[antlr-interest] Trying to modify the getting started field guide to C++

[Philippe Lavoie]

The following grammar file generates this error

E:\projects\morphy>java antlr.Tool basic.g
ANTLR Parser Generator   Version 2.7.2   1989-2003 jGuru.com
basic.g:12:5: expecting ASSIGN_RHS, found ':n:NAME
        { std::cerr << "Hi there, " << n.getText() << std::endl;}
    ;'
basic.g:3:1: rule grammar trapped:
basic.g:3:1: expecting SEMI, found '}'
Exiting due to errors.


Any idea why going from Java to C++ causes this error?

Thanks

Phil
