error with flex

I had solved this problem like this

At the beginning of the .l file (flex file)

%option noyywrap

My entire lex file is:

%option noyywrap
number    [0-9]+\.?|[0-9]*\.[0-9]+
%%
[ ]       { /* skip blanks */ }
{number}  { sscanf(yytext, "%lf", &yylval);
            return NUMBER; }
\n|.      { return yytext[0]; }

Today I have used flex to generate lexer so I got c code and I have compiled 
it with Borland c++ compiler it notified my error like I have attatched a 
picture to you. It look like

"Unresolved external "_yywrap""

then I try to compile it again with Microsoft Visual c++ 6 and I got same 
result as before.I think I don't write this c code by my self but it 
generated from flex  a code should correct my code doesn't has this 
Identifier and I search this string in to c code generated from flex I don't 
found it too.

I think may I have done something wrong but I don't know what?  Can you give 
me some advices?
Now I am hurry because this is my homework and I have to finish it this 
week.
