[Ayatana-dev] Unity build problem - "package 'gdu' not found"

[Bartosz <gang65@xxxxxxxxxxxxxx>]

Hi.

I would like to build unity on Ubuntu 11.10, by follow instruction:
http://askubuntu.com/questions/28470/how-do-i-build-unity-from-source

Unfortunately some package is missing. After typing command "cmake .. -DCMAKE_BUILD_TYPE=Debug -DCOMPIZ_PLUGIN_INSTALL_TYPE=local -DCMAKE_INSTALL_PREFIX=/opt/unity"

I have error:

-- checking for modules 'compiz;nux-2.0 >= 2.0.0;libbamf3;dee-1.0;gio-2.0;gio-unix-2.0;dbusmenu-glib-0.4;x11;libstartup-notification-1.0;gthread-2.0;indicator3-0.4;atk;unity-misc >= 0.4.0;gconf-2.0;libutouch-geis;gtk+-3.0 >= 3.1;sigc++-2.0;json-glib-1.0;libnotify;gnome-desktop-3.0;gdu;unity>=4.0.0'

Do you know how to resolve this error?


Thanks in advance
