output operator<< of thread::id

[ka55i0peia@…]

Hi,

std::cout << boost::this_thread::get_id();

produces:

thread.hpp(473) : error C2662: 'std::basic_ostream<_Elem,_Traits> &boost::thread::id::print<char,std::char_traits<char>>(std::basic_ostream<_Elem,_Traits> &)' : cannot convert 'this' pointer from 'const boost::thread::id' to 'boost::thread::id &'

For me it was okay to comment the const out:

operator<<(std::basic_ostream<charT, traits>& os, /*const*/ thread::id& x)
    {
        return x.print(os);
    }

Greetings, Jan.

I suspect that the actual problem is that thread::id::print is not const, and the fix is to add that, rather than removing the const on operator <<
