Linux 错误记录：configure: error: Neither flex nor lex was found.

今天在安装nmap的时候执行  ./configure

提示错误 ：configure: error: Neither flex nor lex was found.

解决方法：

[ libpcap-1.8.1]# yum install flex bison

安装以后又提示：

fatal error: nbase_config.h: No such file or director

解决办法：

重新执行   ./configure

make install
