Help running app on Linux running under Parallels

Unity Engine
,
1

I am not a Linux user but am trying to release a Linux build of my app. To test it I installed Mint 20.2 in a Parallels VM on macOS. I downloaded and unzipped my app into my Linux desktop. Here is what is in the folder.

parallels@parallels-Parallels-Virtual-Platform:~/Desktop/OurGalaxy_Linux$ ls -l
total 73072
-rw-r–r-- 1 parallels parallels 16064 May 23 15:05 LinuxPlayer_s.debug
drwxr-xr-x 5 parallels parallels 4096 Aug 25 16:58 OurGalaxy_Linux_Data
-rwxr-xr-x 1 parallels parallels 14744 May 23 15:05 OurGalaxy_Linux.x86_64
-rw-r–r-- 1 parallels parallels 41300976 May 23 15:05 UnityPlayer_s.debug
-rw-r–r-- 1 parallels parallels 33482064 May 23 15:05 UnityPlayer.so

I manually made the OurGalaxy_Linux.x86_64 executable.

When I run it, a window briefly flashes on screen and then the app exits. Running from a terminal window doesn’t provide any useful info.

parallels@parallels-Parallels-Virtual-Platform:~/Desktop/OurGalaxy_Linux$ ./OurGalaxy_Linux.x86_64
Set current directory to /home/parallels/Desktop/OurGalaxy_Linux
Found path: /home/parallels/Desktop/OurGalaxy_Linux/OurGalaxy_Linux.x86_64
parallels@parallels-Parallels-Virtual-Platform:~/Desktop/OurGalaxy_Linux$

I did run the Logs app but I don’t see anything in the logs that looks relevant. Can someone give me some pointers on how to figure out what the problem is?

What’s inside the player log? Unity - Manual: Log files

Thanks for responding. Here is what I see:

So it seems it can’t create a graphics context. Do I need to install OpenGL?

4

I tried to install OpenGL following the commands in Part 1 here How to Install Mesa (OpenGL) on Linux Mint: Step-by-Step

That by itself didn’t help. I get the same message in the log. Is there another step?

5

I’m not sure, but it seems that your VM doesn’t support neither OpenGL or Vulkan so Unity fails to run. You’d usually need to install a graphics driver to fix it.

6

I use Parallels to run Windows on macOS and it runs fine there. Is it using DirectX there rather than OpenGL?

ETA: I did just find this: KB Parallels: OpenGL support in Linux and macOS virtual machines

7

Yeah on Windows it uses DirectX.

8

OK, I did a few updates that I hoped would help. This time it still doesn’t find OpenGL, but it looks like it attempts to use Vulkan. It still fails, but in a different way. Can you tell from the log what is happening?

Looks like it crashes within the Vulkan driver now.

10

Yes, I can see that. The question is whether there is anything I can do about it? Is there anything special I need to do to enable Vulkan support when building the Linux app?

11

Try looking at the output of “glxinfo” and “vulkaninfo” (they come from “mesa-utils” and “vulkan-utils” packages). Some of my coworkers said they had better luck with 3d graphics on Linux with VMWare Fusion as opposed to Parallels.

12

Was investigating this issue recently, looks like code in Unity engine filters out devices that have deviceType==4 (i.e CPU and not Discrete/Integrated GPU), then it calls vkGetPhysicalDeviceQueueFamilyProperties vulkan API with a null instead of device id, which may be a bug, causing this segmentation fault crash.

I patched and re-build the llvmpipe (in mesa source code) so it reports different deviceType now and it works fine, here is the corresponding line https://github.com/mesa3d/mesa/blob/498a8e77dd9a437f0af48c6c4921e87057cf4d61/src/gallium/frontends/lavapipe/lvp_device.c#L999

it feels your GPU driver is not properly installed so vulkan does not detect your gpu. You can check with vulkaninfo and see if the GPU is detected, and you can run inxi -G to see what is the default renderer. If it is llvmpipe, your GPU driver is not installed correctly. glxinfo | grep vendor should give you the same thing.

if that is the case, gpu drivers need fix first until vulkaninfo shows the correct renderer.

Has anyone found a solution to this? With Unity being a cross-platform development app, I would think supporting VMs to actually test your cross-platform builds would be a high priority. High enough, for example, that they might supply VM configurations for the two major VM platforms (Parallels and VMWare) that just work out of the box.

Barring that, step-by-step directions on how one could configure a virtual Linux box for testing would be really helpful. Anyone?
