使用emacs语义与ede和company-mode来完成和导航

Question

I followed http://tuhdo.github.io/c-ide.html#orgheadline33 tutorial to build ac/c++ IDE using emacs.

However I have problems using semantic to complete with company-mode and navigate. The thing is that when I try to tell semantic where is other library or codes is using semantic-add-system-include, it only works with c++ includes.

If I add (semantic-add-system-include "~/mylib") , semantic won't parse the files in ~/mylib and so company won't work. But if I use (semantic-add-system-include "/usr/include/c++/4.5.2/") this will work. How do make it work with other codes or headers?

I also tried to use EDE. My project directory is like this:

/project root  
    /lib1  
    /lib2   

and I tried

(ede-cpp-root-project "myproject"
                      :file "/home/user/myproject/Makefile"
                      :include-path '("/lib1"
                                      "/lib2")
                      )

and

(ede-cpp-root-project "myproject"
                      :file "/home/user/myproject/Makefile"
                      :system-include-path '("/home/user")
                      )

However, when I type

#include <myproject/lib1/xx.h>

in my source file, semantic won't parse the correct file and offer the complete candidate.

I just want semantic parse the correct file when I type #include <myproject/lib1/xx.h> . Can I achieve this with semantic or/and EDE?

I have something like the following in my semantic-mode-hook . The variable semantic-dependency-system-include-path is mode-local. Try redefining your-c-include-dirs or your-c++-include-dirs in the following.

(defun your-semantic-hook ()
  ;; these are buffer-local
  (mapc (lambda (dir)
          (semantic-add-system-include dir 'c-mode))
        your-c-include-dirs)
  (mapc (lambda (dir)
          (semantic-add-system-include dir 'c++-mode))
        your-c++-include-dirs))

(add-hook 'semantic-mode-hook 'your-semantic-hook)
