libpcap&tcpdump编译错误处理

编译错误1：找不到dbus/dbus.h，安装dbus，再执行 ln -sf /usr/local/include/dbus-1.0/dbus /usr/include/dbus

自动安装 yum install dbus
手动安装dbus，网页下载http://dbus.freedesktop.org/releases/dbus/
./configure
make 
make install

编译错误2：缺少expat，执行 yum install expat expat-devel
编译错误3：找不到dbus/dbus-arch-deps.h，执行 cp /usr/local/lib/dbus-1.0/include/dbus/dbus-arch-deps.h /usr/local/include/dbus-1.0/dbus/
编译错误4：找不到openssl/crypto.h，执行 yum install openssl openssl-devel，crypto 基于openssl，决定安装openssl-devel

安装过程中，常使用locate命令查找文件 sudo updatedb sudo locate dbus.h
