Bug ID: 62082
Summary: cout fails to work with auto variable initialized with
curvy brackets
Product: gcc
Version: 4.9.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: aleksej.penkov at hotmail dot com
This simple code (compiled with -std=c++11 -Wall):
#include <iostream>
int main()
{
double d = 5.5;
auto a {d};
std::cout<<d<<' '<<a<<std::endl;
}
gives this compilation error:
2.cpp: In function âint main()â:
2.cpp:8:14: error: cannot bind âstd::basic_ostream<char>â lvalue to
âstd::basic_ostream<char>&&â
std::cout<<d<<' '<<a<<std::endl;
^
In file included from /usr/local/include/c++/4.9.1/iostream:39:0,
from 2.cpp:1:
/usr/local/include/c++/4.9.1/ostream:602:5: note: initializing argument 1 of
âstd::basic_ostream<_CharT, _Traits>&
std::operator<<(std::basic_ostream<_CharT, _Traits>&&, const _Tp&) [with _CharT
= char; _Traits = std::char_traits<char>; _Tp = std::initializer_list<double>]â
operator<<(basic_ostream<_CharT, _Traits>&& __os, const _Tp& __x)
^
If i replace
auto a {d};
with
auto a = d;
it works fine.
