WebAssembly Build Failing

bigbrainz · February 6, 2017, 11:48pm

I can make a Developer build just fine, but a normal build gives me this error:

Running 5.6.0b5

Turning off code stripping doesn’t help.

Sometimes I only get this error:

Ah, I see 5.6.0b6 is up. I’ll try that.

bigbrainz · February 7, 2017, 4:26pm

No luck. Same error in 5.6.0b6

bigbrainz · February 7, 2017, 6:31pm

Trying 5.6.0b7

bigbrainz · February 7, 2017, 7:11pm

Argh. No luck. I can successfully make a WebAssembly build if I just open up an empty project, so looks like I’ll have to track down what in our project is triggering that problem. Strange. It runs all the way through the build process btw before it fails. For example it completes “Compile asm.js module” and it LOOKS like it completes “Compile WebAssembly module,” but then it fails after sitting on that for a while.

Might be the same error I’m getting (same error code -1073740791). Reported it last week with no response yet (876807).
For me the asm2wasm process crashes when reaching 2GB ram usage.

Marco-Trivellato · February 7, 2017, 10:17pm

This is indeed a memory problem specific to Unity for Windows. We have a fix and will land to 5.6 pretty soon.

bigbrainz · February 8, 2017, 5:18pm

Excellent! The sooner the better so I can start hammering on WebAssembly as much as possible while we’re still in Beta.

bigbrainz · February 17, 2017, 10:29pm

Still no luck still in 5.6.0b9 . . .

PieterAlbers · March 6, 2017, 11:09am

No luck in 5.6.0b10 either

Schubkraft · March 6, 2017, 4:32pm

Fixes are in b11. Stay tuned.

bigbrainz · March 8, 2017, 11:17pm

Build successsfully in 5.6.0b11!!

I then got a different error in the browser, but I’m still troubleshooting that one to see if it’s on my end. Yay!!

Pontik · March 10, 2017, 7:40am

Build is successfull, but browser stop working on LinkError: imported Memory with incompatible size

Pontik · March 10, 2017, 8:39am

With 128 mb memory size it has worked for me! But i am not realy sure it use webassembly and not the fallback to asm.js…

I got quite a few errors in Firefox until I updated to 52.0.
Canary launched successfully first try.
Chrome also launches in version Version 57.0.2987.98 beta (64-bit).

I’m still getting quite a few errors, but it’s still able to run. I have to sort out which of these errors are a result of moving from 5.4 to 5.6 and which are directly tied to WebAssembly.

PieterAlbers · March 17, 2017, 8:18am

Hi all,

I was able to make a build in b11, bunch of issues though - but to be expected.

However, I always get a asm2wasm.exe crash when building with full exceptions on.

Has anybody experienced this as well? Is there something I am missing?

-Pieter

Schubkraft · March 17, 2017, 1:40pm

Got an error with WASM with full exceptions too. Will log a bug but please file a report with logs regardless so we can check if we’re seeing the same.
