This seems to be a Qt version issue, on my x64 Ubuntu 17.10 with Qt 5.9.1 it compiles, but on Raspberry Pi Ubuntu 16.04 with Qt 5.5.1 I get this same error.
No jpaana is correct. I just googled it. It does appear to be a QT version issue. Maybe we can change the code slightly and make it work with older qt versions.
Looks nice, unfortunately not straight forward to test on Ubuntu due to the libqt5datavisualization5 module not being packaged even in 17.10 (bugs.launchpad.net/ubuntu/+bug/1727617).
Yeah most likely this would be for those on 18.04+
EDIT: It's not even in 18.04 when I checked today.. so I commented on this bug. Those who have Launchpad account please login and comment as well so it brings more attention to this.
Built kstars from source last night and spent the evening guiding with EKOS/PHD2 and it worked really well - I appreciate the improvements you've made!
That’s good to hear! I have not yet used it in its final version under the real sky due to the full moon and the weather. It has been below freezing for more than 2 weeks and there is significant snowfall. That plus the holidays. I hope to get it out soon, but until then I am working on the 3D star profile. It is almost done!
