Thread: ' Mutex ' in namespace ' std ' does not name a type | ??

Good all day! Error-D:\Classes\mutex1\mutex1.cpp | 9 | error: ' mutex ' in namespace ' std ' does not name a type |

That is, write please!? In fact, this should not and cannot be?

Code:

#include <iostream>
#include <chrono>
#include <thread>
#include <mutex>
#include <map>
#include <string>
 
std::map<std::string, std::string> g_pages;
std::mutex g_pages_mutex;

Thank you so much! But no, the mutex is spelled with a small letter. It looks like it's probably different mutex and Mutex.
Anyway, I'm reading about everywhere mutex, see written with examples. And I can't compile fails to collect samples.
Here's an example here mutex - C++ Reference and here std::mutex — cppreference.com for example yet.

I first just wanted to compile this code

Code:

#include <mutex>

void foo()
{
    std::mutex m;
}


#include <iostream>
#include <cstdlib>

#include <timertt/all.hpp>

using namespace std;
using namespace std::chrono;
using namespace timertt;

int main()
{
   timer_wheel_thread_t tt;

   // Timer thread must be started before activation of timers.
   // Таймерний потік повинен запускатися перед активацією таймерів.
   tt.start();

   // The simple single-shot timer.
   // простий одноразовий таймер.
   tt.activate( milliseconds( 20 ),
         []() { cout << "Simple one-shot" << endl; } );

   // The simple periodic timer.
   // Will work until timer thread finished.
   // простий періодичний таймер.
      // Буде працювати, поки закінчиться таймер.
   tt.activate( milliseconds( 20 ), milliseconds( 20 ),
         []() {
            static int i = 0;
            cout << "Simple periodic (" << i << ")" << endl;
            ++i;
         } );

   // Allocation of timer and explicit activation.
   //  озподіл таймера та явної активації.
   auto id1 = tt.allocate();
   tt.activate( id1, milliseconds( 30 ),
         []() {
            cout << "Preallocated single-shot timer" << endl;
         } );

   // Periodic timer with timer preallocation, explicit activation
   // and deactivation from the timer action.
   // Періодичний таймер з попереднім розподілом таймера, явна активація
      // і деактивація з дії таймера.
   auto id2 = tt.allocate();
   tt.activate( id2, milliseconds( 40 ), milliseconds( 15 ),
         [id2, &tt]() {
            static int i = 0;
            cout << "Preallicated periodic (" << i << ")" << endl;
            ++i;
            if( i > 2 )
               tt.deactivate( id2 );
         } );

   // Single-shot timer with explicit activation and deactivation
   // before timer event.
   // одноразовий таймер з явною активацією та деактивізацією
      // перед таймером
   auto id3 = tt.allocate();
   tt.activate( id3, milliseconds( 50 ),
         []() {
            cerr << "This timer must not be called!" << endl;
            std::abort();
         } );
   tt.deactivate( id3 );

   // Wait for some time.
   // Зачекайте деякий час.
   this_thread::sleep_for( milliseconds( 200 ) );

   // Finish the timer thread.
   // Завершити потік таймера.
   tt.shutdown_and_join();
}

and got the same error in one of the plug-in files.

Can I still need some heders connect to compile properly, all settings of the compiler seems in order ...

In General, what to do?

All, it's all std: mutex gives an error. That's interesting!

I compiling as C++0x

maybe your C++ compiler hasn't implemented std::mutex
Yes, I guess it's something like that.

Tell me please, and I can download new inkludy needed on drive d, without affecting the c drive which is full?
How best to instruct the compiler to new inkludy?
I have an old computer with 32 bits.

Where better to download?

D:\codeblocks-16.01mingw-nosetup\mingw\include will fit me?

You need to understand that Code::Blocks is an Editor/IDE and it is not an Compiler!!

You need to learn about your Compiler! It might have a setting to change to C++11 support.
