I try to run the example on http://tldp.org/HOWTO/Lex-YACC-HOWTO-4.html. But I get the following error. Could somebody let me know what I am wrong?
$ bison -d example4.y example4.y:24.1-8: syntax error, unexpected identifier: $ cat example4.y %{ #include <stdio.h> #include <string.h> void yyerror(const char *str) { fprintf(stderr,"error: %s\n",str); } int yywrap() { return 1; } main() { yyparse(); } %} %token NUMBER TOKHEAT STATE TOKTARGET TOKTEMPERATURE commands: /* empty */ | commands command ; command: heat_switch | target_set ; heat_switch: TOKHEAT STATE { printf("\tHeat turned on or off\n"); } ; target_set: TOKTARGET TOKTEMPERATURE NUMBER { printf("\tTemperature set\n"); } ; _______________________________________________ help-bison@gnu.org http://lists.gnu.org/mailman/listinfo/help-bison
