[antlr-interest] Re: C++ parser

[geofuntasma]

I'm having the same problem. The message I got exactly at the
beginning is: 

-------------------------------------------------------------------
[@bash][~/ANTLR/C++ Grammar]> java antlr.Tool CPP_parser.g
ANTLR Parser Generator   Version 2.7.3   1989-2004 jGuru.com
CPP_parser.g:1222: warning:nondeterminism upon

CPP_parser.g:1222:     between alt 1 and exit branch of block
-------------------------------------------------------------------

As you can see the ANTLR version I have is 2.7.3 and I've just checked
the grammar and it seems to be the version 2 :

----------------------------------------------------------------
/* 2003
 * Version 2
 * This is version 2 of the C++ grammar definition for ANTLR to 
 *  generate lexer and parser in C++ code updated by
 *  David Wigg ....
----------------------------------------------------------------

However there is no specification for what ANTLR versions supports. So
I really dont know the source of the problem. I wanna add that the
CPPParser and CPPLexer files (.cpp and .hpp) are created. But, when I
tried to do: "gcc CPPParser.cpp", I got all the errors having an
"include CPPParser.hpp" statement in them.

Thanks in advance for your help.
