c++ - No type named 'VarDictionary' in namespace 'pp' using PNaCl -

can explain me why getting compile error

error: no type named 'vardictionary' in namespace 'pp'         pp::vardictionary dictionary;         ~~~~^ 

i'm tying set dictionary in function

virtual void handlemessage(const pp::var& message) { } 

i copied example bottom of google page https://developer.chrome.com/native-client/devguide/coding/message-system

and tried simple this

virtual void handlemessage(const pp::var& message) {     pp::vardictionary dictionary;     pp::vararray an_array;     an_array.set(0, pp::var("string0"));     an_array.set(1, pp::var("string1"));     dictionary.set(pp::var("param_array"), an_array);     postmessage(dictionary);     } 

but when compile code error message pp::vardictionary dictionary; no problem pp::vararray an_array;

i'm using makefile google

you need add header file var_dictionary.h class trying access declared.
