这是怎么回事呢，应该怎么解决呢？

晕倒
你就算多加个 -S
拜托用大写
你可能没有装全开发环境 如 man文档等
man 3 sleep
SLEEP(3) Linux Programmer滻 Manual SLEEP(3)
NAME
sleep - Sleep for the specified number of seconds
SYNOPSIS
#include <unistd.h>
unsigned int sleep(unsigned int seconds);
DESCRIPTION
sleep() makes the current process sleep until seconds seconds have
elapsed or a signal arrives which is not ignored.
RETURN VALUE
Zero if the requested time has elapsed, or the number of seconds left
to sleep.
CONFORMING TO
POSIX.1
BUGS
sleep() may be implemented using SIGALRM; mixing calls to alarm() and
sleep() is a bad idea.
Using longjmp() from a signal handler or modifying the handling of
SIGALRM while sleeping will cause undefined results.
SEE ALSO
signal(2), alarm(2)
