ooopps, ok I forgot to include uuid_io.hpp file. Now it compiled... Thanks a lot for your helps. And about the discussions, I agree that there would be nice to have a function u.to_string() =) Saygin On Mon, May 10, 2010 at 11:04 PM, Andy Tompkins <atompkins@fastmail.fm>wrote:

Hi, I'm a newbie on boost. I've downloaded and used some features.
I couldn't find how to cast uuid into string.
#include "boost/date_time/gregorian/gregorian.hpp" #include <boost/uuid/uuid.hpp> #include <boost/uuid/uuid_generators.hpp> #include <boost/uuid/random_generator.hpp> #include <boost/uuid/string_generator.hpp>
...
date GeneratorUtils::getRandomDate() { int year, month ,day; day = rand() % 30; month = rand() % 12; year = 1980 + rand() % 25; string str_date = "" + day + month + year ; date d(from_simple_string(str_date));
return d;
string GeneratorUtils::getRandomID(){
random_generator gen; uuid u = gen();
return u.uuid_to_string(); // ERROR }
It does not accept any to_string() function. Is there a way to convert from uuid to string in C++? (by the way, I can use the other things such as date d, uuid u etc.)
see http://www.boost.org/doc/libs/1_43_0/libs/uuid/uuid.html#boost/uuid/uuid_io.... one can also use lexical_cast eg:
uuid u; string s = lexical_cast<string>(u);
I'll update the documentation to include this example.
Regards, Andy.
