Hi, do you have the suitable mingw32 version for qt6?Does it go with your Qt6 Version?

WARNING: Basic cpp/winrt support missing. Some features might not be available.
WARNING: QDoc will not be compiled, probably because clang's C and C++ libraries could not be located. This means that you cannot build the Qt documentation.
You may need to set CMAKE_PREFIX_PATH or LLVM_INSTALL_DIR to the location of your llvm installation.
Other than clang's libraries, you may need to install another package, such as clang itself, to provide the ClangConfig.cmake file needed to detect your libraries. Once this
file is in place, the configure script may be able to detect your system-installed libraries without further environment variables.
On macOS, you can use Homebrew's llvm package.
You will also need to set the FEATURE_clang CMake variable to ON to re-evaluate this check.
WARNING: QDoc will not be compiled because the QmlPrivate library wasn't found.
WARNING: Clang-based lupdate parser will not be available. LLVM and Clang C++ libraries have not been found.
You will need to set the FEATURE_clangcpp CMake variable to ON to re-evaluate this check.

@rahmanih qt6 is using mingw 11, but you are trying to build with mingw 13.That could be the issue.Did you read the tutorial i sent?

[rahmanih]

@Ronel_qtmaster

the 13.2.0 is the version of GCC not the MingWin.
anyway it seems to be O.K now:

• download the mingwin from https://winlibs.com
• use PowerShell and not Git BASH to run the build command.

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 'C:/Qt/Qt-6.6.3'

To configure and build other Qt modules, you can use the following convenience script:
        C:/Qt/Qt-6.6.3/bin/qt-configure-module.bat

If reconfiguration fails for some reason, try removing 'CMakeCache.txt' from the build directory
Alternatively, you can add the --fresh flag to your CMake flags.

-- Build files have been written to: C:/temp/qt6_min/qtbase
PS C:\temp\qt6_min\qtbase> cmake --build .

@rahmanih said in Can't build QT6 on Windows using MingWin54:

Git BASH to run the build command.

You must not have any MSYS related stuff in your PATH - otherwise the build tools might pick them up (due to same name) and it will fail. You can see the problem already in your first output if I'm correct: "@C:/temp/qt6_min/qtbase/src/3rdparty/libjpeg/JpegPrivate_syncqt_args" - the forward slashes (but I might be wrong)
