Cannot run linux .x86_64 unity app on raspberry pi CM4

[BasedSnake]

Greetings all, Me and my team are trying to get a unity application built for linux 64 runnning on a raspberry pi CM4, upon running the following command, we get the following prints and the screen flashes black and the application exits. We tried installing openGL, have also tried building for windows and running through wine, this gives us an error that graphics cannot be initialized because of DirectX11. Thank you in advance.

Unity3D redirect logs inside /.config/unity3d/COMPANY_NAME/PRODUCT_NAME/Player.log so check there for details.

I might be a need for BOX64_DYNAREC_STRONGMEM=1? Difficult to say without logs.

[BasedSnake]

unfortunately we cannot find the aforementioned directory, any potential other locations or place we didn't look? BOX64_DYNAREC_STRONGMEM=1 did not work either.

[ptitSeb]

The directory I mentionned is a generic template. You need to replace COMPANY_NAME by the actual company name settuped in Unity. Same for PRODUCT_NAME.

[BasedSnake]

We were looking in the wrong directory for it, here it is:

Using emulated /home/gravitron/Desktop/test/gravitron_Data/MonoBleedingEdge/x86_64/libmonobdwgc-2.0.so MonoBleedingEdge detected, disable Dynarec BigBlock and enable Dynarec StrongMem Using native(wrapped) libz.so.1 Mono path[0] = '/home/gravitron/Desktop/test/gravitron_Data/Managed' Mono config path = '/home/gravitron/Desktop/test/gravitron_Data/MonoBleedingEdge/etc' Display 0 '0': 1600x1200 (primary device).

Unable to load player prefs Desktop is 1600 x 1200 @ 0 Hz Using native(wrapped) libGL.so.1 Unable to find a supported OpenGL core profile Failed to create valid graphics context: please ensure you meet the minimum requirements E.g. OpenGL core profile 3.2 or later for OpenGL Core renderer Using native(wrapped) libvulkan.so.1 [Vulkan init] extensions: count=3 [Vulkan init] extensions: name=VK_EXT_debug_report [enabled=0, external=0] [Vulkan init] extensions: name=VK_EXT_debug_utils [enabled=0, external=0] [Vulkan init] extensions: name=VK_KHR_portability_enumeration [enabled=0, external=0]

it seems it has to do with OpenGL, we put the MESA_GL_VERSION_OVERRIDE=3.2 and PAN_MESA_DEBUG=gl3 as arguments. What else could cause this?

Thanks in advance.

[ptitSeb]

Yes, missing opengl stuff. On a PI4, only MESA_GL_VERSION_OVERRIDE=3.2 is usefull. the PAN_MESA_DEBUG one is for Panfrost mesa (so for other boards, like RK3399 or RK3588 based).

I don't think you have opengl activated. Try to use glxinfo -B to see what kind of OpenGL you have. Can't really help you here.

[BasedSnake]

glxinfo -B returns command not found, I assume that means OpenGL is missing?

[ptitSeb]

this comes with sudo apt install mesa-utils iirc. But yeah, looks like you are missing stuffs.

Hello!Did you manage to solve it? I am having the same issue. I built a Linux app through Unity and tried to run it using Box64 in Pi 5. The terminal message I received is exactly the same as in the first comment of this thread. When I checked the OpenGl version typing glxinfo -B I got this warning: v3d support for hw 71 is neither a complete nor a conformant OpenGL implementation. Testing use only Could this be relative? Thank you in advance for any update

[BasedSnake]

Perhaps the warning is relative, we ended up switching to latest ubuntu on pi imager. The only issue we have currently relates to running the application in fullscreen. We get a black screen unless we add -screen-fullscreen 0 as a launch option. I believe our current issue is related to wayland or perhaps the fact that our power supply is 1amp which might be too weak for the GPU to function correctly, but it's "working" for the time being.

[FoteiniS-Verkehrshaus]

Thank you for your reply! I managed to run it with Box64 with terminal command MESA_GL_VERSION_OVERRIDE=3.2 ./YourUnityApp.x86_64 . Fullscreen, the graphics' quality is good but the performance not really. I have already started switching to Ubuntu and I ll test it the following days.

[LukeShortCloud]

Glad to hear you got it working! Feel free to open up a separate GitHub Issue regarding the performance issues if you are still encountering those. Closing as complete.
