RE: Bison 1.30

[Puttkammer, Roman]

You'll need to include some header files to avoid the errors. Use
<stdlib.h> for free(). I'm not sure where yyerror() is supposed
to be declared - I'd think it's in a header file which comes with
bison.

RE: Bison 1.30

[Stephano Mariani]

The *only* solution is:

Add
#include <stdio.h>
#include <stdlib.h>
Into the 
%{
%} Section


And add
void yyerror(char*s)
{
  printf("%s",s);
}

After the final %%

Then see if you get the same.
If so send me a copy of the output from the compiler and bison.

Stephano

PS: bison is not a compiler. In your case g++ is. Bison Is a parser
generator.

Thanks Stephano!

I wondered about versions of Bison simply to rule out possible sources
of error.  You are right in that using Bison 1.30 did not make any
difference.  

I'll try this solution next.  Thanks again!

RE: Bison 1.30

[Stephano Mariani]

You need to define your own yyerror function. Bison uses it the report
an error.
It has the following prototype: void yyerror(char*s)
As for the rest, include <stdlib.h> and/or <stdio.h>, and perhaps some
others depending on the actions you used in your rules.
I have used bison 1.28, a LOT, and found no real problems other than
suboptimal code in some cases.

Stphano Mariani

PS: You can try bison-1.30-1 now, and see for yourself bison is not at
fault.

Hi,

Because the compiler (bison 1.28) appears to be working incorrectly, I
believe that a newer version of bison might solve the problem.  I don't
know why the "implicit declaration" error is occurring.  I don't know
what to do to solve it.  The arithmetic.lex and arithmetic.y files were
compiling properly before. 
When the other files started outputting the "implicit declaration"
error, it seems that everything stopped working correctly.  The error is
of the type "implicit declaration" of several different yy functions.
If you think of something to help, please let me know.  Thanks.

Examples of the error:  
Errors of this nature cause me to believe that the compiler is failing.

C:\cygwin2\c15>g++ -Wall -c -gstabs ch1-05.y.tab.c
/usr/share/bison.simple: In function `int yyparse()':

What evidence do you have that bison would make a sudden change from its
traditional form?  If it hasn't adapted to the C89 style in over 10 years,
why now?  You ask gcc for warning messages, gcc complies.  What chance would
the cygwin developers have of changing bison, even if they wished to do so?

Re: Bison 1.30

[Randall R Schulz]

Hi,

Do you specifically need version 1.30? My Cygwin installation, which I 
belive to be complete and up-to-date, includes bison 1.28:

% bison --version
GNU Bison version 1.28


The current Cygwin also includes flex 2.5.4.

Hi Everyone, 

Happy Holidays to everyone on the list!  :)  

When you do get back, could you please tell me how to get bison 1.30 for Cygwin
to work.  Is it easy or hard to do?  What is involved in doing this?  

Is Bison 1.30 compatible with Cygwin?  Can I download the GNU source for Bison
1.30, compile it, and then use it with Cygwin?  

Thank you for your help.  :)
