Debian环境下的Jpcap 安装与配置

环境：Debian3.2.60-1+deb7u1 x86_64 GNU/Linux

工具包：

　　　　jdk-6u45-linux-x64.bin

　　　　libpcap-1.6.1.tar.gz  (下载地址：http://www.tcpdump.org/#latest-release)

　　　　jpcap-0.7.tar.gz

安装过程：

1.      安装JDK (此处安装的为JDK1.6),并配置环境。

2.      安装下面软件之前，最好升级更新一下，以免有缺失软件包的错误

　　　　$ apt-get update

前提软件包括：gcc、flex、make 、bison

逐个检测是否存在，不存在则安装

　　　　$apt-get install gcc

　　　　$ apt-get install flex

　　　　$ apt-get install make

　　　　$ apt-get install bison

3.      将libpcap-1.6.1.tar.gz解压后复制到/usr/lib/jvm/下[具体目录按各系统情况自定]

　　$tar zxvf libpcap-1.6.1.tar.gz

　　$tar libpcap-1.6.1 /usr/lib/jvm/

然后进入该目录下：/usr/lib/jvm/libpcap-1.6.1

运行命令：

　　　　　　$./configure  –回车

　　　　　　$make  –回车

　　　　　　$make install –回车

[注意]：将/usr/local/lib下的libpcap.so.1

复制到/usr/lib/jvm/j2sdk1.6oracle/jre/lib/amd64/下，

否则最后编译文件后，运行会提醒找不到libpcap.so.1，(编译后进行链接亦可)

　　$cp libpcap.so.1 /usr/lib/jvm/j2sdk1.6oracle/jre/lib/amd64/

4.      将jpcap-0.7.tar.gz解压后复制到/usr/lib/jvm/下[具体目录视安装情况而定]

　　$tar zxvf jpcap-0.7.tar.gz

　　$cp jpcap-0.7 /usr/lib/jvm/

然后进入到jpcap安装目录src/c中，打开Makefile文件找到:

　　$(CC) $(COMPILE_OPTION) -I$(JNI_INCLUDE) 这一行修改为

　　$(CC) $(COMPILE_OPTION) -fPIC -I$(JNI_INCLUDE)  并保存

然后在src/c目录中输入命令

　　$ make –回车

这时会在src/c目录生成libjpcap.so文件,

注：如果libjpcap.so文件没有生成的话，请检查以上所提软件包有没有全部安装。

最后把生成的libjpcap.so,复制到你java目录/jre/lib/amd64下。

并将jpcap解压目录/lib下的jpcap.jar，复制到你java目录/jre/lib/ext。

　　　　$cp libpcap.so /usr/lib/jvm/j2sdk1.6oracle/jre/lib/amd64/

　　　　$cp jpcap.jar   /usr/lib/jvm/j2sdk1.6oracle/jre/lib/ext

最后附上Shell Script文件,可以一键安装Jpcap和JDK,
