Here’s a new howto explaining the steps to compile, install and enable the gnome-globalmenu-0.7 series from trunk on your desktop.
This has been tested on Ubuntu intrepid ibex but it should work on hardy too. It should also work with other distributions, except for the first step (dependencies install).
Globalmenu works with “real” gtk applications. That means globalmenu will not work with firefox and openoffice.
Big thanks to rainwoodman and lviggiani for their awesome work on this very useful application.
