Eclipse無法識別下面代碼中的「CLOCK_PROCESS_CPUTIME_ID」。操作系統是Ubuntu，我正在使用英特爾編譯器。代碼執行，但突出顯示語法錯誤。在代碼下方顯示了我的構建「腳本」。有人可以幫我解決語法突出問題嗎？在Eclipse中未識別Linux CLOCK_PROCESS_CPUTIME_ID CDT
#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;
}
這是我的構建腳本：

在哪裏定義了CLOCK_PROCESS_CPUTIME_ID？ – Massa
@Massa我只是Linux的初學者，但我相信它是用於本機C/C++函數的某種OS結構？正如我所說的，代碼執行：s – user997112
好吧，嘗試'#include'而不是'time.h';也許你的eclipse安裝有一些問題。我會在今天晚些時候嘗試。 –
