INDI Library v1.9.9 Released (30 Nov 2022)

Bi-monthly INDI Library released with new drivers and bug fixes.

INDI Crashes on Startup -- 1.8.5 Ubuntu 19.10

Tonight was supposed to be my first night out after a run of cloudy nights. I had upgraded to 1.8.5 as soon as it was available on the stable PPA. When I started INDI, it crashed. The attached drivers were EQMOD, Moonlite, ZWO (2 cameras and 1 EFW). On further testing, both EQMOD with simulators and Moonlite with simulators crashed.

See this bug report: Bug 420490

For more information, the arduino-based moonlite controller was connected for all connections tested. Seeing Ekos Crashing , I disconnected the arduino and successfully connected all the other devices. After they were connected, I could plug in the arduino and proceed as normal.

I will retrigger KStars build and we might need to have a teamviewer session so I can debug in real-time.

I'll give it a go tonight if the build appears in the stable channel. I just updated kstars-bleeding-data, libstarshootg, kstars-bleeding-dbg and kstars-bleeding. Are there any other packages that should update today?

I if crashes, I'll run gdb and post the results. The workaround of unplugging the arduino before starting EKOS and plugging it in after all the other equipment is connected worked for me last night.

Another issue from last night, probably unrelated, I had both ASI cameras change from 16 bit to 8 bit without me being aware of making any changes.

The same happens with your Arduino based SQM. With the SQM connected, KStars crashes. Without it, it runs OK.

Looks like some property is defined without being properly initialized fully yet... where can I get the driver? is it possible to trigger the crash without having arduino?

Plugging in the arduino after everything else works. I can send you the arduino code for my focuser if that's what you want.

Ok please do .. I have arduino around here that I never used in years. What about the driver? is this using indi-duino or just the regular SQM driver?

I think this is the correct focuser firmware; I use an UNO for this implementation. The driver for this is the Moonlite driver.

I think this is the SQM I have (but not connected at the moment). Mine is based on the Leonardo. When I have connected it in the past, I used the SQM driver.

Edit: I forgot to unplug my UNO moonlite focuser. I get essentially the same backtrace if I only have the SQM (Leonardo) plugged in. As with the focus controller, plugging it in after INDI starts works.

I just ran my SQM with only the CCD simulator (which crashed). Here's the gdb backtrace:

Alright, I can't figure this out. I need remote access. I emailed you.

Jasem,

I missed the e-mail (not showing up on any account, including spam folders). I successfully built kstars locally on both the laptop and the desktop and both instances are working well.

Maybe a rebuild of the AMD64 version for Ubuntu 21.04 will be sufficient...
