Qt 5.13.2 and recommended emscripten

[Boris613]

I am trying to build Hello world on MacOS using Qt 5.13.2, binary package. I can build recommended emscripten sdk 1.38.27 from source because it is no longer available precompiled.

I suspect that my errors are related to this,
no symbols
wasm-ld: error: main.o: machine type must be wasm32
wasm-ld: error: moc_main.o: machine type must be wasm32
wasm-ld: error: main.o: machine type must be wasm32
wasm-ld: error: moc_main.o: machine type must be wasm32
wasm-ld: error: moc_main.o: machine type must be wasm32
wasm-ld: error: main.o: machine type must be wasm32

I am getting the same errors from command line and from QtCreator, using emsdk 1.39.3

Is it a way to determine whether it is emsdk error or another issue?

The recommended precompiled SDK download is 1.39.3 (b024b71038d1291ed7ec23ecd553bf2c0c8d6da6).

To install/activate it, use one of:
latest [default (llvm) backend]
latest-fastcomp [legacy (fastcomp) backend]

Those are equivalent to installing/activating the following:
1.39.3
1.39.3-fastcomp

All recent (non-legacy) installable versions are:
1.39.3
1.39.2
1.39.1
1.39.0
1.38.48
1.38.47
1.38.46
1.38.45
1.38.44
1.38.43
1.38.42
1.38.41
1.38.40
1.38.39
1.38.38
1.38.37
1.38.36
1.38.35
1.38.34
1.38.33

The additional following precompiled SDKs are also available for download:
sdk-1.30.0-64bit
sdk-1.34.1-64bit
sdk-1.35.0-64bit**

Currently, we are still recommending emscripten 1.38.27 or 1.38.30 for threaded builds. These are what the Qt WebAssembly binaries are built with, and you will need to use the same emscripten version.

Thanks Lorn. It was easier to rebuild Qt at the end, and it solved the issue.
