クロノでのコンパイルに問題があります。コードは次のとおりです。
時間.hh
#include <chrono>
class Time
{
protected:
std::chrono::steady_clock::time_point _start_t;
std::chrono::steady_clock::time_point _now;
std::chrono::steady_clock::time_point _time;
public:
Time();
Time(const Time &other);
Time &operator=(const Time &other);
~Time();
public:
void start();
double getDurSec();
double getDurMilSec();
private:
void setNow();
};
コンパイル エラー:
g++ -W -Wall -Wextra -I./include -std=c++0x -c -o src/Time/Time.o src/Time/Time.cpp
