Subject: problems linking with -lfl option
Package: flex-old
Version: 2.5.4a-7
Severity: normal
I have the following file:
%option noyywrap
%{
int voc,con;
%}
%%
a|e|i|o|u voc++;
[a-z] con++;
. ;
%%
int main(){
yylex();
printf("voc: %3d con: %3d\n",voc,con);
}
just a simple example... if I do
flex file.l; gcc lex.yy.c
everything is ok, but if i remove the
%option noyywrap
directive, and do
flex file.l; gcc -lfl lex.yy.c
I get these errors:
/tmp/ccgksxij.o: In function `main':
lex.yy.c:(.text+0xfdd): multiple definition of `main'
/usr/lib/gcc/i486-linux-gnu/4.1.2/../../../../lib/libfl.a(libmain.o):/home/srivasta/flex-old-2.5.4a/libmain.c:10:

/tmp/ccgksxij.o: In function `input':

collect2: ld returned 1 exit status
I have the same problem with flex package.
