To turn back to my problem =) , Here's my method:

string GeneratorUtils::getRandomID(){

    random_generator gen;
    uuid u = gen();

    //string str = boost::lexical_cast<string>(u);
    string str = boost::lexical_cast<char*>(u);

    return str;
}

And here's my test code:

int main(){
    cout << "SAYGIN" << endl;

    GeneratorUtils gen;
    cout << gen.getRandomID() << endl;

    return 0;
}


And here's the output:
$ ~/DAIM_MPI_Correlation/utils$ g++ -c GeneratorUtils.cpp
$ g++ -o test GeneratorUtils.cpp
$ ./test
SAYGIN
terminate called after throwing an instance of 'boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<boost::bad_lexical_cast> >'
  what():  bad lexical cast: source type value could not be interpreted as target
Aborted

Do you have any idea?

Hmm, I haven't really given it much thought.  Since it doesn't need to
be a member function, I would lean toward a standalone function.  Do
any other libraries have a similar function?  I would likely create:

template <typename C, typename T, typename A>
std::basic_string<C, T, A> to_basic_string(boost::uuids::uuid const& u);

as well as,

std::string to_string(boost::uuids::uuid const& u);
std::wstring to_wstring(boost::uuids::uuid conts& u);

+1, unqualified call to to_string is how Boost Exception converts to
string arbitrary objects stored in exception objects. If you use this
form and someone adds a UUID to a boost::exception, it'll appear
correctly in the output from boost::diagnostic_information.

a to_string() member is IMO much preferred for simplicity and the encapsulation perspective. Just like std::bitset<N>::to_string().

There seem to be no standard in Boost for this :-(, e.g. filesystem uses
::string(), format uses ::str().
