Completed enviorment set up….
It is so slowly. I almost can’t bear endless problems in compiling KDE4 and kdepim. It’s a nightmare, and the reason I didn’t find yet. 
I wasted two weeks on setting up enviorment, partly because of my intern takes me much time. It also because of my inexperience. In fact, in these day, I was so dispirited…
I will speed up on development.
That’s all by now.
