Thanks for your work, i search to compile only receive this error:

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.

More than likely it is a compiler specific issue with the way the method was declared. I can ask Jasem what needs to be changed.

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.

Can you pull and try again?

Compiles now on both my systems, thanks!

Awesome! Now you can test the PHD2 stuff. . .

I just worked on a 3D star profile today.

see what you think.

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).

@knro
Thanks now compile ok.

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!
