Comparing to your earlier compile statement, you dropped '-lfl' which caused
the linking error. To remedy the situation add to the top of the flex file
%option noyywrap
%option noinput nounput
Then the errors should go away. The first option makes linking against the flex
library obsolete.
Enjoy flex.
