Thanks Hans for your reply. I would like to know if it supports Windows, Linux and major UNIX systems (Sun, HP, IBM). If I want to try Bison on a particular system, what settings do I need to make before trying to run it. Thanks, YiQing Yang -Original Message- From: Hans Aberg [mailt

RE: re-entrant parser scanner "%pure-parser g++

Hi David, I tried before your solution using a common .h file for .lex and .yacc, however since I'm using "%pure-parser" in my .yacc, the YYSTYPE used in "yylex" proto is not visible to the .h itself. Any help (more verbose please) ? Here is the yylex proto: #define YY_DECL int yt_unique_datalo

re-entrant parser scanner "%pure-parser g++

Hi, I'm using flex 2.5.4a, bison 2.3 & g++ 3.4.5. I added "%pure-parser" directive to my .yacc in order to produce a re-entrant parser and I compile my .lex.c with g++ in order to get a re-entrant scanner (as written in flex manual). I defined YY_DECL as follow (in .lex prelude): %{ //Head

Re: parsing compressed files with flex & bison

Flex was not built to generate lexers for essentially binary files, though you may try it. And one can easily pipe streams under UNIX- like OS's. Hans Aberg On 28 Dec 2006, at 14:27, Aïmen Troudi wrote: I want to parse files in one pass for 2 reasons : 1- size of (5) files is important

POSIX threads %union YYSTYPE

Hi Hans, You are right, "YYSTYPE" is defined in .yacc.h as "%union" directive. Best regards, AnL. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Hans Aberg Sent: jeudi 28 décembre 2006 13:16 To: Anouar LACHHEB Cc: Help Bison Subject: Re: (no subject) O
