Yes, you need a rule to make lex.yy.c in the makefile. If you manually type:
before invoking make, that kind of defeats the purpose of using make, doesn't it?
If you invoke make without specifying a target operand on the command line, how does make decide what target(s) need(s) to be built?

Makefile::AST(3pm) User Contributed Perl Documentation Makefile::AST(3pm)NAME
Makefile::AST - AST for (GNU) makefiles
DESCRIPTION
The structure of this (GNU) makefile AST is designed based on GNU make's data base listing output produced by "--print-data-base".
This AST library provides the following classes:
Makefile::AST
The primary class for ASTs. Provides interface for node adding and querying, such as "add_implicit_rule", "apply_implicit_rules",
"add_explicit_rule", "apply_explicit_rules", "add_var", "add_auto_var", "get_var", as well as lots of other utility functions, like
method "eval_var_value" for computing the ultimate values of makefile variables, method "enter_pad" and "leave_pad" for local
variable's scoping pad.
Makefile::AST::Rule::Base
This is the base class for the rule nodes in the AST. It has properties like "normal_prereqs", "order_prereqs", "commands", and
"colon".
Makefile::AST::Rule
This class represents the de-sugared form of simple rules and implicite rules after application. It inherits from
Makefile::AST::Rule::Base, and adds new properties "target" and "other_targets".
Makefile::AST::Rule::Implicit
This class represents the implicit rule nodes in the AST. It inherits from Makefile::AST::Rule::Base, and adds new properties
"targets", "match_anything", and "is_terminal".
Makefile::AST::StemMatch
This class encapsulates the file pattern matching (file names containing "%") and stem substitution algorithms.
Makefile::AST::Variable
It represents the makefile variable nodes in the AST, including "name", "value", "flavor", and "origin".
Makefile::AST::Command
Used to encapsulate information regarding makefile rule commands (e.g. command body, command modifiers "@", "-", "+", and etc.) as a
whole.
LIMITATIONS AND TODO
Adding support for other flavors' makes into this AST library should make a huge amount of sense. The most interesting candiate is
Microsoft's NMAKE.
