I am sure I will make it to the top of the craziest astroberry users!

now, fatal error: RTIMULib.h => very clear, all I need to do is sudo apt-get install RTMULIb-dev

but:

astroberry@astroberry:~/astroberry-diy/build$ sudo apt-get install RTIMULib-dev
Reading package lists... Done

E: Unable to locate package RTIMULib-dev

then I recalled that there is the requirement: * RTIMULib (for Astroberry AltIMU) available here github.com/RPi-Distro/RTIMULib

$ sudo wget github.com/RPi-Distro/RTIMULib

now the file is in the directory, re-running sudo apt-get install RTIMULib did not score any results

what to do?

What about sudo apt-get install librtimulib-dev?

Yes - mission accomplished. Now I can select astroberry focuser!!

Thank you so much for your patience,

Helge

Great to hear that! I have updated INSTALL instructions based on this discussion. Credits go to Helge.

Not sure if I really deserve any credits - really appreciate you are enabling people like myself to use all these great tools you and others were developing!

Now I was wondering about the following: I run KStars/Ekos on the laptop, using the astroberry / Raspberry to run the focuser-driver, connected via wlan. I guess I would start up the driver via ssh command. But on the windows-laptop, in Ekos profile editor, what do I need to chose for the focuser, since in KStars 2.8.2 the astroberry drivers would not be available / could not be selected in the drop-down menus.

While you run remote mode for INDI server you need to type in driver's name in Focuser field. That's all

Dear Radek,

I tried like this (see upload) - but did not work. In the focuser module I could not edit the related field.

I also tried various permutations of rpifocser, but did not succeed. I reckon you meant something else...

Best, Helge

You're almost there. The name of the device is Astroberry Focuser

Yep, now it is starting up.

Thanks and good night!

Dear Radek,

I was reinstalling the astroberry-diy drivers, with this one I have a problem, „cannot be located“

sudo apt-get install librtimulib-dev?

Any idea?

Best, Helge

I don't think there is a binary package available. You have to compile it yourself from sources

Thanks, but about seven month ago, that command was fine. How come it is no longer available?

How does compile from source work? Download, DCMAKE...make...make install? I have to admit, I am still lacking the Linux basics - would be great if you could describe...
