Hi Yupeng,

  It would be wise to subscribe to the mailing list if you would like
to get your posts replied to reliably. :)

  The GNU Global support is not yet magically 100% configured with one
step.  I'm still in the process of finding the integration paths, and
each path must be configured separately.

  If you want GNU Global to work with finding project includes, you
need to first make sure there is an EDE project active, like
ede-cpp-root.  You also need to enable Global via the EDE variable
`ede-locate-setup-options'.  Those two together will let Semantic find
any file in your project by simple name.

  To use Global to find symbols via semantic, you need to enable the
database backend via `semanticdb-enable-gnu-global-databases'.  Be
warned, however.  This database is only used for wide searches of root
symbols.  Smart completion doesn't do wide searches, it only searches
explicit lists of header files.  It would be useful for finding
explicit names for a Jump however.  I haven't tested this aspect much.

  As for ebrowse, it is useful for finding tags by name in a
directory.  Semantic still needs to parse everything.  Over time, the
ebrowse database becomes less useful as Semantic parses everything
normally, so I have stopped using it.

  Using Exuberant ctags can speed up parsing of C++, but it has some
subtle issues of its own.

  The semantic-ia-fast-jump bug you report sounds like something I had
fixed a several weeks ago.  I looked, and I don't think I've forgotten
to check any of my changes in.  If you can specify a precise way to
reproduce the bug, that would be helpful.  If there is no simple way
to reproduce the issue, you should use edebug-defun on
`semantic-ia--fast-jump-helper' to find out what is missing.

Good Luck
Eric
