Ubuntu Linux C ++错误：未定义引用“clock_gettime”和“clock_settime” [英] Ubuntu Linux C++ error: undefined reference to 'clock_gettime' and 'clock_settime'

问题描述

我是Ubuntu的新手，但我似乎不能让这个工作。它在我的学校计算机上工作正常，我不知道我不在做什么。我已经检查了 usr / include 和time.h是否正好。这里是代码：

I am pretty new to Ubuntu, but I can't seem to get this to work. It works fine on my school computers and I don't know what I am not doing. I have checked usr/include and time.h is there just fine. Here is the code:

#include <iostream>
#include <time.h>
using namespace std;

int main()
{
    timespec time1, time2;
    int temp;
    clock_gettime(CLOCK_PROCESS_CPUTIME_ID, &time1);
    //do stuff here
    clock_gettime(CLOCK_PROCESS_CPUTIME_ID, &time2);
    return 0;
}

我使用CodeBlocks作为我的IDE来构建和运行。

I am using CodeBlocks as my IDE to build and run as well. Any help would be great, thank you.

推荐答案

添加 -lrt 到g ++命令行的结尾。这链接在librt.so实时共享库。

Add -lrt to the end of g++ command line. This links in the librt.so "Real Time" shared library.
