Linux GCC编译警告:Clock skew detected. 错误解决办法

本文介绍了一种在使用GCC编译程序时遇到的“make: warning: Clock skew detected”警告问题及其解决方法。该问题源于系统时间设置不正确,通过调整系统时间为当前实际时间,可以有效避免编译过程中的时钟偏移警告。

今天在虚拟机上用GCC编译一个程序的时候,出现了下面的错误:

make: warning: Clock skew detected. Your build may be incomplete

试了make clean后再make,仍然是同样的问题,最后发现这个错误的原因在于系统时间比文件修改时间早,看了下我的系统时间竟然还是2012-01-13,而今天都已经是2012-01-31呢,于是修改时间后重新编译,问题解决。

Linux下用date命令可查询和修改系统时间(root权限才可修改)

1 date    查询系统时间
2 date -s 1/31/2012   命令可以修改系统日期
3 date -s 22:34:50    命令可以修改系统时间
