IL2CPP Build Fail

Unity Engine

I am not sure if this is Unity problem or not, but I can highly suspect it so I will write it down.

When I build using il2cpp (windows pc, not UWP) I get the following error :

Failed running C:\Program Files\Unity\Hub\Editor\2020.2.0b5\Editor\Data\il2cpp/build/BeeSettings/offline/bee.exe --useprebuiltbuildprogram

stdout:

Now, the same empty project does build fine using Mono.

The same empty project does build with Il2cpp using Unity 2019.4 version.

All of the tests are run on the same PC.

I donā€™t even know if it is worth while to send repo bug report, because, well, the project is simply empty. I have created a brand new project and just attempted to build.

Since Unity 2019.4 builds fine with il2cpp, I am more leaning towards that it could not be the setting on my pc.

Using Visual Studio 2019. 16.7.5
Unity 2020.2 b5

Any ideas?

My guess is that the non-ASCII characters in the path to the project are causing a problem somewhere. We do a good bit of testing with project paths like this, but something might have been missed. Can you submit a bug report for this issue?

I tried to reproduce your issue by using what looks like the same project directory and directory layout, and I was able to get an error, but not the exact same one you hit.

Iā€™m working on a fix for the error I was able to reproduce, and hopefully it will fix your issue as well.

To check if perhaps thereā€™s something else unique to your machine or setup, could you do a test of creating and building an empty project into a directory that only has ASCII characters in the path? If that works, then Iā€™m pretty sure my fix will alleviate your problem. But if it still doesnā€™t work when using a project path with only ASCII characters, weā€™ll know something else is the issue and then we can narrow it down more.

Thanks will try that and report tonight.

I have done some more experiments and here is my finding :

Empty project :

  1. Ascii only folder path names : Works!
  2. The same project with Unicode path name : Fails!

My actual project :
Project path name doesnā€™t have any unicode characters, but fails with the following error :

il2cpp.exe didnā€™t catch exception: Unity.IL2CPP.Building.BuilderFailedException: Rewired_Core26.cpp

C:\Subterrain\subterrain2RPG\UnityProject\Library\Il2cppBuildCache\Windows\x64\il2cppOutput\Rewired_Core26.cpp(21796) : fatal error C1001:

It looks like it failed on Rewired_Core26, which is sad, because it seems like Microsoft STILL didnā€™t fix the compiler bug even after so many months and the last update to the Visual Studioā€¦

Right on, thanks for checking into that! Iā€™ll put in a fix for the Unicode character pretty soon here.

Thank you! Would you be kind to press Microsoft to fix rewired compile bug please? It has been months after months since the issue has arised but the fix is not comingā€¦

Hi @castor76 Were you able to submit a bug report for the ASCII char issue?

10

I did not. But apparently the ascii issue is fixed?

I also got a similar error. Can you have a solution for my project ?

Please copy the full text of the bottom pane from that error message, and paste it here.

I had the same issue using Unity 2020.2.6f1
Removing non - ASCII letters from the project path solved the problem.

Hello. Another similar error with IL2CPP when I build for android (or PC too). I have installed Unity 2020 LTS (3.2f1) and the Android SDK and NDK from Unity Hub (just mention that Visual Studio was not installed due to a problem with NET framework 4.7.2 and Windows 7).

I am doing the tests with an empty project. Any idea where I can start looking? Many thanks.

This here in Spanish is weird or is it normal? ā€¦ā€œerror: Mļæ½todo no encontradoā€ā€¦
Windows 7 is in Spanish, but everything else is in English.

This is the console log:

This might happen because there are spaces in the path to the Unity project:

C:\Users\USER\Unity Games\Snake Game

Can you try to remove those spaces? We have a bug around this issue, and a fix is on the way to a 2020.3 patch release, but you might be able to work around the issue sooner.
