Hi Mohammed,

the error tells you that name of the type defined via a 'typedef' must
not be prefixed with the name of a namespace. In this case,
'Genode::Rpc_functions' must be just called 'Rpc_functions'. Sorry for
bringing you on the wrong track in my previous email. The prefix is only
needed for type names that you want to use from the 'Genode' namespace
(e.g., 'Genode::Meta::Type_tuple'), not for types defined by yourself.

Cheers
Norman
