    Question Is Python 2 still a must to build webengine?

    [LIST]
    [*]Qt 5

    Qt Code:
    1. Note: Also available for Linux: linux-clang linux-icc

    3. Note: The following modules are not being compiled in this configuration:
    4. webenginecore

    18. Qt is now configured for building. Just run 'gmake'.
    19. Once everything is built, you must run 'gmake install'.
    20. Qt will be installed into '/opt/qt/5.15.11'.

    Qt Code:
    1. WARNING: QtWebEngine won't be built. Could not find all necessary libraries for qpa-xcb support. X11:YES LIBDRM:YES XCOMPOSITE:YES XCURSOR:YES XRANDR:YES XI:YES XPROTO:YES XSHMFENCE:NO XTST:YES
    2. WARNING: SensorFW support currently not enabled with cmake

    6. Qt is now configured for building. Just run 'cmake --build . --parallel'
    7.  
    8. Once everything is built, you must run 'cmake --install .'
    9. Qt will be installed into '/opt/qt/6.6.0'
    10.  
    11. To configure and build other Qt modules, you can use the following convenience script:
    12. /opt/qt/6.6.0/bin/qt-configure-module
    13.  
    14. If reconfiguration fails for some reason, try removing 'CMakeCache.txt' from the build directory
    15. Alternatively, you can add the --fresh flag to your CMake flags.

    Hi,

    in the first line "WARNING: QtWebEngine won't be built. Could not find all necessary libraries for qpa-xcb support..." it is complaining about XSHMFENCE:NO, so I think installing libxshmfence and the corresponding development package will help. This does not look like a problem with python to me.
