Error during building Qt6 + MSVC2019

[freedbrt]

I'm trying to build latest Qt6 dev build for windows.

Configure summary:
Building for: win32-msvc (x86_64, CPU features: sse sse2)
Compiler: msvc 19.28.29336.0
Windows 10

and i've got next error, in this file, and in several others with the same error (in this module)

qtquickcontrols2\src\quicktemplates2\qtquicktemplates2plugin.cpp(87): warning C4138: '*/' found outside of comment

This happened because there is a flag /WX, which means treat warnings as an error.
At qtquickcontrols2\src\quicktemplates2\qtquicktemplates2plugin.cpp(87) line source code have next code:

void QtQuickTemplates2Plugin::registerTypes(const char */*uri*/)

And visual studio marks this as a warnings. Can please help me anyone, how can I fix this? How do disable /WX flag, or is there another way out?

Hi,

As a workaround you can either uncomment the parameter name or just remove it.
