@Crazy-Sage said in How to build Qt with clang under windows?:

Clang 7.0.0

And you're sure this ancient compiler supports all MSVC commands when you use clang-cl. What do you think you will gain when you compile Qt with clang-cl at all?

Yes @JonB, it requires depencencies but this is not a problem. I will install this automaticly after users choice.

You can find them under:
LTS RELEASE
https://dotnet.microsoft.com/download/dotnet-core/3.1

Current release
https://dotnet.microsoft.com/download/dotnet/5.0

Note: .net CORE works with Linux, macOS und Windows.

@BikashRDas said in QNetworkConfiguration and QNetworkConfigurationManager alternatives for Qt 5.15.2:

I am using Qt 5.15.2 enterprise edition

Is that version backed by a commercial license from Qt?
If so, you may want to ask for help from Qt support directly

@mujeek Thank u, I run into this error, and this fixed it. Not all heroes wear a cape.

I'm using Qt Creator 4.14.0 and Qt 5.15.2

dunno if you managed to resolve your problem in the meantime,
but I had a similar error (under macOS and emscripten 1.39.17):

After downloading and installing everything, I ran emsdk_env (which should generate the ~/.emscripten file in the user folder, if I remember correctly)

But it seems, that Qt Creator could not resolve the var for the defined emsdk_path

emsdk_path = os.path.dirname(os.environ.get('EM_CONFIG')).replace('\\', '/')

so I replaced all the placeholder with the explicit path:

emsdk_path = '/Users/myuser/Documents/Programming/emsdk'

I also added

COMPILER_ENGINE = NODE_JS JS_ENGINES = [NODE_JS]

at the bottom (not sure though if that was needed)

After restarting Qt creator the compiler and toolkit for WebAssembly wer successfully recognized.

@SGaist That was my problem. I compiled the libraries with MinGW 32 while my Qt's is MinGW 64. I changed the compiler and the problem is solved.
Thanks for the help.

Hi author here,

Now there's a dedicated guide available to follow for cross-compiling latest QT for any Raspberry Pi Model or Version with mentioned GCC toolchains:

@lorn-potter thanks for your command.
I love working with QT. If WASM would be working, a complete new world would open for us. The main thing what annoys me is that I can not find a good manual/guide to get wasm running on linux. I hope somebody can point me in the good direction. I'm probably just missing the needed information/knowledge, but I really want to learn!
