compiler error .hh file

[Gilberto Monroy]

Hi everybody.

My name is Gilberto, I use the next tools:



   - Flex: 2.5.35
   - Bison: 3.0.2   ( C++ )
   - OS: Linux  3.5.0-44-generic #67~precise1-Ubuntu SMP Wed Nov 13
   16:16:57 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
   - GCC: gcc (Ubuntu/Linaro 4.6.3-1ubuntu5) 4.6.3



I  use Bison for C++, I get the following problem when I compile with gcc,
I want to know if I am doing something wrong or it is a bug. It seems that
bison duplicates the definition and declaration of a function:

I use variants, the next is on my grammar file:
...
%skeleton "lalr1.cc"
%require "3.0"                    /* The grammar is made to work on Bison
3.0 */
%language "C++"                    /* The output will be a c++ class */
%debug                            /* Debug mode */
%locations                         /* Gives an interface to access location
information */
%defines                        /* */
%define parser_class_name {RcssParser}     /* Name of the class generated
by Bison */

%define api.token.constructor     /* */
%define api.value.type variant    /* Use a variant-based interface instead
of unions */
%define parse.assert            /* Enable assertions */
...
%token <Playmode> BEFORE_KICK_OFF
%token <Playmode> TIME_OVER
%token <Playmode> PLAY_ON
...
%type < Playmode >     playmode
...
%%

...
init:         INIT side NUMBER playmode  { driver.h_init_finished( $2, $3,
$4 ); }
;
playmode:    BEFORE_KICK_OFF { $$ = $1; }
        |    TIME_OVER        { $$ = $1; }
        |    PLAY_ON        { $$ = $1; }
;

And the tokens are defined as follows on my lexer file:

...
"before_kick_off"     { return yy::RcssParser::make_BEFORE_KICK_OFF(
BeforeKickOff, loc); }
"time_over"         { return yy::RcssParser::make_TIME_OVER( TimeOver,
loc); }
"play_on"             { return yy::RcssParser::make_PLAY_ON( PlayOn, loc); }
...

I can attach the whole project if you want.

Thanks in advance for the help.
