问题:libpcap编译问题?

kdhmstd

libpcap 下载后，
   执行./configure
          出现 error: Your operating system's lex is insufficient to compile
libpcap.  flex is a lex replacement that has many advantages, including
being able to compile libpcap.  For more information, see
http://www.gnu.org/software/flex/flex.html .

smqt
