[질문] "jiffies" 값을 사용하고 싶은데 컴파일조차 안되네요..
글쓴이: gihoon81 / 작성시간: 화, 2009/05/26 - 11:35오전
안녕하세요!
Function Call 을 추적하기 위해서 logging을 하는데 해당 시점에 Timestamp logging을 하려고 하고 있습니다.
기존에 Gettimeofday 를 사용하는데, 너무 많이 불려서 인지 시스템이 엄청 느려지는 현상이 발생해서 조금 더 "빠른" 놈으로 고민중에 있다가 10ms 단위로 해상력을 낮추고 "jiffies" 값을 사용하려고 테스트를 해보고 있는데 컴파일조차 되지 않아서 난감한 상황입니다.
ARM9 코어용으로 Corss-compile을 Scratchbox 에서 수행하고 있습니다.
테스트코드
#include <linux/jiffies.h>
#include <stdio.h>
int main()
{
printf("rdtdc = %ld",jiffies);
return 0;
}말도 안되는 결과.
