Question Yet another IL2CPP build error

Building for Mono works, switching to IL2CPP and I get this:

F:\Programming\Unity\Unity Editor\2021.3.16f1\Editor\Data\il2cpp\build\deploy\il2cpp.exe --convert-to-cpp --data-folder=F:/Programming/Unity/Projects/MyGame/Library/Bee/artifacts/Android/il2cppOutput/data --generatedcppdir=F:/Programming/Unity/Projects/MyGame/Library/Bee/artifacts/Android/il2cppOutput/cpp --enable-analytics --emit-null-checks --enable-array-bounds-check --dotnetprofile=unityaot-linux --profiler-report --profiler-output-file=F:/Programming/Unity/Projects/MyGame/Library/Bee/artifacts/il2cpp_conv_xqeu.traceevents --print-command-line

Does anyone know what's going on?

 

Thank you for your answer. I've been able to solve this problem by... (drumroll) Installing IL2CPP. For some weird reason, it was not installed but still was offered as an option in the Player Settings.

 

Wait no, I spoke to soon!

Ok, so this happened. Earlier this afternoon I went into the Unity Hub, went to "Installs" and saw IL2CPP was *not* installed. So I installed IL2CPP, loaded my project again and low and behold, I was able to build my project using IL2CPP. All during the day I encountered no problems and was able to build with IL2CPP.

Then my PC crashed during a build.

I rebooted my PC and when I loaded my Project, it was corrupted. I got tons of error message it could not load GameObjects, or that it found Game Objects without reference, etc. etc. The loaded scene was completely f****** up.

So I restored the project from yesterday's backup (only the project folder, nothing else). Loaded up the project and everything was fine. But when I tried to build for IL2CPP, I got the same error message as above again. IL2CPP is still installed (according to Unity Hub).

So still no idea what's actually going on.

 

Default Unity build process.

This is so terribly frustrating. I finally had IL2CPP working, now I'm back to square one again...

So to reiterate:

1. I was unable to build my project using IL2CPP because of above mentioned error
2. I check the installed modules and saw that "Linux Build Support (IL2CPP)" was not installed - even though the IL2CPP linker was available (otherwise I could not get the aforementioned linker error)
3. I install "Linux Build Support (IL2CPP)" and building my project using IL2CPP worked (hurray!)
4. My system crashes in the middle of a build. When I restart my PC and load my project, it's corrupt (beyond repair).
5. I restore from last night's backup but now building my project using IL2CPP gives me the same error as before, even though it (IL2CPP) is now marked as "Installed"

So yeah. I'm at a loss for now...

 

Yes I am. I think I found the culprit.Under "Player Settings" -> "Other Settings" -> "Graphic APIs", I had both Vulcan and OpenGLES3 listed.After removing Vulcan, I was able to build without errors.

 

Sorry, I left something out. "Auto Graphics API" was actually enabled. I had to disable it after which I also disabled "Vulcan".

 

This is driving me insane... The error is back. I made a change in the "Managed Stripping Level" setting. Changed it from "Low" to "Minimal". That gave me an error (which apparently was a known problem with a plug-in I'm using) so I change it back to "Low" again and now I'm getting the original error again.

So apparently, the error is not related to one specific thing but just pops up whenever it feels like it.

 

Have you managed to fix this in the end?

 

same problem,2022.2.2,i am Mac m1 user

 

For me, it definitely had something to do with the Graphics API settting (in the Player settings). I enabled "Auto Graphics API", immediately disabled it (and I think I also removed "Vulkan" at that time) and the error went away and never came back...

 

could not find that option on 2022.2.2

 

i downgrade project from 2022.2.2 to 2021.1.23 my problem resolved!

I took build for iOS!!!

 

Same problem here.
We had to pass to 2022 for the navmesh features, but unable to build on iOS since then...

Deleting the Library folder in my project and reopening my unity project and building again fixed this issue for me. I was seeing the error


Error: il2cpp.InvalidCommandLineArgumentsException: One or more assemblies must be specified using either --directory or --assembly

But after doing this it went away

 

Deleting Library folder also fixed the issue for me

 

Don't remove all Library folder.
Just remove Il2cppBuildCache in that one. Your next build will be ok.
