try this: ``` macos { contains(QMAKE_HOST.arch, "arm64") { QMAKE_CFLAGS += -mcpu=apple-m1 } else { QMAKE_CFLAGS += -march=native } } ``` it works for me，Apple M2

Just follow this: ``` Q_DECLARE_OPAQUE_POINTER(sqlite3*) Q_DECLARE_METATYPE(sqlite3*) Q_DECLARE_OPAQUE_POINTER(sqlite3_stmt*) Q_DECLARE_METATYPE(sqlite3_stmt*) ```

just because the source of this plugin was origin from qt4/qt5 qsqliteplugin，in qt6，it looks like you should declare opaque pointer before delcare metatype，that is the key point，sorry for my poor...
