centos 解决/usr/bin/ld: cannot find -lfl 问题。

安装glimpse-4.18.6出现下面问题：

gcc  -o htuml2txt lex.yy.o -lfl

/usr/bin/ld: cannot find -lfl
collect2: ld returned 1 exit status

make[1]: *** [htuml2txt] Error 1

其中flex 语法解析已安装，

$ sudo yum install flex

Setting up Install Process

Nothing to do

再安装以下包支持make

 sudo yum install flex-devel  

sudo make
