Re: compiling gtkmm with atkmm support fails in implementor.cc

[codekiddy <codekiddy gmail com>]

I wonder why the heck, but it doesn't work for me.

I recompiled gtkmm 3 times already at no avail.

Used your suggestion to force include a header with following contents:

#ifndef GTKMM_ATKMM_ENABLED

     #define GTKMM_ATKMM_ENABLED 1

#endif

I set in Common properties > C\C++ > Advanced > Force Include File > "the name of the file".h

This didn't work

then I went on and defined preprocessor macro in

Common properties > C\C++ > Preprocessor > Preprocessor definitions > GTKMM_ATKMM_ENABLED 

Rebuilt solution clean, and no luck!

I also defined that macro in gtkmmconfig.h as well. recompiled and it still does not work.

I also triple checked if gtkmmconfig.h has this macro defined in installation directory where other test project search for headers.

Test project include this header by force as well.

What am I doing wrong here?

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!

Hi Kjell.  I just found some time to try the above strategy and guess what...  that fixed it !!

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  :-(
