il2cpp.exe did not run properly! WebGL

Unity Engine
1

As the title says, I have a problem with il2cpp. I don’t really know how to find what is wrong from the error and the solutions that others had for a similar i2cpp problem didn’t work for me.

Here’s the three errors I get, but I expect that the second and third errors are connected to the first, but I’m posting them as well just to be shure.

I’m trying to build my game for WebGL, but then I get these 3 errors, I used to have 4 but I reinstalled unity and it removed the 4th. Help very much apreciated. :slight_smile:

Error 1:

It looks like the error is:

No mapping for the Unicode character exists in the target multi-byte code page.

I’m not sure what that means, but I’m going to guess that there is some character in the generated .cpp file at C:\DJAM\Temp\StagingArea\Data\il2cppOutput\Assembly-CSharp.cpp which is causing a problem for Emscripten (the C++ compiler for WebGL). Unfortunately, we don’t get any information about what line of the file causes the issue.

Can you try to build this same project for Windows Standalone player with IL2CPP? You will need to install Visual Studio with the C++ build workload to do that. I wonder if that will cause a similar error, but hopefully indicate what part of the file is the problem.

3

Can you submit a bug report and include this project? We’d like to both understand why this happens and improve the error message from Emscripten.

I have same issue did anyone find a fix?

I come across similar (same?) errors on Linux version, when trying to compile WebGL Build for Lego Microgame.

What is curious here is that Unity is trying to run il2cpp.exe when it is running on linux. Is this normal? Building for Linux Standalone with IL2CPP completes without isuues.

There are 3 more errors that accompany this one.

There errors refer to a folder /home/bokken which doesn’t exist and unity doesn’t have the permissions to acces it even if it does.

Yes, this is normal. The il2cpp.exe is a managed executable, not a native one, so it does have a .exe extension.

It looks like the bottom line error is from Emscripten, the C++ compiler for WebGL:

error while loading shared libraries: libtinfo.so.5: cannot open shared object file: No such file or directory

That would explain why the build for Linux Standalone works - it does not use Emscripten.

I’m not sure what this error means, but I’ll ask our WebGL team about it.

This is a path on the Unity build machine - I think it is safe to ignore.

7

Getting all of the Linux dependencies right is a pain. We are working on a sysroot package that will have a self contained environment for building everything Unity related on Linux (il2cpp, emscripten), which will avoid the issues of missing or incompatible dependencies.

I believe you can get past the libtinfo.so.5 error by installing libncurses5, sudo apt install libncurses5.

8

I actually came across this solution in another thread on a similar vein. For Arch and Manjaro sudo pacman -S ncurses (if not installed already) and ncurses5-compat-lib from AUR seems to be the solution, but I’m running into a new set of errors.

I believe this is the error that actually matters. It seems to try and run a OSX version of brotli resulting in an ELF header error?

I found for my issue it was chinese username messing it up, I set up another user with normal username and it works…

It’s never fun chasing dependencies, and truthfully we haven’t spent a lot of low level time with WebGL on Linux to know what all of those indirect dependencies are. I am spending more time with it now, and the sysroot package, when we get that released, will help a lot by having a self contained environment that doesn’t require all this dependency chasing. I believe I fixed the Brotli Python dependency issue previously with a sudo apt install python-pip.
