開原始碼的編譯configure的相關選項

目標：移植tcpdump的檔案，apt-get source tcpdump  得到原始碼，配置  ./configure  --prefix=/home/apple/you/net/day01/test/bin_tcpdump/

缺少庫檔案：libpcap，apt-get source libpcap    得到庫的源碼，

2131  ./configure --prefix=/home/apple/you/net/day01/test/bin_libpcap/
 2132  make
 2133  make install 

到

./configure  --prefix=/home/apple/you/net/day01/test/bin_tcpdump/  --includedir=/home/apple/you/net/day01/test/bin_libpcap/include/  --libdir=/home/apple/you/net/day01/test/bin_libpcap/lib/

make
