你好，我有一个关于libpcap的问题 [英] hello i have a question about libpcap SOLVED

问题描述

您好，我想安装libpcap并遵循以下方法:
./configure
制作
进行安装

我已经用一个程序对其进行了测试，那么代码是:

hello, I want to install the libpcap and follow this ways:
./configure
make
make install

and I have used a program to test it, then the code is:

#include <stdio.h>
#include <stdlib.h>
#include <pcap.h>

int main( int argc, char** argv )
{
        char *dev, errbuf[PCAP_ERRBUF_SIZE];
        dev = pcap_lookupdev( errbuf );
        if ( dev == NULL )
        {
                fprintf( stderr, "couldn't find default device: %s\n", errbuf );
                return ( 2 );
        }
        printf( "Device: %s\n", dev );
        return ( 0 );
}

当我用gcc编译时，"gcc -o test24 -g test24.c -lpcap"
它将显示错误:

when I compile it by gcc, "gcc -o test24 -g test24.c -lpcap"
it will print the error :

/usr/local/lib/libpcap.so: undefined reference to `pcap_parse'
collect2: ld returned 1 exit status

请告诉我为什么?谢谢
