Arghh... really doesn't help that I had a file called makefile in my directory, which make was using instead of Makefile Smilie

Code:
populateMFiles() {
#echo '.PHONY: all clean build
echo 'clean:
        rm -rf cfile.c cfile.out
build:
        gcc -g -Wall -pedantic -Wextra cfile.c -w -o cfile.out
all: clean build'
}

This does work fine, as far as I can see, so it would help to see the actual make error, not the one your script is displaying.

Saying nothing as to the rest of your code because I haven't read it, it would be slightly cleaner using cat instead of echo to print the Makefile and C file.

e.g.
Code:
populateMFiles() {
cat << EOF
clean:
        rm -rf cfile.c cfile.out
build:
        gcc -g -Wall -pedantic -Wextra cfile.c -w -o cfile.out
all: clean build
EOF
}

Code:
$ functions
populateMFiles() {
cat << EOF
clean:
	rm -rf cfile.out
build:
	gcc -g -Wall -pedantic -Wextra cfile.c -w -o cfile.out
all: clean build
EOF
}

$ cat cfile.c
int main( void ) {
  printf( "%s", "Hello world!\n" );
  return 1;
}

$ populateMFiles > Makefile

$ cat Makefile
clean:
	rm -rf cfile.out
build:
	gcc -g -Wall -pedantic -Wextra cfile.c -w -o cfile.out
all: clean build

$ make all
rm -rf cfile.out
gcc -g -Wall -pedantic -Wextra cfile.c -w -o cfile.out

$ ls cfile.out
cfile.out

$ ./cfile.out
Hello world!

Your makefile may remove the cfile.c file, so you need to run "populateCFiles" every time before you run make (as clean is the first rule), make all or make clean.

makefile::ast

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.
