Could you try v0.4.2-canary.18 and let us know if you still have the issue on that version.

Got Unity editor crash on importing. Unfortunately nothing specific in logs:

Can you provide a script, preferably a Dockerfile, to avoid dependency hell to build rive-unity so I could debug it?

[damzobridge]

Thanks for getting back to us. Usually, if this is crashing on Linux, it's either because it is being run in an unsupported environment or because the project isn't using Vulkan as the graphics backend. Right now, we support running the plugin on Ubuntu 24.04, with plans to support 22 as well.

Unfortunately, we currently only provide the built native libs in this repo, but we're working on eventually making the code for building them available here as well.

Hey @damzobridge I came here to say that I was also missing the Lua runtime symbol, and upgrading to the canary build solved my issue! Thanks for the help! Are you statically linking Lua or shipping Lua as part of that canary?

[damzobridge]

Thanks for letting us know @SubtleCo . For Linux, it is statically linked into the rive-unity package library.
