En-tête y.tab.h introuvable lors de la compilation de lex.yy.c

Question

J'essaie de créer un compilateur de base et je suis confronté à des problèmes.

Mon code flex:

    #include <stdio.h> 
    #include "SymbolTable.h" 
    #include <y.tab.h> 

    //extern "C" 
    //{ 
    // extern int yylex(void); 
    // extern int yyparse(void); 
    //} 

    int line_count = 1; 
    SymbolTable table; 
    static int yywrap(void); 

    void insert(const char* token, char* yytext) { 
    ////printf ("%s: %s ", token, yytext); 
    //printf ("%s ", token); 
    SymbolInfo symbolInfo(yytext, token); 
    table.insert(symbolInfo, line_count); 
    }

Je peux heureusement créer lex.yy.c par lex -o lex.yy.c lex.l.

Mais lorsque je tente de créer un fichier d'objets en utilisant lex g++ -c -w -o lexer.o lex.yy.c il dit

lex.l:4:19: fatal error: y.tab.h: No such file or directory 

Je l'ai déjà analysé l'analyseur en utilisant bison -d -y grammar.y

Answer 1

Modification « y.tab.h » dans votre code. En outre, vous pouvez inclure un paramètre à gcc pour inclure le chemin d'accès au fichier

g++ -c -w -I /path/to/header -o lexer.o lex.yy.c
