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. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] On Behalf Of Fractal A.

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.
