Re: Problem wih yacc/lex

[Hans Aberg]

This is the Help-Bison list, and not a list for help with Yacc or Lex.
Though Bison attempts to be POSIX compatible with Yacc, it is a different
program. Since you seem to have a lexer problem, you might try the Help-Flex
list:

List-Archive: <http://lists.gnu.org/pipermail/help-flex>
List-Post: <mailto:address@hidden>
List-Help: <mailto:address@hidden>
List-Subscribe: <http://lists.gnu.org/mailman/listinfo/help-flex>,
    <mailto:address@hidden>

But Flex is a different program than Lex, and your info about your problem
is very sparse, so you may not get any replies there. You may though try
patterns as
  [_[:alpha:]][_[:alnum:]]*
