c-ide demo: semantic error!

[TheGreatChina]

Hello, I'm following your guide of your "c-ide demo", when I learned the section "CEDET", I've found a confusing error while I use the company-semantic command, it always output:"cannot complete at point" and continuously output:"Wrong type argument: number-or-marker-p". And I'm confusing of that I can't get the same result like your demo when I used company-semantic, or maybe you not used company-semantic in your demo of completing boost::?

Semantic is pretty dated. I suggest you take a look at Emacs cquery and set it up. I will update my guide soon.
