Homework & Coursework Questions

Use and complete the template provided. The entire template must be completed. If you don't, your post may be deleted!

1. The problem statement, all variables and given/known data:

Basically, the prompt is make a makefile with various sub makefiles in their respective subdirectories. All code provided compiles and do not need to be checked so I won't put them here. I'm just having trouble with the makefiles themselves.

=====

The directory tree you will be working with has the following root:

makefile_assignment/: <== You are here.

The directory "makefile_assignment/" contains the following four
subdirectories:

bin/ c/ cpp/ java/

Except for "makefile_assignment/bin/", each subdirectory above
represents a subtask. Be aware that there are further subtasks in
"C and SPARC assembly subtask" and "C++ and archiving subtask"! These subtasks
will be described before the rest of "Makefile task", because "Makefile task"
depends on all of them as subtasks.

=====
BEGIN: C subtask
=====

The directory "makefile_assignment/c/" contains a C header file, "functions.h",
and a single C file, "main.c", in addition to one subdirectory:

cfiles/

=====
BEGIN: C dependencies subtask
=====

The directory "makefile_assignment/c/cfiles/" contains the following C source
files:

factorial.c fibonacci.c hanoi.c print_string.c sum_4_nums.c summation.c

For this subtask ("C subtask"), you must write a Makefile to do the following:

default target:

1. Compile all source files into object code files.

2. Copy all object code files into the parent directory.

clean target:

1. Delete all object code files.

2. Delete all core dumps.

new target:

1. "make" the "clean" target.

2. "make" the "default" target.

=====
END: C dependencies subtask
=====

For this subtask ("C subtask"), you must write a Makefile to
do the following:

default target:

1. "make" the "cfiles/" directory contents.

2. Compile the source file in this directory, "main.c", into an object
code file.

3. Link all object code files into a executable named "c.exe".
Remember that the "C dependencies subtask" creates object files on which
"main.c" depends.

4. Copy "c.exe" into the directory "makefile_assignment/bin/".

clean target:

1. Clean the "cfiles/" directory.

2. Delete all object code files in this directory.

3. Delete all core dumps in this directory.

new target:

1. "make" the "clean" target.

2. "make" the "default" target.

=====
END: C subtask
=====

=====
BEGIN: C++ and archiving subtask
=====

The directory "makefile_assignment/cpp/" contains a C++ header file, "main.h",
and a single C++ file, "main.cpp", in addition to a lone subdirectory:

lib/

=====
BEGIN: Archiving subtask
=====

The directory "makefile_assignment/cpp/lib/" contains the following C++ source
and header files:

factorial.h sum_4_numbers.h summation.h
factorial.cpp sum_4_numbers.cpp summation.cpp

For this subtask ("Archiving subtask"), you must write a Makefile to do the
following:

default target:

1. Compile all source files into object code files.

2. Using the archiver "ar", archive the object code files into an
archive named "libFunctions.a".

clean target:

1. Delete the archive "libFunctions.a".

2. Delete all object code files.

3. Delete all core dumps.

new target:

1. "make" the "clean" target.

2. "make" the "default" target.

=====
END: Archiving subtask
=====

For this subtask ("C++ subtask"), you must write a Makefile to do
the following:

default target:

1. "make" the "lib/" directory contents.

2. Compile the source file in this directory, "main.cpp", into an
object code file.

3. Link all object code files into a executable named "cpp.exe".
Remember that the "Archiving subtask" creates an archive on which
"main.cpp" depends.

4. Copy "cpp.exe" into the directory "makefile_assignment/bin/".

clean target:

1. Clean the "lib" directory.

2. Delete the object code files in this directory.

3. Delete all core dumps in this directory.

new target:

1. "make" the "clean" target.

2. "make" the "default" target.

=====
END: C++ and archiving subtask
=====

=====
BEGIN: Java subtask
=====

The directory "makefile_assignment/java/" contains a single Java source file,
"Main.java", and no subdirectories.

For this subtask ("Java subtask"), you must write a Makefile to do the
following:

default target:

1. Compile the Java source file in this directory, "Main.java", into a
Java class file.

2. Copy "Main.class" into the directory "makefile_assignment/bin/".

clean target:

1. Delete the Java class files in this directory.

2. Delete all core dumps in this directory.

new target:

1. "make" the "clean" target.

2. "make" the "default" target.

=====
END: Java subtask
=====

This is the rest of "Makefile task", which has you producing yet another
Makefile to tie all the subtasks together. This Makefile must be capable of
carrying out the following:

default target:

1. "make" the targets "c", "cpp", and "java".

c target:

1. "make" the contents of the directory "makefile_assignment/c/".

cpp target:

1. "make" the contents of the directory "makefile_assignment/cpp/".

java target:

1. "make" the contents of the directory "makefile_assignment/java/".

clean target:

1. Clean the "c/" directory.

2. Clean the "cpp/" directory.

3. Clean the "java/" directory.

4. Delete all executables in the "bin/" directory.

5. Delete all core dumps in the "bin/" directory.

new target:

1. "make" the "clean" target.

2. "make" the "default" target.

=====
END: Makefile task
=====


2. Relevant commands, code, scripts, algorithms:

Won't be providing the .c, .cpp, .java files as they all compile just fine.
