Update. So I had tried compiling LO again. I remembered when I was (cross-)compiling Void Linux for the Pi 4 on my old x86 PC when I still had one, I had issues with my long uptimes and probably with unapplied updates due to no reboots. This time I had 9 days uptime on my Pi. A reboot solved that before.

So a reboot later and trying to recompile... and it fails with the same error.

I had nothing else open, other than my DE and a terminal, so I was using around 150 MB at best, then left LibreOffice to compile and I haven't touched the PC. It should have had around 7.5 GB dedicated to compiling. It's likely that the gallery stuff just doesn't like aarch64.

Any ideas? Should try compiling in a chroot? Or should I try compiling in a Void aarch64 LXD container? I still slightly doubt it's going to make a difference. I don't really want to expend development resources from Void on this, which is why I added low priority in the title. If I knew what to fix, I'd fix it and contribute back.

One thing I researched is that the com:sun:star:uno exception is a Java thing. Maybe some Java dependencies are made for x86 and they fail to run on ARM. That could be one thing. Another one I found is that some people had issues opening up libreoffice because their ~/.config/ folder was for some reason not owned by them. And the last one I found was on OpenOffice that someone was using the UnoRuntime API in a wrong way.

I guess I may as well give LO compilation a try in an LXD clean environment, so I can make sure it's not something from the xbps-src side, related to one of the previous LO compilations.
