#
# 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 <MY_CFLAGS> and linker ones to <MY_LIBS>
# (See Makefile.gtk+-2.0 for an example)
# * to search sources in more directories, set to <SRCDIRS>
# * to specify your favorite program name, set to <PROGRAM>
# 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
#
#===========================================================================## Customizable Section: adapt those variables to suit your program.
##==========================================================================# The pre-processor and compiler options.
MY_CFLAGS = -I/home/anker/project/myssl/include# The linker options.
MY_LIBS = -L/home/anker/project/myssl/lib -lssl -lcrypto# The pre-processor options used by the cpp (man cpp for more).
CPPFLAGS = -Wall# The options used in linking as well as in any direct use of ld.
LDFLAGS =# The directories in which source files reside.
# If not specified, only the current directory will be serached.
SRCDIRS =# The executable file name.
# If not specified, current directory name or `a.out' will be used.

##==========================================================================# The source file types (headers excluded).
# .c indicates C source files, and others C++ ones.
SRCEXTS = .c .C .cc .cpp .CPP .c++ .cxx .cp# The header file types.
