The libev-dev part worked but update_indi_core still looks a bit weird:

stellarmate@stellarmate:~ $ sudo apt-get -y install libev-dev

libev-dev is already the newest version (1:4.25-1).

Yes sorry, I'll improve the script to be more reliable on SM OS v1.7.2 release. At any rate, for now do this first:

OK, the build process worked with one error message that the indi directory existed and wasn't empty. the update_indi_core command appears to have worked fine.

Sadly the update has caused my Canon driver to crash when starting Ekos. I think there was a comment about this already. When I get a moment I'll go back and reread the thread but for now the system appears to be unusable.

Also, both of the red error message about Zero Microsteps per worm revolution is now a warning message in an orange/yellow color.

It says 'Possible corrupted data'.

Am I to understand that you do not see this on your AZ-GTI?

For 3rd party drivers (Canon..etc) run this:
Yes, with my AZ-GTi, I get worm gear count.

Different firmware in our AZ-GTI's? I've updated 6-12 months ago for the equatorial mode but I think this error, now a warning, was there before. Just not totally sure.

Anyway, I need to solve the canon driver crash first.

OK, so I see I need the indi-3rdparty code.

I need instructions to download and build it on Stellarmate. I'm not a programmer.

Just run this command as I indicated above:

I tried that but it failed. Error message below. That's why I thought I had to go to Github.

That doesn't look right. Do this:

Agreed: It doesn't look right but that's what it does. I've completely removed the Projects directory, rebooted and tried a couple of times. It fails.

Question: The github build instructions had me install a bunch of libraries, some of which I could find and some of which I could not. Might those be causing problems?
