Unity 2019.3 Linux IL2CPP player can only be built with linux ERROR

.

 

@Tautvydas-Zilys How do we build for Linux with IL2CPP with 2019.3? It says you need a sysroot package. Where do I find this package? Which package is it? I searched for it and found chromium packages.

I'm using Unity 2019.3 installed on Windows, trying to build for Linux using IL2CPP.

 

I also have issues building Linux with IL2CPP. I have installed various 2019.3.x Editors and also used Cloud Build to use various Editor versions. No IL2CPP build succeeded.

I have tried to build using IL2CPP on a Linux machine and installed different Unity Editor with IL2CPP support. But there it fails with `Exception: /home/user/Unity/Unity2019.3.0f5/Editor/Data/il2cpp/build/deploy/net471/il2cpp.exe did not run properly!` which is obviously a problem, because it tries to execute a Windows executable. Where is the Linux `il2cpp` binary?

 

@andrews_unity as mentioned in the post, the error I get when building on a Linux machine is:

Code (CSharp):

1. Exception: /home/user/Unity/Unity2019.3.0f5/Editor/Data/il2cpp/build/deploy/net471/il2cpp.exe did not run properly!

This is obviously a problem, because it tries to execute a Windows executable even though it's a Linux machine. You can see in the path that it is a Linux path and not a Windows path.
Where is the Linux `il2cpp` binary? Can I somehow configure which il2cpp binary to use?

 

I'm getting error:

I'm not cross-compiling, it's Linux on Linux (Ubuntu 18.04 x64), Unity 2019.3.6f1. Mono build works fine, Burst works.

 

That's exactly the issue I'm also getting. I can add, that I tried it with different versions:

• 2020.1.0b2
• 2019.3.5f1
• 2019.3.0f6
• 2019.3.0f5

 

Thanks @davidbuckley_unity, I just tried this.
I see the parameter is added to the il2cpp call. However it still tries to execute the `il2cpp.exe`, which is a PE32 executable and cannot be run on Linux.

I have used

find . -name il2cpp

to look for the binary, and I only found one in the 2020.1.0b2 version. It looks like none of my installed 2019.3.x versions shipped with a il2cpp ELF binary.

Compiling on 2020.1.0b2 caused a different error, but it used the correct Linux ELF binary! I noticed that the binary was not executable, so fixed it with

chmod +x ./il2cpp

.

Then I got another error that Unity can't find clang. So did

apt-get install -y clang

.

And that finally worked. so to summarise:

• Unity 2020.1.0b2 seems to ship with a il2cpp ELF binary
  
• use

  find . -name il2cpp

  to find the binary and make it executable

  chmod +x /path/to/il2cpp

• make sure clang is installed

  sudo apt update && sudo apt-get install -y clang

• Fix the sysroot with the script by @davidbuckley_unity . Create the file in the Editor folder: Assets/Editor/MySysroot.cs https://forum.unity.com/threads/uni...e-built-with-linux-error.822210/#post-5631169

 

I've been able to work around the issue in 2019.3.0f6.
I have installed clang as @LiveOverflow recommended, but I was still getting error:

With the help of https://forum.unity.com/threads/pro...-clang-installation-path.849760/#post-5623207 I have updated MySysroot as:

Code (CSharp):

1. using System;
2. using System.Collections.Generic;
3. using UnityEditor.LinuxStandalone;
4. namespace UnityEditor.LinuxStandalone
5. {
6.     public class MySysroot: Sysroot
7.     {
8.         public override string Name           => "MySysroot";
9.         public override string HostPlatform   => "linux";
10.         public override string HostArch       => "x86_64";
11.         public override string TargetPlatform => "linux";
12.         public override string TargetArch     => "x86_64";
13.         public override bool Initialize() { return true; }
14.         public override IEnumerable<string> GetIl2CppArguments()
15.         {
16.             yield return "--sysroot-path=/";
17.             yield return "--tool-chain-path=/usr/lib/llvm-6.0";
18.         }
19.     }
20. }
21.  

And now the Linux IL2CPP build works.

 

Interesting. Why is there a ELF il2cpp binary shipped in Unity 2020.1? I guess it changed from 2019 to 2020. It used to be run via mono, now it's a ELF binary?

 

Hi!

I'm having a similar issue trying to build for webgl. I have tried using the script provideded by @davidbuckley_unity
, however that script throws errors on 2019.4.3f.

I've tried to get clang like mentioned by @LiveOverflow and change the chmod, however that didn't seem to help. As a dirty workaround I used a cloud build but this is obviously not ideal.

Here is the output that I get after trying to do a WebGL Build:

Is there any way to build for Linux from windows on 2019 LTS yet? It is possible on 2018 LTS, and only about two weeks ago decided to update the project to 2019 and now that I wanted to build I'm running into this issue.
If IL2CPP is the issue, why cant we just build to whatever it was previously?

 

Thanks! Much appreciated

 

@Tautvydas-Zilys Does your suggestion to switch to Mono for a Linux build on a Windows machine imply that it's not possible?
If it is, what steps would be required?

 

Any update on this? It's odd that some platform based on Linux compile IL2CPP just fine, but not Linux itself.

 

Sadly doesn't work. I would direct you to; https://forum.unity.com/threads/cannot-have-ps4-and-linux-package-installed-at-the-same-time.994822/

And since someone thought it was a good idea to remove non-dev mono build from Linux, I'm rather stuck.

 

Here's the Linux variants installed with 2019.4.11:

• headless dev il2cpp
• headless non-dev il2cpp
• withgfx dev il2cpp
• withgfx non-dev il2cpp
• withgfx dev mono

There's no "non-dev mono" build. Trying to build master mono just failed saying the variant is missing.

EDIT: Never mind, just found out Linux was split into Linux (IL2CPP) and Linux (Mono) as install modules.

 

I am on Unity 2019.4.9f1.
If I change the build platform to Linux, I still get shown a notification in the build window...

Building Linux IL2CPP player requires a sysroot toolchain package to be installed.

EDIT : I found this post with information on Linux IL2CPP support, and how to install the 'hidden' preview package to enable building for Linux IL2CPP when using Unity Editor on Windows.
