    i followed this link' instructions to build Qt 6.0.0 from qt-everywhere-src.zip, but i get these errors:
    https://doc.qt.io/qt-6/windows-building.html

    I am using MSVC 2019.

    error:

    I'm not very familiar with Windows build environment, but is that OK?
    I mean, it looks like the 64 bit version of cl.exe is being used, but it's strange that the Visual Studio installation went to the x86 folder, as a 32 bit application?

    Could you please describe your environment? i.e. Windows OS version and platform, same for Visual Studio.

            This looks strange. This should be the call to the compiler, but instead vcvars64.bat is called. Can you show your script you created as described in the link (qt6vars.cmd)?

              @Lemat I think that path is correct. Visual Studio itself is a x86 application, but it has compiler which generates x86_64 binaries.

                  should i set a real compiler path in the system environment variable CXX ?? i don't know the real compiler file name. my actual Qt 5.15.2 has detected it automatically. i am looking in her settings to find the compiler file name, but nothing.

                    @Lemat I don't think so. It should work as described on that web page. I don't know why it doesn't work for you.

                          Hi,

                          IIRC, cmake 3.19.2 or newer is recommended but I don't have the source at hand.

                              You should update your cmake version.

                                        What did you do to ensure a clean state ?

                                          I Installed Qt 6.0.1 with the online Installer. Too bad for me. Many features such as QWebEngine are removed

                                          Time to elevate.
