makefile出现报错（系统时间问题）

编译安装出现的一个问题：

Makefile is unchanged.

make: Warning: File `configure.sh' has modification time 8.5e+05 s in the future

config.status: creating Makefile

config.status: creating lib/dummy

config.status: creating zlib/dummy

config.status: creating popt/dummy

config.status: creating shconfig

config.status: creating config.h

config.status: config.h is unchanged

解决：出现这样一个报错是因为系统时间比configure.sh文件的修改时间要早，我们调整一下系统时间就可以了。
