Error: no type named 'VarDictionary' in namespace 'pp' using PNaCl

[Tal Glozman]

Can someone explain me why am I getting this compile error

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

I'm tying to set a dictionary in the function

    virtual void HandleMessage(const pp::Var& message) {
    }

I copied the example from the bottom of this Google page https://developer.chrome.com/native-client/devguide/coding/message-system

and tried something simple like 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 I compile the code i get the error message for the `pp::VarDictionary dictionary;` however no problem with the `pp::VarArray an_array;`

I'm using this Makefile

Problem solved I needed to add the

#include "ppapi/cpp/var_dictionary.h"

at the beginning of my c++ code
