I'm learning bison and flex, and I'm trying to modify the calculator example in the bison tutorial to use a flex-generated scanner. Here's the contents of my compilation buffer:
cd ~/calc/ make -k bison calc.y gcc -c calc.tab.c bison -d calc.y flex calc.lex.y gcc -c lex.yy.c In file included from calc.lex.y:2: calc.tab.h:4: parse error before `symrec' calc.tab.h:4: warning: no semicolon at end of struct or union calc.tab.h:5: warning: data definition has no type or storage class There are more errors, but you get the point. Heres the output of bison -d: $ cat calc.tab.h typedef union { double val; symrec *tptr; } YYSTYPE; #define NUM 258 #define VAR 259 #define FNCT 260 #define NEG 261 extern YYSTYPE yylval; I searched the bug list and found only unrelated bison problems. I searched the debian-user archives and found an apparently unresolved thread from July 20, 1997, entitled "Q: gcc and flex/bison ?". I searched the GNU help-bison archives and found it very annoying that the messages can not be sorted by thread.
