You're right, I did not give a lot of informations. Sorry.
I'm working on a laptop PC, Ubuntu 16.04.
The test I did is purely local : Kstars running on my PC, and the Indi server as well.
It worked before (few weeks ago, at least), with the same PC. I'm not sure if the problem appeared when I did upgrade to Indi/Kstars new versions, or before.
64bit on 16.04 is problematic due to an older glibc and I think Atik built the SDK with a more recent glibc. I will see if I can get them to send me something that works in 16.04 as well, or you can upgrade to 18.04
Ok, good to know. Thanks.
I will not upgrade my PC shortly, but the Indi server can be elswhere (on an RasPi, indeed). Then, I may work around the problem (I guess the problem with 16.04 is the Indi server, not Kstars - right ?).
I'll tell you if I still have problem. And if you want me to check a change on your side, jut ask.
