Jpcap mac 开发环境搭建

如下为官方文档叙述：

Mac OS X

Both Java and libpcap are preinstalled on Mac OS X.
If any of them is missing you should be able to install them from the Mac OS X install DVD.
Download and install Xcode.
The default installation of Xcode should provide you with the toolchain required for compiling Jpcap.
Download and extract Jpcap source build.
Go to ‘[Jpcap extracted directory]/src/c’ directory.
Run ‘make’.
Copy ‘libjpcap.jnilib’ to ‘/Library/Java/Extensions/’ directory.
Copy ‘[Jpcap extracted directory]/lib/jpcap.jar’ to ‘/Library/Java/Extensions/’
Or, place ‘jpcap.jar’ to any directory and include it to your CLASSPATH.

预装软件：
1.安装Xcode 及 install 。 否则mac OS 没有make 环境；
2.安装libjpcap

在tcpdump网站(http://www.tcpdump.org)下载libpcap的latest release.
解压之后，在软件目录下执行./configure
执行 make
执行 make install

此时，在/usr/local/lib目录下会生成libpcap的动态链接库，如：libpcap.dylib

执行export DYLD_LIBRARY_PATH=/usr/local/lib 将此目录加入动态链接库的CLASSPATH
编写测试代码测试是否可用：

下载Jpcap https://github.com/jpcap/jpcap
在[Jpcap extracted directory]/src/c 运行 make

将编译出来的 ‘libjpcap.jnilib’ 和 ‘jpcap.jar‘ copy到 ‘/Library/Java/Extensions/’目录下.
