我遇到这个问题是因为头文件的引用不当。具体原因我现在也不懂，但是我把头文件的引用顺序调整了一下就没问题了。

下面是我的头文件引用的具体情况：

①编译有问题的引用：

#include<string>#include <iostream>#include<fcntl.h>#include <sys/socket.h>#include <sys/types.h>#include <stdlib.h>#include <sys/un.h>#include <pthread.h>#include <arpa/inet.h>#include "apue.h"//这里以下3个头文件改动顺序。#include "get_set_time.cpp"#include "node.cpp"#include "DevConfig/GetSetIpDns.cpp"#include "BroadCast/BroadCastReceiver.cpp"#include "DevConfig/DevConfig.cpp"#include "UniCast/UniCastReceiver.cpp"#include "UniCast/UniCastSender.cpp"

②修改后编译没问题：

#include<string>#include <iostream>#include<fcntl.h>#include <sys/socket.h>#include <sys/types.h>#include <stdlib.h>#include <sys/un.h>#include <pthread.h>#include <arpa/inet.h>#include "DevConfig/GetSetIpDns.cpp"#include "BroadCast/BroadCastReceiver.cpp"#include "DevConfig/DevConfig.cpp"#include "UniCast/UniCastReceiver.cpp"#include "UniCast/UniCastSender.cpp"#include "apue.h"//3个头文件的引用放到最后。#include "get_set_time.cpp"#include "node.cpp"
