Here are my related configuration links for C/C++ development:
1. https://github.com/HongxuChen/dotfiles/blob/master/_emacs.d/config/init-cc-mode.el
General cc mode settings
2. https://github.com/HongxuChen/dotfiles/blob/master/_emacs.d/config/init-flymake.el
Add a flymake clang for single files
3. auto-complete-clang+yasnippet+autopair for editing assistance
4. fic-mode for highlight FIXME/TODO etc.
5. source code navigation:
(1) tag based: xgtags.el and xcscope.el(for header files that I never
modify since I cscope seems more accurate than xgtags).
(2) semantic based: cc-lookup(a simple script I write, based on
clang-lookup; it only looks for declaration/definition, no reference
support, no name refactoring support, and more improvements are
expected)
https://github.com/HongxuChen/cc-lookup
6. I also use directory local variables quite a lot

There are also several clang based tools for C/C++ coding:
1. https://github.com/Sarcasm/irony-mode
auto complete headers and code, syntax check; I cannot make the trigger
key right and there are some bugs for its plugins.
2. https://github.com/Golevka/emacs-clang-complete-async
a client-server version of auto-complete-completion; faster than
auto-complete-clang but many bugs
3. https://github.com/Andersbakken/rtags
Powerful tag system, there is a series video about it on Youtube, lookup
defintion/declaration/reference, rename refactoring, code completion;
but I don't know how to configure right:-(
4. company-mode
It's inferior to auto-complete and I don't use it.

Personally I don't like CEDET(together with ECB) since it's too Emacsy
and I come from Vim; the most important thing is that it sucks quite
often and the speed is not satisfying. But there seems a clang semantics
analysis on it and I hope it would make a hit.
