如何在树莓派5+ubunut24上编译Qt5.15.15

下载Qt 5.15.15源码包

wget https://download.qt.io/official_releases/qt/5.15/5.15.15/single/qt-everywhere-opensource-src-5.15.15.tar.xz

tar -xf qt-everywhere-opensource-src-5.15.15.tar.xz

cd qt-everywhere-src-5.15.15

打个Qt6不支持libxcbcommon 1.6.0的补丁

编辑源码文件 qtbase/src/platformsupport/input/xkbcommon/qxkbcommon.cpp 在第275行增加几行代码，如下：

        Xkb2Qt<XKB_KEY_dead_greek,              Qt::Key_Dead_Greek>,
#ifdef XKB_KEY_dead_lowline
        Xkb2Qt<XKB_KEY_dead_lowline,            Qt::Key_Dead_Lowline>,
        Xkb2Qt<XKB_KEY_dead_aboveverticalline,  Qt::Key_Dead_Aboveverticalline>,
        Xkb2Qt<XKB_KEY_dead_belowverticalline,  Qt::Key_Dead_Belowverticalline>,
        Xkb2Qt<XKB_KEY_dead_longsolidusoverlay, Qt::Key_Dead_Longsolidusoverlay>,
#endif
        // Special keys from X.org - This include multimedia keys,
        // wireless/bluetooth/uwb keys, special launcher keys, etc.
