This is the code that produces the error. It's identical to the one I posted before, except at the beginning of void.loop() this line has only one *.
lv_obj_t *ui_Arc_pointer;
The error is the same with the * adjacent to the t, to the u, or beween spaces.
Sorry I haven't found out a way to paste code with line numbers
