Build simple QML on WebAssembly
-
Hello everyone,
I'm trying to build my first app on WebAssembly.
My setup:- Windows 10
- Qt 5.15
- emsdk install/activate sdk-fastcomp-1.39.7-64bit
- corrected .emscripten config file in home directory, so Qt Creator could find emscripten
But I stuck with the same build/compile error:
