Problem:
You are trying to use the std::put_time
function in your C++ application, but you get the following compiler error message:
main.cpp:17:16: error: no member named 'put_time' in namespace 'std' ss << std::put_time(std::localtime(&localTime), "%F_%H-%M-%S") << extension; ~~~~~^
Solution:
The std::put_time
function is part of the <iomanip>
header in C++, so you need to include this header in your code to use this function. Add the following code at the top of the file where the error occurs:
#include <iomanip>
Full example:
#include <iostream> #include <iomanip> #include <chrono> int main() { auto now = std::chrono::system_clock::now(); auto localTime = std::chrono::system_clock::to_time_t(now); std::cout << std::put_time(std::localtime(&localTime), "%F %T") << std::endl; return 0; }
