@Wolfgang,
Thanks for your helpful comments.
Please review the build.log. This is already done without needing these flags.
You right in case of --enable-introspection flag. (Build introspection support: yes) is because you have BuildRequires: gobject-introspection-devel
But you didn't build with Startup notification support.
Why?
