How to build Qt 6.0.0 on Windows with VS2019 from source

[vlado.vesely]

I'm trying to compile Qt 6.0.0.
Compilation always failed on: The moc executable "SRC:/qtbase/bin/moc.exe" does not exist.

I unzip sources to directory w:\qt\6.0.0
Run below script.

call "C:\Program Files (x86)\Microsoft Visual Studio\2019\Professional\VC\Auxiliary\Build\vcvarsall.bat" x64

SET PATH=w:\Qt\6.0.0\qtbase\bin;w:\Qt\6.0.0\gnuwin32\bin;%PATH%
SET PATH=C:\Perl64\bin;%PATH%
SET PATH=C:\Users\vlado\AppData\Local\Programs\Python\Python36;%PATH%

set path >qt_conf_1.log 2>&1

call W:\qt\6.0.0\configure.bat -debug-and-release -prefix W:\qt\6.0.0_i -platform win32-msvc -opensource -confirm-license -skip webengine -nomake tools -nomake examples -nomake tests -opengl desktop -force-debug-info -optimize-size -no-pch -make-tool jom -qt-zlib -qt-pcre -qt-libpng -qt-libjpeg -qt-freetype >qt_conf.log 2>&1

echo nmake
cmake --build . --parallel >qt_comp.log 2>&1

Configuration output:

+ cd qtbase
+ W:\qt\6.0.0\qtbase\configure.bat -top-level -debug-and-release -prefix W:\qt\6.0.0_i -platform win32-msvc -opensource -confirm-license -skip webengine -nomake tools -nomake examples -nomake tests -opengl desktop -force-debug-info -optimize-size -no-pch -make-tool jom -qt-zlib -qt-pcre -qt-libpng -qt-libjpeg -qt-freetype

WARNING: QDoc will not be compiled, probably because libclang could not be located. This means that you cannot build the Qt documentation.
 Either set CMAKE_PREFIX_PATH or LLVM_INSTALL_DIR to the location of your llvm installation. On Linux systems, you may be able to install libclang by installing the libclang-dev or libclang-devel package, depending on your distribution. On macOS, you can use Homebrew's llvm package.
WARNING: Clang-based lupdate parser will not be available. LLVM and Clang C++ libraries have not been found.

Qt is now configured for building. Just run 'cmake --build . --parallel'

Once everything is built, you must run 'cmake --install .'
Qt will be installed into 'W:/qt/6.0.0_i'

To configure and build other Qt modules, you can use the following convenience script:
        W:/qt/6.0.0_i/bin/qt-configure-module.bat

If reconfiguration fails for some reason, try to remove 'CMakeCache.txt' from the build directory

[kkoehne]

I assume you're using CMake 3.18.2 . This version has known issues with the Multi-Config Ninja features that we use for the -debug-and-release builds, see e.g. https://bugreports.qt.io/browse/QTBUG-88015.

So either update CMake, or do not do a -debug-and-release build.

[vlado.vesely]

@kkoehne Thank you very much. I updated (copy) a newer version of CMake and it works.
