User Notes: http://wiki.linuxfromscratch.org/blfs/wiki/libpcap

Installation of Libpcap

Install libpcap by running the following commands:

./configure --prefix=/usr &&
make

　./configure

　　在这一步可能会遇到缺少flex包的问题：

configure: error: Your operating system 's lex is insufficient to compile libpcap.  flex is a lex replacement that has many advantages, including being able to compile libpcap.  For more information, see http: //www.gnu.org/software/flex/flex.html .

　　解决方法：

sudo apt-get install flex

　　

4、编译

　　make

    可能会遇到yacc错误：

yacc -d ./parse.ymake: yacc: Command not foundmake: *** [parse.c] Error 127

　　解决方法：

　

sudo apt-get install -y byacc

5、安装

　　sudo make install

 　　注意：要加上sudo，不然会出现权限问题。

6、示例

　　testlibpcap.c文件，目的是为了查询网络设备。

#include
#include
#include
#include
#include
#include
#include

int  main( int  argc, char  *argv[])
{
    char  *dev;
    char  *net;
    char  *mask;
    int  ret;
    char  errbuf[PCAP_ERRBUF_SIZE];
    bpf_u_int32 netp;
    bpf_u_int32 maskp;
    struct  in_addr addr;
    dev = pcap_lookupdev(errbuf);
    if (dev ==NULL)
    {
        printf ( "%s\n" ,errbuf);
        exit (1);
    }
    printf ( "设备名：%s\n" ,dev);
    return  0;
}

　　然后编译：

gcc  testlibpcap.c -lpcap -o testlibpcap

    gcc编译后，运行./testlibpcap会出错：

: error while  loading shared libraries: libpcap.so.1: cannot open shared object file: No such file or directory

    解决方法：

     到/usr/lib下找到libpcap.so.1.x.x文件，复制一个备份，重命名为libpcap.so.1，将libpcap.so.1后拷贝文件到/usr/lib目录下，就可以了。

 还有一点需要注意：

　　如果直接这样运行./testlibpcap，结果肯定是“no suitable device found”，原因是权限不够，所以，还需要这样运行才能结果正常。

　　sudo  ./testlibpcap

安装libjpcap：

https://code.google.com/p/jdrcom/downloads/detail?name=jpcap-0.7.tar.gz&can=2&q=

makefile 添加-fPIC

$(CC) $(COMPILE_OPTION) -fPIC -I$(JNI_INCLUDE) -I$(JNI_INCLUDE2)\ 
                 -I$(PCAP_INCLUDE)\ 

这里可能遇到jni.h头文件找不到。

通过locate jni.h查找该头问价你的目录

注意下下jdk的目录：

　

$(CC) $(COMPILE_OPTION) -fPIC -I$(JNI_INCLUDE) -I$(JNI_INCLUDE2)\ 
                 -I$(PCAP_INCLUDE)\
