Tutorial of kdevelop doesn't compile

[Giuseppe Torelli]

Hi Frank,

thank you so much for your reply, however I still have problems:

$ ./test

FAILURE (KCmdLineArgs):
Application has not called KCmdLineArgs::init(...).

What else ? I'm so confusing, I have copied the c++ code directly from 
Kdevelop tutorial page ! 

Do you have a better tutorial on how to build a gui with KDE ??

Thanks,
Giuseppe
