【问题描述】：

Eclipse 无法识别以下代码中的“CLOCK_PROCESS_CPUTIME_ID”。操作系统是 Ubuntu，我使用的是英特尔编译器。代码执行，但语法错误突出显示。在代码下方，我展示了我的构建“脚本”。有人可以帮我解决语法高亮问题吗？

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

timespec diff(timespec start, timespec end);

int main()

    timespec time1, time2;
    char b = 'A';
    bool result;

    clock_gettime(CLOCK_PROCESS_CPUTIME_ID, &time1);  //Eclipse highlights as error
    result = (b < 58 & b > 47);
    clock_gettime(CLOCK_PROCESS_CPUTIME_ID, &time2);  //Eclipse highlights as error
    cout<<diff(time1,time2).tv_sec<<":"<<diff(time1,time2).tv_nsec<<endl;
    cout << result << endl;
    return 0;


timespec diff(timespec start, timespec end)

    timespec temp;
    if ((end.tv_nsec-start.tv_nsec)<0) 
        temp.tv_sec = end.tv_sec-start.tv_sec-1;
        temp.tv_nsec = 1000000000+end.tv_nsec-start.tv_nsec;
     else 
        temp.tv_sec = end.tv_sec-start.tv_sec;
        temp.tv_nsec = end.tv_nsec-start.tv_nsec;
    
    return temp;

这是我的构建脚本：

【问题讨论】：

CLOCK_PROCESS_CPUTIME_ID 定义在哪里？

@Massa 我只是 Linux 的初学者，但我相信它是用于原生 C/C++ 函数的某种操作系统结构？正如我所说，代码执行：s

好吧，试试#include <ctime> 而不是time.h；也许你的eclipse安装有问题。今天晚些时候我会试试的。

@Massa 仍然不起作用。如果您以后可以尝试，将不胜感激:)

我安装了 Eclipse（JunoCDT，通过 Pulse），创建了一个新项目，但这里没有显示错误……抱歉，我帮不上忙。

【参考方案1】：

好的，要解决这个问题，我必须进入我的项目设置“索引器”，并且有一个您“预先”索引的头文件列表。我在此列表中添加了“time.h”，然后重新构建了项目。

完全不知道为什么需要这样做？！
