Hi! With no parser.c. Main() is in the .y file, the following error occured:
alfa.tab.cpp: In function `int yyparse()': alfa.tab.cpp:1097: error: `yylex' undeclared (first use this function) alfa.tab.cpp:1097: error: (Each undeclared identifier is reported only once for each function it appears in.) alfa.tab.cpp:1315: error: `yyerror' undeclared (first use this function) alfa.ypp: In function `int yyerror(char*)': alfa.ypp:323: error: `int yyerror(char*)' used prior to declaration alfa.ypp:328: error: `vrml_filel_linenum' undeclared (first use this function -------------------------- %% int yyerror(char * s) { extern char yytext[]; int linenum; char * ff; linenum = vrml_filel_linenum(&ff); fprintf(stderr, "%s:%d: Error:\n%s before '%s'\n\n\n", ff, linenum, (char *)s, *yytext=='\n'? "\\n": yytext); return 0; } int main() { return 0; } ----------------------- What should i modify to get it work? > Hi! > > I also have a parser.c file.
