Linux: DllNotFoundException

[royblackstone]

Hey guys! We are back, decided to make this a separate issue since it's more specific/related to the potential issue.

We are working now on getting a version of our game ready for launch using Rive, specifically for Steam Deck.

What we have

• Linux Ubuntu 24.04.4
• AMD GPU
• Unity Linux 6.0 (6000.0.59f2)
• Rive Runtime 0.41
• Vulkan

We are getting issues with loading our game in play mode, in particular it seems it's not finding the DLL runtimes it needs and then subsequently throwing a ton of errors. We've checked that the DLL files do in fact exist in their folders, but it looks like Unity/Rive can't find them for some reason. This is on a clean install of Ubuntu so nothing out of the ordinary for building.

Looks like this might be related to this issue. Could you try the latest canary version (v0.4.2-canary.38) and see if you still have the errors.

In the package manager, you can use:

https://github.com/rive-app/rive-unity.git?path=package#v0.4.2-canary.38

Partial success, we got unity launched but there are other issues.

After building it doesn't render anything, black screen only. All the rive assets are black and unresponsive. The unity layer is fine.
We also started getting crashing issues when selecting the rive assets, so as its populating the profiler it encounters and issue and crashes out, no log here unf, it dies with no indication asto why.

Same issue happens in both a clean unity project running standard settings and our own project that runs fine in windows.

Tested with Vulkan as the only renderer for Linux on Ubuntu 24.04.4, and with Unity 6.0 (6000.0.59f2)

To confirm, is this happening on the machine running Ubuntu?

We also started getting crashing issues when selecting the rive assets, so as its populating the profiler it encounters and issue and crashes out, no log here unf, it dies with no indication asto why.

Is this part in the Unity Editor? Want to make sure I understand what you mean by "selecting the rive assets".

[SW-Fredrik]

Yes, after building successfully as we try to play the standalone app it only displays a black screen - the rive assets are not functioning.

Yes, when the assets manage to get imported, (very unstable process, sometimes crashes). They display the "R" logo etc. At this point when the files are selected, the editor crashes instantly as the profiler should be displayed. So something dies instantly on the rive side when the code executing the profiler view runs.

We did some more testing btw, we tried running this with an empty standard 2d project with newest canary version and a blank rive export, (basically no assets, just some text and a color block, no logic or state machine stuff). It launches in editor, it launches when no rive file is loaded but crashes on select and displays black rive assets while the unity assets load normally.

What Linux version did you build with to display Rive working on the deck?

[damzobridge]

We're currently debugging this. So far, I've been able to run the Unity Editor (on Unity 6) with Rive without the crashes or black screens, so this is a bit strange. I'm using Ubuntu 24.04 with an NVIDIA GPU, using the latest canary:

https://github.com/rive-app/rive-unity.git?path=package#v0.4.2-canary.44

The only obvious difference I can see is that I'm running on an NVIDIA GPU and you're using AMD. To give us more info about your setup, could you copy and paste this environment info from the Unity Editor menu: Tools → Rive → Copy Support Info

What Linux version did you build with to display Rive working on the deck?

Running in Desktop Mode at the moment on Steam Deck, but builds made with the canary versions I've sent also seem to run fine on device as well. I'm testing with this build, so I wonder if that runs for you on your Ubuntu machine and the Steam Deck.

If it doesn't work on your PC (but works on the Steam Deck), then we might be able to narrow it down a bit.
