multithreading - CodeBlocks c++ - Can't use Thread because the compiler doesn't support it -


firstly wanted create program count time user input time zero, code - 

#include <iostream> #include <stdio.h> #include <time.h> #include <unistd.h> #include <dos.h> #include <windows.h> #include <thread> using namespace std;  //  sleep(5000); int runtimer = 1; int seconds; int hoursleft; int minutesleft; int secondscount=0; void timeleft () {     hoursleft = seconds/3600;     minutesleft = seconds/60 - hoursleft*60; } void timer () {     while(runtimer=1)     {          if (secondscount == 60)     {     timeleft();     cout << "the amount of time left is: " << hoursleft << " hours , " << minutesleft << " minutes left." << endl;     secondscount=0;     }     secondscount++;     seconds--;     sleep(1000);     timer();     }  } int main() {     // introduction , time picking     cout << "welcome timer - please set amount of hours , minutes want timer run" << endl;     double requestedhours, requestedminutes;     cin >> requestedhours;     cin >> requestedminutes;     double requestedseconds = requestedhours*3600 + requestedminutes*60;     seconds = requestedseconds;     cout << "timer started";     timer(); }

but wanted add function in user type word or letter pause program, (and after bit of reearching found out threading) - when added #include <thread> got massage - 

"#error file requires compiler , library support \ iso c++ 2011 standard. support experimental, , must \ enabled -std=c++11 or -std=gnu++11 compiler options. #endif"

how fix this?

you seem using g++ in windows assume flavour of mingw came code::blocks.

gnu glibc doesn't support windows threads (its dev team doesn't care windows) have either use mingw pthread build, or use add-on.

firstly should add -std=c++11 build options.

however, error message suggests have installed quite old version of g++ recommend upgrading mingw-w64 (an actively-maintained fork of mingw). see here installation help.

for more info thread support in various versions of mingw see this thread. use mingw-w64 win32 threads , meganz addon in code::blocks successfully.
