EmscriptenApplication.js:35 missing function: emscripten_get_sbrk_ptr

Hmm, this seems to be the culprit. Maybe caused by a newer emscripten version...

Try enabling assertions, maybe you'll get more info:

target_link_options(MyApplication PRIVATE
    # Set debugging flags (assertions and demangle)
     $<$<CONFIG:DEBUG>:-s ASSERTIONS=1 -s DEMANGLE_SUPPORT=1>)
Squareys commented 4 years ago

Looking at Emscripten's issues, especially https://github.com/emscripten-core/emscripten/pull/9397, it seems like this sbrk stuff is some pretty bleeding edge feature, you may want to go back to 1.38.46 or even earlier.

mosra commented 4 years ago

I have to admit the new Emscripten versions don't work for me very well (complaining about Clang version mismatch and whatnot), so I'm personally at 1.38.38 (and binaryen 87 to go with that).

I'll look at this before release, but so far it seems it's one of those "emscripten is broken" days ... let's wait until things settle down there :D

Have tested with emsdk 1.38.30 and 1.38.46, both with error:

@linuxaged did you get any further with this? I wasn't able to reproduce on my side.

Keeping this open until we figure it out, but since it seems to be that Emscripten is to blame I don't think it's blocking the 2019.10 release.

mosra commented 4 years ago

Nice.

The wasm streaming compile failed is due to the server not knowing about WebAssembly MIME types. It's harmless, AFAIK it only slows down the startup slightly since the browser can't do wasm compilation in parallel to download.

linuxaged commented 4 years ago

by the way, cmake toochain files not included in the bootstrap Emscripten project archive, complete project maybe more friendly to newcomers : >

mosra commented 4 years ago

It's a Git submodule and the ZIPs created automagically by github don't include these :/ Not sure how to fix that (besides manually putting all files there..).

mosra commented 4 years ago

Anything left to be done here? :)

linuxaged commented 4 years ago

fine to close
