In gtkstatusiconh.inc there is a type definition PPGdkScreen = PGdkScreen; It is most likely a bug. I guess it should be PPGdkScreen = ^PGdkScreen;
It is used for : gtk_status_icon_get_geometry : function(status_icon:PGtkStatusIcon; screen:PPGdkScreen; area:PGdkRectangle; orientation:PGtkOrientation):gboolean; cdecl; which is used in LCL function TGtk2TrayIconHandle.GetPosition: TPoint; gtk_status_icon_get_geometry(FStatusIcon, @AScreen, @AArea, @AOrientation); where AScreen: PGdkScreen; FPC option -Sy revealed the error. Otherwise it would be very difficult to notice. Incidentally there has been problems with TrayIcons in LCL-GTK2. I am changing code in Lazarus sources so that it compiles with -Sy. I recommend FPC project does the same. Very useful option! Typically it reveals such hard to find bugs. Please verify if my analysis is correct. If there is no bug then the type name PPGdkScreen is misleading and should be removed. Otherwise I will fix it in LCL sources so that it works also with the current FPC 3.2.2. Regards, Juha
