<span style="font-size:18px;">#include<iostream>#include<stdio.h>#include<string.h>#include<stdlib.h>#include<sys/socket.h>#include<sys/types.h>#include<netinet/in.h>#include<event.h>struct event ev;struct timeval tv;void time_cb(int fd,short event,void *argc){        printf("timer wakeup\n");        event_add(&ev,&tv);}int  main(){        struct event_base *base =(struct event_base*)event_init();        tv.tv_sec = 10;        tv.tv_usec = 0;        evtimer_set(&ev,time_cb,NULL);        event_add(&ev,&tv);        event_base_dispatch(base);        return 0;}</span>

编译：g++ -g test.cpp -o test -levent

如果出现错误如下：

./test: error while loading shared libraries: libevent-1.2.so.1: cannot open shared object file: No such file or directory

解决方案：

先执行命令：ldconfig

然后执行：./test
