Well, you're compiling it as a C++ program, not a C program. C++ is more strict about type-checking in parameters passed to functions. Unless there's a reason you're using C++, rename the file to .c and compile with a C compiler. Otherwise, you'll have to add extra casts for the function pointers passed to the functions noted in the error message. (In all fairness, though, g_signal_handlers_unblock_matched() should take a GCallback as the 6th param, not a gpointer. C just doesn't care, while C++ does.) -brian _______________________________________________ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
