This is already known and fixed upstream, but not released yet. https://github.com/indilib/indi-3rdparty/pull/1155

or just try now :) I added !lto to the options in PKGBUILD directly

I think the missing deps may be the problem, that's why I want to experimenting with docker/qemu. I build on both x64/aarch64 with no issues at the moment.

Sorry I somehow missed your first response notification. Maybe there is something with the architecture ? In my case I'm on x64, not arm as the RPI is.

Also sometimes I think dependencies are provided by the local installation without being aware of it ?

For instance the phd2 PKGBUILD on the AUR is missing a ton of dependencies on a clean, almost empty install. I doubt that would go unnoticed if it weren't for the majority of users building it on a machine with many dependencies already installed.

I build my packages on a dedicated builder VM.

ok, this is a lil weird. I package them also on a raspberry pi with the same PKGBUILD and never got any issue. Will try to make a docker container starting from scratch and check it out. Thanks!

I have the same problem as blemasle... Its not building because of linking errors

You're missing libftdi in the dependency list. Also, I cannot build the package locally because of ld errors

Have you ever encountered this ?

this together with indi-3rdparty-drivers bring in all libs and drivers except for CAUX, DUINO, AHP_XC, SX and ATIK

Additionally, it works with QHY cameras adjusting the path where the drivers are stored and the dev rules responsible to load the firmware onto the camera
