Hi,
I am trying to add line numbers to my parser's error messages. I have
included the options, %locations and %define api.pure in my bison
definition file, but it seems to be generating yyerror with this signature:
yyerror(const char *msg);
instead of the signature I am expecting:
yyerror (YYLTY

If, at least for a start until you know the other things work, you use
an array that can hol

The input I have is linear equation like:
2 * x + ( x - y ) = x + 1
And I would like to get at end
2 * x - y = 1
I studied the calculator example, and be able to build ast tree.
however I have no way to reduce it. Please give me an example or
