I use this do some experiment for c++ projects in my emacs 24.3 and latest cedet in "https://git.code.sf.net/p/cedet/git" (also in emacs 23.1 and stable cedet1.1). I am quite satisfied with it except for one small "jump to function implement" issue in "semantic-analyze-proto-impl-toggle". alex, could you help me to check this issue?
my project is very simple(only 2 files):

  1. head file "y.hpp" in dir "~/emacs/test/zz1/"

    class y{
    public:
    int y1(int);//error here! semantic can't found implement in y.cpp
    };

  2. implement file "y.cpp" in dir "~/emacs/test/zz2/"

    #include "y.hpp"
    int y::y1(int b) // semantic can found definition use "semantic-ia-fast-jump" in y.hpp
    {
    return 0;
    }
    my cedet config is based on alex oot 's "minimial-cedet-config.el"([https://gist.github.com/alexott/3930120][1]) and only add following two lines:

(semantic-add-system-include "~/emacs/test/zz1/" 'c++-mode)

(semantic-add-system-include "~/emacs/test/zz2/" 'c++-mode)

i checked my semantic db cache and found all db file is create correctly,
this is info in cache db for y.hpp in zz1:
;; Object zz1/
;; SEMANTICDB Tags save file
(semanticdb-project-database-file "zz1/"
:tables (list
(semanticdb-table "y.hpp"
:major-mode 'c++-mode

(:members
( ("public" label nil (reparse-symbol classsubparts) [10 17])
("y1" function
(:prototype-flag t
:arguments
( ("" variable (:type "int") (reparse-symbol arg-sub-list) [27 31]))
:type "int")
(reparse-symbol classsubparts) [20 32]))
:type "class")
nil [1 35]))
:file "y.hpp"

)
)
:file "!home!zzhao010!emacs!test!zz1!semantic.cache"
:semantic-tag-version "2.0"
:semanticdb-version "2.2"
)

this is info in cache db for y.cpp in zz2:
