Hi.
I am a beginner with Flex. I am using flex-2.5.4a37.4 on fedora core 5. i
prepared a file lex.l (the contents of which are copied at the end of the
mail).
then i issued the following commands :
flex lex.l
gcc -lfl lex.yy.c
however the linker produced the error :

/tmp/ccodQ1yE.o: In function `main':lex.yy.c:(.text+0xfb3): multiple
definition of `main'
/usr/lib/gcc/i386-redhat-linux/4.1.0/../../../libfl.a(libmain.o): first
defined here
/usr/bin/ld: Warning: size of symbol `main' changed from 48 in
/usr/lib/gcc/i386-redhat-linux/4.1.0/../../../libfl.a(libmain.o) to 55 in
/tmp/ccodQ1yE.o
collect2: ld returned 1 exit status

can someone please point out my error?
sincerely,
rahul garg

the input file lex.l is :

%option nomain noyywrap
delim [ \t\n]
ws {delim}+
letter [a-zA-Z]
digit [0-9]
id {letter}({letter}|{digit})*
number {digit}+(\.{digit}+)?(E[+-]?{digit}+)?

%%

{ws} {}
if|then|else|def {printf("keyword %s\n",yytext);}
{id} {printf("identifier %s\n",yytext);}
{number} {printf("number %s\n",yytext);}

%%

int main(int argc,char** argv){
int count = 100;
while(count>0){
    yylex();
    count--;
}
return 0;
}
