OLSR_hello& hello = msg.hello();

    link_tuple->nb_iface_addr() = sender_iface;
    link_tuple->local_iface_addr() = receiver_iface;
    //For testing only
    if(sender_iface == 168427530 && receiver_iface == 169082900 ) //Error occur at this line

OLSR头文件OLSR.h 

virtual bool        link_sensing(OLSR_msg&, const nsaddr_t &, const nsaddr_t &, const int &);

error get: Description
没有匹配'receiver_iface == 169082900'中的'operator=='

错误信息明确

没有匹配'receiver_iface == 169082900'中的'operator=='

表示编译器不理解

中的==是什么意思
receiver_iface == 169082900

也就是说，它不知道如何比较receiver_iface和169082900。

receiver_iface是nsaddr_t类型(不管它是什么)，169082900是int类型。

因此，应该在导致错误的代码之前定义以下函数: 
bool operator== (const nsaddr_t &left, int right)
{
    // whatever you consider appropriate
}
