Hi, I messed a lot with kstars/ekos on ArchLinux and I think I know why these errors happen (I opened the thread you linked).
These errors seem to come from the c++ code itself, archlinux uses by default a lot of flags to compile packages with optimization, if you drop most of them the package will compile without causing Kstars to crash.
Thanks @Mattia. Glad you've got to the bottom of it. One question, does this mean that the official Arch libindi package is broken? Would it make sense for me to raise a bug report against this package?
there unfortunately it's a bit more complicated. I have seen sometimes things working and then breaking after some update to the main stream so possibly builds are not equal to each other.
Now, to my knowledge this issue relates only to the Pegasus driver hence my doubts - possibly this is very hard to catch since very few users use arch for kstars and probably only me and you use the ppba.
I think raising an issue may be a starting point tho, if you do so can you share the link? Thanks!
