问题C1083：无法打开包含文件：'chrono'：没有这样的文件或目录弹出 [英] Issue C1083: cannot open include file: 'chrono': no such file or directory pops out

问题描述

这是我的.pro档案

  QT + = core gui 
 
 greaterThan（QT_MAJOR_VERSION，4）：QT + = widgets 
 
 TARGET = Lotto 
 TEMPLATE = app 
 
 CONFIG + = c ++ 11

 mainwindow.cpp \ 
 lottogenerator.cpp 
 
 HEADERS + = mainwindow.h \ 
 lottogenerator.h 
 
 FORMS + = mainwindow.ui 
  
 
 
 
这是我的.h文件
  ifndef LOTTOGENERATOR_H 
 #define LOTTOGENERATOR_H 
 
 
 #include< string> 
 #include< random> 
 #include< array> 
 #include< chrono>

 std :: uniform_int_distribution< int>分配; 
 
 myclock :: time_point beginning = myclock :: now（）; 
}; 
 
 #endif // LOTTOGENERATOR_H 
  
这是我的.cpp文件。 / p> 
 
 
  #includelottogenerator.h
 
 LottoGenerator :: LottoGenerator（）
：distribution （1,45）

 myclock :: duration d = myclock :: now（） -  beginning; 
 unsigned int seed = d.count（）;

 numbers [4] = rand（）; 
 numbers [5] = rand（）; 
 
返回数字; 
} 
 
 int LottoGenerator :: rand（）
 {
 return distribution（engine）; 
} 
  
当我运行时，C1083：无法打开包含文件：'chrono' 
 
 
 
如果您能帮助我们，非常感谢。）
解决方案
您使用的MSVC版本太旧。错误起源于编译器，而不是在Qt Creator。
 
I'm trying to make a program that makes 6 numbers come out randomly.

This is my .pro file
QT       += core gui

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

TARGET = Lotto
TEMPLATE = app

CONFIG += c++11

SOURCES += main.cpp\
        mainwindow.cpp \
    lottogenerator.cpp

HEADERS  += mainwindow.h \
    lottogenerator.h

FORMS    += mainwindow.ui
This is my .h file
#ifndef LOTTOGENERATOR_H
#define LOTTOGENERATOR_H


#include <string>
#include <random>
#include <array>
#include <chrono>

class LottoGenerator
{
public:
    typedef std::chrono::high_resolution_clock myclock;

    LottoGenerator();

    std::array<int, 6> get();

private:
    int rand();

    std::mt19937 *engine;
    std::uniform_int_distribution<int> distribution;

    myclock::time_point beginning = myclock::now();
};

#endif // LOTTOGENERATOR_H
This is my .cpp file.
#include "lottogenerator.h"

LottoGenerator::LottoGenerator()
    : distribution(1,45)
{
    myclock::duration d = myclock::now() - beginning;
    unsigned int seed = d.count();

    engine.seed(seed);
}

std::array<int, 6> LottoGenerator::get()
{
    std::array<int, 6> numbers;

    numbers[0] = rand();
    numbers[1] = rand();
    numbers[2] = rand();
    numbers[3] = rand();
    numbers[4] = rand();
    numbers[5] = rand();

    return numbers;
}

int LottoGenerator::rand()
{
    return distribution(engine);
}
and when I run, "C1083: cannot open include file: 'chrono': no such file or directory" pops out.

It would be grateful if you could help:) 
解决方案
You are using a MSVC version that is too old. The error originates in the compiler, not in Qt Creator.
