[antlr-interest] Antlr v3 Cannot compile C++ generated grammar

[Sebastien Van Cauwenberghe]

Hi All,

I made a grammar for Antlr v3 C++ and I got lots of compile error regarding
a non-existing type in the parser...

Below, you will find the "config" part of my grammar and the errors I
face...
--------------

grammar ccc;

options
{
backtrack = true;
memoize = true;
language=Cpp;
output=Ast;
}

@lexer::namespace{cccNs}
@parser::namespace{cccNs}

@lexer::traits
{
    class cccLexer;
    class cccParser;
    typedef antlr3::Traits< cccLexer, cccParser > cccLexerTraits;
    typedef cccLexerTraits cccParserTraits;
}

Did someone have the same problem with the C++ target or did I fail
something ???

Thank you in advance for your support...
