Just updated my Arch packages and seen indi was upgraded to 1.9.9 from 1.9.8 where I had a working camera, but no working Mount (OpenAstroTracker).
Now that I am on 1.9.9, it seems the Mount will start, but the camera fails with that error in the title.
With high probability, I can say that indi_gphoto_ccd was recompiled for an older version of the library. Using a new library requires recompiling programs that use it.
While I wait for 3rd party to get updated, can indi be used to connect to gphoto2 itself without indi_gphoto?
I tried to compile the 3rd party stuff myself, but seem to be having issues. Not sure if its related to my compiling or not, so I figured might be nice to try gphoto since it seems to have full support.
