How to compile 32 bit with Qt X64 bit on Win10 X64?

[Christian Ehrlicher]

Download Qt 5.12 32Bit, compile it with a 32bit compiler and deploy it...

Hi,
Thanks but this is not a easy solution. I'm searching the other way...

Hi,

That is the easy solution. You can't run a 64bit application on a 32bit version of Windows.

You can use a VM running the 32-bit OS and install Qt 32 bit with the 32 bit compiler, so not to spoil your current 64 bit development environment. It's not that difficult...

Follow @Christian-Ehrlicher suggestion please, it'll save you time and headaches.

Dear @SGaist
I guess I found a way. I install MinGW by MintenanceTool on same Qt. Now it's OK but unfortunatelly I used webengine widgets and I faced below error massage!
Why?...

:-1: error: Unknown module(s) in QT: webenginewidgets

Hi
On windows, webengine is not available for mingw as it cant compile it due to it being based
on Chromium.

Hi @mrjj,
We may decide running code depends on platfom,

 #ifdef Q_OS_LINUX
            serial->setPortName("ttyUSB0");
        #else
            #ifdef Q_OS_WIN
                serial->setPortName("com4");
            #endif
        #endif

Is there any way to get this case depends on VC or MinGW choice?

Hi
Well mingw defines

__MINGW32__ or __MINGW64__
