Bug ExecutionEngineException: Attempting to call method 'Unity.Entities.FastEquality+CompareImpl`1

@elliotc-unity I tried 0.51 release at Unity 2021.3.4f1 and build android build but the android failed to run properly and get the following error:

i have this same error.
to reproduce, the project should have com.unity.physics@0.51.0-preview.32 and the project should build for il2cpp

 

I obviously can't speak for everyone, but I think substantially more detailed dev logs on a much more regular basis would go a long way toward assuaging my frustration with these packages and their development. "Seems like soon" is better than radio silence, but we're still experiencing an infuriating cycle where we can neither work with the thing nor do we have any idea what's going on behind the scenes.

Unity is not just software we use, it's the beating heart of our products, and DOTS represents a paradigm shift that's likely to govern the course of our careers. This particular dev hell has been so alienating that I'm no longer sure if I'm a Unity loyalist, or just don't like the competition. Please communicate more.

 

yes, that fixes the problem. Thanks.

 

The setting mentioned doesn't appear under project settings for us, but rather under the classic Build Settings menu.
The workaround appears to work for us as well, thank you!

 

@elliotc-unity Looks like IL2CPP Code Generation not able to serialize into ProjectSettings. Can u make sure it will be serialize into ProjectSettings at next Unity 2020.3.x version? With this current limitation I can't make sure the same project able to get working build at another machine.

 

Ya. It's 21.3 only issue. What I want to say is IL2CPP Code Generation option is actually at Build Settings instead of at ProjectSettings which make not able to save this option into ProjectSettings. I would like to see this option moves to ProjectSettings in future 21.3.x release.

Btw I also curious I need to choose Faster (smaller) builds in order to fix the issue? Is that il2cpp codegen has some bugs?

 

It is probably the Full Generic Sharing feature of IL2CPP. In 2021LTS it's only active with "Faster (smaller) builds". In 2022 it's always on. Got this from a forum post some time ago that I can't find anymore.

 

Where is "project settings -> player -> configuration section -> IL2CPP Code Generation -> Faster (smaller) builds" menu? I cant find it.

 

Its in the old build settings :

 

I can verify that the error is still occurring under 0.51.1-preview.21.

Also, does anyone know how to change disable full generic sharing mode in the scriptable build pipeline (WindowsClassicBuildConfiguration)?

 

I don't have that option:


Also, I'm using the build configuration pipeline because it supports subscenes and I don't see that option there either.


I'm using 0.51.1-preview.21 in unity 2021.3.7f1 and I'm trying to fix the error: ExecutionEngineException: Attempting to call method 'Unity.Entities.FastEquality+CompareImpl'1[[Unity.Physics.PhysicsWorldIndex...]]:CompareFunct' for which no ahead of time (AOT) code was generated".

It gets triggered in an async coroutine when loading prefabs via addressables' LoadAssetsAsync().

 

That was one of the first places I looked, but for some reason I don't have it there:



Is there something I need to do in order to make the option appear?

 

...

 

Ah. I actually had the scripting backend set for il2cpp already, but I had two projects open and I accidentally looked at the settings for the wrong one when I sent my last post . Anyway, thanks for the help - the error is gone!!

 

Just updated to 2021.3.9f1 and I now get the crash with both faster builds, and faster runtime. On Mac, with IL2CPP.

The crash log looks like this for both settings:

Ok thanks, I’ll do some digging and file a report. It kicks in exactly where the initial crash did so I’d thought it might be a repeat.

Update: Looks like compound colliders are throwing the exception (all fine in the editor). Will keep digging.. Faster runtime works nicely!

 

Just tried it sadly it's still doesn't work. I checked the 2021.3.9f1 changelog but it doesn't mention any fix about "faster runtime". I only found this fix.

Spoiler

• IL2CPP: Prevent a memory corruption that could happen when the "Faster (smaller) builds" option is used with generic types that have a generic base class with no fields, and a different base class with at least one generic field. (UUM-3066)

Edit: Now even worst. Both Faster (smaller) builds and Faster runtime options to build game runtime are not working. Launch game it just crash.

 

Same for me. After updating from 8f1 to 9f1, the android build started to crash on start.
Compilation with Faster (smaller) build

 

Not sure whether this will help or not. I will try to provide better one if u need it.

I just rollback to 2021.3.8f1 and it's still working nicely again. I can confirm that in 2021.3.9f1 there are some changes that break Faster (smaller) builds and Faster runtime still not working yet.

 

Have done some digging and it’s definitely the presence of compound colliders that causes my crash, with both faster builds and runtimes. I can run the standalone fine when I remove all of them. Also tried rolling back to 2021.3.8f1, and it seems some (but not all) compound colliders appear to be failing gracefully, so may have been broken a while. Single colliders per body are fine.

 

@Karearea , @elliotc-unity , do not have stack trace right now (OOO), but yes, it definitely had something with Physics and CompoundCollider

 

Hi @elliotc-unity. Did Unity 2021.3.10f1 solves the issue or I need to wait for Unity 2021.3.11f1?

 

Alright. Thanks for reply. Btw is that possible to revert the changes at Unity 2021.3.11f1 first if still can't fix the issue? At least make Faster (smaller) builds setup working again first. Currently I still stuck at Unity 2021.3.8f1 and can't upgrade Unity version due to both Faster (smaller) builds and Faster runtime will crash runtime game build. Currently only Unity 2021.3.8f1 is the latest working version that with only Faster (smaller) builds setup. Faster runtime not working.

 

I see. Btw does Unity 2022.2 Beta get the similar issue for dots 1.0 preview release?
