Sorry, I'm still very busy, so qastrocam-g2 isn't maintained any more. Canonical introduced many changes in the last Ubuntu release, and qastrocam-g2 is getting harder and harder to run on this distribution. If you want to use qastrocam-g2 on the last Ubuntu LTS (12.04), you have to install the libqwt3dplot library. This library can't be found in the default repositories. It can be found in this page : link
Once this library installed, the last qastrocam-g2 4.8 binaries should work. Sadly, the Toucam and the QHY5 cams won't work. I will have to rewrite some stuff.
Best regards !
