Configure Qt for WebAssembly seems to be stuck at 'Info: creating stash file' forever.
-
I am interested to learn about Qt WebAssembly and stared going through the steps from the Qt for WebAssembly. I have configured the emscrripten properly and able to build the helloworld example per the emsdk documentation.
I have pulled the source code for Qt5.12 modules below, in to a directory.
git clone https://code.qt.io/qt/qtbase.git
git clone https://code.qt.io/qt/qtdeclarative.git
git clone https://code.qt.io/qt/qtwebsockets.gitI have setup the emsdk environment and tried to configure the Qt for wasm platform as mentioned in the document. the process seems to be stuck at

Am I missing something here ?
-
Have you tried 5.13 branches?
-
Did you run the examples found here :
https://github.com/msorvig/qt-webassembly-examplesPlease tell me how did you configure Qt.
Normally qt build takes more than 10 hours , atleast for me.
and your configuration command seems to miss modules
./init-repository -f --module-subset=qtbase,qtdeclarative,qtwebsockets,qtsvg,qtquickcontrols,qtquickcontrols2,qtgraphicaleffects
./configure -opensource -confirm-license -xplatform wasm-emscripten -release -static -no-feature-thread -nomake examples -no-dbus -no-ssl -no-qml-debugtry this ..
-
@Izza I think you should take into consideration that @chaithubk is on Windows. I do not think your suggested configure command line will work in this case? Nevertheless, I find some of your options interesting. Too bad it takes so long to get a build done.

For Windows, the platform win32-g++ is required. You also need sed in your path.

As well, Qt versions need a specific version of emscripten, as the pace of emscripten features outpaces Qt, and using a newer emscripten often will not work.
For Qt 5.12, emscripten 1.38.16 is recommended.
