# Generic Makefile for C/C++ Program

# Date:    2006/03/04 (version 0.1)

#          2007/03/24 (version 0.2)

#          2007/04/09 (version 0.3)

#

# Description:

# ------------

# This is an easily customizable makefile template. The purpose is to

# provide an instant building environment for C/C++ programs.

#

# It searches all the C/C++ source files in the specified directories,

# makes dependencies, compiles and links to form an executable.

#

# Besides its default ability to build C/C++ programs which use only

# standard C/C++ libraries, you can customize the Makefile to build

# those using other libraries. Once done, without any changes you can

# then build programs using the same or less libraries, even if source

# files are renamed, added or removed. Therefore, it is particularly

# convenient to use it to build codes for experimental or study use.

#

# GNU make is expected to use the Makefile. Other versions of makes

# may or may not work.

#

# Usage:

# ------

# 1. Copy the Makefile to your program directory.

# 2. Customize in the "Customizable Section" only if necessary:

#    * to use non-standard C/C++ libraries, set pre-processor or compiler

#      options to  and linker ones to 

#      (See Makefile.gtk+-2.0 for an example)

#    * to search sources in more directories, set to 

#    * to specify your favorite program name, set to 

# 3. Type make to start building your program.

#

# Make Target:

# ------------

# The Makefile provides the following targets to make:

#   $ make           compile and link

#   $ make NODEP=yes compile and link without generating dependencies

#   $ make objs      compile only (no linking)

#   $ make tags      create tags for Emacs editor

#   $ make ctags     create ctags for VI editor

#   $ make clean     clean objects and the executable file

#   $ make distclean clean objects, the executable and dependencies

#   $ make help      get the usage of the makefile

#

# The pre-processor and compiler options.

# .c indicates C source files, and others C++ ones.
