In
the stellarmate support page about Ekos
, there is documentation about the FITS Viewer.
There, there is a section about the 3D Star Profile & Data Visualization Tool where it says:I've been looking around the EKOS modules for an hour trying to find this tool. Same In FITS Viewer: I am unable to find where to activate it.
This option was vanished since some kstars/ekos releases (maybe when 3.x.x began)...it was found in the floating bar (focus, align and guide module of ekos)
Curious, car this option is still there when i'm using kstars on my Windows 10 laptop (connect remotely to my RPi4).
But i can't find it nor in my RPi4 with Stellarmate, nor my other Rpi4 with ubuntu 20.04 LTS!
3D star profile feature requires optional libqt5datavisualization5-dev package to compile which was not available in Ubuntu versions before 20.04. Unfortunately there is no way to declare an optional build dependency so it's not listed as build dependency for PPA packages and thus doesn't get enabled in the build. It could be enabled for 20.04+ but would require separate build control files. If you have it installed and rebuild KStars yourself, it does get enabled. Windows and Mac versions use newer versions of Qt so they have had this for a while.
Thanks @jpaana for the explanation. Unfortunately for me, I am completely lost with the complexities of build dependencies, compilation...
What about Raspberry Pi OS which is where Stellarmate is built from ?
Was this qt5 library also lacking ?
I found
here
that it can be installed.
I don't know how Jasem builds the Stellarmate packages, but if he's using the same packaging control file that is in the repository, it doesn't have that dependency either so would require similar recompile than Ubuntu.
This was exactly what I was missing. (First had to install stellarsolver to be able to compile kstars, build page instructions seem outdated; but once compiled it works!)
