Hope that helps,

I have the same problem; I believe it's a bug.  I don't know semantec
at all, so someone else will have to address that.  It hasn't caused
me any problems yet.

For any devs listening: I'm using cedet-pre6 on ubuntu karmic, with gcc 4.4.
