    I do everything according to the Build qt6 from git manual. Firstly, when running init_repository ninja says path too long. I set long paths in the registry (I use Windows 11), and also changed the setting in the policy (gpedit.msc), but this did not give results. The last time I tried to build 6.8.0 qt, but also could not. (Initially wanted 6.9.0) and earlier I built 6.9.0 and 6.7.2, but after reinstalling Windows I had to build again.

    I could not solve the problem with path too long, and tried to build all this. He almost got it all together, but stopped at a mistake:

ninja: build stopped: subcommand failed.

    The errors were with assimp, in quick3d and qt3d, in the 3rdparty/assimp/src folders. I decided to download a later version of assimp from github, 5.4.3 and 5.4.0, but none of this gave results. It can't find the __imp__fstat32 symbol.

    I don't know what to do anymore, so I decided to write here

    On the previous system this was not the case (I also used Windows 11 before)

    About the tools:
    I use mingw 14.2.0 downloaded via msys2.
    cmake version 4.0.0-rc2.
    git 2.48.1.windows.1
    ninja version 1.12.0

    configure error:

    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'

To configure and build other Qt modules, you can use the following convenience script:
        C:/Qt/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.

    @qtenjoyer said in I can't build any version of qt because of assimp:

    mingw 14.2.0 downloaded via msys2.

    Please use the minge version provided by the Qt installer. Esp. don't use msys in any way.

      Hi All. I have been facing the same problem of "qtenjoyer", so I tried to use "C:\Qt\Qt5.12.12\5.12.12\mingw73_64" instead of msys2 but the configure.bat script ends with ERRORS as below. Is it maybe related to a too old version of QT5?

        @Alec_Star What MinGW version do you use? (no, C:\Qt\Qt5.12.12\5.12.12\mingw73_64 is not the installation location of the MinGW compiler, it is in the tools subfolder).

          Sorry, you are right. That was just my terminal point of commands.
          The version is the one installed with Qt5.12.12 installer.

          C:\Tmp\qt6-build>mingw32-make --version
          GNU Make 4.2.1
          Built for x86_64-w64-mingw32
          C:\Tmp\qt6-build>gcc --version
          gcc (x86_64-posix-seh-rev0, Built by MinGW-W64 project) 7.3.0
          C:\Tmp\qt6-build>g++ --version
          g++ (x86_64-posix-seh-rev0, Built by MinGW-W64 project) 7.3.0

            @Alec_Star This is a very old MinGW version.
            How did you install it?
            You should simply install MinGW using Qt Online Installer or Qt Maintenance Tool.

              @jsulm I simply installed by the offline qt package "qt-opensource-windows-x86-5.12.12.exe".
              Maybe it is a too old version (2018) to compile qt6?

                @Alec_Star Why would you use a package from Qt 5.12 to build Qt6?

                  @Alec_Star Yeas, you should install more recent MinGW. If you don't need Qt5.15 uninstall it and install Qt6 including MinGW.

                    @JonB Well, just because I had that one already installed and i did a try. Anyway, thanks I will give a try with a newer version of qt6.

                      @Alec_Star For the record, Qt supplies a MinGW version, use the one which comes with whichever Qt version you are building.

                        @JonB For the record, I download the last Qt6 environment and I compiled the Qt6 source code without any problem. Thanks for the support.
