IL2CPP Android Build LLVM Error: out of memory

Unity Engine
, ,
1

Hello, I am having an issue with the build. If anyone has any knowledge with this, I would be grateful.

I am building my game for android using IL2CPP and am seeing a crash in clang.exe with out of memory. The clang.exe uses around 12GB of RAM, memory usage goes up to around 96% then the build fails. I am using Unity version 2019.3.0f3. I am also using tiles heavily in the game and Scriptable Objects as well. I know this is little to go on, but I’m not sure what else to say that could help.

I have already reported a bug. I am writting here to see if there is however a quick fix for this.

Thanks in advance.

Here is the error I am receiving:

any solution?

3

Just in case, you do have Virtual Memory enabled on your machine, right?

4

I set 10gigs - 30gigs but build still failing (I have 12bg ram)

5

I set 130 gigs - and after 6 hours of building unity freezes - my explorer looks like this (sorry screen contains in czech language) but oyu can claerly see, taht uniy eats over 124 gigs of memory… I assume, that it is not normal beahve

Can you paste the case number here please? It might be that some script in your project creates huge cpp files.

The cpp files are generated here - C:/Users/daian/Documents/Bitbucket/DungeonCrawlTycoon/Temp/StagingArea/Il2Cpp/il2cppOutput check if there are any huge ones, that might hint you what the problem is.

7

what do you mean by “case number”?

8

You said "I have already reported a bug. ", you should have received an email with bug link, it contains a number of your Case

9

Ohhh I see. But I am not creator of this topic… I only facing exactly same error…

10

Ok I tryed another build - Iam attaching screenshot of cache direcotry (it does not look like that there are some huge files) - total cache directory size is 511 MB.
Iam also including my build log

I am sorry, I should have read more carefully.

Still, I think you should create a bug report with repro attached, since otherwise it’s only guesses on what’s happening.

You pasted a screenshot with object files, what about cpp files, are there any huge ones?

P.S as you saw, the bug happens in Android’s native compiler which is a part of Android NDK, so we can only workaround the problem here, the fix (if there’s really a bug) must come from google.

12

no there are non “.so” files generated - only files “.o”

13

what about .cpp files?

14

none… only “.o” files nothing more

15

There should be cpp files in E:/Dev/AoLArena/Unity/Temp/StagingArea/Il2Cpp/il2cppOutput right after the build, unless you’re closing Unity, then the whole folder is deleted.

16

I found this directory, but it did not coitains any big files Clip2Net — screen capture tool for Windows, Android, iPad, Mac, Linux 450MB in total

17

That’s a lot, by might be normal for your project, in the build report above , the compiler crashed when compiling

C:\Users\daian\Documents\Bitbucket\DungeonCrawlTycoon\Temp\StagingArea\Il2Cpp\il2cppOutput\Assembly-CSharp.cpp

Preprocessed version was placed here - C:\Users\daian\AppData\Local\Temp\Assembly-CSharp-884182.cpp, try opening it, and see if there’s a huge method inside, it might be the reason for compiler to crash.

If that’s the case, you might need to split the method into smaller ones

YES! problem solved - there was arrays with hundres of elements and il2cpp was unable to compile it… I moved data to text file, and Iam loading it from it and build passed… Thanks for oyur help!

I had the same issue after switching to IL2CPP and it was driving me crazy. Thank you for finding the solution!
The same issue with some large arrays causing the compiler to eat up all my memory and eventually crash.

Hello, when try build Android build IL2CPP (netstandart 2.0) for ARM64 architectur an error occurse. (Unity 2021.2.0b4)
Assembly for mono and windows works properly.
There are no huge arrays or large static objects in the code.
I tried different configuration options with IL2CPP,
I ask for help with debugging, where should I pay attention?
