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

[codekiddy <codekiddy gmail com>]

Phil,

I removed the atkmm import library from linker input and got this unresolved external

error LNK2001: unresolved external symbol "protected: virtual class Glib::RefPtr<class Atk::Object> __cdecl Atk::Implementor::ref_accessibile_vfunc(void)" (?ref_accessibile_vfunc Implementor@Atk@@MEAA?AV?$RefPtr VObject@Atk@@@Glib@@XZ)

John,

Test program can't be more simple then it is:

#include <gtkmm/window.h>

#include <gtkmm/application.h>

int main(int argc, char* argv[])

{

using namespace Glib;

using namespace Gtk;

RefPtr<Application> app = Application::create( argc, argv, "gtkmm.exe" );

Window win;

app->run(win);

}

1. What if somewhere there's a line that says "#define GTKMM_ATKMM_ENABLED 0" ?
2. Is libatkmm being included in your link commands?

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  :-(
