Problem generating a simple class diagram

[Odin]

Good Morning,

I am trying to generate a simple class diagram from a c++ project
using together. I remember last time I used it (before eclipse
version) it was very easy. But now I am lost.

I have tried all, but apparently when I see the class diagrams
Together generates by default, my folder appears empty no matter what
include/exclude filters I apply.

I would appreciate any hint on this.

Thanks,

Diego.
