Uncaught TypeError/RuntimeError on Chrome/Opera + infinite loading wheel on Firefox and IndexDB related error

[nooxouille]

Hello people!
4.24 HTML5 fork here, build went well (either on dev/shipping configuration).
When tested on localhost (XAMPP, windows) with both Opera and Chrome I am getting 2 different errors:

Opera :

Uncaught TypeError: Module._emscripten_futex_wake is not a function

Chrome :

Uncaught TypeError: Module._emscripten_futex_wake is not a function
Uncaught RuntimeError: float unrepresentable in integer range

And the infinite loading wheel on Firefox :

That wheel come with an error message when IndexDB storage is check in the settings (I have tried with it check/uncheck) :

Failed to store file wasmModule to IndexedDB, error: DataCloneError: The object could not be cloned.

have you merged latest upstream to 4.24.3?

• if so, this issue is being tracked in issue "Uncaught TypeError: Module._emscripten_futex_wake is not a function" While running #14

if not, have you built for multi-threading?

• 4.24 has runtime crash (like you see above) when built single-threaded
• this was documented in the HowTos:
  • https://github.com/UnrealEngineHTML5/Documentation/blob/9785cbaff57c19cc7e863fdf0268161848c37d6b/Platforms/HTML5/HowTo/README.1.emscripten.UE4.HTML5.md#window-2
  • (see last line in that section)

Hey!
I have not merged on 4.24.3 as I am still on 4.24.0.
The build was multi-threading, indeed (as advised in the guidelines)

[nickshinpho]

is this developer build? (people have reported that shipping does not work -- also in #14)

[nickshin]

also, can you test with chrome canary and firefox nightly -- i've just confirmed that those two are working. (albeit that was tested with the 4.24.3 i just pushed up...)

[nooxouille]

is this developer build? (people have reported that shipping does not work -- also in #14)

I tried with both (dev & ship).

@nickshin

Nightly:

ReferenceError: SharedArrayBuffer is not defined

Canary

Uncaught TypeError: Module._emscripten_futex_wake is not a function

Might try to go on 4.24.3

Firefox currently requires an extra flag for SAB: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/SharedArrayBuffer#Browser_compatibility

I am having the same problem with 4.24.3 (or whatever the newest version on this github page is)

[nickshinpho]

@nooxouille @fllyingburritos are you both still seeing this multi-threading error issue?

[nooxouille]

@nickshinpho Hi!

I should have updated it but I moved on something else as the errors were blocking me (Unity + webGL). I haven't tried again lately.
