Burst - Unexpected exception Burst.Compiler.IL.Aot.AotLinkerException

Unity Engine

I’m getting some errors upon loading the Editor on Windows. They do not appear on Mac, where I work primarily.

I’m also unable to build on Windows because of them. Again, everything is fine on Mac with the same code and Unity version.

Here’s my editor log, which includes the error on load and a failed build.

Luckily, since cross compilation was added to Burst, I can still make a Mono Windows build from Mac, but I’d prefer IL2CPP ideally. And I figure I can’t be the only one with this problem, right?

So today I tried a fresh Unity 2019.3.15 install on MacOS 10.15. Using Burst 1.3.0. I have Xcode command line installed as required.

When I open my existing project. I got very similar errors related to Burst. The first one read:


While compiling job: System.Int32 Unity.Burst.Intrinsics.X86::smile:oGetCSRTrampoline()
at <empty>:line 0
(Filename: Line: 0)

I’ve attached my full editor log.

What’s going on here?

Hi, this looks like a possible permissions issue, could you repeat the error and then perform an ls -lha from a terminal on the folder shown in the error, e.g. for the above :

ls -lha /Users/brettjohnson/Documents/Stealth%20Adventure/Temp/Burst/burst-aotjg5trk0d.99a/

and paste back the results.

I’ve managed to reproduce this locally, it would seem to be an issue with having %20 in the path (could you rename your project folder (with unity closed) to “Stealth Adventure” or “StealthAdventure” which should resolve the issue. We will look at fixing this in a future version of burst.

That fixed it! I pulled a repo down and didn’t even question it. Clearly I didn’t realize what trouble spaces can be so many years ago when I created the project.

Thanks a ton!
