--- Comment #3 from derrick at ca dot ibm.com ---
"I assume you're compiling as C++11?"
- Oh, yes, with -std=c++11 flag:
$g++ -std=c++11 ./_222d00_s.cpp -o test
"This is not valid C++11 code, there is no implicit conversion from streams to
void* or bool in C++11."
- But after I add static_cast<bool>, it still has the error. It looks like
"loc" has some problem. If you think the code is invalid under C++11, could you
point out how I could modify the code to make it pass. Thanks.
#include <iostream>
#include <locale>
inline int operator<<(void*, const std::locale&) { return 1; }
inline int operator>>(void*, const std::locale&) { return 1; }
inline int operator<<(bool, const std::locale&) { return 2; }
inline int operator>>(bool, const std::locale&) { return 2; }
int main(int argc, char *argv[])
{
std::locale loc;
if(static_cast<bool>(std::cin >> loc)!=1)
return 1;
if(static_cast<bool>(std::cout << loc)!=1);
return 1;
return 0;
}
error: no match for 'operator>>' (operand types are 'std::istream {aka
std::basic_istream<char>}' and 'std::locale')
if(static_cast<bool>(std::cin >> loc)!=1)
error: cannot bind 'std::istream {aka std::basic_istream<char>}' lvalue to
'std::basic_istream<char>&&'
if(static_cast<bool>(std::cin >> loc)!=1)
