Re: Problem with g++ and GtkItemFactory functions

Hi,

Thanks for the quick reply ... but it doesn't really provide me with a 
solution as far as I can tell:

Am I to provide my own prototype and overwrite the one in 
gtkitemfactory.h?  I'm not sure how I can expect other people to do this 
when downloading and compiling my code.

EG., If I comment out the GtkItemFactoryCallback prototype and replace 
it with the GtkItemFactoryCallback1 prototype, I'm still SOL:

erl_buffer_obj.C: In function `GtkWidget* 
setup_perl_fs_menu(signal_object*)':
perl_buffer_obj.C:59: invalid conversion from `void (*)(signal_object*)' 
to `
  void (*)(void*, unsigned int, GtkWidget*)'
perl_buffer_obj.C:59: invalid conversion from `void (*)(signal_object*)' 
to `
  void (*)(void*, unsigned int, GtkWidget*)'
perl_buffer_obj.C:59: invalid conversion from `void (*)(signal_object*)' 
to `
  void (*)(void*, unsigned int, GtkWidget*)'
perl_buffer_obj.C:59: invalid conversion from `void (*)(signal_object*)' 
to `
  void (*)(void*, unsigned int, GtkWidget*)'
make: *** [perl_buffer_obj.o] Error 1

Is there a solution?
