Hi Norman,

thank you for quick replay , acctualy I added 'Genode::' as prefix for 'Meta::' and 'Rpc_functions' respectively. and i got different error now

error: typedef name may not be a nested-name-specifier

i will add the file here . i am sure that i miss some thing

maybe, your interface is not declared within the 'Genode' namespace?
Could you try to specify 'Genode::' as prefix for 'Meta::' and
'Rpc_functions' respectively?
