What is your database version ? It seems that it is not an enterprise edition so DWH (OLAP) there will not work.
Your code works, I have tested it.

If you use stored procedure you can do something like this:

create or replace procedure my_proc (d_start  DATE,d_end    DATE) is
--  d_start  DATE:=to_date('18.10.2007','dd.mm.yyyy');
--  d_end    DATE:=to_date('17.11.2007','dd.mm.yyyy');
  d_value  DATE;
begin
d_value:=d_start;
while d_value<=d_end
loop
dbms_output.put_line(to_char(d_value,'dd.mm.yyyy'));
d_value:=d_value+1;
end loop;
end;

For dates from 10-18-2007 to 11-17-2008,
select trunc(to_date('Oct-18-2007','Mon-DD-YYYY')) - 1 + level
from dual
connect by level <= trunc(to_date('Nov-17-2008','Mon-DD-YYYY')) - trunc(to_date('Oct-18-2007','Mon-DD-YYYY')) + 1;
