Error loading needed lib UnityPlayer.so

[tmahlstrom]

I'm trying to run my own Unity game on my Pi 4. It looks like it's not able to find UnityPlayer.so.

Is that something I need to install separately? Apologies as I'm new to many of these things.

is this lib UnitPlayer.so present?

[tmahlstrom]

I can't find it. Tried ldconfig -p | grep UnityPlayer.so.

Again, total linux amateur here. Is there a simple way to install it? sudo apt install doesn't work. Should I have to do this, or is it fishy that I would have to do this at all?

Very much appreciate the help.

Some more details:
I installed box64 following this guide https://pimylifeup.com/raspberry-pi-x64/, and did end up installing version 0.2.4 for my pi 4. The latest version wasn't installing and one comment said that worked best for pi4. Could be that I only have 2GB.

I tried building the Unity game with mono and IL2CPP. Both got same error.

Edit: thinking more, the problem is likely that I'm using the older version of box64, yeah? If so, should I expect 2G to be enough to install this? Recommendation on swap file vs swap partition, if needed?

Welp, UnityPlayer.so is created by Unity when it builds Linux games. I just wasn't carrying that over to the Pi.

Thanks.
