I know this is from the last release but since you're talking astrometry problems, it would not work when I tried 3.0.0 last Friday on a Mac. Attached is the log if it helps. I'll probably try 3.1.0 this week.
There is the XPlanet Solar System Simulator which you can see all the moons, but nothing on the Skymap. I will see maybe we can have a Google Summer of Code project for this.. or if we get new developers that want to work on it. Currently, we don't have anyone with time that can work on it.
I took a quick look in your log. There is a space in your file path. "KStars 3.0.0" Astrometry.net chokes on spaces in the filename because it largely works from the command line. You cannot have a space in your path to astrometry if you want to use astrometry.net. I put that into the instructions on the DMG.
But it has not been a problem until now. The same path is used in version 2.9.7 and previous releases without a problem. I think that path was selected by Kstars a long time ago when I first installed it and has been working ever since. So are you saying that going forward the path will have to change?
No, that is a guess as to what might be wrong. In the past, I have observed that a space in the path to astrometry can cause it to fail. It is something to test to see if that fixes the problem. Any time there is an issue, you should test all possible things to find the cause. That is one possibility. Even if it worked before, taking out all spaces Is a thing that should be tested.
3.1.0 for Mac was built completely differently than previous versions of KStars. We developed a build script over the course of a couple of years that was working pretty well up through 2.9.7. But then in January, QT made a change that broke the script to the point it will no longer work. I think some serious issues we had with 3.0.0 were symptoms of the bugs that QT was trying to address, but in the process their change also broke our build system. So I worked very hard in January to develop a new script based entirely in craft (which was a more long term goal anyway) so that we could get building KStars for Mac again.
Ok. Sounds good. Sorry I wasn't able to help test 3.0.0 but I'll do so with 3.1.0. Forgive me for my ignorance but what is QT and "craft"? I've seen you mention them but haven't figured it out.
