Many of the components were not compilingm,because bld.inf had undefined flag #ifdef RD_CUSTOMIZABLE_AI. All the flags removed now. Components do not compile right away. E.g. many icons are missing and need to be copied from Symbian3. See example from MCSPlugin. Shortcut plugin does not need to be compiled as MCSPlugin replaces it.
