earlier today someone mentioned that if GTKMM_ATKMM_ENABLED is #defined when building the Gtkmm DLL, it must also get #defined in anything which uses that DLL. That makes a lot of sense - because otherwise, certain objects (e.g. class Widget) will have different sizes in different modules. To me, that sounds like a promising explanation for this 'delete' problem. [...] I'll try rebuilding everything, making absolutely sure that GTKMM_ATKMM_ENABLED is #defined in all modules. Fingers crossed, that might solve the problem! codekiddy - the secret to making this work is that every module which uses gtkmm MUST know the status of GTKMM_ATKMM_ENABLED. In theory, gtkmmconfig.h should achieve this - but to be absolutely certain (for testing purposes) I made use of MSVC's /FI option (ForceInclude). I used it to force include a specific header file in which I'd #defined GTKMM_ATKMM_ENABLED. This guarantees that every compiled source file will know about that #define. Simply making the change in gtkmmconfig.h should achieve the same thing but it looks like that isn't quite working properly. In fact, I know it isn't working properly - because after I used the /FI option, everything which previously linked to gtkmm now also needed to get linked to atkmm. So the problem is that something somewhere needs to be #including gtkmmconfig.h but is failing to do so. My guess would be 'gtkmm/window.cc' (maybe??) Perhaps even anything that references a Widget? If it forgets to #include widget.h the wrong size might be assumed for 'Widget'. Admittedly I'm guessing here - but it does seem like there's an important #include missing somewhere :-( John |
