[Interest] wasm build of Qt 6.1.x ?

[David Skoland]

Hi,

Have you tried using cmake? It might work, even if wasm won’t be officially supported again before 6.2. Compiling qt from current development HEAD and using that to cross-compile to wasm should work, though, if living on the bleeding edge is ok :)

Cheers,

David Skoland

Hi,

I have built a wasm version for Qt 5.14.2 successfully and use that to build various test applications.

I have been trying to cross compile to wasm_32 using emscripten for Qt 6.1.0.
I have not been successful.

Has anyone been able to do so ? Which version of emsdk was installed and activated for the build to be successful ? I have tried both 1.39.8 and 2.0.14 without success

The build does complete but when I use the qmake from the wasm build, there was a link error looking for freetype and OpenGL amongst other errors, has anyone come across that error ?

I also noticed that the required wasm_shell.html was not installed in the expected place by qmake.

I had a look at Qt 6.1.1 release notes hoping to find out if there was any mention of wasm/webassembly but did not see any.

Cheers
