Attempting to setup C++ project using CEDET/EDE

Question

I have a couple C++ projects that I am working on. I have been using semantic for the sake of autocompletion. However, I want to make better use of the tools out there.

I have the following directory structure

• project/
  • Makefile
  • src/
    • my .cpp and .h files
    • couple_other_directories/
  • test/
    • my test files

I currently have the following in my .emacs

(load-file "~/.emacs.d/vendor/cedet-bzr/cedet-devel-load.el")

(add-to-list 'semantic-default-submodes 'global-semanticdb-minor-mode)
(add-to-list 'semantic-default-submodes 'global-semantic-idle-local-symbol-highlight-mode)
(add-to-list 'semantic-default-submodes 'global-semantic-idle-scheduler-mode)
(add-to-list 'semantic-default-submodes 'global-semantic-idle-completions-mode)
(add-to-list 'semantic-default-submodes 'global-semantic-idle-summary-mode)
(add-to-list 'semantic-default-submodes 'global-semantic-show-parser-state-mode)
(add-to-list 'semantic-default-submodes 'global-semantic-highlight-edits-mode)
(semantic-mode 1)
(require 'semantic/ia)

(require 'semantic/bovine/clang)

;; PROJECTS

(global-ede-mode t)

(ede-cpp-root-project "MyProject"
                      :name "My Project"
                      :file "/path/to/project/Makefile"
                      :include-path '("/path/to/first/includes"
                                      "/path/to/second/include")
                      :system-include-path '()
                      :spp-table '())

Whenever I have the project open, and C-c . g I get an error in the mini-buffer Method project-rescan called on nil Which prevents me from scanning all of my source files for the sake of auto-completion.

What am I doing wrong here?

I've been attempting to follow Alex Ott's A Gentle Introduction to CEDET but it does not seem to mention anything about this error.

I'm also using CEDET from bazaar.

This is what my M-x cedet-version looks like.

CEDET Version:  2.0

The keybinding C-c . g which is bound to ede-rescan-toplevel is for scanning project definition data and not for parsing your source files. Since the ede-cpp-root-project doesn't have definition data in the project, it never implemented that function.

If you visit a source file, that source file will get parsed as needed. It will also find your includes and parse as needed. Also, if you just wait around a little bit, it will reparse all the files near the one you are editing in idle time, so that by the time you need it, the data should be around.
