Webassembly: no binaryen method suceeded

Target Platforms Web
1

Hi,

i just downloaded the Unity Beta (5.6.0b3) and tried to use the new feature in the PlayerSettings for a WebGL Build: Webassembly (Experimtental). My Test-Project is a simple scene with a camera, directional light and a cube.

The build crashes when the progressbar says: Building native binary with IL2CPP…

I attached the Editor.log, but i think the responsible exception for the crash is:
System.NotSupportedException: Need Unity source to use node

Is there anything i could do to solve this? Thanks!

I’m sorry i just noticed this Thread:

I downloaded Unity 5.6.0b2 and the build runs fine now. But when i start the build in the Browser i get the following error:
trying binaryen method: native-wasm (printErr @ UnityLoader.js:3)
failed to compile wasm module: Error: WebAssembly.Module(): Wasm decoding failedResult = expected version 0c 00 00 00, found 0d 00 00 00 @+4
(printErr @ UnityLoader.js:3)
Uncaught no binaryen method succeeded. consider enabling more options, like interpreting, if you want that: WebAssembly · emscripten-core/emscripten Wiki · GitHub

Any ideas what i can do to fix this?

Thanks,

This is your problem:

 Wasm decoding failedResult = expected version 0c 00 00 00, found 0d 00 00 00 @+4

While Wasm is still in development, the specification is still evolving, and the format changes on a regular base. Unity 5.6 currently emits WASM version 0xd, but your browser seems to support the older 0xc. You should probably update to a newer Nightly/Canary build.

Thank you! It works in Chrome Canary.
